Aviation Safety
Aviation Safety
Air safety is a term encompassing the theory, investigation, and categorization of flight
failures, and the prevention of such failures through regulation, education, and training.
It can also be applied in the context of campaigns that inform the public as to the safety
of air travel.
Lightning
Boeing studies showed that airliners are struck by lightning twice per year on average;
aircraft withstand typical lightning strikes without damage.
Engine failure
An engine may fail to function because of fuel starvation (e.g. British Airways Flight
38), fuel exhaustion (e.g. Gimli Glider), foreign object damage (e.g. US Airways Flight
1549), mechanical failure due to metal fatigue (e.g. Kegworth air disaster, El Al Flight
1862, China Airlines Flight 358), mechanical failure due to improper maintenance
(e.g. American Airlines Flight 191), mechanical failure caused by an original
manufacturing defect in the engine (e.g. Qantas Flight 32, United Airlines Flight
232, Delta Air Lines Flight 1288), and pilot error (e.g. Pinnacle Airlines Flight 3701).
In a multi-engine aircraft, failure of a single engine usually results in a precautionary
landing being performed, for example landing at a diversion airport instead of
continuing to the intended destination.
                                                                                                     Page | 1
Structural failure of the aircraft
Composite materials consist of layers of fibers embedded in a resin matrix. In some
cases, especially when subjected to cyclic stress, the layers of the material separate
from each other (delaminate) and lose strength. As the failure develops inside the
material, nothing is shown on the surface; instrument methods (often ultrasound-based)
have to be used to detect such a material failure. In the 1940s several Yakovlev Yak-
9s experienced delamination of plywood in their construction.
Stalling
Stalling an aircraft (increasing the angle of attack to a point at which the wings fail to
produce enough lift) is dangerous and can result in a crash if the pilot fails to make a
timely correction.
Devices to warn the pilot when the aircraft's speed is decreasing close to the stall
speed include stall warning horns (now standard on virtually all powered aircraft), stick
shakers, and voice warnings. Most stalls are a result of the pilot allowing the airspeed
to be too slow for the particular weight and configuration at the time. Stall speed is
higher when ice or frost has attached to the wings and/or tail stabilizer. The more
severe the icing, the higher the stall speed, not only because smooth airflow over the
wings becomes increasingly more difficult, but also because of the added weight of the
accumulated ice.
Fire
Safety regulations control aircraft materials and the requirements for automated fire
safety systems. Usually these requirements take the form of required tests. The tests
measure flammability of materials and toxicity of smoke. When the tests fail, it is on a
prototype in an engineering laboratory rather than in an aircraft.
At one time, fire fighting foam paths were laid down before an emergency landing, but
the practice was considered only marginally effective, and concerns about the depletion
of fire fighting capability due to pre-foaming led the United States FAA to withdraw its
recommendation in 1987.
One possible cause of fires in airplanes is wiring problems that involve intermittent
faults, such as wires with breached insulation touching each other, having water
dripping on them, or short circuits. These are difficult to detect once the aircraft is on the
ground. However, there are methods, such as spread-spectrum time-domain
reflectometry, that can feasibly test live wires on aircraft during flight. [18]
Bird strike
Bird strike is an aviation term for a collision between a bird and an aircraft. Fatal
accidents have been caused by both engine failure following bird ingestion and bird
strikes breaking cockpit windshields.
Jet engines have to be designed to withstand the ingestion of birds of a specified
weight and number and to not lose more than a specified amount of thrust. The weight
and numbers of birds that can be ingested without hazarding the safe flight of the
aircraft are related to the engine intake area. [19] The hazards of ingesting birds beyond
the "designed-for" limit were shown on US Airways Flight 1549 when the aircraft struck
Canada geese.
The outcome of an ingestion event and whether it causes an accident, be it on a small
fast plane, such as military jet fighters, or a large transport, depends on the number and
weight of birds and where they strike the fan blade span or the nose cone. Core
damage usually results with impacts near the blade root or on the nose cone.
                                                                                                 Page | 2
The highest risk of a bird strike occurs during takeoff and landing in the vicinity
of airports, and during low-level flying by military aircraft, crop dusters and helicopters
for example. Some airports use active countermeasures, ranging from a person with
a shotgun through recorded sounds of predators to employing falconers. Poisonous
grass can be planted that is not palatable to birds, nor to insects that
attract insectivorous birds. Passive countermeasures involve sensible land-use
management, avoiding conditions attracting flocks of birds to the area (e.g. landfills).
Another tactic found effective is to let the grass at the airfield grow taller (approximately
12 inches (30 cm)) as some species of birds won't land if they cannot see one another.
Human factors
Human factors, including pilot error, are another potential set of factors, and currently
the factor most commonly found in aviation accidents Much progress in applying human
factors analysis to improving aviation safety was made around the time of World War
II by such pioneers as Paul Fitts and Alphonse Chapanis. However, there has been
progress in safety throughout the history of aviation, such as the development of the
pilot's checklist in 1937.[20] CRM, or Crew Resource Management, is a technique that
makes use of the experience and knowledge of the complete flight crew to avoid
dependence on just one crew member.
Pilot error and improper communication are often factors in the collision of aircraft. The
barriers to have an effective communication have internal and external factors. [21] The
ability of the flight crew to maintain situation awareness is a critical human factor in air
safety. Human factors training is available to general aviation pilots and called single
pilot resource management training.
Controlled flight into terrain (CFIT), and error during take-off and landing can have for
example causing the crash of Prinair Flight 191 on landing, also in 1972.
Pilot fatigue
The International Civil Aviation Organization (ICAO) defines fatigue as "A physiological
state of reduced mental or physical performance capability resulting from sleep loss or
extended wakefulness, circadian phase, or workload." [22] The phenomenon places great
risk on the crew and passengers of an airplane because it significantly increases the
chance of pilot error. Fatigue is particularly prevalent among pilots because of
"unpredictable work hours, long duty periods, circadian disruption, and insufficient
sleep".[24]These factors can occur together to produce a combination of sleep
deprivation, circadian rhythm effects, and 'time-on task' fatigue. [24] Regulators attempt to
mitigate fatigue by limiting the amount of hours pilots are allowed to fly over varying
periods of time. Experts in aviation fatigue [who?] often find that these methods fall short on
their goals.
.
Controlled flight into terrain
CFIT is a class of accidents in which an aircraft is flown under control into terrain or
man-made structures. CFIT accidents typically result from pilot error or of navigational
system error. Failure to protect ILS critical areas can also cause CFIT
accidents[dubious  discuss]. Another anti-CFIT tool is the Minimum Safe Altitude Warning
(MSAW) system which monitors the altitudes transmitted by aircraft transponders and
compares that with the system's defined minimum safe altitudes for a given area. When
the system determines the aircraft is lower, or might soon be lower, than the minimum
safe altitude, the air traffic controller receives an acoustic and visual warning and then
alerts the pilot that the aircraft is too low.[27]
Electromagnetic interference
The use of certain electronic equipment is partially or entirely prohibited as it might
interfere with aircraft operation,[28] such as causing compass deviations] Use of some
types of personal electronic devices is prohibited when an aircraft is below 10,000',
                                                                                                  Page | 3
taking off, or landing. Use of a mobile phone is prohibited on most flights because in-
flight usage creates problems with ground-based cells
Ground damage
Various ground support equipment operate in close proximity to the fuselage and wings
to service the aircraft and occasionally cause accidental damage in the form of
scratches in the paint or small dents in the skin. However, because aircraft structures
(including the outer skin) play such a critical role in the safe operation of a flight, all
damage is inspected, measured, and possibly tested to ensure that any damage is
within safe tolerances.[citation needed]
Volcanic ash
Plumes of volcanic ash near active volcanoes can damage propellers, engines and
cockpit windows.[31] [32] In 1982, British Airways Flight 9 flew through an ash cloud and
temporarily lost power from all four engines. The plane was badly damaged, with all the
leading edges being scratched. The front windscreens had been so badly "sand"
blasted by the ash that they could not be used to land the aircraft. [33]
Prior to 2010 the general approach taken by airspace regulators was that if the ash
concentration rose above zero, then the airspace was considered unsafe and was
consequently     closed.[34] Volcanic   Ash     Advisory     Centers enable   liaison
between meteorologists, volcanologists, and the aviation industry.[35]
Runway safety
Types of runway safety incidents include:
Airport design
Airport design and location can have a large impact on aviation safety, especially since
some airports such as Chicago Midway International Airport were originally built for
propeller planes and many airports are in congested areas where it is difficult to meet
newer safety standards. For instance, the FAA issued rules in 1999 calling for a runway
safety area, usually extending 500 feet (150 m) to each side and 1,000 feet (300 m)
beyond the end of a runway. This is intended to cover ninety percent of the cases of an
aircraft leaving the runway by providing a buffer space free of obstacles. Many older
airports do not meet this standard. One method of substituting for the 1,000 feet
(300 m) at the end of a runway for airports in congested areas is to install
an engineered materials arrestor system (EMAS). These systems are usually made of a
lightweight, crushable concrete that absorbs the energy of the aircraft to bring it to a
rapid stop. As of 2008, they have stopped three aircraft at JFK Airport.
Not all phases of flight are equally prone to accidents. Most accidents (55%) occur during
landing or take-off. Only 10% occur when the aircraft is en route.

                occurrences in aviation industry in India and abroad should be prepared
                and circulated to the concerned personnel.
5.5 The operators should bring out their own periodical safety journal.
                                                                                              Page | 22
The proactive programme is aimed to detect the weak areas in the system through
various measures as mentioned below which should be taken on regular basis. To
recognise weaknesses in a system or organisation and to take corrective measures
are the key factors to ensure safety in aviation. This way the potential hazards and
problem areas shall be detected and nipped in the earlier stages itself. Necessary
records shall be maintained by the operators of all the checks. While the operators
shall evolve their own detailed accident/incident prevention programme keeping in
view the nature and scope of their operations, the following salient measures shall
form part of their programme :-
 a) The operators should take steps for building safety culture in the organisation
     and declare their firm commitment to safety.
 b) The operators shall carry out periodically their internal safety audit of different
     divisions like operations, maintenance, commercial, security, ground support,
     etc. This shall be carried out by a dedicated group comprising of at least a
     senior pilot and an engineer.
 c) The value of data retrieved from the Cockpit Voice Recorders (CVR) and Digital
     Flight Data Recorders (DFDR) has been proven. Periodic monitoring of CVR
     and DFDR must be carried out by all operators. As the DFDR systems are
     enhanced with greater recorder capacity, they will become even more valuable
     tools not only for accident investigation but also accident prevention. The
     recorded data can be analysed for the purpose of checking deviations in flight
     parameters beyond acceptable limits which are critical to flight safety. The
     operator should develop suitable computer software to determine the
     deviations of different flight parameters beyond acceptable limits.
 e) Frequency of flight checks shall be increased during bad weather conditions like
     monsoon, fog, etc. Under such conditions crew should not hesitate to initiate a
     missed approach whenever the visual reference to the runway is lost. They
     should abandon the approach in weather conditions below the applicable
     minima and divert, if necessary.
 i) The critical operational areas shall be monitored closely so that these do not
     result in any serious safety hazard. Such areas are initial induction of new
     airline pilots, transition to a totally new type of aircraft like glass cockpit
     aircraft, operations to and from marginal runways, operations during monsoon,
     loading of aircraft under high ambient temperature and elevation conditions,
     operations to airfields located in mountainous terrain, airworthiness and
     operational control of leased aircraft, etc.
 j) Flight and Duty Time Limitations shall be laid down for the operating crew to
     ensure that the crew are not fatigued which may affect safety of operations.
     Rostering of the crew should be done keeping in view the flight and duty time
                                                                                             Page | 23
          limitation   requirements.   All scheduled   airlines  shall   establish
          electronic/computer based system for monitoring Flight and Duty Time
          Limitations. Also crew pairing should be done carefully for better crew
          coordination.
      k) In order to ensure that maintenance of aircraft is up to the mark, only the firms
           approved by DGCA as per CAR 145 or CAR Section 2, Series E Part IV
           system shall carry out maintenance of aircraft.
      l) The organization shall have adequate number of quality assurance staff which
          are able to monitor compliance with CAR 145/ CAR Section-2, Series E part
          IV.
      n) Regular checks shall be carried out by the operator to ensure that standard
          weights of crew and passengers are being used and loading of aircraft is
          within the limits as per RTOLW charts with proper centre of gravity. Load and
          trim sheets shall also be checked periodically to ensure their accuracy and
          their proper filling up for any irregularity. Check whether loading of the aircraft
          is being supervised.
      q) Regular statistical analysis of the accident and incident data shall be carried out
          to determine whether there has been an improvement or decline in level of
          safety. This analysis shall provide a useful hazard alerting technique.
Appendix D contains the guidance for the quantum of accident prevention programme.
7. SAFETY AUDIT

5. INTRODUCTION
        Nevertheless, it may be difficult for operators to make the best use of these
        guidelines, since they are distributed across a number of publications. Air
        operators who have yet to establish a flight safety documents system should
                                                                                        Page | 29
       utilize the information contained in this Attachment in establishing such a
       system. Air operators who have established such a system should verify that the
       functionality of their system is in compliance with the concepts outlined in this
       Attachment. DGCA inspectors will conduct a review of the flight safety
       documents system to ensure that it is effective in providing vital safety
       information to flight crew in a timely manner.
6. ORGANIZATION
       (i) Time critical information, e.g., information that can jeopardize the safety of
       the operation if not immediately available;
       (ii) Time sensitive information, e.g., information that can affect the level of
       safety or delay the operation if not available in a short time period;
       (iv) Reference information, e.g., information that is required for the operation
       but does not fall under (2) or (3) above; and
  c. Time critical information should be placed early and prominently in the flight
     safety documents system.
                                                                                            Page | 30
           recent terminology. All significant terms, acronyms and abbreviations included in
           the flight documents system should be defined.
3. DEPLOYMENT
4.         AMENDMENT
4.1        Operators should develop an information gathering, review and distribution
           system to process information resulting from changes that originate within the
           operator, including:
4.5        New information should be reviewed and validated considering its effects on the
           entire flight safety documents system.
4.6        The method of communicating new information should be complemented by a
           tracking system to ensure currency by operational personnel. The tracking
           system should include a procedure to verify that operational personnel have the
           most recent updates.
                                                                                               Page | 31
Procedure for medical examination of aircraft personnel for alcohol consumption
3. INTRODUCTION
1.1    It is a well-known fact that even when the blood alcohol levels are zero in the
       body, there could be some effect of hangover, which is mainly due to
       congeners. These congeners may take 15 to 18 hours to get dissipated and
       may produce ill effects for up to 36 hours depending upon the amount of alcohol
       consumed. Even 12 hours after a bout of drink, when blood alcohol level
       remains zero, there is decrement in task performance. Alcohol present in body
       even in small quantities jeopardises flight safety on several counts and is likely
       to adversely affect an aviator well into the hangover period.
1.2    Alcohol also interferes with the enzymatic cellular process or oxidation, causes
       hypoxia and reduces individuals tolerance with increase in altitude. It is known
       that a low alcohol blood level between 30 mg% to 50 mg% disturbs the sensor-
       motor, visual and cortical reaction. Consumption of alcohol results in significant
       deterioration of psychomotor performance and decreases the amount of mental
       capacity available to deal with many essential tasks involved in the conduct of
       safe flight. Should an emergency occur in-flight, the crew member under the
       influence of alcohol is not capable of dealing with the problem.
1.3    Two ounces of whiskey raises the alcohol level to 50 mg. The amount of alcohol
       in a can of beer is approx. the same as in a single mixed drink. Wine,
       champagne, ale and other alcoholic beverages have same effects as liquor,
       though the con centration of alcohol varies from one beverage to the other.
1.4    Therefore, in the present state of our know ledge, the level of blood alcohol
       compatible with safe flying is Zero, which is also recommended by ICAO. It
       is equally important to intensify the educational programme for crew
       members regarding the inherent dangers of flying after consumption of
       alcohol.
1.5    This Civil Aviation Requirement lays down the procedure to be followed for
       the breath-analyzer examination of the crew members for consumption of
       alcohol and actions to be taken by the operators. It also dwells on the
       procedure to be followed by the authorities concerned in the event of an
       accident.
1.6    This CAR is issued under the provisions of Rule 24 read with Rule 133A of
       the Aircraft Rules, 1937 for information, guidance and compliance by all
       concerned.
2. DEFINITIONS

       portable electronic devices have shown significant radio frequency
       emissions in excess of allowable levels within the frequency band of aircraft
       communication and navigation systems. The Boeing Co. have, therefore,
       suggested to the operators that any passenger electronic device which
       intentionally transmits radio signals should be prohibited for use by
       passengers at all times while on board airplane. These electronic devices
       include mobile/cellular phones, amateur radio transceivers, CB radios and
       transmitters that control devices such as toys, etc. The other type of
       passenger carry on electronic devices which is not an intentional transmitter
       of radio signals such as laptop computers, video cameras, electronic
       entertainment devices, electric shavers, etc. should also be prohibited for
       use during taxi, take-off, climb out, descent, final approach and landing
       phases of the flight in transmitting mode.
1.2     Federal Aviation Administration (FAA) and European Union Aviation Safety
       Agency (EASA) has determined that airlines can safely allow use of
       Portable Electronic Devices (PEDs) by passengers during all phases of
       flight and have provided the airlines with implementation guidance. The
       usage of PEDs is recommended only in flight/airplane mode during flight.
       The above decision is based on the advancement in technology and
       research on usage of mobile phones in air, inputs from airlines, aircraft
       manufacturers, travelling public, pilots, cabin crew and mobile technology
       companies.
1.3    In order to ensure safety of aircraft operation in flight, this Civil Aviation
       Requirement is issued under the provisions of Rule 29B read in conjunction
       with Rule 133A of the Aircraft Rules, 1937.
2. APPLICABILITY
2.1    This Civil Aviation Requirement is applicable to all persons on board all Indian
       Civil Registered aircraft and to all Indian operators engaged in scheduled and
       non-scheduled operations.

3.1   No person shall use any electronic device, which intentionally transmits
      radio signals like mobile/cellular phones, amateur radio transceivers, etc. at
      all times while on board an aircraft for the purpose of flight.
3.3   Passenger carry on electronic devices which are not intentional transmitter
      of radio signals such as laptop computers, video cameras, electronic
      entertainment devices, electric shavers, etc., if carried on board, shall not be
      used by any person, as announced by the cabin crew, inside the aircraft
      during taxi, take-off, climb out, descent, final approach and landing phases of
      flight.
3.4   All operators shall by suitable means address passengers on board their
      aircraft emphasizing the above mentioned prohibition regarding the use of
      mobile/cellular phones and other carry on electronic devices inside the
      aircraft in transmitting mode prior to commencement of the flight highlighting
      safety aspect.
3.5   Cabin crew, besides their other duties, during the flight shall keep a watch
      on the passengers to ensure compliance of the above prohibitory
      requirements.
3.6   Any violation of these requirements during the flight should be brought to the
      notice of the Commander by the cabin crew and recorded in the flight report
      book for subsequent action by the operator against the defaulting person.
