Visual Approaches
Introduction:
    Visual approaches are an IFR procedure conducted under IFR in visual meteorological conditions and clear of clouds to the airport
          ATC: "[Callsign], fly [Instructions], vectors for visual approach to [Airport Name/Runway]"
    Visual approaches reduce pilot/controller workload and expedite traffic by shortening flight paths to the airport
    It is the pilot's responsibility to advise ATC as soon as possible if a visual approach is not desired
Visual Approach Conditions:
    Advise ATC if you can no longer maintain the following requirements:
      1. The airport or preceding aircraft in sight
                If the preceding aircraft is not in sight, the controller is responsible for aircraft separation
      2. Authorized under the control of the appropriate traffic control facility
                ATC may authorize this type of approach when is be operationally beneficial
                Can be requested by the pilot, or rejected in favor of a full IAP
                Pilot assumes traffic separation & obstruction clearance when proceeding visually
      3. Reported weather at the airport must be a ceiling at or above 1,000' and visibility at 3 SM or greater (VMC)
                Cloud clearance requirements of 14 CFR 91.155 are not applicable unless required by operation specifications
      4. When conducting visual approaches, pilots are encouraged to use other available navigational aids to assist in positive lateral and
           vertical alignment with the runway
    A visual approach is not an IAP and therefore has no missed approach segment
         If a go-around is necessary for any reason, aircraft operating at controlled airports will be issued an appropriate advisory
         clearance/instruction by the tower
         At uncontrolled airports, aircraft are expected to remain clear of clouds and complete a landing as soon as possible
         If a landing cannot be accomplished, the aircraft is expected to remain clear of clouds and contact ATC as soon as possible for further
         clearance
         Separation from other IFR aircraft will be maintained under these circumstances
    Authorization to conduct a visual approach is an IFR authorization and does not alter IFR flight plan cancellation responsibility see AIM,
    Canceling IFR Flight Plan, Paragraph 5-1-15
    Radar service is automatically terminated, without advising the pilot, when the aircraft is instructed to change to advisory frequency
    ATC Service is terminated when told to contact advisory frequency in the case of non-controlled fields
    NOT the same thing as a visual straight-in, however, may be flown as such if location permits
    For specifics on approach criteria from an ATC standpoint read 5-4-22 (c)
Operating to an Airport Without Weather Reporting Service:
    ATC will advise the pilot when weather is not available at the destination airport
    ATC may initiate a visual approach provided there is a reasonable assurance that weather at the airport is a ceiling at or above 1,000' and
    visibility 3 miles or greater

Operating to an Airport With an Operating Control Tower:
    Aircraft may be authorized to conduct a visual approach to one runway while other aircraft are conducting IFR or VFR approaches to
    another parallel, intersecting, or converging runway. ATC may authorize a visual approach after advising all aircraft involved that other
    aircraft are conducting operations to the other runway. This may be accomplished through use of the ATIS
         When operating to parallel runways separated by less than 2,500 feet, ATC will ensure approved separation is provided unless the
         succeeding aircraft reports sighting the preceding aircraft to the adjacent parallel and visual separation is applied
         When operating to parallel runways separated by at least 2,500 feet but less than 4,300 feet, ATC will ensure approved separation is
         provided until the aircraft are issued an approach clearance and one pilot has acknowledged receipt of a visual approach clearance, and
         the other pilot has acknowledged receipt of a visual or instrument approach clearance, and aircraft are established on a heading or
         established on a direct course to a fix or cleared on an RNAV/instrument approach procedure which will intercept the extended
         centerline of the runway at an angle not greater than 30°
         When operating to parallel runways separated by 4,300 feet or more, ATC will ensure approved separation is provided until one of the
         aircraft has been issued and the pilot has acknowledged receipt of the visual approach clearance, and each aircraft is assigned a
         heading, or established on a direct course to a fix, or cleared on an RNAV/instrument approach procedure which will allow the aircraft to
         intercept the extended centerline of the runway at an angle not greater than 30°
         The intent of the 30 degree intercept angle is to reduce the potential for overshoots of the final and to preclude side-by-side operations
         with one or both aircraft in a belly-up configuration during the turn-on
                                                                 Ads by

Separation Responsibilities
    If the pilot has the airport in sight but cannot see the aircraft to be followed, ATC may clear the aircraft for a visual approach; however, ATC
    retains both separation and wake vortex separation responsibility
    When visually following a preceding aircraft, acceptance of the visual approach clearance constitutes acceptance of pilot responsibility for
    maintaining a safe approach interval and adequate wake turbulence separation

Visual Straight-In Planning:
    Used for simplicity or emergency situations
         Generally, pilots desire to fly a 'standard' 3° glide-slope
    Fly checkpoints to touchdown
         10 NM = 3000' AGL
         9 NM = 2700' AGL
         8 NM = 2400' AGL
         7 NM = 2100' AGL
         6 NM = 1800' AGL
         5 NM = 1500' AGL
         4 NM = 1200' AGL
         3 NM = 900' AGL
         2 NM = 600' AGL
         1 NM = 300' AGL
    Miles x fpmile (Glide-slope) + Field Elevation = Altitude to Fly (AGL)
         3° glide-slope = 300 fpmile = 3° down with the velocity vector
         2.5° glide-slope = 250 fpmile, etc...

Responsibilities:
    Pilot Responsibilities:
        If a visual approach is not desired, advises ATC
        Complies with controller's instructions for vectors toward the airport of intended landing or to a visual position behind a preceding aircraft
        The pilot must, at all times, have either the airport or the preceding aircraft in sight
             After being cleared for a visual approach, proceed to the airport in a normal manner or follow the preceding aircraft
             Remain clear of clouds while conducting a visual approach
        If the pilot accepts a visual approach clearance to visually follow a preceding aircraft, you are required to establish a safe landing
        interval behind the aircraft you were instructed to follow. You are responsible for wake turbulence separation
        Advise ATC immediately if the pilot is unable to continue following the preceding aircraft, cannot remain clear of clouds, needs to climb,
        or loses sight of the airport
        Be aware that radar service is automatically terminated, without being advised by ATC, when the pilot is instructed to change to advisory
        frequency
        Be aware that there may be other traffic in the traffic pattern and the landing sequence may differ from the traffic sequence assigned by
        approach control or ARTCC

        Do not clear an aircraft for a visual approach unless reported weather at the airport has a ceiling at or above 1,000' and visibility is 3
        miles or greater
            When weather is not available for the destination airport, inform the pilot and do not initiate a visual approach to that airport unless
            there is reasonable assurance that descent and flight to the airport can be made visually
        Issue visual approach clearance when the pilot reports sighting either the airport or a preceding aircraft which is to be followed
        Provide separation except when visual separation is being applied by the pilot
        Continue flight following and traffic information until the aircraft has landed or has been instructed to change to advisory frequency
        For all aircraft, inform the pilot when the preceding aircraft is a heavy. Inform the pilot of a small aircraft when the preceding aircraft is a
        B757
            Visual separation is prohibited behind super aircraft
        When weather is available for the destination airport, do not initiate a vector for a visual approach unless the reported ceiling at the
        airport is 500' or more above the MVA and visibility is 3 miles or more. If vectoring weather minima are not available but weather at the
        airport is ceiling at or above 1,000' and visibility of 3 miles or greater, visual approaches may still be conducted
