QFE is referred to as Atmospheric pressure at aerodrome elevation

QNH. The altimeter sub-scale setting to obtain elevation when on the ground.
QFF is a Q code. It is the MSL pressure derived from local meteorological station
conditions in accordance with meteorological practice.[1][2] This is the altimeter setting that
is intended to produce correct altitude indication (i.e., no error) on an altimeter at the
actual sea level elevation, while QNH is intended to have no error at the station elevation
(or, especially when applied within a region with a relatively small range of surface
elevations, at the altitudes close to the surface elevation within the region).[3]
ICAO Q code
1. The meanings of the Aeronautical Code signals were assigned by ICAO.
Since, in general, only stations of the Aeronautical Service will have available copies of the Aeronautical
Code it should not be used in communications with stations of other services unless it is known that the
station concerned is familiar with the code.
2. Q signals may be amplified or completed by the addition of appropriate location indicators, approved
abbreviations, signals, call signs, figures or numbers.
2.1. The information necessary to complete a signification, as indicated by a blank space, shall be given
except when:
(a) The blank spaces are enclosed within parentheses to indicate that their completion is optional.
(b) an alternative meaning shown in parentheses is selected and the blank space in this alternative
meaning is completed.
2.2. The information used to complete the blank spaces shall be sent immediately after the Q signal in
the sequence shown in the signification.
2.3. Expressions or words in parentheses which do not include blank spaces have the following
significance:
(a) when following a blank space, the explanation of the information to be used in filling in the preceding
blank.
(b) when following a word or expression, an alternative to the word or expression.
2.4. Q signals shall be read as a question when followed by a note of interrogation signal (IMI). When a
signal is used as a question and is followed by additional or complementary information, the note of
interrogation signal shall follow this information.
2.5. Q signals that are capable of being given an affirmative or negative sense shall be read in the
appropriate sense when immediately followed by the signal YES in the case of the affirmative or the
signal NO in the case of the negative.
2.6. Q signals used in the aeronautical service that are capable of being given the sense of an order shall
be read in this sense when immediately followed by the signal ORD.
2.7. Q signals with numbers alternative significations shall be followed by the appropriate figure to
indicate the exact meaning intended. This figure shall be sent immediately following the Q signal.
2.8. All times shall be given in Greenwich Mean Time (GMT) unless otherwise indicated in the question or
reply.
