Definitions Flashcards
Accelerate stop distance
Length of take off run available plus any available stopway
Adequate aerodrome
Aerodrome that is suitable for the aircraft to divert to, it has category 4 or higher firefighting abilities with 30 minutes prior notice and meets the requirements prescribed in part 121
Approach control
ATS for the arriving and departing aircraft
Area navigation
Method of navigation that permits aircraft operation on any desired flight path within the coverage of ground or spaced based navigation methods, or within the limits of self contained navigation systems, or a combination
Augmented crew
Crew on an aeroplane that is compromised of more than the minimum crew required by the certification
CAT II precision approach
Precision instrument approach with decision height between 100-200 feet and a runway visual range of not less than 300 meters
CAT III A vs. CAT III B vs. CAT IIIC precision approaches
A: Minimum decision height = 0ft - 100ft, Minimum RVR= 175m
B: minimum decision height = 0ft - 50ft, minimum RVR= 50m- 175m
C: no minimum decision height or RVR
Contaminated runway
25% of runway surface area in the required landing distance is covered by surface water, slush or loses snow more than 3mm in depth, or there is any ice on the runway
Decision altitude
Height AMSL on an instrument approach that a missed approach must be conducted if visual reference has not been established
Decision height
The height AGL that a missed approach must be commenced on an instrument approach if visual reference has not been established
Escorted passenger
Passengers requiring the personal attendance of an escort during an ATO
Instrument approach procedure
A series of predetermined manoeuvres by reference to the flight instruments with specified protection from obstacles from the initial approach fix, start of the arrival route to a point where landing can be completed; or if landing cannot be completed continue to a holding position.
Instrument flight
Aircraft is piloted with sole reference to the instruments, without external reference points
Instrument time
Instrument flight time plus any time that a pilot is practicing simulated instrument flight on an approved mechanical device
Mach number
Ratio of airspeed to the speed of sound
MDA
Minimum descent altitude: the minimum height AMSL that you can descend to on a non precision approach or circling approach without visual reference
MDH
Minimum descent height: the minimum height AGL that you can descend to on a non precision approach or circling approach without visual reference
Minimum safe altitude
The minimum safe altitude you can descent to that gives terrain clearance within the total area of navigation tolerance
Precision approach procedure
Instrument approach procedure that uses guidance in the azimuth and the glide path
Pressure altitude
Atmospheric pressure, expressed in terms of altitude, which corresponds to the pressure in the standard atmosphere
Reporting point
Specific geographic location in relation to which aircraft position can be reported.
Solid triangle means it is required, hollow triangle means it is is not required
Required navigation performance
Statement of the navigation performance accuracy necessary for the operation within a defined area of airspace
A containment value in nm from the intended position that the aircraft can remain within 95% of the time
RVR
Runway visual range: range that a pilot can see the runway surface markings, or lights determining the runway and centreline
ZFT simulator
Zero flight time simulator: simulator that has full motion and has its own registration. You do not need to fly the actual aircraft before gaining approval to operate it.
