CAOs Flashcards
What is RAIM?
Receiver Autonomous Integrity Monitoring. A form of ABAS whereby a GNSS receiver processor determines the integrity of the GNSS navigation signals. Needs at least 1 additional satellite in the correct geometry, above and beyond those required for position estimation.
FDR operation
From taxiing under own power until conclusion of taxiing after landing
CVR operation
From start of use of checklist before starting engines until final checklist completion
Define: gross flight path
Flight path it is assumed an aeroplane will follow in a particular configuration following specified procedures in ambient conditions
Define: net flight path
Gross flight path reduced in elevation/extended in length by specified margins to allow for deterioration in aircraft performance or variations in pilot techniques
Take of climb performance - phase 1
Failure of critical engine recognised at V1
Airborne speed, gear down, to V2
Positive gross climb gradient
Take off climb performance - phase 2
V2, gear up, to acceleration altitude
2% gross climb gradient
Take off climb performance - phase 3
Acceleration to final take off climb speed
1.2% gross climb gradient
Take off climb performance - phase 4
Enroute configuration climbing
1.2% gross climb gradient
Take off climb performance - obstacle clearance
Net flight path clears by 35ft (50ft in turn)
Net flight path = gross flight path - 0.8%
Enroute climb performance - obstacle clearance
Net flight path clears by 1000ft within 5NM in VMC, or within distance based on accuracy of navaids used in IMC
Net flight path = gross flight path - 1.1%
At altitude for clearance, net flight path must be positive
If not, drift down procedures must clear by 2000ft
At aerodrome of intended landing after engine failure, net flight path must be positive in enroute configuration
Approach climb performance required
Critical engine inoperative, approach configuration, not more than 1.5Vs
2.1% gross climb gradient
Landing climb performance required
All engines operating, landing configuration, not more than 1.3Vs
3.2% gross climb gradient
Landing distance required factors - for determining MTOW/MLW
MTOW: x1.43 dry runway stopping distance for forecast dry runway/wet alternate runway
Where forecast wet destination runway, x1.67 dry runway stopping distance
MLW: x1.43 dry runway stopping distance
Fuelling of aircraft minimum distances
Sealed building - 5m
Stationary aircraft - 6m
Exposed public areas/unsealed building - 15m
