(AOM) Definitions (Deep Dive) (AOM 1.3.0) Flashcards
(78 cards)
Accelerate Stop Distance Available (ASDA)
The runway plus stopway length declared available and suitable for the acceleration and deceleration of an aircraft rejecting takeoff. ASDA may be longer than the physical length of the runway when a stopway has been designated available by the airport operator, or it may be shorter than the physical length of the runway if necessary to use a portion of the runway to satisfy runway design standards. ASDA is the distance used to satisfy the aircraft accelerate-stop distance performance requirements.
Abnormal Procedure
Procedure requiring use of special systems or alternate use of normal systems. Applying the procedure maintains an acceptable level of airworthiness, or reduces the operational risk resulting from a failure.
Accelerate-Stop Distance
The distance required to accelerate the aircraft, recognize an engine failure so that the first action to stop (brake application) is initiated at V1, and then bring the aircraft to a full stop.
Abnormal Situation
A situation that has the potential of escalating to emergency if corrective action is not taken.
Actual Landing Distance (ALD)
Distance used in landing and braking to a complete stop (on a dry runway) after crossing the runway threshold at 50 ft.
Adjusted VREF
Sum of VREF plus additives due to non-normal situation or condition (e.g., partial flap configuration).
ALT
Synonymous with Altitude Alerting Device (AAD).
Assigned SID
The departure procedure contained in an ATC clearance.
Baro-VNAV
An RNAV system that uses barometric altitude information to present vertical guidance.
Basic Empty Weight (BEW)
Empty weight of the aircraft (includes required and optionally installed equipment).
Basic Operating Weight (BOW)
Sum of BEW and non-variable weight.
Blast Pads and Overruns
Surfaces adjacent to the ends of a runway, not to be confused with a clearway or stopway.
Clearway (CWY)
A defined rectangular area beyond the end of the runway, cleared or suitable for use in lieu of runway to satisfy takeoff distance requirements.
Contaminated Runway
A runway is considered contaminated when more than 25% of the required runway length, within the width being used, is covered by:
* standing water deeper than 1/8 in., or
* any depth of frost, ice, snow, slush.
If the section of the runway surface that is covered by standing water is located where rotation and liftoff will occur, or during the high speed part of the takeoff roll, the retardation effect is more significant than if it were encountered early in takeoff at low speed. In this situation, it is better to consider the runway contaminated rather than wet.
Contingency Fuel
Fuel quantity added to XTR line on flight release at request of PIC to allow for extended endurance for known or anticipated conditions.
Continuous Descent Final Approach (CDFA)
An approach at an angle that results in continuous descent on the final approach segment of a non-precision approach.
DAAP (Destination Airport Analysis Program)
DAAP allows the planned landing distance (factored) to be up to 80% of the available runway length, instead of the regulatory standard of 60%.
Declared Distances
All 14 CFR Part 139 airports report declared distances for each runway. Declared distances for a runway represent the maximum distances available and suitable for meeting takeoff and landing distance performance requirements. Such declared distance may be longer or shorter than the physical length of the runway shown on charts or other publications or in navigation databases (FMS).
Derived Decision Altitude (DDA)
A Derived Decision Altitude is calculated by adding 50 ft to the published MDA or DA when published in lieu of MDA on non-precision approach. Ensures the aircraft will not descend below MDA if missed approach is initiated.
Digital Copy
Documents or information displayed on an EFB.
Divergence Point
Any point where actual flight path departs from the prescribed flight path of the Engine-Out Procedure (EOP) (e.g., accepting ATC vector, on course turn after 400 ft AFE from uncontrolled field).
EICAS
Synonymous with EIS/CAS.
Electronic Checklist (ECL)
Information displayed in aircraft avionics system.
Emergency Situation
Situation that requires immediate response and landing at a suitable airport.
