AOM I Performance Flashcards
The performance data are based on the following conditions:
— Pertinent power less installation, air bleed, and accessory losses. — Full temperature accountability within the operational limits for which the aircraft is certified.
The performance information is not valid if:
— The aircraft’s gross weight exceeds the appropriate maximum allowable limits. — Any of the limitations in Section 2 are not observed. A reading from any graph is obtained by extrapola-tion (i.e. using values of parameters outside the range given on the graph).
In the case of headwind components: the aircraft may be operated in reported components greater than 30 kt, but the effect of only
30 kt may be taken.
Equivalent Airspeed - EAS - The calibrated airspeed corrected fo
adiabatic compressible flow for the particular altitude. At sea level, the equivalent airspeed is equal to the calibrated airspeed.
Ground Speed - GS The aircraft speed in relation to the ground. It is the true airspeed corrected by
the wind speed.
Stopway - The performance software considers that the stopway surface presents the
same braking capabilities as the runway surface. Therefore, for the software use, the surface characteristics of the stopway cannot be substantially different from those of the runway, because no correction factor is considered by the software, concerning different aircraft braking capabilities on the stopway surface.
Clearway - An area beyond the runway, not less than ____ ft wide,
500 ft
Clearway - It is expressed in terms of a clear way plane extending from the end of the runway with an upward slope not exceeding ___%
1.25
Takeoff Run All Engines Operating
115% of the distance along the takeoff path, with all engines operating, from the start of takeoff to the mid point between lift off and the point at which the aircraft is 35 ft. above the takeoff surface.
Accelerate Stop Distance One Engine Inoperative (ASD/OEI)
The distance necessary to accelerate from a standing start to VEF with all engines operating, accelerate from VEF to V1 (assuming the critical engine fails at VEF), take the first action to abort the takeoff at V1 and come to full stop.
Minimum Control Speed On Ground - VMCG
The minimum speed on the ground at which, when the critical engine is suddenly made inoperative, it is possible to maintain control of the aircraft with the remaining engine at takeoff thrust, with use of the primary aerodynamic controls alone, and not deviate more than 30 ft. laterally from the centerline at any point during the takeoff run.
Minimum Control Speed In The Air - VMCA
The minimum speed at which, when the critical engine is suddenly made inoperative, it is possible to maintain control of the aircraft with the remaining engine at takeoff thrust, and maintain a straight flight with an angle of bank of not more than 5o.
Final Segment Speed - VFS
The speed to be achieved at the end of the acceleration segment and start of the final segment of the takeoff flight path, with one engine inoperative, landing gear retracted, and flaps retracted.
Approach Climb Speed - VAC
The go-around speed in the approach configuration, with one engine inoperative, approach flaps, and landing gear retracted.
Load Factor
The ratio between the aerodynamic force component acting normal to the longitudinal axis of the aircraft and the aircraft weight. A positive load factor is one in which the aerodynamic force acts upward with respect to the aircraft.
