1What is the A321 NEO maximum crosswind for engine start?
2At what altitude THS freezes (FLARE mode) A321 NEO ?
3What is the maximum FLAPS/SLATS speed CONF 1+F A320 CEO?
4What is the maximum FLAPS/SLATS speed CONF 1 A321 NEO?
5What is the Maximum Glide Slope angle for automatic Landing?
6What is the A321 NEO MTOW?
7Maximum bank angle that pilot can reach in Normal Law is 67º. What is the reason for this limitation?
Ответ по ключу базы
- C. While flying at this bank angle an aircraft with clean configuration will reach flight maneuvering load acceleration limit (+2.5 g).
8What is the definition of V2 speed?
Ответ по ключу базы
- B. Takeoff safety speed that the aircraft attains at the latest at an altitude of 35 ft with one engine failed, and maintains during the second segment of the takeoff.
9In case of continued take off with one engine failure, the SRS commands pitch to maintain a speed target at:
Ответ по ключу базы
- B. The highest of V2 or current speed (limited by V2+15 kt).
10Which of the following conditions must be met at MAX REC altitude?
11The OPT altitude requires a …… minimum cruise time, at a minimum cruise flight level of …… :
12Why is it necessary to keep sideslip centered using the rudder in case of engine failure?
13The OPT FL displayed on MCDU PROG page is computed by FMGS as a function of:
14There is REC MAX altitude displayed on MCDU PROG page. What buffet margin is provided at this altitude?
15VAPP must not be lower than with ATHR engaged:
16VREF equals to:
17What is the max. operating speed/max. operating mach number on A320/A321?
18In clean configuration VLS (lowest selectable speed) is:
19Why landing gear retraction is prohibited during windshear escape maneuver?
Ответ по ключу базы
- A. to avoid additional aircraft drag during operation of the landing gear doors
20What is the main function of rudder travel limiter?
Ответ по ключу базы
- B. to limit the rudder deflection as a function of speed to prevent tail structure damage
21In clean configuration the recommended one engine out speed is «Green dot». Why?
22What is the maximum speed at which the landing gear may be retracted on A-320?
23What is the maximum tail wind component for landing on A-320?
24What is the maximum tail wind component for takeoff on A-320?
25What is the maximum certified crosswind for take-off on A320\A321 NEO aircraft?
26What is the maximum demonstrated crosswind for take-off and landing on A320 CEO aircraft?
27How many percent of tailwind component is taken into account for takeoff performance calculation?
28What is the definition for VMCA?
Ответ по ключу базы
- C. Minimum control speed in flight at which the aircraft can be controlled with a maximum bank of 5°, if one engine fails, the other engine remaining at takeoff thrust (takeoff flap setting, gear retracted).
29What is the definition for VMCG?
Ответ по ключу базы
- C. Minimum speed, on the ground during takeoff, at which the aircraft can be controlled by only using the primary flight controls after a sudden failure of the critical engine, the other engine remaining at takeoff thrust.
30What speeds are considered as minimum maneuvering speeds?
31It is recommended to use flexible takeoff thrust:
Ответ по ключу базы
- C. In order to extend engine life and save maintenance costs.
