deceleration rate when the thrust levers are retarded to idle above 65 knots.
B. The RTO function automatically applies maximum brake pressure when a thrust reverser lever is moved to idle reverse.
C. The RTO function automatically applies maximum brake pressure when the thrust levers are retarded to idle above 85 knots groundspeed.
D. The RTO function automatically applies maximum brake pressure when the thrust levers are retarded to idle above 85 knots indicated airspeed.
C. The RTO function automatically applies maximum brake pressure when the thrust levers are retarded to idle above 85 knots groundspeed.
If center hydraulic system fluid quantity is low, is it likely that the gear actuation system has lost all available pressure sources?
A. No, if center hydraulic system fluid quantity is low, the center system fluid is isolated to provide an alternate extension source.
B. Yes, if center hydraulic system fluid quantity is low, the alt. extension system has lost all available pressure sources.
C. No, if center hydraulic system fluid quantity is low, the C1 demand pump is isolated from the center hydraulic system to provide gear extension and nose wheel steering source.
D. Yes, if center hydraulic system fluid quantity is low, the alternate gear actuation levers must be used.
A. No, if center hydraulic system fluid quantity is low, the center system fluid is isolated to provide an alternate extension source.
