When a dispatcher reviews a NOTAM indicating a runway's ILS glide slope is unusable, what is the primary operational impact?
Answer: Only precision instrument approaches to that runway are unavailable
An inoperative ILS glide slope removes the precision approach option, but non-precision and visual approaches may remain available if weather permits.
What is the function of an aircraft's stick shaker?
Answer: Alert the pilot of an impending stall by vibrating the control column
The stick shaker activates just before stall onset, providing a strong tactile and audio warning by vibrating the control column.
What does 'VMO/MMO' refer to in aircraft operations?
Answer: Maximum operating speed in knots / maximum operating Mach number
VMO is the maximum operating airspeed in knots and MMO is the maximum operating Mach number; exceeding either can cause structural damage.
On a transport aircraft, what does 'flight envelope protection' in fly-by-wire systems prevent?
Answer: Exceeding structural or aerodynamic limits such as stall, overspeed, and bank angle
Fly-by-wire envelope protection prevents pilots from commanding inputs that would exceed the aircraft's certified structural or aerodynamic limits.
What is the purpose of wing-mounted winglets on commercial jet aircraft?
Answer: Reduce induced drag by limiting wingtip vortex strength
Winglets reduce induced drag by minimizing the strength of wingtip vortices, improving fuel efficiency especially during cruise.
What aircraft system uses differential braking and nose wheel steering together to maintain directional control on the ground?
Answer: Ground steering system (NWS and differential braking)
On the ground, directional control is maintained through the nose wheel steering system for normal turns and differential braking for tighter maneuvering or crosswind correction.
Which aircraft system provides crew with real-time alerts for terrain proximity during approach and low-altitude flight?
Answer: Enhanced ground proximity warning system (EGPWS/TAWS)
EGPWS/TAWS uses GPS position, terrain databases, and flight parameters to provide early warnings of potential controlled-flight-into-terrain (CFIT) situations.
