Final answer:
The takeoff configuration warning activates when either the flaps are not in the required takeoff position or the landing gear is not down and locked, with the thrust levers advanced above 70% N1. The correct answer is c) Both a and b.
Step-by-step explanation:
The takeoff configuration warning is a critical safety feature in aircraft systems designed to alert pilots of potential issues that could affect the safe takeoff of an aircraft. This warning will activate under certain conditions when the thrust levers are advanced above 70% N1, which is indicative of the aircraft preparing for takeoff.
The correct answer to the question is c) Both a and b. The warning will activate if:
- The flaps are not set to the required takeoff position.
- The landing gear is not retracted (although retracting the landing gear would typically occur after takeoff, the system checks that it is down and locked for takeoff).
Pilots need to confirm that the aircraft is in the correct configuration for takeoff to ensure flight safety. If the takeoff configuration warning activates, they must abort the takeoff and correct any configuration issues before attempting to take off again.
