AMP - Aviation Maintenance Technician Powerplant Practice Exam

Which of the following statements is true regarding thrust reverser systems?

1. The reverser system must be able to withstand high temperatures, be mechanically strong, relatively light in weight, and reliable.

2. Engine thrust reversers on the aircraft usually will operate independently of each other.

3. Mechanical blockage system design permits a deployment position aft of the exhaust nozzle only.

4. Thrust reversers are primarily used to enhance the aircraft's lift during takeoff.

The correct answer is: The reverser system must be able to withstand high temperatures, be mechanically strong, relatively light in weight, and reliable.

The reverser system must be able to withstand high temperatures in order to effectively redirect the exhaust gases. If the system is not strong enough, it could potentially damage the aircraft or fail to function properly. Keeping the system relatively light in weight is important for maintaining the balance and overall weight of the aircraft. Reliability is crucial for safe operation and avoiding potential malfunctions. Option B is incorrect because engine thrust reversers on the aircraft are designed to operate simultaneously and symmetrically. This ensures equal deceleration and safe handling of the aircraft during landing. Option C is incorrect because modern thrust reverser systems can also be designed to deploy forward of the exhaust nozzle for improved performance. Option D is incorrect because while thrust reversers can provide some lift assistance, their primary function is to reduce the aircraft's ground roll during landing.
