What is the function of a torque tube in an aircraft control system?
Answer: Transmit rotational motion to move control surfaces
A torque tube transmits rotational (torsional) loads to actuate control surfaces such as flaps or ailerons.
What is the main advantage of a wet wing fuel tank design compared to a bladder tank?
Answer: Higher fuel capacity for the same structural weight
Wet wing tanks use the sealed wing structure itself as the fuel tank, maximizing usable volume without the weight penalty of a separate bladder or tank.
An aircraft uses a push-pull tube control system. What is the primary advantage over a cable system?
Answer: Ability to transmit both tension and compression loads
Push-pull tubes can carry both compressive and tensile loads, providing positive control in both directions without requiring turnbuckles or take-up devices.
Which FAA document specifies the minimum inspection requirements for a particular aircraft's airframe?
Answer: The aircraft's FAA-approved Maintenance Manual
The FAA-approved Maintenance Manual (or Airworthiness Limitations section) for a specific aircraft specifies its mandatory inspection requirements.
What type of damage is characterized by a series of parallel scratches or grooves on a mating surface caused by relative motion?
Answer: Fretting
Fretting damage occurs when two surfaces in contact undergo small oscillatory relative motion, producing parallel scratches and wear debris.
When bleeding a hydraulic brake system using the gravity method, fluid is introduced at which point?
Answer: At the master cylinder reservoir
In gravity bleeding, fluid is added at the master cylinder reservoir and allowed to flow by gravity through the system, pushing air out at the bleeder valves.
What is the purpose of a shimmy damper on nose wheel landing gear?
Answer: Dampen rapid oscillations of the nose wheel about its vertical axis
A shimmy damper is a hydraulic or friction device that dampens rapid side-to-side oscillations (shimmy) of the nose wheel.
