Landing Gear and Brakes Practice Test

The main idea here is recognizing what is actually inspected on a wheel and tire assembly versus items that belong to other aircraft systems. Tire tread depth is checked to ensure there is enough rubber for safe contact and that the tread hasn’t worn below minimum limits. Ply wear is looked for because when the tire’s internal plies or belts show wear or separation, the tire’s integrity is compromised and it can fail under load. Wheel cracks are a critical hazard since a cracked wheel can propagate and fail when stressed during takeoff, landing, or taxiing.

Antenna alignment, on the other hand, relates to the aircraft’s communication/navigation systems rather than the wheel and tire assembly, so it isn’t part of a typical wheel-and-tire inspection.
