KPMD Pilot Initial Qualification Exercise Practice Test

When the landing gear lever isn’t in the detent during preflight, it signals a possible gear extension/lock fault. That’s a safety-critical issue that must be addressed before flight. The two groups to notify immediately are the Aircraft Commander and Maintenance Personnel. The Aircraft Commander (the pilot in command) is responsible for flight safety and must be informed of any abnormal condition that could affect takeoff, so a decision can be made—often to delay or cancel the flight until the issue is resolved. Maintenance Personnel are needed to diagnose and repair the gear system, verify proper extension and locking, and re-test to ensure the gear is ready for flight. Other groups listed aren’t the immediate focus for this mechanical fault. ATC or Dispatch aren’t the ones to perform or authorize maintenance fixes on the aircraft, and while ground crew or a supervisor may be involved in other tasks, they don’t replace the need for the aircraft commander’s authority and maintenance personnel’s technical action.
