Final answer:
A good practice when flying a retractable gear airplane is to verify the gear position, use gear indicator lights and warnings, and perform regular maintenance and inspections.
Step-by-step explanation:
A good practice when flying a retractable gear airplane is to always verify that the gear is properly extended or retracted before takeoff and landing. This can be done by referring to the aircraft's checklist and visually inspecting the position of the gear.
Another good practice is to use the gear indicator lights and warning systems, if equipped, to ensure that the gear is in the correct position. Pilots should also monitor the aircraft's airspeed and altitude to ensure the gear is raised or lowered at the appropriate times during flight.
In addition, it is important to regularly perform maintenance and inspections on the retractable gear system to ensure its proper functioning and prevent any mechanical issues that could arise.
