When should the landing gear be retracted in the Beechcraft Travel Air BE-95?

The landing gear should be retracted after achieving a positive climb rate post-takeoff because this ensures that the aircraft is safely climbing away from the ground, indicating that the initial takeoff phase has been successfully completed. Retraction of the gear at this point optimizes aerodynamic efficiency, reduces drag, and enhances climb performance.

Immediately retracting the landing gear upon takeoff can be risky if the aircraft does not achieve a positive climb, as it could lead to a situation where the airplane loses significant lift. Waiting until the aircraft is safely climbing ensures that the pilot has adequate altitude and speed to handle any potential issues that might arise during the climb, thereby contributing to a safer takeoff procedure.

Reaching cruise altitude is not the appropriate time for gear retraction, as it should have already occurred during the climb. Finally, retracting the landing gear before touchdown for landing is not relevant to takeoff procedures and can lead to severe performance issues when attempting to land. Therefore, the correct procedure involves waiting until a positive rate of climb is established before retracting the landing gear.
