What does the term "gear up landing" refer to?

The term "gear up landing" specifically refers to an unintentional landing with the landing gear retracted. This type of landing typically occurs when the pilot either forgets to deploy the landing gear or fails to observe that it’s still retracted before touchdown. The impact of the aircraft on the runway in this condition can cause significant damage to the aircraft, particularly to the fuselage and the underside of the wings.

Understanding this terminology is critical for pilots and aviation professionals since it highlights the importance of pre-landing checks and the potential consequences of not following proper procedures. Recognizing the correct terms enhances communication regarding landing gear operations, safety protocols, and emergency responses in aviation contexts.
