What does it mean to "terminate a flight"?

"Terminate a flight" refers to the conclusion of a flight operation, which specifically involves landing the glider safely and shutting down its systems. This phrase emphasizes the importance of concluding a flight with care to ensure the safety of both the pilot and the glider itself. Properly terminating a flight is a critical aspect of aviation safety, as it involves not only landing but also securing the glider for the next operation, checking for any issues, and ensuring that the environment is safe for exit.

The other options describe various stages or actions related to flight but do not accurately define the termination process. Taking off from the runway introduces a flight, whereas entering a new airspace suggests continuing operation in the airspace system. Starting a soaring session indicates the commencement of a gliding activity rather than its conclusion. Thus, the process of ending a flight is clearly encapsulated in safely landing and shutting down the glider.
