Final answer:
During a pushback, a bypass pin is used to secure the nose landing gear in a forward direction to prevent it from steering during the pushback operation. The bypass pin is a metal pin that fits into a hole on the nose landing gear assembly of an aircraft. By securing the nose wheel, the bypass pin prevents the aircraft from inadvertently turning or veering off course during the pushback process.
Step-by-step explanation:
In aviation, a pushback is the process of moving an aircraft backwards from the gate, prior to taxiing.
During a pushback, a bypass pin is used to secure the nose landing gear in a forward direction to prevent it from steering during the pushback operation.
The bypass pin is a metal pin that fits into a hole on the nose landing gear assembly of an aircraft. It is an important safety measure as it ensures that the aircraft's nose wheel remains in a fixed position while being pushed back. By securing the nose wheel, the bypass pin prevents the aircraft from inadvertently turning or veering off course during the pushback process.
Once the pushback is completed, the bypass pin is removed before the aircraft proceeds with taxiing. This allows the nose wheel to rotate freely again and allows the aircraft to maneuver on its own power.
