What is the maximum gap allowed between the VEN and turkey feathers?

The correct choice indicates that the maximum gap allowed between the Variable Exhaust Nozzle (VEN) and the turkey feathers is 1/4 inch. This specification is critical for ensuring the proper aerodynamic performance of the aircraft. Maintaining the correct gap is essential because if the gap is too large, it can lead to excessive drag, impacting fuel efficiency and overall performance during flight.

A gap of this size helps to ensure that the exhaust flow from the engine is properly directed and provides optimal thrust. It also helps in minimizing the risk of foreign object damage, as a wider gap could allow debris or other contaminants to enter the exhaust path. Adhering to this specification is part of the routine maintenance checks that Plane Captains must ensure are performed correctly to maintain aircraft readiness and operational integrity.
