What should be done if the thrust reversers are inoperative during takeoff calculations?

The recommended action is to enter the information regarding the inoperative thrust reversers on the NON-STD CONFIG page. This step is essential for ensuring that the takeoff calculations reflect the aircraft's actual configuration and performance capabilities. When thrust reversers are not functional, the deceleration performance during landing will be affected, as the ability to redirect engine thrust to aid in slowing down is compromised. By noting this information on the NON-STD CONFIG page, it alerts all relevant personnel to the altered operational status of the aircraft.

This practice is vital because it allows flight crews and air traffic controllers to be aware of the aircraft's limitations due to the inoperative thrust reversers. It also serves as a formal record for any necessary operational adjustments and promotes adherence to safety protocols, ultimately enabling more secure flight operations.
