What should brakes only be used for during towing or manual movement?

Brakes should only be used for an emergency stop during towing or manual movement to enhance safety. This usage is critical because the primary function of the brakes in such situations is to halt the aircraft in an urgent scenario where control may be compromised. Using brakes solely for this purpose minimizes the risk of skidding, unintentional movement, or shifting weight that could destabilize the aircraft.

In contrast, utilizing brakes for other functions, such as routine adjustments, positioning the aircraft, or preventing rollback, can lead to wear and could potentially introduce hazards or errors during towing operations. Focusing brake application solely on emergency stopping ensures that it is a controlled and deliberate action, reinforcing safety protocols and preserving the operational integrity of the aircraft.
