Final answer:
Thrust reversers should be stowed gradually after landing to avoid sudden changes in thrust and potential engine damage.
Step-by-step explanation:
In aviation, thrust reversers are used to help slow down an aircraft after landing by redirecting the exhaust gases from the engines forward instead of backwards. The speed at which the thrust reversers should be stowed after landing varies depending on the specific aircraft and operating procedures.
However, it is generally recommended that the thrust reversers should be stowed gradually to avoid sudden changes in thrust and to prevent potential damage to the engines. Pilots typically follow the guidance provided by the aircraft manufacturer and the operating procedures specified by the airline.
