On the recovery side of the flight deck, the adaptation to the aircraft loadout is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-WWII Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck.

QSN1 Why do almost all carriers using conventional aircraft have arrested-recovery systems? ANS1 conventional aircraft cannot decelerate on their own QSN2 What is the purpose of an arrested-recovery system? ANS2 to recover their aircraft QSN3 What do aircraft do when landing in order to stop on a short distance? ANS3 extend a tailhook that catches on arrestor wires stretched across the deck QSN4 What does a landing area angles off access allow an aircraft to do if if misses the arresting wires? ANS4 bolt QSN5 What can a "bolt" prevent an aircraft from doing? ANS5 crashing into aircraft on the forward deck
