Instructor and student pilots in a T-45 Goshawk aircraft
The two seating configurations for trainer, night / all-weather interceptor or attack aircraft are pilot and instructor side by side or in tandem. Usually the pilot is in front and the instructor behind. In attack helicopters, sometimes the pilot sits in back with the weapons operator in front for better view to aim weapons, as the AH-1 Cobra was a tandem cockpit redesign which produced a much slimmer profile than the much wider UH-1 Huey on which it was based. Attack aircraft and all-weather interceptors often use a second crew member to operate avionics such as radar, or as a second pilot. Bombers such as the B-58 Hustler seated 3 crew members in tandem. A common engineering adaptation is to lengthen the cockpit or fuselage to create a trainer with tandem seating from a single seater aircraft. Side-by-side seating
Tandem seat Gloster Meteor and side-by-side seat Hawker Hunter (trainer)
An alternative configuration is side-by-side seating which is common in large aircraft but less so in high performance jets. The B-47 and XB-52 bombers used fighter-style tandem seating but the final B-52 bomber series used a conventional side-by-side cockpit. The Grumman A-6 Intruder, General Dynamics F-111 or the Sukhoi Su-24 are examples of combat aircraft which use this configuration.
