Overview
The flight crew seats are for the pilot and copilot. They are installed in the flight compartment. The pilot seat is on the left, and the copilot seat is on the right. The flight crew seats are the same for the pilot and the copilot. The seat controls are on opposite sides except for the lumbar control which is on the left side of both seats.
Inertia Reel Control
The inertia reel control is for the adjustment of the shoulder straps. It is also referred to as the inertia reel lock. It has two positions of control, locked and released. In the locked position the shoulder straps length is set. When the inertia reel control is released, the shoulder straps can move freely; however, sudden acceleration tightens the shoulder straps and locks them. The control is connected to the inertia reel with a flexible cable that is sealed in the rear of the seat. The inertia reel lock is located on the rear of the seat on the inboard side.
Inertia Reels
There are two inertia reels which, as an assembly, adjust the shoulder straps. See Flight Crew Seats - Back. They are controlled by the inertia reel control. The inertia reels are located in the center, top rear part of the seat. Each inertia reel contains a shoulder strap and has a spring lock device.
The spring lock device locks the shoulder straps in position when there is a sudden forward, vertical movement. It also locks the shoulder straps during acceleration. The inertia reels remain locked until the load on the shoulder straps decreases.
Safety Straps
The safety straps are an assembly of five different straps. The five safety straps connect to a circular quick release buckle, which has a pad. There are two shoulder straps which are attached at the upper end to the inertia reels. There are two waist straps and a crotch strap which are attached at the lower end of the seat.

The armrests are also adjustable to a maximum of between 16 degrees down and 12 degrees up. A wheel below each armrest permits the pilot/copilot to adjust the angle of the armrest.
