AEROPRAKT-22LS Pilot Operating Handbook

A22LS-POH-04 

8.11  Seats and harness belts 

The airplane is equipped with adjustable seats with soft cushions. The seats are attached to

 

   

 

 

 

 

 

 

 

 

 

 

   

two transverse beams inside fuselage. The harness belts are of the 4-point type. Two

 

 

 

 

 

 

 

 

   

 

 

 

 

shoulder belts are passed over the shoulders from behind and are joined to the waist belts

 

 

 

 

 

 

 

 

 

 

 

   

 

 

 

with adjustable buckles. The lock is attached to the waist belts. 

Before climbing into the cockpit the pilots should adjust the seat position. After getting into

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

the seats the pilots should fasten the belt locks and adjust the belts to their size. 

The seats and harness belts properly adjusted and fastened do not restrict pilot motions

 

 

 

 

 

 

 

 

 

 

 

 

 

 

necessary to control the airplane and ensure pilots' safety in flight and during airplane

   

 

 

 

 

 

 

   

 

 

 

 

motion on the ground. 

8.12  Cockpit doors 

The cockpit doors consist of organic glass, attached to the metal tubular framework. The

 

 

 

   

 

 

   

 

 

 

 

 

doors are hinged on top and open upward. In their open and closed position the doors are

 

 

 

 

 

 

 

   

 

 

 

 

 

 

 

 

retained by pneumatic cylinders. Each door can be fixed in the closed position with a lock. 

Both left and right doors have air scoops for ventilation, de-misting of the glass and

 

 

 

 

 

 

 

 

 

 

   

 

 

 

providing pilot view for landing in poor visibility conditions (snow, rain, etc.). 

8.13  Baggage container 

The baggage container is located behind the pilot seats and is accessible from inside of the

 

 

   

 

 

 

 

 

   

 

 

   

 

cockpit – on ground and in flight as well. The baggage container may be one of two

   

 

 

   

 

 

 

 

 

 

 

 

   

 

designs: 

1. A soft fabric bag fixed on a rigid tubular framework. The container has an opening

 

 

 

 

 

   

 

 

 

 

 

 

 

 

clap with a zipper.  The weight of baggage in the soft container may not

 

   

 

 

 

 

 

 

 

 

 

 

 

exceed 20 kg (44 lb.) ; 

2. A rigid metal baggage compartment with a door on the left side of the fuselage.  The

 

 

 

 

 

   

 

 

 

 

   

 

 

 

weight of baggage in the rigid container may not exceed 30 kg (66 lb.).
