Introduction to Airplane

The Sling 4 TSi is a four seat

(two pairs of side-by-side seats)

, single

engine, fixed tricycle undercarriage

(with steerable nose wheel)

aluminium aircraft of semi-monocoque construction with a

conventional low wing design.
The aircraft design is based upon the FAA FAR 23 certification

standards and has a maximum all up weight of 950 kg (2,095 lb).

Notwithstanding that the aircraft design is based upon the FAA FAR 23

certification standards, the aircraft has not been proven to comply

with all the provisions of the standard.
The Sling 4 TSi is intended chiefly for recreational and cross-country

flying. It is not intended for aerobatic operation. This Pilot Operating

Handbook has been prepared to provide pilots with information for

the safe and efficient operation of the Sling 4 TSi.
