1. Introduction to aircraft
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.
