Model GA8-TC 320 Description
7.4 INSTRUMENT PANEL
Although the instrument panel spans the width of the cockpit, all instruments are on the left hand
side in front of the pilot. Radio and navigation aids are stacked in line with the centre console
but are canted towards the pilot for ease of observation. The right hand side may contain any
additional radios or a group of ight instruments for use by a ight instructor when the aircraft is
tted with dual controls for training purposes.

7.5 GROUND CONTROL
The GA8-TC 320 aircraft is tted with mechanical linkage from the rudder pedals to the nose
wheel. This gives the ground handling a direct feel. The minimum turning radius is approximately
half the wing span. Ground handling is via a towbar attached to two pegs located just above the
nose wheel fork. The aircraft is easily manoeuvred by one person provided the aircraft is empty.
7.6 WING FLAP SYSTEM
The wing aps are of the single slotted type with three selectable positions; Up, 14° and 38°.
The position of the aps is determined by notches engaged by the operating lever on the right
hand side of the pilot’s seat. The ap handle acts as the ap position indicator. The selected
position can be easily conrmed by visual observation.
The ap system is cable and push rod actuated. The aps are extended by cable tension
provided by the ap operating lever acting on a torque tube and push rod mechanism. They
are retracted by a return cable in opposition to the extension mechanism. The ap structure
has been designed to withstand all air loads but has not been designed as a grab handle for
passengers getting in and out of the rear cabin door. The ap skin is thin sheet aluminium and
is easily creased.
