7.4.3 Cabin Heat

For the cabin heating, ram air is heated in a shrouded chamber at the exhaust muffler

and flows through a duct into the cabin if the heat control valve is opened. Behind the

firewall, the heated air is subdivided for windshield defrosting and cabin heating.

The control element to open or close the heat control valve is located in the control

panel below the midsection of the instrument panel.

7.4.4 Cabin Ventilation

Two adjustable ventilation nozzles are located on both sides of the instrument panel to

supply the cabin with fresh air. The amount and direction of fresh airflow can be

adjusted individually for each seat by pivot-mounted nozzle outlets. If required, the sash

windows of the canopy may additionally be opened for the ventilation of the cabin.

7.5 UNDERCARRIAGE

The landing gear consists of a steerable nose gear that is equipped with a shock

absorber and a main landing gear. To provide precise control of the aircraft while taxiing

on ground, the nose gear strut is directly linked with the rudder pedals.

The main gear struts are designed as leaf springs to absorb the touch-down loads

during landing. Hydraulically actuated disc brakes are provided on the main gear wheels

which are activated by tilting the rudder pedals in the forward direction.

Because of the robust landing gear and the 5.00 x 5 wheels on the nose and main

landing gear in combination with sturdy wheel fairings, the aircraft is suitable for the

operation on airfields with grass runway.

7.5.1 Nose Landing Gear and Nose Gear Steering

The nose landing gear consists of a tubular steel strut that is attached pivot-mounted to

the engine frame support.

A portion of the nose gear loads is directly transferred into the front structure of the

fuselage via the lower attachment fittings of the engine frame support by two support

struts.

Good shock absorption and suspension characteristics are provided by a shock

absorber unit equipped with stacked rubber springs which acts directly on the nose

wheel fork.

The steering of the nose wheel is accomplished by a spring loaded steering rod

assembly that connects the nose gear steering arm at the upper end of the nose gear
