7.11.2 Propeller
The installed propeller is a model MTV 7-A / 170-51 with constant-speed-
control-unit.
• Electrically-adjustable 3-Blade Constant-
Speed Propeller, continuously
adjustable from T/O-setting to glider-setting, electronic constant-speed
control, control unit: P120-A (DB)
• Forged/milled hub made of light-alloys. Blasted and anodized surface-finish
• Blades made of wood-composites with a liner made of fiber-composites,
edge-guard at the outer edges of the propeller made of stainless-steel,

The propeller-pitch is continuously adjustable from the T/O-setting to the cruise-

motor is controlled by the automatic propeller-control-unit, which selects the
corresponding propeller-pitch according to the power-setting and air-speed.
7.11.2.1 Propeller-Pitch-Control
The automatic propeller-control-unit P-120-A is operated with the control-
elements located in the lower center area of the instrument-panel.
To adjust the control-unit use the two flip-switches and the rotary-switch. The left
flip-switch can be set to the „AUTO“ and „MANU“ (manual) positions. At "MANU"
the right flip-switch can be set to „HIGH RPM“ and „FEATHER“. Select the
propeller-RPM with the rotary-switch.
