Magnetic Compass; Wing Flaps; Flap Control Switch - Cirrus SR22 Pilot's Operating Handbook And Flight Manual

Section 7 Cirrus Design
Systems Description SR22
Vertical speed must exceed 100 feet/min before digits will appear in
the VSI pointer. If the rate of ascent/descent exceeds 2000 fpm, the
pointer appears at the corresponding edge of the tape and the rate
appears inside the pointer.

Magnetic Compass

A conventional, internally lighted, liquid filled, magnetic compass is
installed on the cabin headliner immediately above the windshield. A
compass correction card is installed with the compass.

Wing Flaps

The electrically controlled, single-slotted flaps provide low-speed lift
enhancement. Each flap is manufactured of aluminium and connected
to the wing structure at three hinge points. Rub strips are installed on
the top leading edge of each flap to prevent contact between the flap
and wing flap cove. The flaps are selectively set to three positions: 0%,
50% (16°) and 100% (35.5°) by operating the FLAP control switch.
The FLAP control switch positions the flaps through a motorized linear
actuator mechanically connected to both flaps by a torque tube.
Proximity switches in the actuator limit flap travel to the selected
position and provide position indication.
The wing flaps actuator, flap control switch and indicator lights are
powered by 28 VDC through the 10-amp FLAPS circuit breaker on the
NON ESS BUS.

Flap Control Switch

An airfoil-shaped FLAPS control switch is located at the bottom of the
vertical section of the center console. The control switch is marked
and has detents at three positions: UP (0%), 50% and 100%. The
appropriate V speed is marked at the Flap 50% and 100% switch
FE
positions. Setting the switch to the desired position will cause the flaps
to extend or retract to the appropriate setting. An indicator light at each
control switch position illuminates when the flaps reach the selected
position. The UP (0%) light is green and the 50% and 100% lights are
yellow.
