The Course Deviation Indicator (CDI) navigation source shown on the HSI
is set using the CDI softkey to select GPS, NAV1, or NAV2 inputs. The
course pointer is set on the GCU 479 FMS Keyboard by selecting the CRS
button and then selecting the desired course by turning the multi-function
knob. The selected course is displayed in a window above the upper RH 45°
index mark and will disappear approximately 3 seconds after the CRS select
knob stops turning.

Vertical Speed Indicator

Vertical Speed data is provided by the Air Data Computer and is shown as
a vertical tape along the right side of the altimeter on the PFD. The VSI scale
is graduated with major tick marks at 1000 and 2000 fpm in each direction
and minor tick marks at intervals of 500 feet The vertical speed pointer
moves up and down the fixed VSI scale and shows the rate of climb or
descent in digits inside the pointer. A reference notch at the RH edge of the
scale indicates 0 feet/min.
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.
Serials w/ MD302 Standby Attitude Module:
The Altitude Trend Bar is located along the right margin of the Altitude
Display. This feature is optional and can be turned on or off by the user.

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.
Refer to FAA Advisory Circular (AC) 43.13-1B for a list of occa-
sions requiring a compass swing. If a compass swing is required,
perform Operational Test - Magnetic Compass Calibration (refer

Wing Flaps

The electrically controlled, single-slotted flaps provide low-speed lift
enhancement. Each flap is manufactured of aluminum 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.
