GFC 700, TAWS and POST MODIFICATION FLIGHT TEST PROCEDURE
All performance tolerances specified in the following in-flight checks assume smooth air. The pilot must
be thoroughly familiar with the GFC 700 by studying the following:
•
G1000 in Hawker Beechcraft King Air C90A/GT Cockpit Reference Guide, Garmin P/N 190-
00664-00.
•
G1000 Airplane Flight Manual Supplement Hawker Beechcraft King Air C90A/GT,

8.1
Before Take-Off
1. Press the GO AROUND button on the left throttle. Verify ‘TO’ is annunciated on PFD1 and PFD2
for both PITCH and ROLL modes and the command bars indicate 8.6 degrees nose up and
wings-level.’
8.2
Initial Engagement
1. Climb to a safe altitude in VFR conditions and establish 185 KIAS in straight and level flight. Pre-
selected altitude should be set at 2000-ft above the altitude selected for this step.
2. Press
the
FD
key on the AFCS mode controller to display the Flight Director in the default ‘PIT’
and ‘ROL’ modes, ‘
ALTS’
will be in armed mode (white annunciation). Verify that the Flight
Director command bars are synchronized with the aircraft attitude in both pitch and roll at the time
of Flight Director engagement.
If the bank angle is less than 6
°
, ROL mode will command wings-level. If the bank angle is 6
°
or
greater, the bank angle at the time of ROL mode activation will be held, up to a maximum of 25
°
.
3. Press
the
AP
key on the AFCS mode controller to engage the autopilot. The autopilot will hold
the commanded pitch attitude within
±
2
°
and the roll attitude within
±
2
°
.
8.3
Vertical Speed (VS) Mode
1. With the Autopilot engaged in straight and level flight, press the
VS
key on the AFCS mode
controller to select Vertical Speed mode. A green ‘
VS’
, green reference vertical speed (aircraft’s
vertical speed when the VS button was pressed), and a white ‘ALTS’ will be annunciated in the
pitch window. Any convenient lateral mode may be used.
2. Climb the aircraft at 500 feet per minute using the NOSE UP/DN wheel on the AFCS mode
controller. Monitor proper power settings to maintain safe operating airspeed.
3. The autopilot will hold the commanded rate of climb within
±
50 feet per minute. Change the
vertical speed reference to climb at 700 feet per minute. The autopilot maintains the commanded
rate of climb within
±
50 feet per minute. Allow the autopilot to capture the pre-selected altitude.
4. Using the ALT SEL knob on the AFCS mode controller, select an altitude 2000-ft below the
aircraft’s current altitude.
5. Press
the
VS
key on the AFCS mode controller and select a descent of 500 feet per minute using
the NOSE UP/DN wheel on the AFCS mode controller. Monitor proper power settings to maintain
safe operating airspeed.
6. The autopilot will hold the commanded rate of descent within
±
50 feet per minute. Change the
vertical speed descent reference to 700 feet per minute. The autopilot maintains the commanded
rate of descent within
±
50 feet per minute. Allow the autopilot to capture the selected altitude.
