Revision 5
7. With the APR mode armed, set up a ~45
°
intercept angle using the HDG mode. When the proper
capture point is reached, the system will automatically transfer from HDG and LOC armed to LOC
mode and turn on to the inbound course. “LOC” will change to green and flash for 10 seconds to
indicate the transition to the new mode.
8. As the airplane flies into the glideslope, the system will automatically transfer from ALT to GS
mode, and the “GS” annunciation will change to green and flash for 10 seconds. The autopilot
will track the Localizer and Glideslope guidance with minimal offsets and oscillations. Continue to
the decision altitude for the ILS. Monitor proper power settings to maintain safe operating
airspeed.
9. When desired, engage the GA mode by pressing the GO AROUND button on the left throttle.
The Flight Director command bars will give a wings level pitch up command of 8
°
, and the
autopilot will disconnect. PFD1 and PFD2 will annunciate “GA” in green as both the active PIT
and ROL modes, and “ALTS” will be annunciated in white in the pitch window. Fly the command
bars and establish climb configuration to a safe altitude.
8.8.4
APR (VOR) Mode
1. With the airplane in HDG and ALT mode, tune the VOR that is used as part of a published VOR
approach. Select VOR1 on PFD1 HSI. Using published VOR approach information, set the
course selector on the HSI to the inbound course.
2. Use the HDG and ALT modes to set up 45
°
intercept of the selected VOR radial at least 5 miles
from the final approach fix. Arm the VAPP mode by pressing the APR key while the deviation is
still full scale. This will cause “VAPP” to be annunciated in white to the left of “HDG”.
3. When the proper intercept point is reached, the system will go from HDG and VAPP armed to
VAPP mode. At this point “VAPP” will change to green and flash for 10 seconds to indicate the
transition to the new mode. Verify the autopilot captures and tracks the selected course with
minimal overshoot, minimal offset and no oscillations.
4. Using any desired vertical mode (PIT, VS, or FLC), complete the published VOR approach and
note autopilot tracking of the approach course. The autopilot should track the selected course
with minimal overshoot, minimal offset and no oscillations.
8.8.5
Yaw Damper
1. With AP and YD engaged in ROL and PIT attitude hold mode and wings level, overpower
left
rudder
5-10° and release.
2. Verify the YD returns the airplane to the original attitude with no continuous oscillations or offsets.
3. Overpower
right rudder
5-10° and release.
4. Verify the YD returns the airplane to the original attitude with no continuous oscillations or offsets.
5.
Disengage the AP and YD.
6.
Perform a rudder doublet and engage the YD.
7.
Verify the YD returns the airplane to the original attitude with no continuous oscillations or offsets
8.9
TAWS ‘FIVE HUNDRED’ Call-out
1. During approach, verify that the ‘FIVE HUNDRED’ voice call-out is issued at approximately 500’
AGL (GPS altitude).
