6.5 EXAMPLE PROCEDURES

NOTE:Thediagramsinthissectionareforinstructional purposes only and should not be used for navigation.

Thissectionprovidesascenario-basedsetofprocedures showing various GFC 700 AFCS modes used during a flight. In this scenario, the aircraft departs Reid-Hillview Airport (KRHV) from runway 13L, enroute to Fresno Yosemite International Airport (KFAT). Per the filed flight plan, the aircraft climbs to an altitude of 7000 feet MSL at a heading of 070° to intercept airway V107.

Airway V107 is flown to Panoche VORTAC (PXN) using VOR navigation, then airway V230 is flown using a GPS flight plan. On this leg, the aircraft descends to 3000 feet prior to reaching Clovis VORTAC (CZQ) and the ILS approach to R29R at KFAT is loaded. The ILS approach is flown and a missed approach is executed.

070

Climbing to the Selected Altitude and flying an assigned heading:

1)Upon takeoff, set the Selected Altitude to 7000 feet using the ALT Knob.

To have the autopilot capture this altitude, use Pitch Hold,Vertical Speed,or Flight Level Change Mode. In this example, Vertical Speed Mode is used.

2)Upon reaching the desired vertical speed of 1000 fpm, enable the flight director in Vertical Speed Mode.

a)Press the VS Key to activate Vertical Speed Mode and arm Selected Altitude Capture Mode.

KFAT

TheVertical Speed Reference may be adjusted after Vertical Speed Mode is selected using the NOSE UP/NOSE DN keys or pushing the CWS Button while hand-flying the aircraft to establish a new Vertical Speed Reference.

b)Press the AP Key to engage the autopilot in Roll Hold and Vertical Speed modes

4)As the aircraft nears the Selected Altitude, the flight director transitions to Selected Altitude Capture Mode, indicated by the green ‘ALTS’ annunciation flashing for up to ten seconds.

At 50 ft from the SelectedAltitude,the green‘ALT’ annunciation flashes for up to ten seconds; the autopilot transitions to Altitude Hold Mode and levels the aircraft.

FLIGHT CONTROL

Intercepting a VOR

During climb-out, the autopilot continues to fly the aircraft in Heading Select Mode. Airway V107 to Panoche VORTAC (PXN) should now be intercepted.

Intercepting a VOR:

1)Tune theVOR frequency and activate Navigation Mode.

a)Use the CDI Softkey to set the navigation source to VOR.

b)Use the CRS Knob to set the Selected Course to 116°. Note that at this point, the flight director is still in Heading Select Mode and the autopilot continues to fly 070°.

c)Press the NAV Key to arm Navigation Mode. The white annunciation ‘VOR’ appears as the armed roll mode.

2)When the CDI shows less than one dot, the flight director changes from Heading Select to Navigation Mode, and the green annunciation ‘VOR’ flashes. The autopilot begins turning to intercept the Selected Course.

3)The autopilot continues the turn until the aircraft is established on the Selected Course.

Flying a Flight Plan/GPS Course

NOTE: Changing the navigation source cancels the flight director’s Navigation Mode and causes the flight director to automatically revert to Roll Hold Mode, wings level.

As the aircraft closes on PanocheVORTAC,a GPS flight plan is entered for the next leg, airway V230. To do this,PXN,CZQ,and KFAT are entered into the active flight plan.

The aircraft is currently tracking inbound on the 116° radial of Panoche VORTAC.

Flying a GPS flight plan:

1)Enter PanocheVORTAC (PXN) and ClovisVORTAC (CZQ) into the GPS flight plan, in preparation to intercept this leg.

2)Transition from VOR to GPS Navigation Mode.

SECTION 6 – AUTOMATIC

FLIGHT CONTROL

a)Use the CDI Softkey to select GPS as the navigation source. This causes the flight director to lose the VOR signal, and the VOR annunciation flashes yellow as the autopilot rolls the wings level.

Flashes 10 sec, Transitions to Roll Hold Mode

Unless NAV Key is Pressed

b)Press the NAV Key to activate GPS Navigation Mode and cause the autopilot to steer the aircraft toward the active flight plan leg.

If the NAV Key is not pressed within ten seconds of the VOR signal loss, the flight director reverts to Roll Hold Mode

3)Once the leg is intercepted, the autopilot continues to track GPS guidance to the end of the flight plan.
