Procedure Guide

The following section describes the typical use of the EFIS and autopilot during the different flight phases. Please note that this is only a best-practice recommendation.

PREFLIGHT

1

Set up your flightplan in the GNS-XLS

As soon as the aircraft is powered, you should first enter your flight plan into the FMC. You can either import your last SimBrief flight plan or enter the route manually.

Please note that after a SimBrief import you still need to select the SID and STAR, as only the enroute waypoints are loaded.

Once the route is set, you should check the VNAV profile. On the DATA page you can enter your cruise level, and on the VNAV WAYPOINT page you can change constraints. Especially for an RNAV approach, we recommend changing constraints from “above (A)” to the lowest altitude value. This will create more level-off phases, giving you enough time to reduce speed.

Set up your EFIS and autopilot modes

When your flight plan is fully set up, you should configure the EFIS accordingly.

✅ NAV Source to FMS

Set the autopilot navigation source to FMS so that it follows the GNS-XLS route. Cycle the COURSE button until the EHSI indicates FMS at the lower left border.

✅ Arm NAV, SPEED and ALT mode

Press the NAV button on glareshield panel to engage the flight director NAV mode so it will follow the GNS-XLS lateral route.

Press the SPEED button on glareshield panel to engage the flight director IAS hold mode. Set the speed bug on the EHSI speed tape to V2+10 KIAS for initial climb out.

Dial in your target climb altitude on the altitude selector (be aware of constraints on departure!) and press the ALT button to arm the ALT select mode.

✅ Engage Yaw Damper

Engage the yaw damper by moving up the left bar on the autopilot selector panel.

Set up ASI and Altimeter

✅ Speed Bugs

Since the EADI only has one speed bug, which we already set to V2+10, we recommend setting the speed bugs for rotate and the different flap speeds on the analog airspeed indicator. You can also do this with a single click via the TAKEOFF page on the clipboard.

✅ Acceleration Altitude

The acceleration altitude is usually 1,500 ft above the airport elevation. Set the white marker on the analog altimeter accordingly using the right knob with the corresponding indication.

TAKEOFF

1

Before Takeoff Run

Optional: Activate Elapsed Time Timer

Select the ET (elapsed time) readout on EHSI by cycling through the modes with NAV DTA button on CHP (is ET by default).

Press ET button on CHP once to start the timer.

You can change the NAV DTA mode afterwards, the timer will continue to run.

The elapsed time (aircraft airborne) is automatically being recorded on the Davtron clock so this step is optional.

2

After Liftoff

Follow the flight director pitch and bank for the initial climb out.

3

Passing 1.500ft AGL

✅ Activate CLIMB speed

On the glareshield panel click on the CLIMB button to activate the L (low) climb mode which sets the airspeed bug to 230 KIAS. Follow the flight director accordingly.

✅ Set flaps

During acceleration set the flaps according to the normal flaps schedule.

✅ Engage autopilot

Engage the autopilot by moving up the right bar on the autopilot selector panel whenever you feel comfortable.

DESCENT

During the flight monitor your TOD on the GNS-XLS VNAV 1/X page. It shows you both distance and time.

1

Approaching TOD

✅ Reset target altitude

Before reaching the top of descent reset your target altitude on the altitude selector according to your approach procedure or ATC clearance.

✅ Activate VNAV mode

Press the VNAV button on glareshield panel to activate vertical path tracking. The aircraft will initiate the descent automatically towards the target altitude. You can monitor the descent path on the GNS-XLS VNAV 1/X page.

Be aware that level off segments will be taken into account causing the aircraft to stop descending even though the target altitude of the altitude selector has not been reached yet.

2

Passing 10.000ft

✅ Set speed and decision height bugs

For approach you have to set the speed bugs on the analog ASI. They can be found in the clipboard LANDING page.

Set your decision height on the analog radio altimeter as well as on the EADI by rotating the DH/RNG knob on the Display Control Panel.

✅ Reduce airspeed

Reduce airspeed to join the final approach with flaps set to 1 or more.

3

At Initial Approach Fix

✅ Engage approach mode

For ILS approach:

• On intercept track change lateral mode to HDG or ROLL to maintain track.

• Use COURSE button to set NAV source to NAV1.

• Set ILS course with CRS1 knob.

• Arm approach mode by pressing APPR button on glareshield panel.

For RNAV approach:

• on intercept track arm approach mode by pressing APPR button on glareshield panel.

As soon as the approach is engaged (FMA is green) the selected target altitude can be changed to the go around altitude as it will be ignored by the autopilot, even if it's lower than your current altitude.

LANDING

1

Final approach

✅ Disengage autopilot

Disengage the autopilot whenever you feel comfortable by using the disconnect button on the yoke or moving down the right lever on the autopilot selector panel.

2

Go around (requires autothrottle)

✅ Activate GA mode

Press the 2 palm switches on the throttle to engage go around mode. They are only available if you have the auto throttle switch option enabled in clipboard.

The AP disengages, cancels selected lateral and vertical modes, and provides wings-level and 10 degrees pitch up commands.

✅ Reengage autopilot

Once your aircraft is stable, enable the autopilot by moving up the right lever on the autopilot selector panel. To clear the lateral/vertical go around mode simply select any other lateral/vertical mode.
