General Tips Auto Coupled Approach
Auto Coupled Approach
  Typical ILS approach & Landing
1 AP Altitude Lock ON when tracking outbound and around procedure turns.
2 Perform turn using 'HEADING' mode.
3 Attack ILS beam at 45 degrees then select 'GLIDE' on the autopilot.
4 Check 'ALT' mode disengages when Glide Slope is intercepted.
5 Use of 23 & 28 degree flaps is at the pilots discretion.  Approach speeds should not be below 150 kt until 45 degree flaps selected.
6 45 degree flap selected at 1500 ft (or by 3 miles to run at the latest)
Monitor ASI carefully on final approach and reduce speed to Vat + 5 kts (or Vat + 1/3 of reported windspeed if over 15 kts)
7

The approach must be monitored by reference to the CDI, ASI and by visual reference.
One hand must be kept on the control column in readiness to revert to manual control.
Unless autolanding, Auto Pilot & Throttle mode off at decision height, making sure to correct any movement when AP disengaged.

8 At threshold reduce decent rate to under 300 ft/min, then select engines idle. Hold until wheels touch.
It is normal to flare around 4-5 degrees.

If you are using auto throttle during landing, it is advisable to close your joystick/yoke throttle in FS.  If you do not do this, the throttle setting from your joystick/yoke can unexpectedly register after auto throttle is turned off.


Auto Land
When established on the glide slope, select 'Land' instead of 'Glide' on the auto pilot unit.  It is best if this is done above 1000 ft above the ground.  (Before the green 'Kick off Drift' flag shows on the Radio Altimeter)
Note :-
Auto land can only be made at an airport that is equiped to the required standard.

During an automated approach & landing the Airspeed still has to be set manually into the auto throttle control.


At around 1000ft (above ground), Auto Land activates a more accurate approach phase than is normal for an ILS in FS.
Hopefully, this will guarantee the aircraft landing on the runway, even in a cross wind that would normally have FS missing the runway completely!
It will work best if the speed is held at Vat from 1000ft (above ground) onward.
At the correct moment, Auto land cuts the throttle, performs a flare and uses the rudder to help kick off any drift to land as straight as possible on the runway.  (Note: If you run FS with the autorudder option selected, this will not happen)
The Trident's auto rudder can be switched off by clicking the blue 'Rudder' light on the glare shield.

During this last phase of an auto land, the green 'progress' lights flash to indicate that the system is working correctly.
Auto spoiler & lift dumpers will activate on touchdown.
