General Tips Auto Coupled Approach
Take off
  • The elevator trim setting is important for takeoff.  The model needs around 2.5 degrees nose up trim on takeoff. If you do not set the nose up trim, it will not rotate at the correct Vr speed.
    The cockpit 'check list' gauge can be used to check if elevator trim is set within acceptable limits.

  • Click the top half of one of the Thrust Index gauges to automatically set the correct index number before a take off.  Correct take off power is with Thrust Index reading 100%.

  • Flaps should normally be set at 10 degrees. 16 or 23 can be used for a shorter run.

  • Click the 'Speed Reference Chinagraph' on the left of the main panel to get the correct rotate speed (Vr) for the aircraft's current weight & flap configuration.

  • The 'check list' toggle button gives the essential settings needed for a takeoff.  Each setting is shown with a tick or a cross, making it easy to quickly check if your configuration is correct.

  • If the Trident 3 booster is being used, switch it to 'Climb' power.
    The booster is only needed if the take off run is short & weight is high.  A 2500 metre run is plenty at any weight & the booster would not be needed.  The booster will very rougly cut around 200 metres off the takeoff run.

  • Initial climb out should be at least V2+20, flaps up at 2000 ft.  Acceleration can be rather slow when heavy.

  • Slats up at 225 kt.  If heavy, you may need to reduce your climb rate to reach 225 kt.
  • The Trident 3 booster engine will cut off automatically at 250 kt, but you should press the booster Stop button before this happens.

  • Normal speed for the climb is 290 kts.   Use a lower speed if a greater rate of climb is needed.

  • Climb power is 93% RPM, up to 95% if needed.

  • IAS hold can be selected at the desired speed, leaving the autopilot to adjust your climb rate.  Or use Height Aquire mode & adjust the climb rate using the auto pilot's pitch wheel.

  • If climbing to high altitudes (over 30,000ft) using IAS hold, switch over to Mach Hold instead if a Mach number of 0.82 is reached.

  • With IAS or Mach hold, Height Aquire mode can be used to automatically flare onto a pre-selected cruise altitude.  Power must be reduced manually when the pre-set altitude is reached.
  • Normal cruise altitudes range from 25,000 ft to 36,000 ft.

  • Normal cruise speed is Mach 0.84 - 0.86
    Mach 0.886 is the maximum cruise speed.

  • Use Height Lock and adjust power manually to keep a steady cruising Mach.
  • The flaps do not cause much nose down attitude.  However some nose up trim will be needed to compensate for loss of speed.  It is normal for the model to need around 5 degrees of nose up trim with full flaps selected.

  • Be aware of the maximum landing weights & their speeds.  While the aircraft can land safely at full weight, over weight landings were only done in an emergency.
    Normal landing weights will give Vat speeds of between 123 & 137 kts.

  • Click the 'Speed Reference Chinagraph' on the left of the main panel to get the correct landing speed (Vat) for the aircraft's current weight.

  • To perform an autoland follow normal automated ILS approach, but select 'Land' mode on the auto pilot unit once established on the glide slope.
    Auto land can only be made at an airport that is equiped to the required standard.  Note - some airports use an 'off centre' ILS beam & this is not suitable for auto land.

  • When flying at the correct speed on the glide slope, the Trident should be slightly nose up.

  • As a rough guide, 45 degree flaps should have been selected by 3 miles to run.

  • During an autoland the Trident's auto rudder will attempt to correct any drift (kick off drift) just before touchdown. If you run FS with the autorudder option selected, this will not happen.
    Auto rudder can be cancelled by clicking the blue 'Rudder' light on the front of the glareshield.

  • At the point of touchdown, the model's rudder is always under manual control only.  If any drift correction was performed during an autoland the rudder is intentionally not centred with some deflection remaining on to counter the assumed cross wind.

  • Select reverse thrust when all wheels are down, reverse off at 80 kts.  Brakes as required.  Some differential braking may be needed to keep the aircraft straight in a cross wind.
