  • Speed will decay and when airspeed drops below 100kts press CTRL+Q+W to switch off both engines.
  • Select outside view from stern (F6 then 5 on the numeric keypad) and turn up the volume.
  • The aircraft will stall and nose down.
  • Hold down Tab till throttles are fully closed and listen to the engine sounds.
  • Manipulate the aircraft controls to achieve full control loss and observe aircraft gyrations from cockpit and outside views.
  • To recover, ensure airbrakes and flaps are in and undercarriage is retracted.
  • Push down nose to increase airspeed and control rotation with ailerons.
  • As airspeed increases, turbine RPM will increase and be displayed on the RPM Gauge.
  • When RPM readings reach 20 or more, press CTRL+1 to relight No1 engine and CTRL+2 to relight No2.
  • If unsuccessful, reselect.
  • When relit, open throttles to about 80% and ease back to regain level flight.
  • Adjust throttles as required and continue with sortie.
  • The Artificial Horizon will have toppled and the Navigation Display will be indicating false headings.
  • The Standby Artificial Horizon may be used till the main instrument recovers.
  • Similarly, the Standby Compass may be used till the Navigation Display recovers.
