SEOPS

To use the Single-Engine Operations (SEOPS) planning option, which is only available on certain types of account, you must be flying a single-engine aircraft with the advanced data option selected and a full set of advanced performance data available.

The objective is to select suitable landing sites along the route close enough for your aircraft to glide to and safely land if the engine should fail. The gliding range at any point is calculated from the SEOPS settings of your aircraft.

1. In the SEOPS section of Step 1, select the planned departure and destination aerodromes as landing sites along your route and click Recalculate.
   The gliding ranges (from the selected flight level) are shown as blue circles on the map, with any portion of the journey outside these circles shaded in red (as shown below). The calculated time for which the aircraft will be outside the circles is displayed as the Risk period.
2. Enter further landing sites to cover the remainder of the route until the desired risk period is achieved (this will be displayed in green when it is below the threshold for your aircraft). Alternatively, consider increasing the flight level to increase the gliding range of your aircraft.
3. Click Save to retain these settings in the flight plan.
4. Click Flight Log and review the risk matrix calculation for each segment of the flight; ensure that the cumulative risk is below your operating authority's threshold before filing the flight plan.
