Divertion

Sometimes we cannot land at the airfield we had planned. We have to divert. To do this:

Calculate an estimated Heading to the diversion airfield to within 10°.
Refine the heading calculation using the protractor.
Calculate and respect a safety altitude in relation to the terrain with the ICAO chart.
Check that no special status areas are to be passed.
Calculate a first vertical estimate of the diversion area with the fingers (one finger = 5 nautical miles = 10 km on the ICAO chart).
Landmarks are taken for a diversion longer than 15 minutes.
A fuel balance is made.
Prepare for arrival at the diversion site:
- Frequencies
- Aerodrome Integration Altitude
- Airstick, QFU, altitude and turn situation
