Mayday Fuel Assumptions
The documentation indicates that Mayday Fuel is declared when you expect to land below final reserve. Sounds simple enough, but is this based on the assumption you will get a direct to final after the Mayday is declared? Or does it include a routing with more track miles such as a star? You could end up declaring a Mayday on the basis of flying an entire star only to be given a direct to final and end up landing significantly above final reserve. What would be the consequences of this?
