Quick way to determine holding time for fuel?
Maybe i'm thinking too hard but what's a sure fire way to figure out the longest time you can be holding for? In terms of jets with an FMS
I've never gotten into a situation where I've told atc "we have XXX minutes to hold or else".
My thought is take the fuel left at destination, plugging it into the box and seeing how close that brings me to minimum fuel at destination and take the difference and use math by the fuel flow.
