How do I cancel a flight plan and re input a new one once I have filed one ?

Question

There is no option to re input the flight plan to change it. I would like to change the flight plan when I am flying.

Answer 1

If you are flying and tuned to the correct frequency, there should be an option to Cancel IFR. For example, flying out of KSEA I tuned to the control center at 124.20 and my options were Check in with controller & cancel IFR.

Otherwise I suppose you could always fly poorly enough that ATC yells at you and cancels your flight for you. ;)
