When on ground, asking Jester to input new HOME BASE coordinates (from map or LAT/LON, doesn't matter) will update your current aircraft position coordinates.
So lets say I am on a carrier before transition flight to a new aerodrome and want Jester to make our destination as our new base in nav system will change our current position.
This obviously not happens when airborne.
Actualy, I found it's usefull to have an option to update our INS, but maybe there's should be more straightforward method, like a dedicated command in a Jester menu?
Thank you.
