rumline, yes, that is what I am getting at.
I appreciate it varies from type to type, but are there any quantifiable indications as to how long this might take?
I ask as I would appreciate the experience of other pilots how to treat this type of situation, when overflying an area of hostile terrain, either unsuitable to land, or remote from help (in my case more likely to be over urbanized, mountainous, forested or desert area, rather than the ocean).
Naturally a bias would lean towards Land Immediately, unless otherwise indicated in the relevant type POH, and of course, prevention of getting into this state in the first place, assuming I had influence over the contributing factors.
