Have you noticed the running theme of what you wrote? Signal coverage, radio coverage...
We were talking emergency. And the running theme of my post was DONT HIT TERRAIN by ALL mean available to you.
Enlighten me then. How does one get to the IAF when there is no feeder route or the IAF is not part of the low altitude system?
Yes you can take India and anywhere else in the world that has terrain as examples, but the truth is, those places adhere to the rules much better than we do in the states. The truth is, in the US, some approaches have fixes one would have a good amount of trouble navigation to using what you call "black lines" cause sometimes those black lines don't exist.
MSA Is indeed used for emergency and when you are lost comm, you are essentially just that.
You can keep on believing there is only one way and one way only to fly an airplane, I chose to open my mind and think of all possible alternatives to avoid terrain and obstacles and get on the ground safely.
