Final Approach
Can you use it, certainly, can you rely on it with your life? That is a more difficult question to answer with a positive. What you have to take into consideration is the terrain gradient vs climb gradient. Look on the Low IFR chart and get the MEA and calculate where you can make that altitude. If you can make it to that altitude before you get to the terrain, you are safe to make the climb on the airway even if you drop the VOR at the beginning.
A little late to the party, Henning?
