This is what we do and seems to be the general consensus in many recent articles. We teach the use of the terms in the same manner, in that you say the word three times before going ahead with the traffic. "Urgent, Urgent, Urgent, we have a live power line down on side 2."Unless I am wrong, the nationally accepted standard is urgent for anything not immediately threatening life and Mayday is for when you are in trouble.
ex. "urgent" there is an outside wall bulging on the Charlie side
ex. "mayday" I am lost and very low on air, unk where I am
Liek the prior post, why change it?
