Can anybody give me the right formula for approximate maximum range for VORs? I have ROOT 1.5 x height in feet. I tried a couple of sums but couldnt get the answer.
An aircraft at FL 100 should be able to receive a VOR ground station at 100 FT above MSL at an approximate maximum range of:
A) 123 NM
B) 135 NM
C) 142 NM
D) 130 NM
Either one of these is the correct answer. Dont know how though.
