"1. What is the theoretical maximum range that an aircraft at FL420 will obtain from a VOR beacon situated at 400' amsl?
ans - 276nm

2. What is the approximate maximum range that an aircraft flying at 25000' would expect to obtain from a VOR beacon situated 900' amsl?
ans - 198nm"

Max Theoretical Range of Vor = 1.23 √Receiver Ht (in feet) + 1.23√Transmitter Ht (in feet)

= 1.23 √42000 +1.23 √400
= 276 nm

Approximate Maximum Range = 1.23√[Reciever Ht + Transmitter Ht(in feet)]


= 1.23√[25000+ 900]
=198 nm
