New questions..
Thanks, great advice!
Here's another two examples I'd like to make sure I understand:
1. A/C flies at 10000'. What's the range of reception to a VOR sitting at 2000amsl?
The answer used the formula
1.225 * square of altitude
It said 1.225* square10,000 + 1.225* square 2000 = around 177NM.
What's the reason behind adding the two ranges? How do you explain this answer better?
2. Ground speed of 383Kts. DME reads 47NM from a DME station at 1500' AMSL. A/C at 30,000'. What's the EET to the station?
My main concern is the corrected range to the station which is 46.76NM in the answer I have.Is it right?
I thought I should deduct 4.7NM from 47 because at 28,500' above the station that's what the DME reads (28,500/ 6080), so range should be 42.3.
