Line of Sight Calculator with Map

This page will give you a plot of your Line-of-Sight distance to aircraft at various altitudes.

The inner most circle are aircraft up to 5,000'. Working out each circle represents aircraft at 10,000', 20,000', 30,000', and 40,000'.

Odds are you're not going to hear aircraft out to the edge of each circle, that would only happen in the "perfect" world. Factors that will reduce you're ability to hear to the edge of the "Line-of-Sight" circle are 1) Your antenna, 2) obstructions (tree, building, mountains...), 3) aircraft orientation (climbing / decending / banking all could block the transmitting antenna from your line of sight), 4) weather conditions between you and the aircraft (signals are attenuated by clouds or rain), 5) signal to noise ratio of your receiver / amps / antenna locaton.

While true line of sight distance will give you an idea of how far out you could receive aircraft, many other factors play into the fact of actually receiving aircraft that far out.
