Mountain Flying
Comprehensive Mountain Flying Course
Ground School + Flight Training
Flying in the mountains is one of the most beautiful experiences for a pilot—it also can be the most dangerous. Join us for a private mountain flying course and learn the tips and tricks to safe mountain navigation.
Mountain Flying
Tip #1
Don't Be Dense on Density Altitude
All aircraft (even jets) lose 3% of power with every 1000' of elevation gained. A normally aspirated (NA) piston aircraft struggles to climb at altitudes above 15,000'. The Telluride airport, on an 80°F day, can have a DA of 18,000 or higher! When it comes to high and hot, there are few piston airplanes on the planet that would be able to
depart in these conditions.
​
When flying in the summer, start EARLY when temperatures are at their coolest. This will give you propeller, engine and wing the densest air possible.

Tip #2
Air Makes Waves
Mountain Wave can extend as high at 60,000' and as far as 250 miles from the mountain range it first encounters. When the ridgelines are experiencing >30kt winds, expect significant mountain wave. Mountain wave can result in updrafts AND downdrafts of 6000fpm!
​
Often, mountain wave will be visible based on the type and position of clouds. A standing lenticular cloud (found at the top of the wave) and rotor clouds (found below the lowest layer of wave) can let you know where (or when not to) fly.

Tip #3
Have An Escape Plan
Approach a ridgeline at a 45° angle—this will give you the ability to make a turn away from a downdraft. When the winds are >20kts, traverse the ridgeline at an altitude 3000' AGL to give you plenty of height above terrain in case of a strong downdraft.
​
Updrafts can help you gain altitude before crossing a ridge. They are ALWAYS found on the windward side of the ridge.
​
Avoid being low on the leeward side—this is where you'll find the most significant down drafts and rotor clouds (these clouds are associated with severe turbulence).
