It’s just a quick mental-calculation technique used during flight — since a pilot obviously can’t just stop the aircraft and grab a calculator like in a simulator or at home.

What it really means is that for every foot of altitude gained, you’ll use about 6 meters more of runway. That’s because most runway lengths around the world are measured in meters.

But if you’re flying in the U.S., you could use 1:20 instead.( 1foot height for 20 feet length )

Or if you really want to be exact, you could say 1:19.68 (from 6 meters convert to feet) or more accuracy 1:19.0838 (3 degree angle)

Are you a pilot, or a math teacher?I think a pilot would understand exactly what I’m talking about.
