Calculate mintra level
Hi guys
I was just wondering if there is any way of calculating the FL at which condensation occurs, I know from some documentaries that these calculations where very important for wwII bombers and i feel curious about it.
Thanks in advance

Divide the dewpoint spread by 2. The "2" in the equation is the lapse rate in centigrade. Temp is 24C, dewpoint 18C, the spread is 6C, divide by 2 equals a cloud base at 3000 feet.

That's a bit simple, galaxy flyer - and doesn't answer the question.
The level at which contrails will appear was probably calculated graphically from upper air data.

Touche, Checkboard, I reread the question. I don't know how to read it, but a skew-T chart has a "kink" in the sounding that indicates the contrail level. It is used by the tactical types to avoid leaving a contrail.
