Calculate mintra level

[MHN_pilot]

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:ok:

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.

Thanks! :ok:

Met Office tephigrams used to have a MINTRA line printed on them. Sadly I don't think they print the old school ones anymore.

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.
