Title: Take-off not authorized because it is too cold?
Post by: tyda0501 on October 05, 2014, 07:27:36 PM
I recently tried getting taking-off numbers for Minneapolis with the weather loaded from January 6th, 2014 in active sky which was the coldest day in over a decade there.  So with -28 degrees I get "Take-off not authorized ((UNKN) LIMITED). I actually tried warming it up to -20 and got the same thing. Any Ideas?

Air Canada cant operate here in Whitehorse when it is below -30c, air north on the other end can ... different aircraft and sleeping or not in an hangar will make the difference.

I have similar issue with TopCat
It shows the same message when temperature is M03 :(

see attachments.

I have investigated that TopCat cannot calculate anything if temperature below zero or equals.

I'm sure it's a bug :(
