STBYRUD -
Clearly ice can accumulate anywhere, and if I think about how quickly ice can form on a flat, heated windscreen, then I dont want to think how fast it can collect on the tail of my 737.
I submitted a picture I took to our Safety Board for submission to the NTSB for use in the Midway accident investigation. It was a picture of our horizontal stab on a 737-200 that I took at the gate TWELVE [12] MINUTES after leaving icing conditions. There was FOUR INCHES of rime ice still on the leading edge of the stab. We took that into consideration during the approach and landed at VREF + a lot !!
Not nice to mess with Mother Nature !!
