What a wonderful day!

Saw some studies on the variation of ISA deviation over distance. We didn’t have the data, so I asked a 737NG first officer from Jet Airways for the same. He gladly obliged, and flew the sector from Chennai to Hyderabad. “4 degrees” came his message post landing.

Wow. And what was the extreme that he has seen? “ISA dev +21, inversion layers upto +35”.

And how the aircraft performs in the light of such conditions: the study was superb.
