SOP Monkey
Apart from the up drought itself upsetting the aircraft, that temperature rise will play havoc if you are struggling along with 1.3 G protection at say ISA. If the ambient temperature is suddenly ISA +10c (not unheard of) or ISA +05c.
In the experience that I quoted previously the OAT at FL410 went from ISA+2C to ISA+29C in the space of 5 seconds. However I would speculate that this would be less critical for an A320 at FL320, although it would put a cold aircraft surface back into the temperature region for super-cooled water droplets.
Since I don't fly the A320, any Airbus drivers got any suggestions on how an A320 would handle a sudden temp change of that magnitude at FL320?
