Suppose there is a 1.1 Degrees F drop in temp. for every thousand ft. that an airplane climbs into the sky. If the temp. on the ground is 59.7 Degrees F, what will be the temp. when the plane reaches the altitude of 11,000 ft? What do I do?
+130536 The temperature at 11000 ft is given by :
59.7 - 1.1 (11) =
59.7 - 12.1 =
47.6° F
Again, Chris has it correct. As an aside: The temperature drope per 1000ft elevation gain is referred to as the 'lapse rate'. The 'standard' lapse rate is generally 3.5 degrees drop per 1000 ft altitude gain, so when your airplane is flying at 30,000 ft you can see that it is QUITE cold outside !! (approx 115 degrees colder than sea level temperature)
