Question

As a pilot is flying in level flight at 9,500 ft, the altimeter in the instrument panel is set to a pressure of 29.48 mm of Hg. As the aircraft travels along its route, the outside air temperature changes from 23.0°C to 9.0° C. To what pressure does the pilot need to reset the altimeter in order for the altimeter to indicate the aircraft's true altitude?​

Answer 1

from the ideal gas law, P2 /P1 = T2 /T1 for the same volume and quantity of gas. P2 = (758 mmHg) (45 +273 K) / (15 +273K) = 837 mmHg.
