5 Problem 3.2 Consider an airplane flying at some real altitude. The outside pressure and temperature are p = 2.65 x 10 N/m and T = 220 K, respectively. What are the pressure and density altitudes? Problem 3.3 During a flight test of a new airplane, the pilot radios to the ground that she is in level flight at a standard altitude of 35,000 ft. What is the ambient air pressure far ahead of the airplane? Problem 3.4 Consider an airplane flying at a pressure altitude of 33,500 ft and a density altitude of 32,000 ft. Calculate the outside air temperature. Problem 3.6 Using Toussaint's formula, calculate the pressure at a geopotential altitude of 5 km.
