5. A pilot notices that the barometric pressure outside his aircraft is 85 kPaa. The airport below the plane
reports a barometric pressure of 100 kPaa. If the average air density is 1.15 kg m /m 3 and the local gravity
is 9.75 m/s 2 , determine the height of the aircraft above the ground in meters.
pressure altitude = (standard pressure - your current pressure setting) x 1,000 + field elevation
pressure altitude "= (100-85)\\times1000+5000 =20000" ft =6096m
