At sea level, on a typical servo altimeter, the tolerance in feet from indicated must not exceed :

1) An aircraft takes off from the aerodrome of BRIOUDE (altitude 1483 ft, QFE = 963 hPa, temperature = 320C). Five minutes later, passing 5000 ft on QFE, the second altimeter set on 1013 hPa will indicate approximately:

2) Given: Pressure Altitude 29000 ft, OAT -550C. Calculate the Density Altitude.

3) Given: Airport elevation is 1000 ft. QNH is 988 hPa. What is the approximate airport pressure altitude? (Assume 1 hPa = 27 ft)

4) Given: Aircraft at FL 150 overhead an airport Elevation of airport 720 ft. QNH is 1003 hPa. OAT at FL 150-50C. What is the true altitude of the aircraft? (Assume 1 hPa = 27 ft

5) The pressure measured at the forward facing orifice of a pitot tube is the:
