1) An aircraft with pressurized cabin has maximum cabin altitude of 8000 feet, which equals 10.9 psi Present flight altitude is 30000 feet, which equals 4.36 psi. Pressure at sea level equals 14.7 psi. Calculate the difference pressure that influence the cabin structure:
2) A pneumatic deice system should be operated:
3) A "Bourdon Tube" is used in:
4) Different pressure sensors are used according to the intensity of the pressure measured (low, medium or high)Classify the following sensors by order of increasing pressure for which they are suitable:1. bellows type2. Bourdon tube type3. aneroid capsule type
5) The "Bourdon tube" is used to measure:
