(E) Air Data System Flashcards
1
Q
What are the three key parameters given to operators?
A
- Airspeed
- Altitude
- Vertical speed
2
Q
Altimeter
A
It is used to measure the altitude of an aircraft and relies on the fact the atmospheric pressure decrease with altitude
3
Q
Airspeed Indicator
A
- It registers the speed that the aircraft is travelling relative to the surrounding air
- Depends greatly on both the pitot and static pressure for its operation
4
Q
Machmeter
A
- Used to prevent structural damage or loss of control of an A/C. Unit is Mach Number
- Machmeter NOT to be used for air combat
- Speed of sound decreases with altitude
5
Q
Vertical Speed Indicator
A
Depends upon the rate of pressure change within the pitot tube
