Q1. In an Air Data Computer (ADC), aeroplane altitude is calculated from:
Correct answer is – “Measurement of absolute barometric pressure from a static source on the fuselage”
Q2. An Air Data Computer (ADC) obtains altitude from:
Correct answer is – “barometric data from static source”
Q3. An Air Data Computer (ADC) :
Correct answer is – “Transforms air data measurements into electric impulses driving servo motors in instruments”
Q4. The right static vent is blocked, when the aircraft yaws to the right. What does the altimeter do?
Correct answer is – “under-read”
Q5. What errors can the Air Data Computer correct for? 1. Instrument error & ram rise 2. Compressibility & density error 3. Lag & density error 4. Position & temperature error 5. Temperature & instrument error 6. Manoeuvre error & ram rise 7. Manoeuvre & position errors
Correct answer is – “2 & 4”
Q6. From where does the air data computer (ADC) obtain aircraft altitude?
Correct answer is – “Absolute barometric sensor on aircraft fuselage”
Q7. The advantages provided by an air data computer to indicate the altitude are : 1.Position/pressure error correction 2. Hysteresis error correction 3. Remote data transmission capability 4. Capability of operating as a conventional altimeter in the event of a failure. The combination of correct statements is :
correct answer 1,2,3.
4 is wrong.
2. is also wrong.
correct is 1 and 3 only.
Q8. ### What are the inputs to the ADC? 1. OAT 2. dynamic pressure 3. TAT 4. static pressure 5. electric power 6. pitot pressure 7. AoA
Correct answer is – “3, 4, 5, 6, & 7”
Q9. The advantages of an ADC over a traditional pitot-static system (list): 1. position and compressibility correction 2. reduced lag 3. ability to supply many instruments 4. ability to act as an altimeter following failure
Correct answer is – 1,2, and 3 ( 4 is wrong – that is ability to act as an altimeter following failure )
Q10. If a large aircraft is side slipped to starboard, and the port static vent is blocked, what will the altimeter read?
Correct answer is – “Under-read”
