a) Equal to SAT (Static Air Temperature)
b) Equal to SAT (Static Air Temperature) + RAM rise.
c) Less than SAT (Static Air Temperature)
d) None of above
Q5. What kind of thermometers is used if we want to measure really high temperatures?
a) A thermistor thermometer
b) Direct Reading Thermometer
c) Optical Pyrometers
Q6. About Pitot-Static System
The pitot-tube must has a drain hole
The pitot-tube must has a system that prevent ice formation
In large aircraft is a system that used to be redundant
All of above are correct.
Q7. What is the main reason of having multiples holes in static ports in aircrafts?
a) Because it is cool
b) In order to ensure the right measurement at different aircraft attitudes
c) To do it a redundant system.
d) B and C are correct.
Q8. What is the main characteristic of thermocouples thermometers?
Temperature is calculated by the average of two measurements.
In order to do the measurement is needed a reference temperature that never changes.
It is built by two direct reading thermometers
All of above are correct
Q1. Which is one disadvantages of the Thermistor:
Low precission resistance
Need electrical source
Measurement at large distance
Thin temperature range chaning sensor resistance
Q2. Which is the function of the Drain Hole, in Pitot-Static System:
Allows any moisture to leak away without affecting sensing pressure
Prevent ice formation
To ensure right measurement at different aircraft attitudes (minimize position error)
Redundancy of the system
Q3. Pitot-Static System gives measurement of:
A. Static pressure.
B. Total pressure due to the aircraft motion
C. A and B.
D. Pressure inside the cockpit.
Q4. Which is not a Pitot-Static error:
A. Static ports place (position error)
B. Blockage of ports and lines
C. Rupture of lines
D. A, B and C are true
Q5. Which is not a problem of the capsules:
Hysteresis
Material aging
Expensive
Temperature error
Q6. Which is true, in relation with servo altimeters:
The mechanical movement of the capsule is transmitted mechanically
It moves a bar (I-bar) that modifies an electrical signal sent to an electrical motor.
Feedback system must recover the final position of the bars
The solenoid is attached to the I-bar
