Flight and Nav Instruments

Question 1

Name all 6 basic flight instruments

Answer 1

• Airspeed indicator
• Altitude indicator
• Altimeter
• Turn indicator
• Heading indicator
• Vertical Speed indicator

Question 2

Which instrument indicates pitch and bank?

Answer 2

Altitude indicator

Question 3

How does the Altimeter work?

Answer 3

By measuring air pressure entering through the Pitot-Static (P-S) system

Question 4

How does the Air-speed indicator work?

Answer 4

By measuring the differences in air pressure in the P-S system

Question 5

What types of stall sensor do you know?

Answer 5

Reed

Switch

Question 6

How do stall sensors work?

Answer 6

As the stall angle is reached, the devices activate when the low pressure airflow flows over them, either making a noise, or indicating that the limit is reached

Question 7

Name a type of gyro-instrument

Answer 7

Altitude indicator
Turn indicator
Heading indicator

Question 8

What does the turn indicator show?

Answer 8

The direction and rate of turn

Question 9

What type of heading indicator do you know?

Answer 9

Directional Gyro
Ring Laser
Fibre optic
Micro Electro Mechanical Systems

Question 10

How does a magnetic compass work?

Answer 10

The needle of a compass aligns with the earths magnetic field, so it points south and north

Question 11

What is the principle of operation of pitot static system?

Answer 11

Uses the pressure gradient and using it to calculate the speed and altitude
