Flight Instruments

Question 1

ASI

Answer 1

Airspeed Indicator or Airspeed Gauge
ASI measures the pressure differential between static pressure from the static port and total pressure from the pitot tube.
The recommendation by ICAO is km/h, but knots (kn) is the most used unit. Also MPH & meters per second (m/s) are used.

Question 2

Altimeter

Answer 2

“Altitude Meter”
Instrument used to measure the altitude of an object above a fixed level. Measurement of altitude is called altimetry. The altimeter has 3 pointers, 100’, 1000’, & 10000’.
*must be inspected every 24 months.

Question 3

Transponder

Answer 3

Device for receiving radio signal and automatically transmitting a different signal.
*must be inspected every 24 calendar months.

Question 4

Pilot-static system

Answer 4

A system of pressure-sensitive instruments-

• used to determine an aircraft’s: airspeed, Mach number, altitude, and altitude trend.
• generally consists of: a pilot tube, a static port, and the pilot static instruments (altimeter, vertical speed indicator, airspeed indicator).
• must be inspected ever 24 calendar months

Question 5

Pilot-static Instruments

Answer 5

Altimeter, Vertical Speed Indicator, Airspeed Indicator.

Question 6

ELT

Answer 6

Emergency Locator Transmitter

Helps rescuers find aircraft & people in distress following an aircraft impact with terrain.
