Performance
What are the 2 control instruments?
Power instruments
Attitude indicator
What are the performance instruments?
ASI ALT VSI T&S HSI
What instruments are derived from measurement of pitot and static pressure?
Airspeed
Machmeter
How does a digital flight instrument use pitot and static pressure readings?
Pitot and Static pressure are converted using a transducer to electrical signals which are analysed by the Air Data Computer (ADC) and formatted for display.
Give the direct and indirect indications of each primary flight instruments.
Direct then Indirect ASI - Airspeed - Pitch VSI - Vertical speed - Pitch Altimeter - Altitude - Pitch HSI - Heading - Yaw or Bank Turn indicator - Rate of turn - Bank or Yaw Slip Indicator - Balance - Yaw
