Study Notes
Flight Instruments
- The 6-pack flight instruments are the initial set student pilots learn.
- These instruments include: Airspeed Indicator (ASI), Altimeter, Attitude Indicator (AI), Heading Indicator (HI), Turn Coordinator (TC), and Vertical Speed Indicator (VSI).
Pitot-static Instruments
- Pitot-static instruments derive data from relative air pressure.
- These instruments extrapolate metrics like altitude and speed.
- Included instruments are the Altimeter, Vertical Speed Indicator, and Airspeed Indicator.
Altimeter
- Indicates aircraft altitude relative to current atmospheric pressure.
- Pressure changes at different altitudes affect altimeter readings.
- Altimeters need calibration using weather forecasts at stations located 100 nautical miles within the flight path, especially in areas with rapidly changing atmospheric pressure.
Vertical Speed Indicator (VSI)
- Measures the rate of ascent or descent of the aircraft.
- The VSI compares the airflow rate through a metered hole to the ambient outside pressure.
Airspeed Indicator (ASI)
- Measures the aircraft's speed, providing readings in knots (nautical miles per hour).
- The ASI uses pressure at the pitot tube, which is generated by the aircraft's forward motion through the air.
Gyroscopic Instruments
- Utilize spinning gyroscopes and gimbals to track aircraft attitude and headings.
- Gyroscopic instruments aid in maintaining pilot orientation.
- Common gyroscopic instruments include: Turn Coordinator, Attitude Indicator, and Heading Indicator.
Turn Coordinator
- Shows if the aircraft is slipping or skidding during turns.
- The black circle's position relative to the instrument's frame indicates the need for rudder adjustments for coordinated turns.
Attitude Indicator
- Displays the aircraft's attitude (pitch and roll) relative to the horizon.
- The instrument shows a blue area for the sky and a brown area for the ground.
- Movements of the aircraft related to pitch and roll are reflected in the positions of the brown and blue sections.
Heading Indicator
- Acts as a compass, graphically indicating the aircraft's heading (direction).
- The aircraft graphic on the instrument shows the current direction of travel.
Primary Flight Display (PFD)
- A consolidated display that combines the functions of several traditional flight instruments.
- Modern aircraft use PFDs to provide pilots with a concise representation of aircraft data.
