Study Notes
Flight Instrumentation
- Pilots utilize features like the CROSSHATCH FLAG/10,000 FLAG to quickly recognize altitudes in thousands and hundreds of feet.
- Pitot Tube Heaters prevent icing by heating the pitot tube, ensuring accurate airspeed readings.
- The BAFFLED PLATE protects the pitot tube from moisture and dirt intrusion, ensuring measurement accuracy.
Pitot Static System
- Three instruments relying on the Pitot Static System include the Altimeter, Vertical Speed Indicator (VSI), and Airspeed Indicator.
- The Pitot Static System gathers and distributes air pressure data necessary for flight instrumentation.
Remote Sensing
- The Remote Sensing Instrument System collects data from extensive, often inaccessible areas.
Wright Flyer Instruments
- The Wright Brothers utilized the Engine Tachometer, Anemometer, and Stopwatch on their Wright Flyer for various flight measurements.
Vertical Speed Indicator Characteristics
- The VSI experiences a lag error during rapid climbs or descents, typically between 1 to 4 seconds.
Altimeter Functions
- The triangular needle on the Altimeter indicates tens of thousands of feet.
- It gauges the vertical distance from mean sea level to a ground point, known as elevation.
Airspeed Indicator Mechanics
- To calculate dynamic pressure, static pressure is subtracted from total pressure in the airspeed indicator system.
- The Airspeed Indicator has a density error; lower air density results in a lower Indicated Airspeed (IAS).
Aircraft Dynamics
- A headwind acts to push the aircraft, affecting its speed and control.
- The Vertical Speed Indicator (VSI) measures altitude changes and requires data from the static port for accurate readings.
Altimeter Types
- A Radio/Radar Altimeter sends a signal toward the ground and measures the bounce-back time to determine altitude.
Aircraft Instrument Systems
- Aircraft Instruments provide essential information on status and performance during flight.
- Backup components are included in the Pitot Static System to ensure static pressure availability if the primary static source becomes blocked.
