Study Notes
Basic Aircraft Instruments
- Six basic aircraft instruments include: Airspeed Indicator, Attitude Indicator, Altimeter, Turn and Slip Coordinator, Heading Indicator, and Vertical Speed Indicator.
Pitot Static Instruments
- Pitot static instruments are vital for measuring airspeed, altitude, and vertical speed using air pressure differences.
- Includes: Airspeed Indicator, Altimeter, and Vertical Speed Indicator.
Components of Pitot Static System
- Pitot Tube: Measures ram air pressure.
- Static Port: Measures static air pressure.
Airspeed Indicator
- Primary instrument using both pitot and static pressures to display airspeed.
- Displays color-coded arcs representing different speed ranges, known as V-speeds, crucial for various flight phases.
Airspeed Color Arcs
- Green Arc: Normal operating range for consistent flying.
- White Arc: Flaps operating range; lower limit is full flap stall speed and upper limit is maximum flap speed.
- Yellow Arc: Caution range for careful flying in smooth air conditions only.
V-Speeds
- VLO: Maximum speed for raising/lowering landing gear.
- VNE: Never Exceed Speed; operations above this risk aircraft damage.
- VNO: Maximum Structural Cruising Speed; adhere to smooth air conditions below this.
- VFE: Maximum Flaps Extended Speed; do not exceed this with flaps extended.
- VSO: Stalling speed in landing configuration; critical for operations during landing.
- VS1: Minimum flight speed in specified configuration; important for performance assessments.
Types of Airspeed
- Indicated Airspeed (IAS): Read directly from the Airspeed Indicator; reflects airspeed under standard conditions but uncorrected for altitude or instrument errors.
- Calibrated Airspeed (CAS): IAS corrected for installation and instrument errors; use Pilot Operating Handbook (POH) for accurate ascertainment.
- True Airspeed (TAS): Real airspeed through the air; corrected for altitude and temperature variations.
- Ground Speed (GS): Actual speed of the aircraft over ground; adjusts for wind conditions (decreases with headwind, increases with tailwind).
Maneuvering Speed
- Maneuvering Speed (Va): Maximum speed for safe abrupt control movements without risking structural damage; crucial during turbulence.
- Max Landing Gear Extended Speed (VLE): Specific to aircraft with retractable gear during extension operations.
