FAQs

1. How do I calculate true airspeed?
   • True Airspeed (TAS) can be calculated using the indicated airspeed (IAS), pressure altitude, and temperature. A simplified formula is TAS = IAS + (IAS * (pressure altitude / 1,000) * 2%). For precise calculations, use flight computers or online calculators.
2. What is the formula for calculating TAS?
   • The formula to calculate True Airspeed (TAS) is TAS = IAS + (IAS * (pressure altitude / 1,000) * 2%). This formula provides a simplified approximation; more accurate calculations consider additional factors.
3. How do you find TAS from CAS?
   • To find True Airspeed (TAS) from Calibrated Airspeed (CAS), you need to adjust for altitude and temperature. You can use the TAS = IAS + (IAS * (pressure altitude / 1,000) * 2%) formula to estimate TAS based on CAS, altitude, and temperature.
4. What is the rule of thumb for TAS?
   • A general rule of thumb is that TAS increases by approximately 2% for every 1,000 feet increase in altitude.
5. How do you calculate true airspeed flight planning?
   • For flight planning, you would use more accurate TAS calculations that consider altitude, temperature, and variations in air density. Flight computers or aviation software can provide precise TAS values for planning.
6. What is the formula for TAS and IAS?
   • The formula for calculating True Airspeed (TAS) from Indicated Airspeed (IAS) is TAS = IAS + (IAS * (pressure altitude / 1,000) * 2%). This formula provides an estimate based on altitude.
7. What is the formula for TAS and ground speed?
   • Ground Speed (GS) is different from TAS and is calculated by considering the aircraft’s TAS and the effect of wind. There’s no direct formula relating TAS and GS.
8. What is a standard rate turn TAS?
   • A standard rate turn is typically performed at a bank angle of 15 degrees per second, and the TAS for such a turn depends on the aircraft’s IAS, altitude, and specific aircraft characteristics.
9. What is the TAS of the airspeed indicator?
   • The Airspeed Indicator displays Calibrated Airspeed (CAS), not True Airspeed (TAS). TAS calculations require additional factors, including altitude and temperature.
10. Is CAS the same as TAS?
    • No, Calibrated Airspeed (CAS) is not the same as True Airspeed (TAS). CAS is the airspeed measured by the airspeed indicator, while TAS is adjusted for altitude and temperature to account for variations in air density.
11. How do you use a TAS airspeed indicator?
    • The airspeed indicator primarily displays Calibrated Airspeed (CAS), but it may have a TAS ring that can be set based on altitude and outside temperature. Pilots use this ring to approximate TAS after setting the appropriate values.
12. What is the difference between calibrated and true airspeed?
    • Calibrated Airspeed (CAS) is the airspeed indicated by the aircraft’s airspeed indicator. True Airspeed (TAS) is CAS adjusted for altitude and temperature variations to provide the actual speed through the air.
13. Does TAS change with altitude?
    • Yes, True Airspeed (TAS) changes with altitude. As you climb to higher altitudes, TAS generally increases due to lower air density.
14. What variation in TAS should be reported to ATC?
    • Significant variations in TAS due to altitude changes should be reported to ATC to ensure accurate tracking and separation of aircraft.
15. What is the formula for radius of turn with TAS?

16. How do pilots use true airspeed?
    • Pilots use True Airspeed (TAS) for various flight planning and performance calculations, including fuel consumption, navigation, and determining aircraft performance limits.
17. What is the difference between TAS and IAS?
    • The main difference between True Airspeed (TAS) and Indicated Airspeed (IAS) is that TAS accounts for altitude and temperature effects, providing the true speed of the aircraft through the air.
18. What is the true airspeed of a Boeing 747?
    • The True Airspeed (TAS) of a Boeing 747 varies depending on factors such as altitude and weight. It can range from approximately 500 to 600 knots or more.
19. Why use IAS instead of TAS?
    • Indicated Airspeed (IAS) is used for various flight operations because it provides immediate information about aircraft performance, while True Airspeed (TAS) requires calculations to account for altitude and temperature effects.
20. How to convert TAS to IAS?
    • The conversion from True Airspeed (TAS) to Indicated Airspeed (IAS) involves adjusting for altitude and temperature. It is typically performed using charts or flight computers. There’s no simple formula for this conversion.
21. Can IAS be greater than TAS?
    • No, Indicated Airspeed (IAS) is always lower than True Airspeed (TAS). TAS accounts for altitude and temperature, which typically result in a higher airspeed reading.
22. Is true airspeed the same as ground speed?
    • No, True Airspeed (TAS) is the actual speed of the aircraft through the air, while Ground Speed (GS) is TAS adjusted for wind speed and direction, representing the aircraft’s speed relative to the ground.
23. What is a standard 2 minute turn?
    • A standard 2-minute turn is a turn performed at a constant rate, completing a 360-degree turn in 2 minutes. It is used in aviation for standard rate turns.
24. How do you find TAS in aviation?
