An online TAS Calculator to calculate true airspeed which is also called as Knots True Airspeed (KTAS) of an aircraft. It is the speed of the aircraft relative to the air mass in which it is flying. True Airspeed Calculator is designed to give a correct value of true air speed based on the speed estimation flying at the planned true airspeed. Enter the values for Indicated airspeed, Mean Sea level altitude and Outside Air Temperature to get TAS.
Conversions Table; 1 Knots to Mach Number = 0.0015: 70 Knots to Mach Number = 0.1058: 2 Knots to Mach Number = 0.003: 80 Knots to Mach Number = 0.1209. The calories burned calculator calculates an estimate of the number of calories burned for a wide range of activities. Enter your weight and the duration of exercise, click the calculate button and the calculator will calculate the calories burned. The calculations are based on the activities Metabolic Equivalent (MET).
Indicated airspeed (IAS) is the airspeed read directly from the airspeed indicator (ASI) on an aircraft, driven by the pitot-static system. It uses the difference between total pressure and static pressure, provided by the system, to either mechanically or electronically measure dynamic pressure.The dynamic pressure includes terms for both density and airspeed.

An online TAS Calculator to calculate true airspeed which is also called as Knots True Airspeed (KTAS) of an aircraft. It is the speed of the aircraft relative to the air mass in which it is flying. True Airspeed Calculator is designed to give a correct value of true air speed based on the speed estimation flying at the planned true airspeed. Enter the values for Indicated airspeed, Mean Sea level altitude and Outside Air Temperature to get TAS.
Formula:
TAS = (IAS x OAT Estimation Correction) x (A / 1000) + IASWhere,IAS = Indicated AirspeedA = Mean Sea Level (MSL) Altitude TAS = True AirspeedExample:
An Airplane files with an Indicated airspeed of 170 and OAT Estimation Correction of 0.2 Mean Sea Level Altitude is 8500.
Solution:
TAS = (IAS x OAT Estimation Correction) x (A / 1000) + IAS
= (170 x 0.2) x (8500 / 1000) + 170
= 459

QNH refers to the altimeter setting so that an aircraft's altitude above MSL (Mean Sea Level) is indicated. This setting is used during departure and approach and requires the pilot to set the local pressure at MSL. It is provided in the ATIS information and by ATC.
The Crossosver Altitude is the altitude at which a specified CAS and Mach value represent the same TAS value. The curves for constant CAS and constant Mach intersect at this point. Above this altitude the Mach number is used to reference speeds.
The following calculations are based on the International Standard Atmosphere (ISA) & U.S. Standard Atmosphere of 1976. The current implementation will only give correct results for altitudes up to 32,000 [m] - i.e. Troposphere (Layer 0)/Tropopause (Layer 1) and Lower Stratosphere (Layer 2).
This will calculate the altitude at which the specified pressure can be found. It is the inverse calculation of the above International Standard Atmosphere (ISA) & U.S. Standard Atmosphere of 1976 pressure calculation and is subject to the same limitation of 32,000 [m].
The following will calculate three speeds based on the altitude and entered fourth speed - e.g. CAS/Mach/EAS based on Altitude and TAS. These calculations are based on the International Standard Atmosphere (ISA) & U.S. Standard Atmosphere of 1976 and are subject to the same 32,000 [m] limitation. They are also resticted to only subsonic speeds. The calculation is performed by pressing the button below the entered speed - e.g. TAS.
