True Aircraft Speed (Mach number) Solution

STEP 0: Pre-Calculation Summary

Formula Used

True Aircraft Speed = Speed of Sound*True Mach Number
V_TAS = c*M_True
This formula uses 3 Variables

Variables Used

True Aircraft Speed - (Measured in Meter per Hour) - True Aircraft Speed of an aircraft is the speed of the aircraft relative to the air mass through which it is flying.
Speed of Sound - (Measured in Meter per Hour) - Speed of Sound in the air is considered here and is denoted by c symbol.
True Mach Number - True Mach Number of the aircraft. Mach number is a function of temperature and true airspeed. Aircraft flight instruments operate using pressure differential to compute Mach number, not temperature.

STEP 1: Convert Input(s) to Base Unit

Speed of Sound: 47.5 Kilometer per Hour --> 47500 Meter per Hour (Check conversion here)
True Mach Number: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_TAS = c*M_True --> 47500*4

Evaluating ... ...

V_TAS = 190000

STEP 3: Convert Result to Output's Unit

52.7777777777778 Meter per Second -->190 Kilometer per Hour (Check conversion here)

FINAL ANSWER

190 Kilometer per Hour <-- True Aircraft Speed

(Calculation completed in 00.020 seconds)

Operating Empty Weight when Desired Take-off Weight is considered

LaTeX Go Operating Empty Weight = Desired Takeoff Weight of Aircraft-Payload Carried-Fuel Weight to be carried

Payload carried when desired take-off weight is considered

LaTeX Go Payload Carried = Desired Takeoff Weight of Aircraft-Operating Empty Weight-Fuel Weight to be carried

Fuel Weight to be Carried given Desired Takeoff Weight

LaTeX Go Fuel Weight to be carried = Desired Takeoff Weight of Aircraft-Payload Carried-Operating Empty Weight

Desired Take off Weight

LaTeX Go Desired Takeoff Weight of Aircraft = Payload Carried+Operating Empty Weight+Fuel Weight to be carried

True Aircraft Speed (Mach number) Formula

LaTeX Go

True Aircraft Speed = Speed of Sound*True Mach Number
V_TAS = c*M_True

What is Maximum Structural Payload Weight ?

Maximum Structural Payload Weight (or mass) is the maximum demonstrated payload to be carried without stressing the aircraft fuselage. Maximum zero fuel weight (or mass) is the sum of the operating empty weight and the maximum structural payload weight.

What is Mach number?

The ratio between the the true air speed (TAS) and the local speed of sound (LSS). This ratio, which equals one when the TAS is equal to the LSS, is known as the Mach Number (M) and is very important in aircraft operating at high speed.

How to Calculate True Aircraft Speed (Mach number)?

True Aircraft Speed (Mach number) calculator uses True Aircraft Speed = Speed of Sound*True Mach Number to calculate the True Aircraft Speed, True Aircraft Speed (Mach number) is defined as the equivalent airspeed corrected for temperature and pressure altitude. True Aircraft Speed is denoted by V_TAS symbol.

How to calculate True Aircraft Speed (Mach number) using this online calculator? To use this online calculator for True Aircraft Speed (Mach number), enter Speed of Sound (c) & True Mach Number (M_True) and hit the calculate button. Here is how the True Aircraft Speed (Mach number) calculation can be explained with given input values -> 684 = 13.1944444444444*4.

FAQ

What is True Aircraft Speed (Mach number)?

True Aircraft Speed (Mach number) is defined as the equivalent airspeed corrected for temperature and pressure altitude and is represented as V_TAS = c*M_True or True Aircraft Speed = Speed of Sound*True Mach Number. Speed of Sound in the air is considered here and is denoted by c symbol & True Mach Number of the aircraft. Mach number is a function of temperature and true airspeed. Aircraft flight instruments operate using pressure differential to compute Mach number, not temperature.

How to calculate True Aircraft Speed (Mach number)?

True Aircraft Speed (Mach number) is defined as the equivalent airspeed corrected for temperature and pressure altitude is calculated using True Aircraft Speed = Speed of Sound*True Mach Number. To calculate True Aircraft Speed (Mach number), you need Speed of Sound (c) & True Mach Number (M_True). With our tool, you need to enter the respective value for Speed of Sound & True Mach Number and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
