True Mach number when true aircraft speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
True Aircraft Speed - (Measured in Kilometer 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 Kilometer per Hour) - Speed of Sound in the air is considered here and is denoted by c symbol.

STEP 1: Convert Input(s) to Base Unit

True Aircraft Speed: 190 Kilometer per Hour --> 190 Kilometer per Hour No Conversion Required
Speed of Sound: 47.5 Kilometer per Hour --> 47.5 Kilometer per Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_True = V_TAS/c --> 190/47.5

Evaluating ... ...

M_True = 4

STEP 3: Convert Result to Output's Unit

4 --> No Conversion Required

FINAL ANSWER

4 <-- True Mach Number

Lifting Force given Friction Force due to Rolling Resistance

Go Lifting Force of Aircraft = (((Mass Aircraft*[g]*cos(Angle between Runway and Horizontal Plane))-(Force of Friction/Coefficient of Rolling Friction)))

Vehicle Speed for Lifting Force Provided by Wing Body of Vehicle

Go Vehicle Speed = sqrt((Lifting Force of Aircraft/(0.5*Density Altitude for flying*Aircraft Gross Wing Area*Lift Coefficient)))

Lift Coefficient for Lifting Force Provided by Wing Body of Vehicle

Go Lift Coefficient = Lifting Force of Aircraft/(0.5*Density Altitude for flying*(Vehicle Speed^2)*Aircraft Gross Wing Area)

Lifting Force Provided by Wing Body of Vehicle

Go Lifting Force of Aircraft = 0.5*Density Altitude for flying*Vehicle Speed^2*Aircraft Gross Wing Area*Lift Coefficient

Operating Empty Weight when Desired Take-off Weight is considered

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

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

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

Desired Take off Weight

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

True Mach number when true aircraft speed

Go True Mach Number = True Aircraft Speed/Speed of Sound

True Aircraft Speed (Mach number)

Go True Aircraft Speed = Speed of Sound*True Mach Number

Speed of Sound (Mach number)

Go Speed of Sound = True Aircraft Speed/True Mach Number

True Mach number when true aircraft speed Formula

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

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 in aviation?

The Mach number is the ratio of the speed of an object to the speed of sound. In aviation, the mach number is the ratio of the true air speed of the aircraft to local speed of sound, which can vary due to atmospheric conditions, air temperature and density.
