How to Evaluate Minimum Flight Velocity?

Minimum Flight Velocity evaluator uses Minimum Flight Velocity = sqrt((Aircraft Weight/Aircraft Gross Wing Area)*(2/(Air Density))*(1/Lift Coefficient)) to evaluate the Minimum Flight Velocity, Minimum Flight Velocity of an aircraft, often referred to as the stall speed, is the lowest speed at which the aircraft can maintain controlled flight without stalling, stalling occurs when the airflow over the wings becomes too disrupted, leading to a loss of lift. Minimum Flight Velocity is denoted by V_min symbol.

How to evaluate Minimum Flight Velocity using this online evaluator? To use this online evaluator for Minimum Flight Velocity, enter Aircraft Weight (W), Aircraft Gross Wing Area (5), Air Density (ρ) & Lift Coefficient (C_L) and hit the calculate button.

FAQs on Minimum Flight Velocity

What is the formula to find Minimum Flight Velocity?

The formula of Minimum Flight Velocity is expressed as Minimum Flight Velocity = sqrt((Aircraft Weight/Aircraft Gross Wing Area)*(2/(Air Density))*(1/Lift Coefficient)). Here is an example- 589.9388 = sqrt((1800/4)*(2/(1.293))*(1/0.002)).

How to calculate Minimum Flight Velocity?

With Aircraft Weight (W), Aircraft Gross Wing Area (5), Air Density (ρ) & Lift Coefficient (C_L) we can find Minimum Flight Velocity using the formula - Minimum Flight Velocity = sqrt((Aircraft Weight/Aircraft Gross Wing Area)*(2/(Air Density))*(1/Lift Coefficient)). This formula also uses Square Root (sqrt) function(s).

Can the Minimum Flight Velocity be negative?

No, the Minimum Flight Velocity, measured in Speed cannot be negative.

Which unit is used to measure Minimum Flight Velocity?

Minimum Flight Velocity is usually measured using the Meter per Second[m/s] for Speed. Meter per Minute[m/s], Meter per Hour[m/s], Kilometer per Hour[m/s] are the few other units in which Minimum Flight Velocity can be measured.
