Aircraft Thrust = 1.44*(Weight^2)/([g]*Freestream Density*Reference Area*Maximum Lift Coefficient*Liftoff Distance)
T = 1.44*(W^2)/([g]*ρ_∞*S*C_L,max*s_LO)
This formula uses 1 Constants, 6 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Aircraft Thrust - (Measured in Newton) - Aircraft Thrust is defined as the force generated through propulsion engines that move an aircraft through the air.
Weight - (Measured in Newton) - Weight Newton is a vector quantity and defined as the product of mass and acceleration acting on that mass.
Freestream Density - (Measured in Kilogram per Cubic Meter) - Freestream density is the mass per unit volume of air far upstream of an aerodynamic body at a given altitude.
Reference Area - (Measured in Square Meter) - The Reference Area is arbitrarily an area that is characteristic of the object being considered. For an aircraft wing, the wing's planform area is called the reference wing area or simply wing area.
Maximum Lift Coefficient - Maximum Lift Coefficient is defined as the lift coefficient of the airfoil at stalling angle of attack.
Liftoff Distance - (Measured in Meter) - Liftoff Distance is the portion of the takeoff procedure during which the airplane is accelerated from a standstill to an airspeed that provides sufficient lift for it to become airborne.

STEP 1: Convert Input(s) to Base Unit

Weight: 60.5 Newton --> 60.5 Newton No Conversion Required
Freestream Density: 1.225 Kilogram per Cubic Meter --> 1.225 Kilogram per Cubic Meter No Conversion Required
Reference Area: 5.08 Square Meter --> 5.08 Square Meter No Conversion Required
Maximum Lift Coefficient: 0.000885 --> No Conversion Required
Liftoff Distance: 523 Meter --> 523 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T = 1.44*(W^2)/([g]*ρ_∞*S*C_L,max*s_LO) --> 1.44*(60.5^2)/([g]*1.225*5.08*0.000885*523)

Evaluating ... ...

Coefficient of rolling friction during ground roll

LaTeX Go Coefficient of Rolling Friction = Rolling Resistance/(Weight-Lift)

Lift acting on aircraft during ground roll

LaTeX Go Lift = Weight-(Rolling Resistance/Coefficient of Rolling Friction)

Weight of aircraft during ground roll

LaTeX Go Weight = (Rolling Resistance/Coefficient of Rolling Friction)+Lift

Resistance force during ground roll

LaTeX Go Rolling Resistance = Coefficient of Rolling Friction*(Weight-Lift)

Thrust for given liftoff distance Formula

LaTeX Go

Aircraft Thrust = 1.44*(Weight^2)/([g]*Freestream Density*Reference Area*Maximum Lift Coefficient*Liftoff Distance)
T = 1.44*(W^2)/([g]*ρ_∞*S*C_L,max*s_LO)

Can planes stop in the air?

No. A plane doesn't stop in midair. Planes need to keep moving forward to remain in the air (unless they are VTOL capable).
