Clearway Distance for Continued Takeoff Solution

STEP 0: Pre-Calculation Summary

Formula Used

Clearway Distance = 0.5*(Distance to Clear 35 ft Obstacle-Liftoff Distance)
CL = 0.5*(D₃₅-s_LO)
This formula uses 3 Variables

Variables Used

Clearway Distance - (Measured in Meter) - Clearway Distance is the difference between takeoff distance available (TODA) and takeoff run available (TORA).
Distance to Clear 35 ft Obstacle - (Measured in Meter) - Distance to Clear 35 ft Obstacle is defined as the distance required to clear an 11 m (35 ft.) imaginary obstacle on the runway.
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

Distance to Clear 35 ft Obstacle: 1600 Meter --> 1600 Meter No Conversion Required
Liftoff Distance: 510 Meter --> 510 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

CL = 0.5*(D₃₅-s_LO) --> 0.5*(1600-510)

Evaluating ... ...

CL = 545

STEP 3: Convert Result to Output's Unit

545 Meter --> No Conversion Required

FINAL ANSWER

545 Meter <-- Clearway Distance

Liftoff Distance given Clearway Distance for Continued Takeoff

Go Liftoff Distance = -((Clearway Distance/0.5)-Distance to Clear 35 ft Obstacle)

Distance of 35 ft Obstacle given Takeoff Run

Go Distance to Clear 35 ft Obstacle = Takeoff Run in Clearway+Clearway Distance

Clearway Distance given Takeoff Run

Go Clearway Distance = Distance to Clear 35 ft Obstacle-Takeoff Run in Clearway

Takeoff Run for Continued Takeoff

Go Takeoff Run in Clearway = Distance to Clear 35 ft Obstacle-Clearway Distance

Distance to clear 35 ft Obstacle for Clearway Distance for Continued Takeoff

Go Distance to Clear 35 ft Obstacle = (Clearway Distance/0.5)+Liftoff Distance

Clearway Distance for Continued Takeoff

Go Clearway Distance = 0.5*(Distance to Clear 35 ft Obstacle-Liftoff Distance)

Field Length or Total Amount of Runway needed under Continued Takeoff

Go Field Length = Full Strength Pavement Distance+Clearway Distance

Clearway Distance given Field Length under Continued Takeoff

Go Clearway Distance = Field Length-Full Strength Pavement Distance

Clearway Distance for Continued Takeoff Formula

Clearway Distance = 0.5*(Distance to Clear 35 ft Obstacle-Liftoff Distance)
CL = 0.5*(D₃₅-s_LO)

What is a Runway Clearway?

Runway Clearway is a defined rectangular area on the ground or in the water at the end of a runway in the direction of takeoff and under the control of the competent authority. It has been selected or prepared as a suitable area over which an aircraft may make a portion of its initial climb to a specified height.

What is Landing Distance?

Actual Landing Distance is the distance used in landing and braking to a complete stop (on a dry runway) after crossing the runway threshold at 50 feet; and, Required landing distance is the distance derived by applying a factor to the actual landing distance.

How to Calculate Clearway Distance for Continued Takeoff?

Clearway Distance for Continued Takeoff calculator uses Clearway Distance = 0.5*(Distance to Clear 35 ft Obstacle-Liftoff Distance) to calculate the Clearway Distance, Clearway Distance for Continued Takeoff is defined as difference between takeoff distance available (TODA) and takeoff run available (TORA). Clearways originate from end of takeoff run available. Clearway Distance is denoted by CL symbol.

How to calculate Clearway Distance for Continued Takeoff using this online calculator? To use this online calculator for Clearway Distance for Continued Takeoff, enter Distance to Clear 35 ft Obstacle (D₃₅) & Liftoff Distance (s_LO) and hit the calculate button.
