1.	The curly bracket in the accelerating force represents the net propulsive thrust- weight ratio.(a) True(b) FalseI have been asked this question by my college director while I was bunking the class.My query is from Estimation of Take-off Distances in division Take-off and Landing Performance of Aircraft Performance
Answer» Right answer is (a) True Explanation: The formula for ACCELERATING force is given by: \(\frac{F}{W}=\Big\{\frac{F_N}{W}-\mu_R-sin\gamma_R\Big\}-\frac{L}{W}\Big(\frac{C_D}{C_L}-\mu_R\Big)\) where F is force, W is weight, μR is runway COEFFICIENT of the rolling friction, γR is runway slope, L is lift, CD and CL are the coefficients of drag and lift. The curly bracket in the accelerating force REPRESENTS the net propulsive thrust- weight ratio.
