Airfoil geometry as Cd does not matter but yes the formula take account of wing area as S given in ft square Ok in AN2 I got it wrong because it is biplane I calculate 700 based on single wing So intepid estimate could be right 350.Look at the example

An aircraft weighs 30,000 lbs, has a wing area of 750 ft2, and a= 2.2. The runwayfriction coefficients are,:= 0.02 for rolling, and:b= 0.5 during braking. The touchdownvelocity is, and braking occurs when the airspeed is. Additionally,at touchdown speed,
can you stop spoiling this thread with your silly fanboy calculations
if you dont have anything useful to say remain quite and look intelligent than opening your mouth and removing all doubt
