Hi

But how would you know when you plan your flight how long any delays might be, I've often flown from busy airfields when I've been held up waitng for wake turbulence to clear, but wouldn't know it would happen at the planning stage. For hire purposes don't you log brakes off to brakes on times? Skydemon does log takeoff and landing times which I find particularly helpful, but that doesn't solve your problem does it. good luck

I see what you're saying NJE with regards to not knowing actual delay times. What I was proposing was rather more of an average value I suppose. For example, barring any major issues, I know that from engine start to take-off clearance, it takes somewhere between 10-15 minutes and on return its about 5 minutes taxi back to the apron
