Just a quick guess, related to GA. No flap and you'll accelerate more quickly, to a slightly higher takeoff speed.
With flap the takeoff speed will be, say, 5 knots lower but the increased flap drag will reduce the aircraft's acceleration.
I've read a couple of GA articles where a short field operator starts with no flap and drops takeoff flap as he approached Vr.

Quite a good article and one I'd recommend everyone reads. Having done so then I'd ask you all a simple question. What are the advantages and disadvantages of using flaps for take off - and using no flaps? Simple question but let's see how much you've learnt after all these years using FS. bones -----Original Message----- From: jhb_airlines-bounce@xxxxxxxxxxxxx [mailto:jhb_airlines-bounce@xxxxxxxxxxxxx] On Behalf Of Paul Reynolds Sent: 08 September 2007 15:08 To: JHB List Subject: [jhb_airlines] Short or Soft field techniques Rummaging through my bookshelf, I came across a copy of the manual that accompanied Papa Tango's Airfiled for FS95/98. Nothing remarkable there. However, opening it I discovered a section on techniques for both soft field landing and take offs and short field landing and take-offs. I have scanned the relevant pages and attached them. Paul
