Be careful.
I get the feeling you are recently new to this. Please don't use full flap to TOFF in any mountainous area. Nor should you learn ridge crossing techniques from a website.
Be humble, listen, filter out the BS, check everything yourself (fuel, caps, weights etc) and always give yourself a margin for error- eg do all calculations and considerations (can i take/make that) on the safe side.
As Feather#3 says, go on over to D&G and see if some of the current PNG "shags" will throw in some stuff- i am sure they'll be glad to rattle on (much like i am doing
) But please just file this info away. If you need it someday, maybe it will save your life- if you make it a way of life- go figure.
Sure rolling starts reduce your strip used, but more importantly reduce the wear and tear on your prop from stone damage. If you are using rolling starts to get out of an airstrip you are pushing it too hard. And full flap? Sure i have used it, at the last minute... because i f*cked up. One example that comes to mind TOFF from 5500'alt, short wet muddy strip, d*ckhead (thats me) loads up too much cr*p and barrels off. Next second, and a couple of mud holes later, i am about to become a 600hp brushcutter. Select full flap to save my job... pop up over said bush, but i had to trade, and luckily i could as the overrun was a valley. Plenty more war stories but i will spare you all, and some that still make me shudder and wonder "how the hell?". My point though is i didn't plan to use it but it saved my arse when i needed it. But i needed it because of my own oversight in the first place, so moral is "don't push it". Here endeth the lesson.
While you are over on D&G ask if anyone can post a copy of "A Potpurri of Bush Techniques" written a while back by an old-hand MAF driver in PNG. It is well worth the read and he has wiser words than i could hope to achieve. I have a paper copy but it is a continent and hours of searching away.
