What is the PCN for: A320, 737, Dash 8 and any similar types and models.

What is the TOR required at MTOW for: A320, 737, Dash 8 and similar types and models.

I'm very interested to hear from Pilots experienced on type.

:ok:

Alot of variables in there, engines, flap setting, type of aircraft, climb gradient etc I suggest you be a bit more specific and you might get some numbers.

What type of aircraft could land and TkOF on a 1600M strip of medium strength, flexible pavement and 500 Kpa at MTOW or MLW, or can't you? Types or similar to those previously stated thankyou.

I just want one person to give one example in the hope many people will give many examples.

Whats medium strength? PCN 8? 15?

With a max TP of 500kPa - I'd start with eliminating all the aircraft with a TP higher than that.

Got any left?

OK - I'll give it a bash.

The Dash 8 Q400 has ACN between about 15 and 21, depending on rigid/flexible and category of surface.

We don't really think about TORR practically in day-to-day operations. We simply limit our BRW according to the TODA/ASDA/climb gradient requirements and temperature. This is all pre-calculated for each runway. A host of other issues impact on max weight for a particular runway, such as icing conditions and MEL items. Flap setting and use of bleed air also come into play.

Some indicative Dash figures (unfactored) by model (metres):

100 - STOD 1050 LDR 450
200 - STOD 1000 LDR 500
300 - STOD 1500 LDR 600
400 - STOD 1700 LDR 800

STODs based on normal T/O flap setting and LDR on maximum flap. All ISA, MSL runway with zero slope or wind.

And now for the disclaimer. I would usually tell you that anything that comes from my keyboard should be discarded as a matter of routine. On this occasion, I really must stress that these figures (though not completely pulled out of my a@#e) are indicative only, and anyone who attempts to use them in flight planning (or even just tries to pin me down on the numbers) is engaged in idiocy of Baldrick-esque proportions.:p

From charter ops years ago, Dash8-100(at 90psi) 13, F28-1000 16, Saab 2000 17, Bae146-100 21. Usual disclaimer applies!

Thanks chaps/chappettes. :)

Does anyone have an ACN + approx LDG and TKOF figures for 737 models and A320?
