ATR42-500 T/O and Landing performance
Hi,
Did some research on the ATR website and the WWW but didn't find anything specific regarding the following:
Can a ATR42-500 take off and land at an airfield with a 800m runway? Operating conditions: ISA+25, 340NM (170+170), average pax. weight 75kg +10kg baggage per pax.
I believe it is possible (What a great performer
)!!! But under which conditions (fuel, seat config., etc.).
Appreciate your help guys!
Cheers,
mulu

Actually, i'm not surprised that you can't find thiat info to even get a basic answer to your question you have to go the the performance data (which even on the smallest GA aircraft presents a blinding array of charts and graphs)

however this can be approached in several ways
1. "340NM (170+170)"
(JAR 25??) Payload/range for a 0.6x M cruise
these charts may list the assumed number of pax?
2. "ATR42-500 take off and land at an airfield with a 800m runway? Operating conditions: ISA+25".
JAR 25 take off rwy length standard day + 25, may assume ZER0 wind and ZER0 rwy gradient..ditto JAR Landing RWY required.
Obstacles are another thing
Boeing provides basic wat curves on its site but you have to look carefully to get to them perhaps ATR does the same...I can't be any more helpful somebody will tell you here...rhov

I remember seeing pictures of an Atlantique ATR 42 doing touch and goes on Wellesbourne's runway 18/36, which is 981 m long. OK, that was without PAX and probably with a light fuel load (Coventry is only about 15 nm up the A46), but they obviously practiced short-field ops for a reason...

Fianl 3 Green as a US Scientist I'm used to metric but that's not even good enough in all cases, now most stuff is SI...but i also like my miles, gallons pounds, ounces, quarts, for every day stuff i outside of the lab I forget what a liter is ...sorry cu. dm aaaaaahh units units units
) when I posted this. It's ISA+18, and it's degree Celsius!!!
Don't know about 42-500 by I can give you some figures for -300, hope this might help.
For 800m RWY, 0ft elevation and 33°C, MTOW is 13 500kg and MLW about 14t (for ALD/RLD=0.7). ATRs I fly have DOW 11200 kg which leaves 2300 kg for fuel and payload. 170 Nm trip with alternates near to destination requires 1200 kg take-off fuel and 340 Nm about 1600. Typical landing fuel at destination is 700-800 kg. Therefore 42-300 would be able to take out 13 pax on a 170 Nm trip, 8 on 340 Nm one and bring in about 23 pax.
As -500 series has 30% more power I suspect it would be able to pick up some more passengers, but whether it's one, two or five - we'll have to wait for someone current on -500 to answer.
