Hi all,

Would an F27-500 be able to land on a 1,700m runaway (asphalt) at 5,100ft ? Average temperature is 30 deg C

I won't have access to the performance charts for the aircraft until mid this week and can't find anything on the internet but need an answer in 24hrs for a potential deal.

Thanks !

Not a problem, did so with an FH227B (very similar) years ago.
However, departure would require water/methanol and 16 flaps for takeoff.

Thanks 411A

How much runway ? 1,500m ?

I wouldn't have thought there was much room for error in pilot technique

That is cutting it close, but yes, will work....provided W/M is available, and used.

The 'ole Dart engine is a wonderful reliable unit, but needs W/M for optimum performance at higher altitudes/higher temperatures, make no mistake.
Personally, over 5000 hours in these airplanes, never had a Dart engine quit...RollsRoyce engines, superb.:ok:

aseanaero Try Googling www.bacgroup.co.uk/pdf/special%20offers.pdf (http://www.bacgroup.co.uk/pdf/special%20offers.pdf) and scroll through to page 7 of the document, Airfield Performance Data, which you may find helpful as indicative information.

Thanks Old Fella

Although it doesn't go up to 5000ft elevation there's a lot of useful info in there for me to swat up on

Got to love this forum for digging out info ! :ok:

aseanaero. I am unsure just which models of F27 were used in PNG, however I do know they used to go into Goroka at 5200' AMSL and max rwy length available 5400', also into Mt Hagen at 5350' AMSL and max rwy length available about 6200'. Cheers Old Fella.

It operates into London City which is shorter (I think 1400m)

At those elevations and temperatures you need to think about approach/climb and landing/climb limits. The runway length part of the equation is the easy bit, for landing anyway. It will stop easily in 1500 metres on a dry runway. Depending on obstacles, you could be looking at zero flap for the takeoff to get the required climb gradient, so it starts to get tricky because that really affects accelerate-stop in a big way compared with 16 flap.
And you don't want novice pilots doing 26 flap landings in a -500 because eventually someone WILL scrape the tail.

Operated F27-600 for several years out of Lesotho.

Elev 5100' Rwy 1380m

No probs at all even in summer 30c. 40 Pax although route time was only 1h30.

Water Meth was needed as 411A says.

the only f-27 that are operated in the us are fedex feeders and they just retired the old birds. there is a skydiving outfit in the southwest that still operates one. the dart engine is very reliable and in the 25+ years our company operated the F we only had 2 engine failures and i got one of them . plane does fine on one.
