DC9 Takeoff Roll Minimums

Fri Feb 22, 2002 1:02 pm

I saw a DC-9 takeoff at KFTY (atlanta charlie brown field) today. It took every bit of the 5000 ft runway. One of the ramp workers said the Navy flies them in here occasionally. 5000 feet just seems really short to me! He said Bob Dole's 727 flew into KFTY a couple of times as well.

So, does anyone have the actual minimums in standard atmospheric conditions for these two planes?

I'd also be interested in others... DC-10, L-1011, 747..

In SAS we used to regularly operate the DC-9-41 from 1,600-meter runways,the T/O roll being some 1,100-1,200-meters.We could operate the DC-9-21 into 1,400-meter runways.Not at maximum weights,but with a full house and fuel for 1:50 hrs sector.

LGA had DC10's and L1011's on 7000ft. Also, they have had 764 from DL in there and DL763's 762's are regular visitors.

SNA has A300/A310/757 on 5700ft.

According to worldaerodata.com the 08/26 RW at KTFY is:
- 5796ft/1767m long
- elevation difference of only 14ft/4.25m i.e. 0.25% uphill/downhill slope
- 800 ft above MSL
If we presume it exist the following conditions at the airport:
- zero wind
- 68°F/20°C
- dry RW
The safe MTOW for a DC-9-32 / JT8D-9 with 5° flaps will be:
This is pretty low TOW compared to the MTOW of the DC-9-32, which is 110,000lb/49.5tonne.
Headwind and colder conditions would have increased this TOW.

When the DC-9-20 was in production Douglas (McD-Douglas?) said in an ad that it could use 3600-ft runways. EA (and PA?) 727s flew out of STT when its runway was officially 4650 ft (though the actual length of pavement may have been a bit more).
