Airfield Requirements

[The Avgasdinosaur]

Can anyone point me to a web site that lists take off length and landing length required for classic aircraft E.G. DC-3, DC-4, B25, HU-16, PBY-5A, Beech 18 etc etc ?
I realise not all these are warbirds per se but you get the general idea.
Thanks for your time and trouble, I've googled all sorts without sucess.

David: I think that you are going to find that all of those require either running some calculations based on conditions or running a nomagraph to do the same thing, to get field length requirements. Weight, wind, temp, altitude and surface type and condition are all going to factor into the numbers. I know our birds at work all have takeoff performance charts based on those factors and others, including weapons loads and symmetry. Based on the sum of the conditions, the required distances are going to vary.

And don't forget ambient tempratures. Several years ago airliners out of SKY HARBOR in KPHX were prevented from taking off @ certain times of the day when the OAT exceeded the engine trim charts for JT 8's on 727's, 737's, and DC-9's I believe the static air temps were well over 130 f and higher.

If you have a specific airplane in mind, the info/performance charts would be in the POH. Some of them are easier to find than others but if you know anyone who has/flies the aircraft you're looking for maybe they can scan a copy of the t/o distance data for you. Like the other guys said, there's no hard number for any airplane as it depends on many factors.

Once you get the chart you're looking for, the next step is trying to interpret it which is a topic in itself.

Here's a link to some of the data you'd be looking for on a B-25. Finding the documents for some of those other aircraft may require purchasing CDs with copies of original flight manuals.

Just remember that what we call a "POH" (Pilot's Operating Handbook for those unaware of the acronym) is a relatively (1970s) term and the data you're looking for might also be found under "Flight manual" or "operating instructions" or "Operating limitations" or some AAF form like I think our L-5 has (can't remember the title right off the top of my head).
