Hi Guys!I am desperately looking for the tables, so I can calculate the maximum take-off weight allowed, when I know the temperature and the runway lenght! I've posted about it before, and I've searched the internet thin looking for these performancetbales, but no luck!They must be out there some where...Any help is appreciated!RegardsMas

Full name please. I've not seen runway distance tables either, and they would have to be based on altitude or density altitude as well. How short of a strip are you trying to use?

Sorry for the name ;) Martin Jensen here!I've had troubles when flying the IFR World Tour, Dangerous Airports on IVAO. Last airport was ENSR in Norway, with a strip of 1056 m. long.I tried once with 32 passangers and about 650 fwd cargo and around 250 aft (or vice versa - it's a long time ago now).The rwy was too short, as I kinda figured even before I took off, so I aborted T/O and just made it back to the terminal to offload som PAX ;)As I have all available data of the airport, it would be nice to be able to do the correct "math" prior to t/o. I'm sure it's possible, and I doubt that real world pilots just make a qualified guess, before attempting a short runway ;)RegardsMartin Jensen

I agree Martin, but I wouldn't even try flying the Cessna 414 out of 3300 ft. Nice thing about simulation is you can try different things without breaking something, were you able to get off with a lighter payload? The problem isn't the runway required for takeoff as much as that required for an rejected takeoff (RTO), which is longer. That kind of data is usually developed for each runway for commercial operations with lots of documentation for the regulatory agencies. That stuff is hard to find in a PC simulator or even on the internet.

Martin,As Dan mentioned, the data you seek is runway specific and dependant on many factors beyond the ones you mentioned. In addition to runway length and temperature, the MTOW depends on field elevation, APR armed/disarmed, runway condition, obstacles, minimum climb gradient, takeoff technique, and all kinds of things that are unique to an individual runway.It's nearly impossible to apply the data for one runway to another, but if you're looking for a ballbark figure, the shortest runway I have information for is 4450ft long at Sea Level (Newark - EWR Runway 29 from taxiway Romeo).With the APR ARMED, at 90F/32C, the Runway Limit is 20,330lbWith the APR ARMED, at 80F/27C, the Runway Limit is 20,600lbWith the APR ARMED, at 70F/21C, the Runway Limit is 20,920lbWith the APR ARMED, at 60F/15C, the Runway Limit is 21,200lbWith the APR ARMED, at 50F/10C, the Runway Limit is 21,490lbWith the APR ARMED, at 40F/4C, the Runway Limit is 21,850lbWith the APR ARMED, at 30F/-1C, the Runway Limit is 22,230lbWith the APR ARMED, at 20F/-6C, the Runway Limit is 22,450lbWith the APR ARMED, at 10F/-12C, the Runway Limit is 22,590lbWith the APR ARMED, at 0F/-17C, the Runway Limit is 22,750lbWith the APR ARMED, at -10F/-23C, the Runway Limit is 22,800lbThe data covers all the temps in between, but I'm not going to transcribe all of that here. I've tried going through the ASAP book to compile a reasonable cross section of data for a range of runway lengths, but given that all of the airports are at different elevations, and each runway has different characteristics, there's just no way I can put together a meaningful set of charts based on the data I have.Given that the data above is for a Sea Level airport, it's not giving you the worst-case scenerio. So I wouldn't use those numbers if the the 4500ft runway you want to use is at 3,000ft MSL.

Very nice, Nick. I notice every 10F removes about two fannies (very roughly)

So it becomes a male only flight..(Very different meaning in other regions :( )It's ok I'll get he door on the way out :(

thanx a bunch for the replys!I can definately use the numbers - thx!I also used the tables in the tech-brochure from jetstream41.com, and together with Nick's numbers, I guess I can come pretty close to a "safe" calculation.Happy flying!Martin
