Possible Mid Air Collision

[MSYAIRTRAN]

I was landing at IAD on RWY 19R When I was about 2000 ft from touchdown I took a nosedive before I was at the beginning of the runway. This caused me to land with a 2551fpm landing. I beleive it might been a mid air colission The AI was also landing on RWY 19R any sugestions? Now I got to refly the routh because it was above 800fpm.

I don't think so. If you have detection of crashes turned on you would have been knocked right out of the sky and the game would have ended. If you don't have it turned on, AI aircraft will fly through you without any disruption to your flight.

Did you have Active Sky Evolution running? It may have been wake turbulence.

With collision detection:



wouldn't be so irritating if the AI ended up in the same condition

I did the same flight last night. I was cleared to land and was about 500 ft AGL all of a sudden hard dive causing yet another 3000fpm landing. it happened on the same runway as before 19R at IAD could this have something with the wind at this airport?

Are you making a visual or an instrument approach? If your are performing an ILS landing using the autopilot, there could be something wrong with the ILS at that specific airport.

I did a ILS approach. I checked the airport in my AFCAD program ane everything looked ok. I use Radar Contact as my ATC and they put me on final clear to land then boom instead of a smooth touchdown it threw me off course right at the threshhold. I had a landing of 3088fmp which would result in a damaged nosewheel.

Do you mean you keep the AP on until touchdown? Usually, you should fly the last 500-700 feet manually until the plane reaches the ground. The autopilot behavior can become erratic at that altitude and many things could interfere with the ILS signal.

Good luck!

Try it with the clear weather theme in FS so there are no winds to exclude turbulence. In FS9.cfg there is also a global turbulence scale parameter by default set to 1.000000000 or similar. I use 0.3.


(RC does not have anything to do with what you are describing.) Turn off ai to insure there is no collision involved but generally they pass through you as stated. ai will produce wake turbulence but thart is not settable in FS9 .cfg.

If you are landing into gusting headwind components increase your landing speed by half the gust value to prevent stalling at landing IAS. In addition some aircraft models need a bit more landing speed than indicated. Insure you have burned enough fuel so you are not overweight for landing nor have gotten out of your CG envelope. Be sure you are following the flaps schedule for landing and know what the landing v-speeds are. In addition insure your trim is set correctly for landing so the AP does not run out of trim range.

A good utility I prefer is aismooth version 1.2 in the FSX utilities section. It runs on FS9 as well and you can set it for ai separation from each other and you. You will neeed to have FSUIPC3 installed for that but you wil not need the paid registration for that. FSUIPC3 latest version is here:

and you should have that installed for RC as well.

I suggest downloading the single .pdf bundle to look at the airport diagram and the approach plates.
