Takeoff one way land another

[Col7777]

I recently tried an ai aircraft I downloaded to see how it performed, I tried it At Hawarden EGNR a small airport close to Manchester UK.
I set the flight plan for it to takeoff and land at the same airport, it took off and headed out toward Liverpool then turned and landed from that direction, I thought they had to land in the direction they took off from.
There was no other traffic taking off, if it was a busy airport then it would have been landing facing on coming takeoff aircraft.
I checked the afcad and both runways were open, runway 05 had the R/H pattern ticked, the other end 23 was clear, is this normal?

Hi Col -
This is one of those infuriatingly frustrating things that MSFS does. If you set the flight plan for T&G, the plane will fly proper circuits, but there is no guarantee that ATC will send it to the appropriate runway for the wind direction; and once it has chosen the active runway, it doesn't like to change its mind.
There was some discussion of this in the old forum:

I had something rather similar the other day, namely at EKCH - Kastrup, Copenhagen. I was checking how one flightplan was performing, when I suddenly noticed how all the incoming traffic was turning back halfway the runway, while at the same time the outgoing traffic just took off:




I couldn't quite believe what I was seeing, nor couldn't replicate what was happening later on...

I know sometimes if you start the sim ai needs to settle down and it can do funny things, I recently had 2 aircraft push back at the same time, one turned left the other right and they went nose to nose, after a few seconds one went right through the other then they got in line.

Theoretically you can eliminate the use of one end of a runway by eliminating the Start Location for that end. I've never tried it, but it still wouldn't give you the behavior you describe...

I wouldn't pretend to guess why traffic turned on the runway to find an exit (the choice of exit is made by FS for AI traffic, depending on its planned destination parking spot) but if it does and if the aircraft runs off the edge of the runway whilst turning, ATC considers it as having cleared the taxiway and will give other traffic permission to take-off or land even though it rejoins/fouls it. Another similar, odd happening can be if an aircraft leaves the taxiway and is told to contact ground, but is stopped for some reason with its tail foul of the runway. You will still get clearance to take-off or land.

Another of the AI quirks, taxying AI traffic doesn't respect other aircraft until it departs the gate in a forward direction. Residue of the addition of push-back over the FS2002 AI system, I suspect. They will also quite happily push-back into buildings.

All in all AI has some funny ways but I still think it is quite a spectacular feature of FS.

I am intrigued, though, by the initial item in this thread - the only time I have seen anything along these lines is if the wind changes - I did find this at an arrival in Havana once, but the departing AI traffic was held at the far end after I was cleared to land until I left the runway. I thought it was going to be a mess, but all very respectable, really.

You can say that again, John. Today I was again at Kastrup, testing some ai-flightplans (Transair Sweden DC-3 and Falckair Heron - the latter with another Heron doubling as a Falckair one), and following weird things happened:

- at around 11:35 GMT, a Lufthansa CV-440 (Callsign 'Lufthansa 200') came in from about 4000 ft 9 miles out, pancaking into runway 4R (and consequently disappearing)
- around 12 GMT, a Ryan STA (reg OY-CHI) came in from Sweden, and turned over Kastrup towards Odense. Nothing special, one would say - except that it did so at an altitude which at no point exceeded 5 feet. According to its flightplan, it should have been flying at 7000 ft.
- and then, just when I thought I had seen it all, I saw a couple of airliners approach 4R close to eachother (approx 12:15 GMT). First in row was a Flying Enterprise DC-4m, followed by 'my' Heron (the reason I was running the test), with an Air France Caravelle close behind. However, as the DC-4m was rolling out, a fourth aircraft, a BEA Comet 4 (reg G-ARCO) came in from literally nowhere at 0 feet on the runway treshold and started to roll out. And just behind that, the Heron touched down - so there were in fact 3 aircraft on the runway at the same time (the DC-4m not yet having cleared the runway); the Air France Caravelle, though, waved off.

LOL! Sometimes it keeps me entertained for hours...
