AI Helicopters and runways in FSX

[F70]

First post on this forum so be gentle with me.

Making for years in FS9 and FSX airport scenery's always for the civil planes,but now i want to start with some military airports.

I have for a test in FSX two airports with parking places.(10 M)
The runway is 300 M (900 ft) and 0 M,a grass-runway.
Taxiways are 5 M grass and a hold-short node.
I have a ATC and tower.
I have four types of helicopters,a Sikorsky HH-60J JayHawk,HAR-3 Sea King v5.0,Chinook_HC2_RAF and a AH-64 Apache.

The Apache and the Chinook taking off normal but they are never land the ATC say every time go-around and if they make a go-around they going miles away they going out off my view.
The Sikorsky and the Sea King taking off normal and they landing normal and if they make a go-around they make a small circuit and landing normal.

It's are overlay airports LPM1 and LPA1,i have experimenting with different length of runways but it stay the same.
Is this a FSX problem or must i search it in the overly airports or the .air file.

I have searching this forum but can't find anything what can me help.

Hi Jan

Just a quick thought off the top of my head, but are the the chinook flight plans IFR & the seaking VFR, as an IFR flight plan will send an aircraft miles off before landing, where a VFR plan will keep it closer to the airfield for landing? Like I said, just a thought.

Thanks Dave for your replay,

No all my flight plans are VFR,i have try different flight levels from FL 60 to 1000 ft, but i think they don't fly the flight levels.
The airports are about 15 miles apart.

But no panic,i like the small problems,search and try.

I don't have FSX so I am making an educated guess here, but sometimes aircraft won't land if the AI engine thinks that the runway is too short for them. If they land successfully at other strips then try lengthening the runway a touch until they land OK.

I have just noticed that you have stated that the runway is 300M long & 0M wide. Try a runway width of say 5 or maybe 10 ft. That may be the problem?

Thanks all for your replay,

I am still experiment with the heli airports,i have now a 300 M by 30 M runway in grass .
I use the Sikorsky HH-60J JayHawk in the flight plan and have a flightplan for five heli's with a interval of 3 min.
So the first heli land normal and sometime the second also,but than say the ATC by the third one "go around" and i don't know why,runway is clear all the heli's are on the parking spot and i have many parking spots.
And then start the trouble,the heli make the go around and heli four is on his way,first say the ATC,"clear to land follow the heli on up wind" ,and when heli four is on final the ATC say "go around" and this stay for the next try to land ,so the heli's continue to follow each other but no one is landing until three attempts, and then they disappear.

I hope you can follow my story,i can't.

Anyway i think the runway trouble is now clear to me,almost,experimenting some more.
Now the ATC trouble,maybe the AI engine from FSX going mad.
There is a airport on 1 mile,20 airplanes,airport on 8 miles 40 airplanes,airport on 10 miles 25 airplanes,airport on 15 mile 10 airplanes.

I can only speak for FS9 but it may apply to FSX. If there are no parking spots the aircraft only check for that on the ground and disappear if there are none.
One reason that the aircraft disappear is that there is something on the runway. If you are using an aircraft viewer like TVB you may be interfering with the runway causing the go arounds. This would explain why two landed OK.
Also check your afcad to make sure that you have all the entrances/exits to the runway with the correct nodes set.

I think it has all to do with the MAIW Apaches,they never land,so i stop with the Apaches.
I have now a over-lay in EHGR in the NL2000v4 the EHG1 and everything going fine.

The runway is 275 M by 0 M and the taxiways are also 0 M.
I use the MAIW Seaking,MAIW Chinook and the Sikorsky from Hovercontrol,all AI heli's.

Maybe some fine tunning on the heliport,the heli's use a small part of the runway,or maybe not,the runway is invisible.
Anyway thanks for your replay.

Some time is it simple,if you know it.

Seek and ye shall find.
I have now EHG1 working,they fly from EHG1 to EHG1.
The MAIW Apaches and the MAIW Chinook landing normal now.

What was the point? In Runway - Properties - Pattern Altitude in the box was for the altitude 457 M,i have change this to 100 M and all my helicopters landing.

Next project,let see if they will fly from one airport to a other airport.

That's interesting it may be that FS says that for a runway that small your circuit height can't be that high. Something useful to store away at the back of your mind.

[F70]

I have test it first for EHG1,a overlay airport in EHGR,they fly a circuit EHG1 to EHG1.

Now i have two overly airports in EHGR,EHG1 and EHG2 and they fly from parking spot to parking spot.

Thanks to the MAIW for making the heli's.

Guys,

I have found in FS9 that 500 foot AGL pattern altitudes work best for consistent helicopter landings on short helicopter runways and also prevent conflicts with fixed wing AI aircraft flying at a regular runway's pattern altitudes of 1000 feet AGL and above. All of my AI helicopter FDE's, including those for Nick's NBAI Apache and Chinook, were developed using short runways of 500 to 800 foot lengths and 500 foot AGL pattern altitudes

That ties in nicely, thanks Mike.
