Hi Guys - Iv just re-installed the PMDG 747 and Mega Airport Heathrow (EGLL)All fine, but when i tune to EGLL to get landing clearance, and choose Select Another Runway, there are no runways in the list (only 9L, what ATC always give me).Any ideas what that could be, and how i maybe able to put the runways back in?Thanks!

Hi Adrian,That's because 9L is the landing runway at Heathrow and the developpers probably set the Afcad file that way to match realism.It's easy to open and close runways if you have the AF2 program, in the menu above go to list, runways, open the runway and check or uncheck whatever you desire.

if you have the AF2 program

Thank you very much for your reply. What is the AF2 program?So Heathrow only uses 9L for landing? Seems strange that if im approaching from a direction that 27R / 27L would be best for landing, i have to turn 180 degrees to hit 9L. Still, not to worry! :-)

Sorry mate, not sure where you got that idea from but it's not correct, 27L/R is used for landing or departures unless the tailwind is more then 5 knots to keep noise for us Londoners to a minimum :)Rob

Yes yes, I should have checked the Jepp chart first!What I meant was that probably one runway is assigned for take-off and the other for landing in order to facilitate AI traffic flow in that scenery.In the original poster's case I suspect the AF2 file is set up as 09L-27R is for landings and 09R-27L for take-off only.Adrian, the AF2 program is an airport editor, it's very useful and easy to use. However, since the library is down I don't know if it's available on other FS sites.The AF2 file should be in the FS9/Addon Scenery/Mega Airport Heathrow/Scenery folder. You're looking for a file which would have "AF2" in it's name.Tell me if you to find it, drop me a PM if you want.If you do, send it to me and I'll fix it for you.EDIT: I'm not sure if it's the norm but most aircraft seem to land on 09L and depart from 09R (when 09s are in use) at Heathrow on spotter shots.

As far as I'm aware the runway usage is alternated between the two on a rotation so that it alleviates noise for half of the day under each flight path. That certainly used to be the case, and since it seems an eminently sensible thing to do, I don't see why they would have any reason to change it.Al

The last version of AFCAD is I think 2.21 and is in the Must Have files section of flightsim.com. Free registration is required to download.

The straight dirt from Mr.JEPP......1.2.2. PREFERENTIAL RUNWAY SYSTEMWhen tailwind component is not greater than 5 KT on RWYs 27R/L, these RWYs willbe used in preference to RWYs 09R/L, provided the RWY surface is dry.Pilots asking for permission to use the RWY into the wind when RWYs 27R or 27L arein use, should understand that their arrival or departure may be delayed.Does the new AFCAD have this modeled? Is it even possbile Onur (I know you like to edit AFCADS)?

Well, with afcad it's better to assign one operation to a given runway (both ends) otherwise you may get weird behaviour.The scenery must have 09L-27R for landings and the other one for take-offs precisely to prevent ridiculous tailwind take-offs or landings.

Agreed Onur. In RL I see they do it this way too, in any WAR DVD EGLL landing I have seen at least.

As an ex-ATC member at EGLL, I can advise that all of them are used at some time or other, including 23 when the winds are very unusual.The preference is for 27L and R with one for deps and one for arrivals, because of the obvious issue of London to the east, and the coast to the west, and typical wind conditions always favourable for this setup. That said, they swap (or used to - it was many years ago) at 1300 so that whichever was doing departures became arrivals and vice versa to give suburbs underneath flight paths a break.09L and R would be used if winds changed to the extent noted above. (I once had a bawling member of the public call the tower and inbetween sobs advise that she had just bought a property in inner London somewhere, and had deliberately watched flight routes for weeks noting that her intended home was not subject to overflying jumbos. The week she moved in, winds changed, and we switched to easterlies, which put our aircraft over her house for the first time in about 8 weeks. I recommended she have strict words with her solicitor who should have advised her better......).The other thing to note is mornings. Oftentimes, if 27R was being used for landings, we might also land on 27L at the same time if the aircraft in question was a long hauler looking for Terminal 4, which was south of 27L. This would allow it to land and vacate left from 27L straight into T4, and avoid the need for a crossing of runway later. Doubt FSX can be that clever but wouldnt it be fun if it could??Hope this explains...ravey
