Post subject:  Definitely something wrong with the approach to EGGD Bristol

Have a look at this please. This was today's flight from Exeter with the co-pilot in control.

First of all, earlier in the flight I'm sure one of the controllers said expect runway 26. Then there were some truly crazy directional instructions for approach to Runway 27 and no instruction to reduce altitude to 2500 which is the maximum for an ILS capture at this airport.

Ignore the way I finally got it down manually. I think I even touched the ground before getting it on the runway! :oops:

You are right, there was "expect ... runway 26" first (and the 020 looks strange here, too):

Maybe it carried over from your departure airport, because the "expect" call was about 30 seconds before the runway was determined?

Or maybe PF3 got confused, because it seems your runway 27 for EGGD has a runway heading of 264:

End of data for EGGD WP:2
Which scenery do you use for EGGD? The P3D data coming with PF3 has the runways at exactly 270 (and 90).

Regarding the altitude: EGGD is at 622 feet. If you do not configure something different, PF3 uses airport altitude + 3000 feet rounded up to the next 500 or 1000, so 4000 feet is expected here.
You can configure different FAF altitudes per airport as needed.

Hi Thomas

As with all my other UK scenery, I use UK2000 Bristol Xtreme over an enhanced (with addons) Horizon Photo Scenery.

You're right, the runway is at 622'. However, the default P3DV3.3.5 ATC (as with all the previous and MS FSX etc) when flying IFR always brings you down to 2,500 for approach, seemingly because that is the height at which the ILS will lock on. Anything higher and the ILS doesn't work.

Thanks for the tip about configuring the airport altitudes. Now I have to figure (pun intended) out how to do it!

You didn't address my query about the frequent heading changes. Some of which, it seemed to me, the controllers were actually searching for the airport.

It's strange that I have no difficulty anywhere else with the lining up. Just my luck that I use EGGD as my home airport. I suppose I could change to Exeter.

Thanks for the quick response Thomas. Sorry to be a nuisance.

John

See below (changing FAF alt), but an alternative way could be to increase the FAF distance. This can only be done globally in Options #2 -> Advanced Options -> FAF Distance. I have set it to 9 (from the default 7) to avoid similar situations without changing the FAF Alt for individual airports. Please do not change the default FAF Alt here unless you know what you are doing, but see below to adjust it for individual airports:

On the SIDs/STARs page, enter EGGD in the airport field, press Enter.
Now use the up/down arrows next to the FAF alt, and finally Save.

This sometimes happens to me if the runway changes, or if I am too close to the airport and they want to bring me back to the FAF.

With above adjustments, EGGD should work fine, except for the 26/27 confusion.

Thanks for this Thomas. I'm really grateful. I've done that, lets hope it works and I don't have to bother you again.

Incidentally, without any mucking about by me, the SID and Stars page came up showing the EGGD runways as 9 and 27 so there's a small discrepancy there.

I know the default is 7 and you've got yours at 9 but I've changed the FAF distance to 10 to give myself a bit more leeway.

I'm in EDNY Friedrichstaffen at present so you'll probably be relieved to here it'll be a little while before I get back to Bristol as I want to explore the German photo scenery a little more.

All the best.

John

John
Always make sure with any scenery that you update PF3 from makerwys
And of course the scenery itself should concur with the charts.

It seems I'm not the only one experiencing poor approach information. Bobsk8 has been writing too. However, I've been given a tip fromanother forum that Vlock should be switched on. Something I've never done but I think I'll try it and see if it helps.
