It has Heathrow and Birmingham about 90 minutes away and of course Cardiff and Exeter quite close. It has a lot of competition.Reg Bristol airport, it’s in the south west and has no other nearby competition, that’s why it’s a 9million pax airport, we are talking about the city of Leeds and west York’s and look what airport we got, sort the runway out,end of!
You are a bit like a stuck record on this aren't you? The runway is not ideal and it is located at an airport which is also not ideally positioned but it is what it is.Reg Bristol airport, it’s in the south west and has no other nearby competition, that’s why it’s a 9million pax airport, we are talking about the city of Leeds and west York’s and look what airport we got, sort the runway out,end of!

Yes the runway direction is relevant and no displaced thresholds at Bristol plus a lower altitude above sea level all make the difference.
AMSL is LBA 681 feet, BRS 622 feet.there is not much in it
T/O (TORA)
LBA - 2113m/2190m
BRS - 2011m/2011m
Landing (LDA)
LBA - 1524m/1620m
BRS - 1623m/1566m
reg white heathers point about moving the touchdown point further back to the start of the runway so aircraft land earlier, so say around 300-400metre back, would aircraft really be that much lower when coming into land, can anyone roughly calculate how much lower?
Yes, just a silly typo, sorry fight2win. The glideslope on runway 32 is current 3 degrees, and on 14, due to the Chevin clearance required, it is 3.5 degrees, which is one of the reasons we don't have Cat 3 landing on that runway.do you mean pre 1984? whats the current glideslope degree for runway32?
Hi Karfa, I’m slack as a bag when it comes to technical stuff, but I assume the angle is too high to pick up the beam therefore renders it inactive?
Exactly KARFA. Solve one problem by effectively providing a longer stopping distance on 32 landings, but create a new one with no Autoland capability, which is hardly the best idea at the UK's highest airport. And, all at huge cost. It would only be worthwhile if the glideslope remained 3 degrees but aircraft would be considerably lower when passing over the Scotland Lane estate as they would then be touching down pretty close to the end of the concrete. I wouldn't mind that at all, but I can imagine that those who live there, just might. Even if their objections were over-ruled, there remains the problem of completely revised approach lighting, runway lighting and changes to the ILS system, meaning major disruption for the airport with the high risk of flights unable to land whilst all this is going on. Given that the MAN black hole is where it is, and likely to continue sucking in the vast majority of longer haul flights, it is hard to imagine the business case stacking up for doing all of that in the perhaps vain hope that LBA might secure a few long haul flights - and bearing in mind that both the Boeing 787 and Airbus A350 can operate long haul, and, according to LBA management and ATC, operate from LBA as it is.You can have an ILS at 3.5 degrees but only at CATI level. You can use the autopilot to follow the ILS down but the landing itself would have be hand flown. I understand CATII/III level ILS (i.e. autolands) are not possible at 3.5 degrees or more. Loss of autoland for 32 due to increasing the glide slope angle would be a very big issue whenever we have low visibility at LBA
