Re: Consultative Committee Questions
Heather - thanks for the comprehensive summary. Very useful.
I take it that neither John Parkin or Tony Hallwood were at the meeting then? I guess this fits in with the story that Mr O'Leary was in town and also that some of the answers around route development etc were even more wishy washy than usual. Who was there from the airport team?
It sounds like good progress is being made with the planning process and a target date of next summer to have it up and running seems like a commiittmemnt on their part to get moving with it, if the council don't hold things up.
Regarding the runway, the plan was always for a repair job - not a resurface. Granted, the scale of repairs may have been bigger in the original plans than what they've actually managed to get done, but I don't see it as a major issue. The ability to process passengers effectively in the terminal and make a few quid from them at the same time, is a much bigger barrier to getting the airport attracting new business than the runway surface. As long as it is safe, complies with CAA aerodrome licencing regs. and isn't costing the airport a fortune to maintain, why throw money at it.
ILS upgrades are of more interest to airline execs worried about their ability to operate their schedules to time over winter. Upgrading 14 is complicated and expensive - otherwise it would have happened already. In summary, CAT2 approaches are flown automatically by the aircraft to just below decision height - assuming you have visual contact with the runway at decision height, the autopilot is disengaged and the aircraft is landed manually. On 14 at Leeds the existing 3.5 degree glideslope is too steep for the aircraft to fly down to decision height automatically, so it would need to be lowered to between 3.25 and 3 degrees. The shallower the angle of approach, the closer the aircraft will be to the higher ground on the Chevin - which poses a risk of confusing the electronics on the aircraft when the radio altimiter suddenly detects it is a few hundred feet closer to the ground than it was expecting. If the CAA approve a lower glideslope and this is low enough to satisfy the aircraft manufactures limits for CAT2, then it is a case of buying and installing the kit and repositining all of the approach and runway lighting given the 14 threshold will end up in a slightly different place. To the best of my knowledge, there is no proposal at all to change the 32 threshold. The runway is CAT3 and for these approaches you need 300m of level ground before the threshold. That's pretty much what there is now, so without a major landfill exericse, it won't happen. Current diversion rates at the airport are around 60 - 100 flights per year from around 15,000 scheduled landings, with a number of these being wind rather than visibility releated.
For a bit more on CAT2, the following on you-tube of a BA embraer 145 landing in BHX gives you an idea. You here the autopilot coming off at about 80ft.
