Select Committee on Environment, Transport and Regional Affairs Minutes of Evidence


Examination of Witnesses (Questions 60 - 80)

WEDNESDAY 8 NOVEMBER 2000

MR IAIN FINDLAY, MR ANDY MOONIE, MR ANGUS MACCORMICK, MR LAURENCE KING AND MR NICK EWING

  60. Will it all be working on the date that it is brought into you?
  (Mr Findlay) Not all the equipment will be there and available. I will pass you to Nick Ewing to answer that.
  (Mr Ewing) There are approximately going to be about 40 changes to the system that will not be put on to the system prior to `O' date. It has been considered by the members of the NERC training team, that they are not safety-for-operational impact, with those not being on the system, they are fundamentally to enhance the system and make the job easier for the controller.

  61. The transfer is to be done in January because on the whole traffic is much lighter at that time of the year. By the time the traffic builds up in summer will the system be able to cope with the build up of the traffic?
  (Mr Ewing) The idea is that you gain experience during the quiet time of the year, although it is not particularly quiet in January and by the time you hit summer levels of traffic you would have gained enough experience to handle the requirements.

  62. While this is being introduced what is happening about the safety regulation group? Has that been given a back number or is the safety regulation group operating as effectively in this transfer period?
  (Mr Findlay) The safety regulation group will be under a great deal of pressure, I am sure, to actually bring Swanwick in on time. I am also very clear that those people that are in the safety regulation group know what safety is about and they will make sure that the system is as safe as possible at that point.

  63. In the whole transfer process you told us earlier that they were probably 50 controllers short. Is there going to be a real difficulty in doing the new training and maintaining the system?
  (Mr Findlay) Yes, without a doubt there will be problems in that area. It is a major task to actually keep a system working, together with training people for a new task.

  64. Given the time likely to train the people, that shortage is getting pretty critical, is it not?
  (Mr Findlay) Yes, it is a critical shortage. There is a shortage—not that it helps us—throughout the world of air traffic controllers. It seems there are not as many people nowadays wanting to become air traffic controllers.

Chairman

  65. I cannot imagine why. It is such a nice job, so relaxing.
  (Mr Findlay) It is relaxing, easy to do. People are not applying in the same numbers as before.

Mr Bennett

  66. What are you as a union doing to encourage people to apply for the jobs?
  (Mr Findlay) We are trying to ensure that as many people as possible know about air traffic, know about the job. We, in fact, promote air traffic throughout the world as a good job and, in fact, as a task that is very essential.

Mr Olner

  67. I wonder how aware your members are of the new arrangements put in place by the CAA to deal with the NATS after the PPP?
  (Mr Findlay) As a union we look after the CAA and that actually comes as a surprise to me. I do not know of any new arrangement. I think one of the things that people think is that the separation of the CAA and NATS is something new. In actual fact, what has happened over the years is that NATS and the CAA, the safety regulator, have been at arm's length.

  68. That is right, though, that is how it should be.
  (Mr Findlay) We have no qualms about that whatsoever. What we have said is that the CAA comprises not only the safety regulation group but the economic regulation group as well. We, as well as NATS, are at loggerheads with them because of some of their ideas.

Chairman

  69. I want some fairly sharp answers. Near misses and the loss of separation, how many have occurred during the various periods of computer failure this year?
  (Mr King) Certainly with regard to June 17th—I cannot tell you about some of the others—we have no information that any losses occurred that day. That is not to say there was not an increase risk of such occurrences happening within such unusual circumstances. As for overall totals in other days I do not have that information.

  70. Is that because you would get that, in a sense, in arrears, you get that after the event?
  (Mr King) In total numbers, yes.

  71. How many commercial aircraft have opted to fly in uncontrolled airspace during computer failures at LATCC because the pilots get fed up?
  (Mr MacCormick) I do not have any information on that. I know there were some.

  72. There is some anecdotal evidence. What we need is some indication as to whether this is anecdotal or whether there is something actually happening. You are not aware of that?
  (Mr King) Aircraft did leave controlled airspace, as they are allowed to do, and work with other operators, probably the military, to take short cuts to avoid further delays. In terms of total numbers we do not have that information.

  73. What pressures are going to be put on to the system if there is delay over the New Scottish Centre?
  (Mr Findlay) That, of course, would be a major problem because the New Scottish Centre is designed to expedite the airspace that is available and with new technology it would be much more helpful to have that Centre in place. It would cause delay.

  74. Can I just ask you one thing, Mr Findlay. You know that this project has been badly handled in the past and you now tell us that it is under control. Are you confident, not as an engineer dealing in IT but as someone responsible for air traffic control, that the bugs in the system are now going to be ironed out so that when this system finally comes on stream and when Swanwick is ready and fully operational, it will be possible for the air traffic controllers to provide the high level of care that we expect?
  (Mr Findlay) Absolutely, because our controllers and engineers would not let it work if there were still bugs in the system.

  75. Does that indicate to you that there is at least a possibility that the system may not come on stream on the date at which it is expected?
  (Mr Findlay) No. There is always that possibility because there may be a bug so big that it is safety critical and, therefore, it will not be brought on stream.

Mr Bennett

  76. Between now and then are we going to have another problem like we had on 17 June, or is the present system going to be robust enough to get us through to the new one coming in?
  (Mr Findlay) We could have another problem. It may not be the same problem because I think that has been fixed. Yes, of course there could be a problem.
  (Mr MacCormick) We did have the same problem last weekend, I understand, twice it happened, although not to the same extent. On late Friday afternoon the computer was out for 20 minutes. That did not result in much delay, especially compared with the 17th. I understand while trying to repair part of the computer on the Saturday evening it did not start properly until the Sunday morning and precautionary flow control was put on and there were quite extensive delays on Sunday morning last weekend.

Chairman

  77. This is a completely different pattern from the pattern we have expected in the past, is it not? We did not expect routinely to have a number of failures. We are not in the winter as well, we are not actually talking about what would be regarded as the high peak traffic.
  (Mr MacCormick) Anecdotal evidence, again, amongst controllers is, I understand, that these things are related to new patches that have been put on to the computer associated with the Swanwick system.

  78. What you are saying is that the old system coped perfectly well hanging together with string, until somebody came along and got the extra money, which this Committee asked for as well, I have to say, to upgrade the system and what is happening now is that the extra pressures being put on the system are resulting from time to time in glitches which are not only holding people up but are causing real delays?
  (Mr MacCormick) I am not a software engineer, I could not—

  79. Since we are dealing in anecdotal evidence, Mr MacCormick, what are you telling me? Are you saying to me that the old system more or less worked and now you are not sure it will do because the pressures put on it are too great? It is all right, no-one is going to prosecute you if you are wrong and they certainly will not prosecute you if you are right.
  (Mr MacCormick) My personal feeling is that I am satisfied with the computer, I have used it for ten years at Heathrow very successfully. In actual fact, if you look at the capacity of the overall system we have actually gone up 49 per cent since 1989.

  80. On the old system before anybody started mucking about with it?
  (Mr MacCormick) Absolutely. That is what the New En Route Centre was designed to cope with and we are actually at that level now. My personal feeling is that you tinker with something that you are a bit uncertain about -I put a new programme on my computer and it does not quite work properly—and, as we said earlier, it is very, very difficult to 100 per cent test that.

  Chairman: On that note of unalloyed joy can I thank you very much for coming. Thank you, gentlemen.
