Examination of Witnesses (Questions 80-99)

AIR VICE-MARSHAL SIMON BOLLOM, AIR VICE-MARSHAL STUART BUTLER AND AIR VICE-MARSHAL CHRIS NICKOLS CBE

6 MAY 2008

  Q80  Robert Key: Or in a restricted area (temporary) under Article 96 of the Air Navigation Order 2005, but what is the difference between a restricted area (temporary) and a temporary segregated airspace, TSA?

  Air Vice-Marshal Butler: For all intents and purposes of flying a UAV, nothing.

  Q81  Robert Key: But technically what is the difference, please?

  Air Vice-Marshal Butler: Simon, is that something you have got?

  Air Vice-Marshal Bollom: I do not have that.

  Air Vice-Marshal Butler: I am not sure we have it to hand. We can get back to you, but for the purposes of flying the UAV, to us, the area restrictions are the same. We have to observe the same sort of safety regulatory regime.

  Q82  Robert Key: I would be very grateful if you could send us a note saying what is the difference because in their evidence to us the CAA refers to these zones as restricted area (temporary) but others, including QinetiQ, talk about temporary segregated airspace.

  Air Vice-Marshal Butler: Again we will write to you but I am pretty sure they are talking about exactly the same thing. [8]

  Q83 Robert Key: The real problem with all this is that a single-engined beast like UAV could drop out of the sky and with luck it will glide, but it may not be lucky. There have been a number of problems with these, in Israel of course and elsewhere, so how do you assess the risk of UAVs failing and falling out of the sky?

  Air Vice-Marshal Butler: Of course the air worthiness regime that we go through for UAVs is the same airworthiness regime that we go through with an ordinary fixed-wing aircraft. The sorts of failure rates on a UAV that is designed to the same standards as, let us say for example a single-engined light aircraft, are very, very similar, so again the element of risk there is one associated with a Cessna 150 or any light aircraft which again is single-engined.

  Q84  Robert Key: And at the moment the only place where UAVs are being trialled is down at Aberporth I think?

  Air Vice-Marshal Butler: Indeed that is where we are tending to do the majority of the trials although we have done trials elsewhere. In fact, the earlier maritime investigation that I referred to was done up in the north of Scotland.

  Q85  Robert Key: But given that the Royal Artillery is going to be training the Army in how to use these things tactically, the Salisbury Plain Training Area is the favoured place, and I have to convince my constituents that there is not going to be a problem with UAVs buzzing around, which of course they cannot see and they cannot hear but they know will be there. I gather that at the moment the Civil Aviation Authority has not come to a satisfactory agreement with the Ministry of Defence. How long do you think that will be because we know that Thales has told us their contract is absolutely bang up-to-date and that is fine but if they are not allowed to fly these things, is this going to mean slippage for our Forces?

  Air Vice-Marshal Butler: There are a number of things we are doing and we also have fallback options in both cases. We would like to operate it in Salisbury Plain because in terms of routine training that is clearly the best place for us to do it, that is where the Army units are operating. However, we have to go through the same CAA regulatory regime that we would for any other aircraft. I referred to Danger Areas but what we mean is an area of restricted airspace where we can fly the UAV. However, we do have fallback options and, in the extreme, for example, there are a number of danger areas in the US that we could use. Clearly that means that we will not get quite the standard of training, certainly on the routine side, that we would do back at Salisbury Plain but we do have fallback options should we be required to do so. Salisbury Plain is pretty critical because we do need to, as best we can, fly it on a routine basis when the Army are operating in Salisbury Plain, and that is where they do their routine training. So we have a fallback which will not be as good but again I emphasise that we have to go through the same regulatory regime with the CAA that we would with any other request for a change in area and we are doing so at the moment.

  Q86  Robert Key: I understand that and I am very grateful on behalf of my constituents who will be much reassured and that is all very well, but we are using UAVs currently in Afghanistan and Iraq so actually we are saying it does not matter if they drop out of the sky on top of Afghan people and Iraqis?

  Air Vice-Marshal Butler: No, that is not true either. We have gone through an airworthiness regime to fly any air vehicle in any country, and we have to get clearance to do so, and we go through a fairly strict regulatory regime. It is all weighed off against the risk and also the circumstances in which you are flying them. Again the risk rates for flying your average UAV are broadly similar to a single-engined light aeroplane so they are not that dissimilar.

  Air Vice-Marshal Bollom: Just to reinforce the point, for military aviation we tend to operate in terms of probability of injury somewhere in the order of 10-5 and in putting together the safety case for Reaper, and indeed for Watchkeeper, we are operating in exactly the same regime and you take account, as my colleague has mentioned, of a whole range of factors. It is not just how you design the air vehicle and how it is produced and maintained; it is how it is operated and the sorts of areas that it is going to fly, so that is all done very rigorously in the same way that we would with a manned vehicle.

  Q87  Robert Key: Are you between you, three distinguished Air Vice-Marshals, part of the assessment of the use of autonomous vehicles in general in the military sphere?

  Air Vice-Marshal Butler: Can I just say that the safety case for a particular platform is led and owned by the Service that operates them, but what we do have to have is an independent safety adviser who will look at the safety case that we put forward and provide advice back to us.

  Q88  Robert Key: Of course it is not just the military, Chairman, who will be using these vehicles, we already know that a number of police forces are trialling them, and this does lead to whole new areas of risk that have to be assessed within the civilian community, let alone the military because there will be civilian applications, and people are thinking about this, I hope?

  Air Vice-Marshal Butler: Yes, as I say, we have a very strict regulatory regime for flying UAVs, exactly the same as we would if for example we procured a new single-engined light aircraft. We would have to go through the same regime there and the standards are very similar.

  Q89  Robert Key: If a UAV does fall out of the sky, who will be responsible for any injury or death caused by that system?

  Air Vice-Marshal Butler: I would have to come back to you on that one.[9]

  Q90 Robert Key: I wish you would, please.

  Air Vice-Marshal Butler: Because again it is not simple. It depends on where it is and who it is being operated by.

  Q91  Robert Key: It is why I asked the question.

  Air Vice-Marshal Butler: Yes of course and again we can come back to you on that one.

  Q92  Mr Havard: You could use them in the area of Salisbury Plain now as long as they are within that area. The argument, as I understand it, is having to come out of that current area in order to use all the stand-off capability for the machinery; is that right?

  Air Vice-Marshal Butler: That is correct.

  Q93  Mr Havard: But we have training areas in BATUS in Canada and Hungary and so on; I presume there is no difficulty in using them with joint training there, is there?

  Air Vice-Marshal Butler: No, it is simply a function of size. Because the capability you have with Watchkeeper requires a much greater standoff distance for you to get the full impact of the sensor, Salisbury Plain Training Area is simply not big enough. It was for Phoenix but it is not for Watchkeeper. BATUS, as you know, is a much much bigger training area so hence there is not an issue out there and of course it is a permanent Danger Area.

  Q94  Mr Havard: It is just you mentioned the United States of America but you did not mention these others.

  Air Vice-Marshal Butler: There are a number of these around the world. There are quite a lot in the Middle East as well for example so there are a number of areas where we could use them should we be required to do so.

  Q95  Chairman: Getting back to the allies question, the NATO Joint Air Power Competence Centre has said that the integration of unmanned aerial systems is not occurring in NATO and, "Nations are developing stove-piped systems that do not integrate with each other nor with NATO networks." Do you agree with that?

  Air Vice-Marshal Butler: To an extent yes but largely no. We go through a number of systems, as I was mentioning earlier, on the bilateral side but also on the international side initially at "5-eyes", we do some at "7-eyes", some at NATO and some of the coalitions of the willing and it really depends on how we are looking at it as to how we integrate UAV systems. For example, the data that we provide from Reaper goes into a central collection centre in Al Udeid in Qatar as it happens and that information is used by almost every nation within the coalition. It is quite frequently transmitted on individual nations' transmission systems or on a NATO system, for example, but it is available to the vast majority of the coalition so in that sort of case it is very simple. It is transmitted where it can be, but there are a number of issues. I will be perfectly honest, when you have a UAV transmitting data down to the ground on a direct line, for example, you need the correct receiver at the bottom, so what we need to do as part of the planning process is make sure the UAV that we are flying in a particular area suits the particular troops that we are supporting, which again is more of a planning issue of the "direct" bit of the DPCD cycle, so in general terms it is pretty good but I am not under-estimating the challenge there. Unfortunately, in terms of the balance of investment, you have to hang your hat somewhere and there are a number of NATO standards which we always conform to. There are a number of interfaces which we recognise we have to make work and again we do that at a variety of different international fora to try and make sure we get the best from what we have got available.

  Q96  Chairman: I think the answer you gave about the dissemination of the data across different countries was aimed at the second `D' part of the DPCD whereas what this report was referring to was the `C' part, the collection, and there are lots of different types of UAVs none of which seem to be compatible with each other.

  Air Vice-Marshal Butler: Indeed, but again I will refer you to one of the things we mentioned to one of the earlier questions and that is the fact that the focus of all of this needs to be where the information is being delivered. To a soldier on the ground with his laptop who is receiving his picture, he does not actually care whether it is Reaper or whether it is a Watchkeeper or whether it is a Canadian system or an Iraqi system; he just wants his data, so providing the standards work, it does not really matter.

  Air Vice-Marshal Nickols: It is just worth making the point for instance in Afghanistan an awful lot of the UAVs are either Predator As, Reapers or Hermes 450 and the same ground terminal will accept the imagery from all three of those, whether they be UK, US, or indeed any other nation, so while there are still some problems with some systems we are tackling it and addressing the problem, particularly in the operational areas.

  Q97  Mr Crausby: Some questions about future ISTAR capability requirements. What ISTAR capability is the MoD seeking in five years' time and could you say something about weaponisation as well with regard to the UAVs over that period and what issues will arise from all of that?

  Air Vice-Marshal Butler: We are constantly keeping the ISTAR capability requirements under review. There are a number of systems which we currently have in the plan on which we could certainly send a note to you but I would not want to discuss it in open session. Regarding the arming of UAVs, I think there is a declared open intent that we will arm Reaper. We do have clearance to do so from the US and it will be carrying the Hellfire missile largely and a small bomb. Outwith that there are no current plans, but we are constantly keeping our requirements under review and that does not mean to say that it will not be so in the future.

  Q98  Mr Crausby: Can you say something about the speed of technology change as well. Are we not in danger of technology changing so quickly that by the time these things are ready they are over?

  Air Vice-Marshal Butler: Not really. The change in technology of the platform itself is not that rapid. It has been and if you were to draw a graph of how the technology has gone, it has gone very steep but now it is starting to level out because we have got to a point where you can largely build it faster or bigger or smaller, so it is not a giant leap in the technology itself. The only additional bit I would add to that maybe is the advent of the unmanned combat air vehicle where we do already have some research, as you will be aware, under the Taranis programme with a consortium led by BAE Systems looking at the unmanned combat air vehicles, so there are some advances to be had there because it deals with different requirements to the UAV but largely we are there with standard UAV platforms.

  Q99  Mr Crausby: What about specialist personnel, how is the MoD ensuring that we have the right levels? Is this an area of concern?

  Air Vice-Marshal Butler: It is. We are learning very rapidly by operating the systems that we have. The Army for example are very familiar with operating with a tactical UAV because they have done it with things like Phoenix for some time so it is no giant leap for them. For the Airforce it has been because we have been getting into an entirely different way of doing business. We have learned the lesson very quickly over the last year or so and we now have a better understanding of the type of person that we need and we are making sure that we have got a future plan to generate that type of person.
