    It displays the handling characteristics of a very primitive design and is known to be unpredictable especially on landing.
    This is a risk to any passengers and crew on board but moreso to other aircraft and passengers on the ground.
    Given a choice very few people would fly in them or fly them.

    I’ve flown on a few of them when AAL used them and would again, if I had the chance.

    The Russian visa process has gotten a lot easier the past year or so, definitely less unpredictable than it was a decade ago.

    Ah for the days when you just sno-paked over the date on your business invitation letter and typed in a new date, photocopied it and sent the photocopy to the Russian consulate.

    I haven’t been to the last two MAKS shows, maybe 2011 will see me return. I have a friend whose family dacha is quite close to Zhukovsky.

    They are doing well at present – so I don’t see anything wrong with ‘difficult’ contract negotiations for research funding – it possibly means they are trying to be focussed on channels of research and define deliverables within their development ‘road maps’.

    No, it’s got nothing to do with that. They just have a rather different (and IMHO paranoid) view of the world compared with other organisations who fund research at universities.

    Sorry, I don’t know what software tools airlines use now. Time has moved on since I was involved in all of it.

    The secret is Rolls Royce continuously pour in R&D funding back into their companies and this is the simple but effective way of staying ahead of the game.

    I am sorry to say that Rolls Royce is the one company that makes my heart sink when I see a research funding contract landing on my desk which has their name on it as I just know that contract negotiations will be “difficult”.

    Back in 1973 you see 40 ex Belgian AF F-84F Thunderstreaks parked out on Koxyde AFB along with 5 RF-84 Thunderflashes.

    A few were saved for museums or gate guards or decoy but the rest were scrapped (along with the large number of C-119 also stored here).

    So you asked about average stage lengths and I’ve found a copy of the IATA publication ‘Airline Economic Results and Prospects 1999-2000’ which, for my sins, I edited.

    Table 18 in part 1 of the publication gives some summary statistics for the various route areas we collected year 2000 data for (detailed individual airline data from the data collection was not published although you could work out figures from the ICAO Form A data which is published).

    Just to put it into context we collected data from 43 airlines which represented 49.3% of total IATA member carrier international scheduled RTKs in 2000 (revenue tonne kilometres) and added in DOT Form 41 data for 12 US member carriers that took the total representation level up to 65.5% of total IATA international scheduled RTKs in 2000.

    Anyway, back to Table 18 which gives average stage lengths for 2000 and a few key ones are

    Within Europe (total) 956 km

    This route area is made up from the following components

    Within Northern Europe 761 Km
    Within Southern Europe 932 km
    Trans Europe 1336 km

    For comparison, the average stage length for flights in the North Atlantic route area was 5,034 km and the Transpacific was 4,756 km.

    One final point is that in the industry you will find that many of the key financial/performance indicators are just a variety of ratios based on a few key numbers and that you can concoct a whole range of figures from four or five numbers.

    I used to edit an annual report which was based on an extremely detailed data collection where carriers reported cost and revenue information broken down by aircraft type, route area, type of operation, and class of service.

    Amalgamated it produced a very powerful database which allowed the profitability (or otherwise) of individual route areas (such as the North Atlantic or intra European) to be analysed.

    Your initial calculation should be based on RPK rather than ASK as ASK is available seat capacity.

    From my experience of airline economic analyses they would have a dedicated software system which was effectively a glorified spreadsheet to pull the numbers out.

    I have some reports at home which I think give average distances flown in differing route areas.

    Of course you could always go to the airline’s investor page where they publish summary traffic data. Like BA for example. Without access to CRS/BSP data you won’t be able to calculate it yourself.

    Try looking at this as it gives definitions of the various terms. Of course you have to define what a revenue passenger is…

    If the Americans are giving an Air Display at Farnborough this year you may get a Display over Blackbush instead, as they did a few years back!

    As well as the B-52 “flypast” I think the B-1 went through Lasham the previous show..
