    Point taken on the flap. The earlier Lear’s I used to work on needed a lot more flap for take off.

    Interesting to see how high the other pictures you listed show the aircraft with the gear still down suggesting the retraction process may be quite slow. I think the most damning item may be the reflection of the sun off the leading edge of the vertical stabilizer which would suggest the shadowing should be behind the aircraft.

    You all seem to be arguing over who does the marshalling as opposed to the name. Yes, they are called marshallers and yes, the marshalling can be done by different people dependant on where in the world, or for that matter where in the UK you are. I think only Reed Aviation (EZY handlers) have their dispatchers marshalling. Other companies hold their dispathers in too high regard and too valuable to be doing anything other than dispatching.

    Can’t see any flap extended either. Look at the angle of shadow too. Greater on the lear than the EK. Picture through the windscreen doesn’t look right either. Lear gear moves slowly too.

    It was foggy when I was in MAN today and what with an engine failure, wheel well fire, double gen failure and 2 go arounds it was all I needed. Miraculously, at the touch of a button it was CAVOK. The joys of recurrent sim sessions!

    Nice pics.

    Not sure what the 744 is like for flightdeck visibility but from the left seat of the 767/757 you can’t see the wing tip. You do develop a feeling for where the wingtip is but you are never sure. I am often surprised at how close in it is when being marshalled past an obstruction or into a tight parking spot which I guess is not a bad thing as I think I need more room than necessary. LHR has a warning on the ATIS to say that pilots are responsible for clearance in the runway holding area as wingtip clearance cannot be assured.

    Oh, yeah. Lets send several million dollars to some crook in Nigeria via a method that is completely untrackable. I just found GBP2.50 down the sofa. Anyone want to club together and get it?

    Sorry, it was 50 yds mentioned above and 170kts is about 87m/s therefore less than 0.6 seconds to cover the remaining “runway” as mentioned. At the end of this the aircraft should be at least 50 ft above the surface.

    Here’s the one showing the gravel kit and the vortex disruptors. I have a book somwhere with a picture of the engine I was thinking of. I will find it one day unless someone else beats me to it.

    Bypass jets can’t power back as there is too much air flowing through the core of the engine. Only the fan air is bypassed. All the debris and FOD would be ingested which is not a great idea. It isn’t allowed on the 75/76 at all as per Boeing limitations.

    Some 737-200’s had a special mark of engine that had an air feed around the engine nacelle to blow debris away anytime but particularly when reverse was applied. Not sure if it was for power back purposes but it was a common fit on African 73’s at that time. If I find a picture I will post it.

    If anyone is having trouble understanding my posts with the jargon used, let me know as I would rather be understood than have you thinking that rotation this close to the end of the paved surface is acceptable.

    Anyone care to work out how long it would take to cover 50ft at 170kts?

    10,000ft if memory serves me correctly.

    My point exactly WD. The rules state that on a dry runway there is a 50ft screen height that must be reached by the end of the ASDA. This is reduced to 35ft with a wet runway. As such both of these photos show that this was not acheived and the runway was dry.

    Commercial jet aviation is somewhat different to general aviation. Rotation that close to the end of the runway is cause for concern. V1 will have been a long way back down the runway and as such the aircraft must still accelerate to Vr. If they were rotating on the piano keys with all engines operating, they will not have made it with one failed, that is assuming that they did have all engines operating here. There is very little clearway on the this runway and with a 50ft screen height, there is no way they satisfied the rules here derated take off or not.
