    Default Main Force Sample Flight-Plan and/or Nav-Log

    Hello All,

    I am trying to reproduce a Main Force sample flight-plan for use in some experiments, using FSX, on some WW2 bombing raids.

    I thought this would be easy! Wrong! I have just spent several hours interrogating the internet looking for some information. I found many fascinating websites (as one does!) which side-tracked me, but nothing on which I could build a flight-plan.

    The plot was to “fly”, say, a Lancaster (or Halifax, or Wellington, etc,) from Lincolnshire to, say, Southwold, then to several places in Germany, and return via north France and Beachy Head to somewhere 3 Group-ish*. This would seem to be a fairly bog-standard type route? I was looking for some sort of representative figures for speed, rate-of-climb, etc, after take-off. What height(s) did they cross the UK coast outbound? What height(s)/speed(s) did they cruise at? What height(s) did they bomb from? What height(s) – in a, now, much lighter a/c – did they cruise back at? Where did they start the descent procedure? And so on!

    I am aware that most of the answers will be the same as “how long is a piece of string?”. But some very broad-brush pointers in the right direction would be welcomed. I try to use the ‘Monte Carlo’ system. I start with a flight-plan, “fly” it, and note the results. Then I slightly change one (or more) of the parameters, “fly” it again (and again, and again), and note any changes. Changing the Forecast/Found winds, for example, is one experiment (This, I am aware, is very dangerous ground.) But if you don't play with the figures, with absolutely no danger of bending real blokes or a/c, how will we 'push back the frontiers of science?' I am simply trying to understand (and/or quantify?) the difficulties that my Met predecessors, and their 'customers', had to deal with!

    TIA (or tia – as the case may be!!!)

    * My FSX won’t let me “fly” a pre-planned route back to the departure a/f. Don’t know why.

    Peter, Are you still looking for flight plans etc? I have some from 75 Sqn where most of the navigation data entered in the nav log is GEE coordinates, but some info would be usable. Let me know if I can help. Regards, Terry

    Terry, Hi,
    Mni tks yr response, and offer. However, the flt pln that Richard emailed me is exactly what I was after. It gave precise figures (kts, feet, IAS, etc) and locations (lat/lon, geographic, etc) for one raid. They won't all be the same, obviously, but they turned out to be very much as expected. I now just have to 'make' my "a/c" replicate them when I "fly" it!!
    Appreciate yr offer of help!
