Hi Matey

sorry wasn't trying to cause trouble but just found some better data recently whn i was Hawk book hunting.

Data could be wrong as i no longer have the stuff i used to build the Viking (still have the source files for models) but not the data stuff.

Regards
Rick

Hello mate :)

No sir.. didn't take it that way at all ;-) I knew we had next to no info at the time and what info you'd got was sketchy to say the least. If you remember.. I picked up a Valetta Pilots Notes some time after which is close but not really close enough as they don't have the same Hercules fitted :roll: I always keep my eye's open for Viking info and hoped the Airlines and Airliners book would carry a bit of tech info but as Garry said.. it doesn't. Gives a good history of the aircraft and kerzillions of COLOUR shots but nowt technical.. other than general stuff ;-)

Nice to see you're also keeping your finger on the pulse with the old girl :thumbsup:

Flew the EGBB to EGJJ route more or less using Ricks' settings. Did not adjust the MP till later in the flight so not entirely accurate. Used real weather and I used 319kg which was 11kg over the stated use. I climbed at 1000' per minute to 8000'. Cruised on the settings and got a groundspeed of about 170kts.

Did the EGJJ-EGMC training flight. Again used Ricks' power settings. Used 267kgs of fuel. Real weather and had 156-160KIAS. Gave me a 200-207kts ground speed. Flew at 9000' and climbed at 500' pm.

Hi Simon :)

TBH mate.. I think you're flogging a dead'un going as high as 9000ft unless it's to avoid weather below you or to pick up a favourable wind at that alt. Your power will drop off the higher you go and with it your TAS :cpu:

Dave B's original data will be better to fly to as thats what we had when i built the Viking.

sorry for making it more complicated :lol:

Maybe when you re-do the Viking with a suuuuuper VC that zillions will want to use.. we can use the new figures :o

I jest.. I do really :lol:

Simon..
Those fuel figures look about 10-11kg under mine mate so they're not far off ;-)

Be careful if you are using the figures against the add-on panel with the tiny gauges and the huge switchboard blocking your 1 o'clock view because if I remember rightly many of the gauges are incorrectly calibrated - including the airspeed. I don't think that panel was ever finished.

Yes, I've got the fuel consumption down, I will reduce the height. See what happens on the next flight.
