Engine flame-outs with Rick's Andover C1

kit · Post by **kit** » 11 Jan 2007, 00:25

The VA of which I'm a member, Albion Air Cargo, have adopted two of Rick's HS780s into our vintage period 'Albion Airways' fleet, with a view to using them on our Far East freight routes.

In the 'true realism' sense we decided to fly both of them out there on-line under IVAO, but both of us have only got as far as Northern France............. :k:

The problem is that we can't keep the engines running for long enough. After about 10-15 mins at cruise altitude (FL190) first #1 shuts down, followed by #2 after a few minutes. The first time it happened to me I made an emergency diversion to Shoreham (!) and the second occasion I made a glide landing into Rouen.

Various of us have read the manual till we're blue in the face but can't figure out what we're doing wrong. If I try a re-light using the procedure in the manual the engine catches fire too, which is a bit nerve shattering!

Has anyone else experienced this or better could anyone point out what must be an obvious mistake we're making but not seeing?

Engine de-ice & fuel filter heaters

Also only use max power for 5 minutes only. Set 14,200rpm shortly after takeoff and leave it there until you start descending. Use the fuel trim to maintain a max ITT of 755'c for the climb and 730 for the cruise.

You shouldn't have any problems if you do to the above. I recently flew a 6 hour sector with no trouble.
Hope it helps.

Oh dear Kit.. a tale of woe if ever there was one!! :roll:

Do you fly Rick's 748 (or have you flown Rick's 748) and have experienced the same problem?? I've flown the 780 on 21 occassions for our VA and have never experienced a problem with the aircraft so I guess there's something you've not read. I fly the 780 in exactly the same way I fly the 748 (with the expection I give it less than full throttle on takeoff) and follow the pull-down checklist.

Things to look out for.. Fuel Heaters.. If you suspect you are going to encounter air temps of less than +5C.. turn them on.

DO NOT rev the BLX off the engines. Use takeoff power for a max of 5 mins (though this shouldn't be necessary.. especially flying from the UK) then reduce throttle to Climb/Cruise (one and the same.. 14200rpm).

Make sure your engine heating is on 'as required'.

That really is about it. By following the interactive checklist and adjusting fuel trim to achieve the correct temps.. you shouldn't have anything else to look out for. You can.. straight out of the box.. fly this aircraft under normal circumstances without any problems as long as you don't run at max rpm.. this without even looking at the checklist. The easiest way to break it is to run at full throttle for too long and you will break it

Thanks gentlemen for the swift response. I'll pass your hints back up the line and we'll have another go.

That is when we've shipped some new engines over to France plus the Groundie team to replace them...........

I've only flown Rick's 748 for a very short while Dave, probably not long enough to exhibit the same problem, but I'll do so now, if only as a training exercise!

Hi Kit..

Good luck

If you have the 748 mastered, you will have no problem at all with the 780 (and vice versa). You'll notice the additional power of the 780 on takeoff as well as a higher cruise speed but otherwise, there's little to choose between them. Notwithstanding their fragile engines if pushed too hard for too long (though the book says 5mins max, you'll get between 10 and 15mins grace on the model before the damage is irrepairable).. both the 748 and 780 are the most viceless, docile aircraft you could want to fly and are very capable VA performers

Ive only really got going in the 748/780 when FSCargo 1.2 came out with support for larger craft
