Classic British Flight Sim

Hi Guys,

Here's one for you.

Trying to fly my booked flight from Teeside to Jersey (flynet) with Ricks trusty Viscount, at around FL150 one by one the engines wind down. I have all the deicing on, and after restarts the autopilot keeps demanding a pitch up and I need full deflection to even try to control the inevitable stall.

Any thoughts please?

Thanks

I don't think the autopilot on these old aircraft are as capable of recovering a situation as the modern ones are.

You have to pretty much stabilise manually it as you want it then select the autopilot

Are you turning the AP off getting control and stability back then re engaging?

As to the flameouts if the heaters are OK is that a fuel trim problem?

Garry

Off for a test flight to check but the fuel was trimmed ok. It just did not want to recover despite my best efforts.

I wonder if it is because I am also online? If I use real weather FS9 crashes.

Will investigate and report back.

Thanks Gary.

Hello mate..

Being online shouldn't cause a problem but as this is happening at around FL150, I'd suspect (as Garry does) that it's a heating problem. In reality.. you can get away without fuel trimming (on the model if not in real life) so my first suspect would be no Puds on. I rarely use FULL anti icing as I don't fly in weather to warrant it. Fuel heaters are only on as required and would normally be off during taxying and in flight.

It really does sound like a heating prob but if you're flying to the intuitive checklist.. you shouldn't really see one :think:

Scorpius,

I am just finishing a flight in a V800 and I have had a thought. If you are using Fraser McKay's panels then you need to check your fuel filter heating.

What springs to mind is that you have turned all of the heating on in the overhead panel, however have you switched on the fuel filter heaters? These are the row of four switches at the top right of the Starboard Sill panel, (up for on).
The starboard panel is acessed by clicking the arrow pointing to the bottom right, in the view switch area.

I may be totally wrong and if you have these switched on then please forgive my assumption but these have caught me out a few times.

Cheers

Depending on the marque you are flying, the filter heaters are as described on the 810 but on the overhead on the 802/806. The latter models are also connected to the central warning system, so if you do have a filter blockage the associated red lamp will light and the CWS master on the coaming will flash. Power unit deicers are not connected to the CWS so there is no pre flameout warning, but a drop in torque and JPT will be noticed first

cheers

Fraser

Thanks for all the advice guys. Did the test flight, no problems although I did increase the climb speed to 160 kts.

Could have well been a fuel blockage, will keep an eye out on that one.

Once again, thanks to everyone who contributed.
