[REPORTED]Not accurate starting procedure

[Birko]

Wish I knew owt about engines besides suck squeeze bang blow :D

[BIGNEWY]

Acording to spit manual, spitfire quiped with merlin 66, pilot suposed to move cut off lever forward before priming and cranking is not working in DCS. It is impossible to start DCS Spitfire this way,which simply cancel claim that DCS is accurate simulator game. PLS fix this

 

Hi I will look into this.

 

Can you show me where in the pilots notes it says to move the cut-off lever forward before priming and cranking.

 

thanks

Thank you for looking into this BIGNEWY :thumbup:

Hi all

 

I have reported this to ask the question to the team, when I find out I will feedback to you all.

 

thank you

Hi all,

 

I have a reply from the team and a spitfire pilot.

 

Our startup is correct for our spitfire.

 

Merlin 66 Bendix Stromberg carb idle cut off and then to auto rich once engine fires.

 

Thanks

[Birko]

I'm looking through the pilot's notes scratching my head now, you'd have hoped the 3rd edition didn't still have such a glaring error if it's meant to work otherwise.

 

Thank you anyways

Can I just reanimate the horse for just another little beating?

 

A real Spit could start the DCS way, many thanks for getting through to the team and a real Spit pilot and confirming that for us.

 

The issue wasn't explicitly that the DCS way maybe shouldn't work (and now we know it does), but that the pilot's notes way maybe should work.

 

Would a RR Merlin 66 with a Bendix-Stromberg carburretor in a Spitfire LF IX refuse to start up if the idle cut-off was in RUN before priming, ignition and start?

 

I'm very interested why, or why not.

 

Alright you can consider that horse black and blue :lol:

You will flood everythin with fuel when you move idle cut off lever fully forward but only when fuel booster is ON, moving this lever before priming and cranking should not interrupt starting of the engine when fuel booster is OFF

First combustion in this engine is from fuel injected by the primer, there is no way that engine would pick up that easy on carb alone when it is very far from intake manifold, Engine should at least start from primer fuel and carb should pick up later even when cut off lever was moved forward too early.

0:28 I can see that idle cut off lever is forward before priming and cranking in this spitfire

Ask team does their spitfire starting up with fuel booster ON or OFF

maybe this spit has p-51 fuel system swap

I know that's how I used to get my monster exhaust flames :D

 

At least when I figured out the tank booster was a switch on the left and not the fuel pressure cock :doh:

[grafspee]

After i though about this, i think both ways should work, i don't see any obvious fatal move that engine would not fire.

Except for the fact that aforementioned Pilot's Notes chapter IS for Merlin 66/70/266 Bendix Stromberg carb variants.

 

Also, so far, there seem to be three vids on YT, where lever moved forward before startup can be spotted:

 

a) the old one with Mk IX No. MH434, engine version - probably -63 if the current owner's website can be trusted:

 

b) Swedish Mk XVIe RW386, -266 engine:

 

c) Canadian Mk IX TE294 already posted above, rolled of the factory with -70 engine, haven't found what unit it has under the hood nowadays

 

BIGNEWY, if the people you asked start their real plane "the-DCS-way" and it works, then fine, it's a [NO-BUG] from their point of view, that's not an issue here.

 

However, for me it's clear that the other method, as per Pilot's Notes and vids above should work as well IF the DCS Spit is indeed supposed to simulate -66 engine with Bendix-Stromberg carb. If it doesn't for whatever reason (and two Open-Beta versions ago when I last tested, it still didn't), then there is a [bUG] to be looked into.

Good morning all,

 

After speaking with Nick Grey we have added this for improvement on the spitfire.

 

I cannot give a time frame currently.

 

Thank you for all of your input.

[Birko]

Thank you, good news :thumbup:

Nice to see some push on the warbirds (or at least now in the open air) getting some fixes/updates from community requests

No time frame needed for me, i feel like its already here :)

[Art-J]

BN, thanks for your help. Getting it on the list of features to be added is already a step forward.

[BIGNEWY]

No problem, we are always happy to look and evaluate with any issue.

 

Thanks for caring enough to raise the concern.

MA MAN! :)

[Mosler]

Good news, im not an expert but maybe it should be like in this video?

[saburo_cz]

It seems that both methods are correct...

 

This start-up procedure is from "Rolls Royce Merlin Maintaince Manual_Ser-66, 67,70,71,76,77, 85", October 44.

 

and here is another video showing the opposite :)

[Art-J]

Great finds, thanks for these :D.
