wep on RAF planes awol???? boost levels??? no 100 octane fuel:(

You guys are nuts! Have fun crunching the numbers though, if that's what floats yer skiff.

either way, all the RAF planes performance is down on what it should be below 16,500ft.

where's the 100 octane fuel....

Incorrect Boost indications and Boost Cut out mechanisation was been brought up before release. The developers are aware of it.

Are they aware of the incorrect top speed of thr mkI models?

I saw this command in another thread...

186 = thtl_psicutout

I assume that is the Boost Control Cut Out that would allow the pilot to obtain max boost. Is that different from the legacy Il2 WEP command? I'm not sure if that command is bound by default or what it does in game. You see, I'm in North America, so I have to wait for you guys to finish beta...

The concept of boost Cut out is similar to WEP but different

Here is a simplifed description of how it works.

Most RAF/Luftwaffe aircraft had Boost controllers (Most US aircraft at this stage didn't). With Boost control engaged (the norm) the pilot selects the required Boost then as he climbs or descends the Boost controller holds the selected Boost constant without any further pilot action required (below Full throttle height FTH)

In a no Boost controller aeroplane the throttle would need to be progressively opened as you climb until you get to Full throttle height (FTH).

The second function of the boost controller is to limit or "Boost protect" the engine to a rated limit. So the pilot can select Full throttle knowing he is not going to "overboost" the engine. If not equipped with a Boost controller then the additional pilot workload is required to ensure that Boost limits are not excedded.

Boost cutout simply resets the Boost controller limit to some other value above normal rated Boost. In the case of the Spitfires Rated Boost for the MKI, 1A was +6.25Lbs, with MKII at +9lbs. In all cases once Boost Cutout is selected (in the case of the Spits pushing the red boost cut out lever forward and selecting full throttle) will give you +12Lbs boost up to the respective FTH (about from memory 10,500Feet). If desired the pilot could then rotate the Boost cut out switch back (cant do this at the moment in COD on the Spit .. it should be a toggle control). Once done the Boost controller is back using its normal +6.25/+9Lb limit. In the case of the Hurricane the Boost Cut out was a plunger arrangement which works correctly as a toggle in COD. However no change in Boost is evident on the boost gauge.

Its also worth pointing out that at the time of BOB most Boost gauges didn't go up to +12Lbs so Boost cut out (Below FTH) would result in Full scale Boost deflection.

Running at +12lbs brings with it additional cooling and engine wear problems.

As others have stated +12Lbs Boost was only possible if 100 Octane fuel was being used. Its fair enough to state that all operational RAF fighters were running 100 octane fuel during the battle.

So this area needs to be tweaked.

So yor saying that normal full throttle boost in thr mkII should be +9lb and +12lb when opening the boost gate? As of rigt now its only +9lb AFTER opening the boost gate....

Also what is the point of the mkIa in this sim? I cant quite figure it out... If the prop pitch in the mkIa isnt a bug then what makes it any different from the mkI (besides the fact that it has a slower top speed)?

Are the devs aware that the propellers and nose cone of the mkIa in game are those of the Rotol CSP unit?

Thanks for the explanation IvanK. Is my understanding correct please?.....

The boost controller (limiter) will only hold the boost constant (at rated boost) if a throttle setting is selected which would exceed that rated boost. If I select a lower boost value like 3lbs in a climb, the controller won't feed in more throttle to maintain that value will it?

I think what I'm trying to say is that the controller is only capable of maintaining a boost value by reducing throttle input, not by increasing it.

Does that make sense?

Thanks

are u kidding me? I've logged about 14 hours now! (so Steam tells me) I LOVE this game..err sim... the spit is a joy to fly... alot of it is very "real" feeling...

its exactly like the pilots say "hurri is a much more stable gun platform" and the spits controls are "telepathic"...

believe me Im having a WONDERFUL time!
