Merlin negative G cutout too quick?

Not to mention the engine cutting as you taxi out of a hangar down a tiny 6 inch slope.

Which begs the question: How ever did the a/c take off without having an engine quit at the wrong time? Airfields weren't exactly billiard table smooth.

Does it really correspond to the acceleration measured by the g-meter in the flight tests that stated a 0.1g threshold for the second stage cut-out? It is important to make sure that we do not compare apples with pears.

The maddox parameters do not tell us but I assume it is through the CoG. I have to assume that the parameters returned by the game are those used by 1C in development.

As far as I know there is no historical data to identify the location of the accelerometer used in the 1940 tests but it seems reasonable to suppose it would be close to the CoG to aviod variable components like moment arms during rotation. As a repeatable reference it may not have been necessary to measure the g figure at the precise location of the carburettor bowl if the reduced/negative G were induced gradually.

Of course, rapid rotation would create a larger g force at a remote moment arm-end than at the CoG but if the accelerometers in the 1940 tests and the 1C model are both at the CoG then they are a reasonable comparison.

As you say the devs know the answers to this, ours is really a side discussion with proposals wildy varying from "any g reduction" to "-1.5 or more". I just thought readers would be interested to know what the game is telling us.

Is there a way to show the flown z-axis g load while flying, for instance in one of the windows? Would be great to do so for flight testing.

you can use a method such as this?

just change parameters to the one(s) you're interested in

I think this is one of my first posts here, but I came to the forum for just this reason. Really enjoying Cliffs of Dover now but this is a real spoiler.

I am finding the engine cuts when taxying out of a hangar. I don't think the RAF or Rolls Royce would accept an engine that cuts out so easily that it can't even make it out of a hangar.

There has to be something wrong with it for this to be the case. I haven't read all 25 pages because I would lose the will to live, but is there any news about and developments in relation to this issue?

Cheers,

OD.

They've only forgotten to put a quarter second delay before the onset of the cutout.

...and it cuts at 0.5G instead of 0.1G
