Yes, I'm well aware of the report. The Accusim Spit may apear to be more benign than this would indicate and there is good reason for this...
FSX makes it very hard to put in some effects because of the weather. Wierd winds and inaccurate turbulence etc etc. As you have said, FSX is for flying, not combat and so is not so good at recreating some things that may appear in combat.
I have followed the "debate" in "the other place". One of the problems is obviously with the Spit cutting with turbulence. This simply should not
THe concept of 0.1G is hard for non-aerobatic pilots to grasp. I have many times had passengers who have been scared and upset by what they have desrcibed as severe turbulence
. This decsription is in most cases (and certainly from the Airlines passengers' point of view also) between +1.5 and +0.5G.nowhere near the Merlin "cut-out" level of +0.1.
Now to give you some idea, a normal airline 20-30deg bank turn causes a 1.1 to 1.2G acceleration which is enough to really feel the turn. A 60deg bank turn causes what most non-pilots and even MANY non-aerobatic pilots regard as an unpleasant G loading. It is actually only 2.0G. So you can see that to cut the Merlin out the change in force is equivalent to almost this (+1 G + 1G for a 60deg bank and only +1G (-) 0.9G to cut out.) Again to give some frame of reference, a large Roller Coaster is set up to give around 2G sustained force (momentary to about 5g but that is strictly momentary or everybody would be unconcious) and all those people "melting" and screaming are being subjected to the same as a 60deg bank turn or about the same degree
of force (but, of course in the opposite "direction") as is required to "cut" the Merlin.
Very hard to explain this to the coke swilling, all conqueuring, 9G monster, 300+ kill, 13 year old Doom Player set!!
From a flying
simulation point of view the overall effect is what we are looking for, particularly in "unusual" regimes of flight, which is not necessarily provided by the strict
figures. The Accusim Spit feels
right because it takes an "effort" to apply negative G until the engine cuts out....and the engine will otherwise behave properly. So the excessive effects of turbulence in sim and the fact that it is not "unpleasant" to reduce to 0.1G in sim are mitigated against and the overall effect is, in my opinion, about reasonable. We have the luxury of not having to chase Bf 109's
Of course normal flight figures MUST be adhered to rigidly as these are what the sim is (theoretically) designed for an these WILL give proper feel.
I have only ever once had a normally aspirated, standard carby engine "complain" about negative G (about -0.75) when we stayed there too long (my passenger panicked and grabbed my arm, making it hard to correct the situation!!). I have only ever maxed out at -3.0G in an outside loop and I can tell you, it is very unpleasant. I've never met a pilot (fighter pilots included) who liked neggies!! But give me +5.0G any day, +6.0G on Sundays and +6.5G on birthdays and Christmas..and I'd be happpy. As I am not a 5'5", no necked, chain smoking, high blood pressured, iron pumping, marvel (and I am told the best fighter pilots are
), I'll pass on anything over 7G. But I digress!
P.S.... Love that movie!! but I suspect the "roll" in BoB was done quite deliberately for the effect of the smoke....as a proper roll is a positive 1G manoeuvre and shouldn't ever cause cut-out when done properly...
