P-47's AI unable to reach cruising speed

[greybeard_52]

Hi,

I would like to enjoy a career with P-47 but its AI looks very handicapped starting with the real cruising speed that it can reach. Planned one is 400 km/h (as I can read on the map), but actually the AI flight leader reaches only 210 mph (337 km/h), forcing the whole flight to compromise its stability and controllability cause the pitched attitude, also due to heavy bomb load. I tried also with PWCG, but there it is even worse, since P-47's AI trudges at 150 mph (241 km/h), in a strongly nosed attitude, notwithstanding the planned cruising speed was 380 km/h.

Yeah, I agree.  I think there's some confusion in the modeling.  In (null)/luascripts/worldobjects/planes/p27d22 at the bottom of the p47d22.txt it shows ClimbV = 160.0.  I think that's in mph which would be per handbook (and is way too slow and will cause engine overheating in the sim), and because kph would be 100 mph and it would fall out of the sky.  However, MaxFlapV = 315 which can't be mph and has to be kph.  315 kph translates to 195 mph which is per the handbook.  So, I'm wondering which system does the model use, Metric or English.  The numbers in this file seems to indicate a discrepancy.  Is it using both?

 

I prevously commented on the CriticalAoA of most of the Fw's all being less that of the Fw-190A3.  Someone responded that the Russian translation of the line desription says that info is for technochat and not modeling, but I don't buy that as I've never seem CriticalAoA appear in technochat.

I tried a few different planes in career mode and found that the AI is pretty bad at formation flying.  Sure, they hold position but, they also speed up and slow down suddenly and sometimes change course drastically without warning.  If you don't start the career as always the flight leader, then watch out!  If your position is in the middle of the pack, the planes ahead of you and behind you fly with enough space for you to fit in but, don't care at all if you fall out a little bit. They will hold course and crash right into you as if they can't "see" you at all.

It wouldn't be first time that a confusion is made between systems of measurements. Did you try to put just metric historical values?

I tried to restore the historical metric value of the P-47D-22's speed of climb, but the program refuses to start the mission, returning an error message.
I verified that the P-38's AI is also not capable of reaching the planned cruising speed: 320 instead of 360 km/h. I think the defect concerns more than one airplane, I hadn't noticed it before because the differences were relatively modest, up to the case of the P-47, particularly serious, to the point of compromising its playability.

If it’s a bug make a bug report with video or screenshots of the problem. This topic sitting in complaints is not going to do much. And mobile is right. Unless you are flight lead you’ll be handicapped by this problem.

Ok Mr. forum warrior.   My point was that it's not just the P-47 that has problems with keep a good cruising speed in career mode.  It's not a P-47 problem, it's an AI problem for pretty much any of the planes.

Yes, I ran my own tests last night and confirmed as well it's an AI issue, as the P-47 can reach 400 km/h with even the heaviest external loads on max continuous power. I've let the developers know about the problem.

I think you're right, but I haven't done extensive testing on this to be able to tell.

Thanks for collaboration.

I can confirm that in all the planes I've tested so far the AI does not reach the cruising speed foreseen in the flight plan, except by accident. It seems to me that the game engine follows its own logic in this regard, regulating the cruising speed of the AI always lower than expected and even variable along the route.
