[ACE-OF-ACES]

My point about the indicated airspeed is that the game uses a standard calculation that the actual instruments of an aircraft may not show. Its been discussed on another forum that the indicated readings we see in game more closely correspond with EAS. That's a whole nother topic.

Basically the IAS in IL2 has no instument error, thus in IL2 IAS is equal to CAS

what i'm saying is that if the plane in the test reaches 320 in a zoom prior to climb, that may not equate to the same speed in game. It may be faster or slower than that number, who knows. The TAS of the P-47 at that height was 345mph (at 65") but there are no indicated records. You could probably see where the D-27 top speed is in relation to indicated speed, and its probably pretty close but i'm not sure i can duplicate this climb (with the Late model, maybe)

Roger without knowing the angle they settled at in the ZOOM you will be very hard pressed to recreate this real world test in IL2

As for the angle of climb, it doesn't need to specify, it explains they were pulled into a climb until 165ias was reached. 165 happens to be the speed at which the P-47 reaches its best angle of climb. So my guess, and logical assumption is that they climbed at the best angle of climb for the duration of the climb (Vx)

Actully it does need to be specified

If you were planing on trying to reproduce the test in IL2

In that it is most likly the angle was changing during the ZOOM

That is to say due to the extra 'e' due to the higher starting speed they could climb at a larger/steeper angle

That is to say they ZOOMED until the speed was reduced to the best climb speed

But during the ZOOM they were most likly climbing at a higher angle than the angle they would have at the best climb speed

Why?

Because they could!

Keep in mind the goal here was to see how a ZOOM climb improved the time to climb (TTC) number from a standard constant speed (best climb speed) climb

At least until the speed slowed down to the 'best climb speed' of the plane

At which point they carried on as if it was a normal constant speed (best climb speed) climb test.

In short

Once they used up all the extra 'e' they were force to climb at the best climb speed
