Me 262A-1 manual

Section 2 - page 7.
Airspeed Limitations:
Max allowable airspeed (IAS) is 950 km/hr or 590 mph

FM Guru's riddle me this, if a US test pilot (someone that will not really push a captured German aircraft to it's limits) advises a pilot should never exceed 950 km/hr, does this not mean that 950 km/hr is the max safe speed of this aircraft? If the answer is yes, this must mean that the current FM of the Me 262A-1 is incorrect since you loose all control surface response at something like 740 - 750 km/hr?

At AAA we do not mod the FM's of stock aircraft.

test pilots get paid to take an airplane to its' extreme limits, hence the name test pilot. it may be far more involved now with modern planes but eventually someone needs to go out wring the sh*t out of it to see what it can really do.

in Me-262 the Airspeedindicator indicates TAS and I have gone way beyond 750 with keeping control, actually i scrathed the 1000 in a safed dive.
I do not experience the limitation you point.

- F22-Raptor-2006 - 16.08.2009

it's game limitation making u blow up hitting sound barrier basically..

- Guest - 16.08.2009

Real 262 could go supersonic in a dive...problem is that when you get close to speed of sound you loose control effectivnes and nose pitches down...this was proven a few years ago in a wind tunnel testing in Germany....interesting thing is that once you are supersonic you regain control of the plane..

Well you did on the Hawk 75

Hard landings and high-G manovers will warp a metel airframe severely thus reducing performance capibilities. Remember that the all-metal construction of these birds was fairly new and not well understood at the time.

High G manuvers do not warp airframes and both monocoque and semi-monocoque construction was well understood at the time. Surpassing the ultimate load factor can indeed inflict damage to the airframe but just stating that high g maneuvers will accomplish this is wrong.

No, we did not. The Hawk-75 remains the same as it was. Karaya was the one who created a *new slot* Hawk-75.

- P/O W. 'Moggy' Cattermole - 16.08.2009

To clarify: AAA does NOT ever alter an FMs, DMs, WMs etc of any stock aircraft ever, to ensure online compatibility. Karaya's own Hawk75 is going to be in a new slot. It'll be a brand new aircraft modded in, like the Me410.

- JG7_X_Man - 16.08.2009

OK - Let's stay focused: Does this not read 751 Km/hr?

This is the speed at which I loose control serface response.

- Guest - 16.08.2009

You've got to remember Indicated airspeed is exactly that, Indicated. Your true airspeed is much faster.

- JG7_X_Man - 16.08.2009

Thanks Anto! But I was not able to do this.

Can someone please post a screen shot of the Me 262 A-1
1. Crusing at 850 km/hr (IAS)
2. Diving at 950 km/hr (IAS)

Thanks

You are talking about the problem with transonic speeds.

- Sancho - 16.08.2009

The slipball in the screenshot you posted is pegged left. Either your leaning on the rudder, have trimmed the aircraft out of co-ordinated flight or your only giving power to the left engine.

The 262 modeling in game easily maintains 850kph true between 2km and 9km and doesnt start losing pieces untill well over 1000 kph.

Just remember the IL2 game engine wasnt intended to extend to high altitude and highspeed so it doesnt easily lend itself to the 262 flight envelope.

The 262 being capable of supersonic flight is generaly regarded as a myth based on ancedotal evidence from a single pilot. Post war engineering analysis ( including testing by Willy Messerschmitt ) concluded the airframe wasnt strong enough to withstand the transonic buffeting not to mention the engine inlet design wasnt capable of feeding the engines at transonic/supersonic speed limiting the speed of the design to about mach .85.
