Me-262 gyrocompass

Also, the flaps actuators on the cockpit do not seem to be functional (iPhone 15 Pro).

Has anyone else noticed this?

It works on my iPad 9 when I press the buttons.

Oh, okay. I just realized that you have to hold down the buttons for them to work. Thank you!

Can anyone help me figure out how this device works? When turned on, it always points east and won't do anything else.

You turn the centre knob to align the magnetic compass heading with the nose of the aircraft symbol thing. Where is the magnetic compass? There must be some way to get 360/0 degrees pointing straight up on the aircraft symbol thing? Perhaps it was intended for a remote sensing compass like in the P-38? In real life a lot of design features got left off production machines.
The comprehensive Aerofly guide is bound to explain everything.

In the meantime align it on the ground against the runway numbers or turn on the top of the screen information. Good Luck! I find the 262 less than pleasant at this time.

(You are not missing setting the trim in the P.C. FS4 version, dead slow (using joystick or keyboard presses), takes for ages to have any effect. The orange knob slides forward and back, the trim gauge is just outboard).

It is a ‘Fl 23334 leader’s daughter gyro compass’ which is supposed to be slaved to a remote electronic compass and flux gate. Periodic manual adjustment was guided by an external ‘astrocompass’ which had an inclined sundial-like sun azimuth angle scale which presumably rotated as the plane turned. It was to provide a compass and presumably latitude corrected inclined sun angle additional bearing guidance to supposedly better cope with aircraft heading alignment and calibration difficulties from high speed flight.

Most movement should be of the aircraft symbol via the slaving to the remote compass (which the sim apparently does not/can not do) and lacking modern automatic updating the gradual errors could be manually adjusted on/against the background compass card (which is sort of available in the sim but rotating fully to provide all of the direction information).
The gauge operation in the sim is probably fundamentally incorrect IF, IF I have got this correct.

The P-38 and Corsair had/have similar compass and directional gyro problems with authentic implementation in Aerofly.

Nice but.

No, I'm not into premium

Have you ever seen this short video of a cockpit tour?

Maybe the sim's trim forces are not that bad.

(What do you think of the power? at 375 mph is that about four thousand horsepower at about the same weight as a Grumman Hellcat or are those the modern General Electric engine numbers? It seems a bit lively)

No the maths makes thrust equal to horsepower at 375 mph.
With a jet the power generated increases as it goes faster. At take off from a stop the ‘power’ output is zero at the instant before the plane moves, no matter how much thrust is being applied. Force multiplied by zero speed divided by time gives zero horsepower. There is no ‘power’ but there is acceleration.

No Hellcat ever flew with a Me 262, the sums’ numbers match well though.

The 262 at 375 mph had about the same mass but about twice the power.

The 4,000 lbs thrust Me 262 and the 2,000 horsepower Grumman Hellcat at 375/2 or 188 mph had about the same horsepower.

At 375*4/10 or 150 mph the Me 262 had only 80% of the Hellcat’s power.

At a near stall 375/3 or 125 mph the Me 262 had only 67% of the Hellcat’s power.

That is why the jets were ultra vulnerable at landing speed, the propeller plane had all the advantage. Unlike the sim’s 262 the original engines lacked automatic engine control and had to be gently coached into increasing their revs and power output. The early engines also lacked rapid thrust increasing features such as switchable compressor bleeds on the landing approach and variable pitch compressor stator vanes.

Re Other.

You ever see the Lakes Buccaneer amphibious single? Its engine is on a high pylon between the wings keeping the propeller and cooling air intake and shock cooling vulnerable air cooled engine cylinders well clear of the water spray. They would dip the nose with power application.

Thank you for this very interesting technical analysis.

Another question: The maximum speed was around Mach 0.71, and the aircraft became uncontrollable due to violent vibrations in a nosedive at Mach 0.86.

However, did Hans Guido Mutke really manage to reach Mach 1 without breaking up, because if this is officially the case, the Me262 would be the first jet plane in the world to have reached the sound barrier and not the Bell X-1, or are there still doubts on this subject?

What is your opinion?

It must be true, I saw it on a YouTube comment.

hey guys can anyone give me a tutorial on how to start the 262 from cold and dark?
