gyro in Hurri and spit

[Azdack]

During a turn flying an Hurri or a  Spit the gyro locks for several seconds before returning to operation to show the way heading again....A setting to do to avoid this ? Thanks

That’s how it was back then. Fly straight and level to sort the gyro out.

Yeah, they often didn't even uncage them until they'd taken off because of their sensitivity.

[Jaegermeister]

That's what the magnetic backup is for.

Sadly the brit p8 magnetic compass is VERY uncomfortable to read ingame. I use TrackIR and I have to twist my neck and zoom and it's really annoying. I flew once in a Tiger Moth in RL and of course it was much better with the old pair of MkI eyeballs.

The Mechanization in IL2GB is a bit of a mess. Firstly the the DG should not just freeze as it does as long as your manoeuvering is within the gimbal limits (Typically +-55 deg in roll and pitch). It should accurately display the DG heading.  If you exceed the gimbal limits the heading scale (IRL) would actually spin.  As soon as you roll out you should be able to cage the DG and set it to the correct heading. In addition in IL2GB the P8 compass scale always indicates correct heading. In reality the main needle should always point to Mag North. To determine heading the pilot would rotate the verge ring such that North was aligned with the needle... the heading was then read off at the top of the compass scale .... this was the Heading then set on the DG.

 

As I understand it in  IL2GB the idea of the frozen DG is to simulate the spinning that would occur after gimbal limits are exceeded. Then the couple of seconds before it magically synchs to the correct heading is to simulate the pilot going through the compass setting to DG process.

 

As to the AH, the Brits did not really like the idea of a cage function on the AH (Read "First light" for a discussion on this). So most RAF built AH's didn't even have a cage function. In fact many US lend lease aircraft delivered with cageable AH had the function disabled in RAF use. so when the AH gimbal limits were exceeded (Typically 110 deg in roll and +- 70 deg in pitch) it toppled then the only way to get it erect again was straight and level flight for an extended period ... daft but that was the case way back when. With a cageable AH you could cage it before manoeuvering then uncage/reset it once wings level.

No, the idea of the frozen gyro compass is that it's caged. Basically, if you start aerobatic manoeuvres your pilot will "auto-cage" the gyro for you. If you fly straight and level for some time (30s?), it automatically uncages it again.

It does; depending on the map, the difference can be rather noticeable

The P8 needle in IL2 GB provides a continuous heading reference when read off the scale. In IL2GB the scale is fixed with N to the top of the instrument. IRL the Needle only points to Mag North. To get heading you then need to rotate the scale so the N is lined up with the needle you then read the heading by reference to the scale indicated by a marker (missing on the IL2GB P8) at the instruments 12 O'clock position. (Its modeled correctly in COD and DCS)

 

 

Also it is my understanding that Magnetic variation is not modeled in IL2GB ?

After learning how to use this thing in CloD, I agree the IL2 seems wonky or different. Maybe it's automatic? It's really hard to see this thing behind the joystick as well. In VR it's a little easier, but blurrier.

I've asked about it internally to see if anything can be changed, thanks. ?

If the RAF P8 gets fixed then it would be nice to give the German Patin compass a tweak to replicate its flexibility. It correctly reads Heading against the scale however the pilot should also be able to rotate the verge ring and scale. So if you want to fly a specific heading say 240, you would rotate the scale till 240 was pointing at 12 O'clock on the instrument. You then "fly" the needle towards the set heading heading. In this way once you have the needle pointing vertically up you are on heading. A simple but very intuitive device ... copied postwar by the Russians and the Chinese.
