The changelog for 4.4 mentions:

Exposed Fuelflow -> N1 controller table in .air file allowing more control over the FF-N1 relationship.

Is there an air file in 4.4 where this section has been added? I did look at the 4.4 SDK and the various air files but didn't find anything.

Thanx in advance :)

Look for AIR_P3DV440_CORRECTED_N1_FROM_FF in the TurboPropSample.asm example.

Thanx for the quick reply Mike. I did find this section and converted the asm into an airfile, but I couldn't find this new table in the created air file.

Apparently I'm doing something wrong, so any further help would be great! :)

What were you using to locate the table? Perhaps it doesn't recognize a new table ID?

I right-clicked on the 4.4 SDK turboprop.asm and selected open with asm2air to generate the air file.

When you say you couldn't find the new table in the .air file, how exactly are you trying to "find" it?

Mike

I did a line by line comparison with other turboprop files and the only engine related differences I could find are that table 545 (fuel px) is now gone and 1532 (epr) has been added.

I have verified the new table does in fact compile into the .air file and loads properly.

Are you using the new asm2air.exe included in the v4.4 SDK?

I assume you are using some sort of binary editor or third party editor... I have no idea why you are seeing those changes.

Mike

Thanx for testing. I've downloaded the 4.4 SDK and was simply right-clicking on the asm file and it was definitely converted with the new 4.4 asm2air.exe.

I'll re-download and re-install the 4.4 SDK and try again….

When you converted the asm file you did still have table 545 and no new 1532 table?

edit: uninstalled the SDK, re-started the PC, downloaded and re-installed the SDK. Same problem :(

There is no 545 and there is a 1532 - this is consistent with the previous version's sample file.

checked, thanx :)

One thing to note is that the SDK installs under Program Files by default. Without Admin privileges, asm2air will fail if it attempts to output within Program Files. If you run from a command line you would see "ASM2AIR: Error!".

Make sure you are outputting to a location that does not require Admin privileges, and let us know if that solves your problem.

I have the SDK installed together with p3d, afsd etc. on a dedicated SSD.
The SDK has its own directory on this SSD and when using the command prompt I get this:

F:\p3d sdk\Simulation Objects\Flight Model>asm2air samples\turbopropsample.asm
Microsoft (R) AIR File Compiler Version 8.01
Copyright (C) Microsoft Corp 1981-2007. All rights reserved.

Assembling: samples\turbopropsample.asm

It does convert the asm into an airfile, but without the new table. That's really weird.

I have tested this by dragging the .asm file on top of the asm2air.exe file and the generated .air file has the new table added correctly.

I also tested via command line, still works as expected.

That's really frustrating. I've even tried with the user account settings set to minimum. No joy. Maybe I am blind. What's the number of the new table?
