Ok, maybe you are not going to like this but I am trying to understand and I am not arriving to proceed properly. Following your last post, I thought that 0B54 was 32 unsigned but float. So, I first tried with FLT, the result stay at 0 even when in the PMDG 777, the APU Rpm are at 100 %. So, I guess that maybe this PMDG Addon does not use the P3D Apu but an inbuilt solution. Will investigate further to find a solution By the way It would be so much easyer (at least for me) if instead of size column, there would be a nType column in the offset document maybe.

I did try to understand before coming here to ask for help. I also hoped that coming here could help me to improve and be more autonomus in the future. Your answer are helping me in that way, thank you for them. In fact, I did not match the size with the 8-16-32-bit and that is the main reason I was finding it so hard to understand. My native language is French, I try to do my best in English and that maybe does not help. Anyway, Thanks for your help and hope I will manage alone for my next steps Regards Nicholas

Thank you very much for your help. I must admit that I do not really understand the offset list in regard of types of offsets even if I tried to via reading the Lua Library guide and the FAQ explaining it. Anyway, I now have the value I wanted, I'm happy. I will now work on the engine starter switch 0892 ipc.readUB (my guess) and APU 0B54 ipc.readSD (again my guess)

Hello, I've spent my afternoon trying to find out how to convert the pressure altitude offset into the same unit result than the altitude (0x0570) Im my .lua file, I have this : lat, lon, alt, pitch, bank, hdgT = ipc.readStruct(0x0560,"3DD", "2SD", "1UD") palt = ipc.readStruct(0x34B0, "2SD") alt = alt * 3.28084 / (65536 * 65536) palt = palt * 3.28084 / (65536 * 65536) but the result does not match. Also, I would like to know what offset to take and how to check when : Engine 1 is "stabilized". I tried with offset 0894 but it seems that the result varies depending on the throttle. I was more looking for a kind of result indicating engine stabilized so I can start engine 2. APU is available (at 100%) No tried yet, I ask before I spend another day to find a maybe easy answer to find here. Thanks in advance for the help Nicholas
