Operating the E135 with AHRS AH-900, I found system limitations,
concerning LATITUDE and LONGITUDE restrictions in AFM section 2-24 and AOM 1-01-56.
The E145 has a different (older) AHRS AH-800 installed for which I could not find the same restrictions in AFM and AOM.
Question Embraer on the issue, they responded that the AHRS AH-800 uses flux valves (which is true) but I think they ignore the fact that the AHU is working with gyros (wich are slaved to the flux valve).
It may be that the limitation was omitted in the Primus 1000 guide, and therefor in the Embraer AFM and AOM.
I tried to get more info in the Honeywell Primus 1000 pliot guide, but this one does not present a limitation for the AHRS AH-800 either (it does for the AH-900). It contains a reference to a dedicated AHRS pilot guide, Honeywell publication number M28-3335-001. I phoned Honeywell to obtain this guide, but this seems to be difficult.
Could someone confirm me with certitude that there is indeed no limitation for the AHRS AH-800, or provide me with an (electronic) copy of the related guide or the limitation section of it?
Thank you all and best regards.
