predattak,
Spaz’s information is all that is likely to be available in finding the AOA in degrees since “The cam-operated switches in the angle-of-attack indicator also control the approach indexer.” Thus the optimum approach AOA in degrees is passed internally and not available.
I had this road block to be able to use vLSO with my T-28C which does not even have an AOA indicator or an Approach indexer. Likely others will have the problem as more aircraft are wanting to become supported in vLSO.
While there may well be other ways to get the AOA degrees for the 4.12 deg. and the 3.5 deg. glide slope, here are some suggestion:
1. Contact the Dev or the person who did the FDE for the sim model and ask if they will provide the AOA needed in degrees. It worked for me;
2. Look at the supported planes in present vLSO and see if there are any close to your airframe design since AOA is in part airframe specific(i.e.,S-3B Viking) . If so, load the AOA values data into vLSO and test fly using the onboard AOA indexer and the vLSO approach data record to fine tune the optimum approach AOA in degrees. The abeam variables should be available in the
