Hi Nick,
I can confirm that you receive no signal for ACO VOR (on 114.40) at KCAK, but you receive a signal on KAKR. I have tested this with our dataset and also with the stock data from ASOBO/MS, and in both cases, the result is the same - no signal at KCAK. So, it appears to be a bug in the simulation. Please report this in the MSFS forum.
Your second report about the missing approaches for KCAK is not reproducible. I have all approaches available:
MSFS2024 1.6.34.0 - C172 with G1000 - AIRAC 2513 installed - stock scenery:
Do you have a 3rd party scenery installed? When yes, it could be incompatible with the current state of the sim. I would recommend trying these steps:
FAQ - MSFS2024 (SU3 and above) - airport, procedure, waypoint, 3rd party & flightplan import issues
The approaches are included in the data, but it looks like something “blocks/disables” it on your system.
Cheers,
Richard
