Considering Pan Am purchased 12 factory new -500 with the active ailerons (ACS) and digital AP and was the largest operator for a while, they outfitted the -500 with two INS and Omega (ONS) in the center pedestal (Canadian Marconi, CMA‑740 Omega/VLF) to constantly feed the INS to correct for drift. Any chance of considering implementing a ONS, like Black Square did with the Starship?
