Alto Aviation’s new cabin management system (CMS) upgrades for the Gulfstream GIV and GV provide a simple means of replacing the original legacy Pacific Systems/Airshow cabin switches. The Alto switches are a direct replacement and are fit-compatible, which means that existing wood and furnishing are not compromised. Alto solutions include and fit "Micronet round, squared, raised-oval button, and the concave curved side ledge panels,” according to the company.
