Our automated rapid deployment airstairs are self-contained assemblies that are built to withstand normal day-to-day use in most environments. The airstairs mount directly to the cabin floor of your Boeing 747-200 aircraft and can easily be stowed away in a non-obstructive compartment when not in use.
