If the system is installed and maintained properly it works as advertised. There were a number of issues in the initial installs but these have since been corrected. Normally 3 fingers are enough to pull the lever with the hand still on the cyclic grip. Every 3 years an actual inflation is required with bottles, bottle cables, and floats replaced.

With no cushions on the PIC seat and plastic on SIC seat, my guess they are installing/replacing the float bottle cables. Installing the shear pin ( "A" rivet) is one of the last things to do.
