We later told a Check Pilot about it he maintained that the PF was to manipulate Cyclic, Pedals and Collective at all times and he would fail the rides of any crew who did that.
I guess he thought the PNF’s function was to be an interested spectator and contribute nothing more to events than fervent prayer and childish screams
Those in power can have some odd ideas, was riding shotgun while a lad was gaining the requisite ICUS time to progress to a command in a two crew operation, a problem developed and in good CRM manner the issue was discussed and an option decided, chief pilot wouldn't let the lad log ICUS as he didn't make all the decisions ie we were not to discuss our options.
