Pilot Input / Output Port
The Pilot input/output port is a part of the AIS Class A stations. If the installation of
the AIS equipment is such that a pilot cannot connect his Personal Pilot Unit (PPU)
with a reasonable length of cable, an extension cable must be installed with a con-
nector located on the bridge such that the PPU can be connected on the normal
working position of the port.
