Bank
Bank hold was engaged by opening the “Aileron gain” knob. Desired bank was set by turning the
“Aileron” knob. The selected bank angle could be read on top of the Sperry attitude indicator gauge.
If both Heading hold and Bank hold were active (both the “Rudder gain” and the “Aileron gain”
knobs were open), the aircraft would roll to the desired bank angle and turn until it fell within ±10°
of the selected heading, where after it would follow the selected heading.
If the autopilot was flying on a desired heading with heading hold active, this had to be deactivated
before being able to use bank hold.
Avionics, modern cockpit
Well ‘modern’ should be taken with a grain of salt because it remains a very basic cockpit. On the
modern version that we based on the equipment of several Catalinas that are still flying , the Sperry
autopilot was removed and replaced with a radio and navigation console. The radio room is now
converted into a passenger compartment on most airworthy Catalinas.

Transponder
The transponder is a radio
transmitter / receiver
operating on radar
frequencies. If it receives a
ground radar interrogation
signal, it will return a coded
response of pulses and ID
itself on the ground based
ATC radar screen. This will give
ATC information of ID, altitude and ground speed. To operate the transponder, there are a number
of knobs and buttons described below:
OFF Turns the transponder off
SBY Turns the transponder on, but doesn’t reply to interrogations
TST
ON Turns the transponder on and replies to interrogations in Mode A operation
ALT Turns the transponder on and replies to interrogation in Mode C operation (Gives altitude
reporting) An “Alt” announcement is displayed
