5 STB (Stabilization)
The STB button turns the pitch and roll stability ON and OFF. It is also
used with the STB adjust mode and to override forced standby.
NOTE: Some controllers annunciate OFF when stabilization is OFF.
6 TRB (Turbulence Detection)
TRB is a switch used to select the turbulence detection mode of
operation. The TRB mode can only be selected if the FUNCTION
switch is in the WX or RCT positions and the selected range is 50 miles
or less. The weather/turbulence mode is annunciated in the mode field
with the WX/T legend. Areas of at least moderate turbulence are shown
in soft white. The turbulence threshold is five meters per second.
