MESSAGE TYPE/COLOR CONDITIONS
TIME ERROR AT WPTXX II/W While the aircraft is in lateral managed flight, the FMGC
predicts that it will miss a time constraint (Refer to
DSC-22_20-30-20-28-A TIME CONSTRAINT/RTA -
GENERAL).
TIME MARKER LIST FULL I/W The system already contains four time markers. (Only four are
allowed).
TIME TO EXIT II/A The aircraft must leave holding immediately to satisfy fuel
reserve requirements. (Extra fuel is zero).
TOO STEEP PATH AHEAD II/A This message is displayed in cruise, if the aircraft is within
150 nm of its destination or in descent or approach phase and
in NAV mode and the descent profile contains a segment that is
too steep.
TUNE BBB FFF.FF II/A The system cannot autotune the VOR for approach or position,
because of a manual VOR selection.
UNKNOWN PROGRAM PIN II/W The system is unable to initialize, due to an incompatible or
undefined aircraft pin program combination (A/C type, engine
type, VMO/MMO parity) in the FMGC software.
UPLINK INSERT IN PROG

II/W An uplink message is currently inserted in the FMGS.
USING COST
INDEX NNN
I/W The system contains a flight plan, and the flight crew tries to
enter a zero fuel weight or a gross weight into it before defining
a Cost Index (CI). The FMGC defaults to the cost index from the
last flight.
