Manual Sequence
Req’d
Altitude invalid – leg will not auto
sequence
In basic E-M aircraft
where the IFD does not
have altitude input, this
message will appear when
the FMS active leg is a
HeadingAltitude leg. In
this case, the FMS flight
plan will need to be
manually sequenced to
the next leg. Failure to do
so will keep the FMS
flying the heading
indefinitely.
