Alignment Invalidity
(Refer to Figure 3-17)
During alignment the “Align Hold” message replaces the attitude information
if the aircraft attitude is beyond straight and level flight for too long a period,
or if attitude is in a heightened dynamic state.
While the message is active and the ESI-2000 is configured for a
magnetometer as the heading reference, the heading readout is removed
and the heading tape is filled with a red X. Returning the aircraft to non-
dynamic straight and level flight will cause the “Aligning” message to
return.

NoTE
Release 1.2. The heading tape and readout is available
if the unit is configured to receive external digital heading
and heading data is valid.
