ESI-2000
Pilot’s Guide3-14
Operating Instructions
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 ight for too long a period,
or if attitude is in a heightened dynamic state.
While the message is active and the ESI-2000 is congured
for a
magnetometer as the heading reference
, the heading readout is removed
and the heading tape is lled with a red X.
Returning the aircraft to non-
dynamic straight and level ight will cause the “Aligning” message to
return.
Figure 3-17: Align Hold
NOTE
Release 1.2. The heading tape and readout is available
if the unit is congured to receive external digital heading
and heading data is valid.
