3.3 Attitude Aligning / Keep Wings Level
If the “ALIGNING KEEP WINGS LEVEL” indication occurs during flight, the G3X Touch has detected
an invalid attitude solution and will not display any attitude information.
1. Use standby instruments to maintain 1
o
nose up pitch and wings level flight. The system will
display attitude when internal accuracy tolerances have been met.
2. Limit aircraft attitude to +10
o
bank, +5
o
pitch, 200 KTAS or less.
3. If attitude does not return, continue to use the standby flight instruments for aircraft attitude
control.
3.4 AHRS ALIGN
This annunciation indicates that the AHRS is beginning to fail and the internal sensors are trying to
realign themselves. The attitude presentation behind the annunciation is still valid but should be
crosschecked using the standby instruments.
