WARNING
It’s vital you refer to the pointer that corresponds to
the current aircraft Flaps configuration for an accurate
AOA indication. Failing to do so may result
in inadvertently entering into a dangerous
AOA condition.
AOA indicator on.
Top pointer indicates Flaps
UP AOA, Bottom pointer
indicates Flaps DOWN AOA
AOA indicator pointers fade
out when the aircraft is on
the ground and the wings
are not creating lift.
5.9 Angle of Attack (AOA)
The Evolution Angle of Attack provides the pilot a visual display of the AOA trend
and the trend towards stall simultaneously in both the Flaps UP and Flaps DOWN
configuration. The AOA indicator can be displayed on any of the Split Screen (2/3) and
Thumbnail (3/3) tiles. For details on the AOA features and general operation refer to the
MAX PFD Pilots guild.
When selected, “ANGLE OF ATTACK” appears momentarily in the upper left of the view.
After a few seconds, the phrase contracts to “AOA”.
The Aspen AOA indicator is comprised of a fixed colored tape with Blue, Green, Yellow
and Yellow - Black Cross Hatch bands. Two pointers point to the AOA colored tape
indicator. The top Flaps UP pointer and the bottom Flaps DOWN pointer. Due to the
difference in the Flaps DOWN or Flaps UP aircraft performance it is possible for the two
AOA pointers to simultaneously indicate two different AOA performance regions.
