Slip/Skid Indicator
(single engine)
During one--engine
inoperative conditions,
the slip/skid indicator
is repeated below the

When the airplane is in the take--off

middle (drawn solid) to be used as
a pitch reference during take--off or

Markings indicate bank angle (degrees of roll).
tick marks are
only displayed

Unusual attitudes / Unusual AOAs
An unusual attitude or unusual AOA would result in
either the horizon line or the flight path symbol
exceeding the limits of their display areas. The affected
symbol will then be ghosted (displayed in dashed lines).
In this event, the vertical components of the attitude
display will be compressed to provide a consistent
display which is relatively correct to each other,
although no longer conformal to the outside scene.

Attitude Failure Flags
ROL and/or PIT and/or
An IRS failure is indicated by the above
failure flags and the affected attitude data is
removed from the display.
A miscompare is indicated by the same
failure flags but affected attitude data is
retained. The flags flash for 5 seconds
when the miscompare is first detected and
thereafter remain displayed until the
condition is corrected.

Attitude Source
Default source is ATT 1 and is
