TRUE/MAG WIND [2L]:
Current true wind direction and speed (in knots). Displayed in small font when the wind
value is computed by the FMS, in large font when the value is frozen. When the scratchpad is empty, and A/C is
outside the polar region (latitude between N73 and S60), pressing LSK 2L will toggle between the True and
Magnetic display options. TRUE/MAG toggling is disabled, the > is not displayed, and TRUE is displayed in the
title line when the A/C is in the polar region. When the scratchpad contains a valid wind entry, pressing LSK 2L
will enter the wind overriding the displayed wind, if the wind value is frozen. The wind is frozen at low speed and
under failure conditions (TAS or heading input failure). Wind entry is also allowed when TAS and heading are
valid in DME/DME and VOR/DME navigation modes. After a cold start on ground, the wind value is not
displayed (field blank).
TAS (2R):
True Air Speed (in knots).
HDG/DA (3L):
Aircraft heading and drift angle.
TK/GS [3R]:
Current aircraft track and ground speed (in knots). Entry allowed only when navigating in DR
mode, to aid the navigation solution.
MAGVAR (4L):
Magnetic variation at aircraft position.
TKE/XTK (4R):
Present track angle error (Left or Right) from course of active leg and present cross-track error
(Left or Right) in nautical miles from the active leg. When a ROCKWELL3 EFIS is configured, the XTK value
displayed will be either the crosstrack relative to the arc (when the arc is being flown) or to the active leg
otherwise. In the case of procedure turn and hover procedure, the XTK will be blanked when:
•
Active leg is a CF leg, and
•
XTK distance is greater than 0.2nm, and
•
Track angle error is greater than 20 degrees
The appropriate altitude value field is displayed at LSK 5L key in the order of priority:
ALT (CORR) (5L):
When a baro-corrected altitude is available. The baro-corrected altitude can be:
•
A baro-corrected altitude received from the ADC, or
•
A standard pressure altitude received from the ADC with a QNH baro-correction applied, or
•
A baro-inertial altitude received from the IRS with a QNH baro-correction applied.
ALT (STD) (5L):
When a standard pressure altitude is received from the ADC.
ALT (IRS) (5L):
When a baro-inertial altitude is received from the IRS.
ALT (GPS) (5L):
When a geometric altitude is received from the GPS.
In the case of a dual GPS configuration (e.g. civil & military), the GPS altitude is the one received from the
active selected sensor (either military or civil GPS).
ALT (INS) (5L):
When a hybrid inertial altitude is received from the EGI.
ALT (MAN) (5L):
When none of the altitude sources are available, manual entry is allowed. Displayed in
large font.
METRIC ALT [5R]:
FMS system altitude, displayed in meters. Displayed only if selected in the display
configuration.
