OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
V/B V/S [4R]:
OR
DIST TO ALT [4R]:
This field can display one of the following options based on the selection that was made at [3R]:
• Vertical situation awareness to be maintained relative to the waypoint and altitude displayed at [3R]:
• The “V/B” field displays the current ground-referenced vertical bearing from the aircraft present position
to the waypoint/altitude displayed at [3R], in degrees.
• The “V/S” field displays the vertical speed in ft/min required to achieve a vertical path angle equal to the
vertical bearing at current ground speed.
• When [3R] and [1R] are identical, the data field is only displayed when descent mode is active. When
[3R] is a manual entry, the data field is displayed at all time. The data is displayed in small white font.
The "V/B" and "V/S" data field are blank when vertical guidance is not available.
OR
• Predicted ground distance to the altitude displayed at [3R] based on the current aircraft altitude, ground
speed and vertical speed:
• this distance is only displayed when:
• The aircraft is airborne; AND
• The active VNAV mode is Climb or Descent/Approach (nothing is displayed in this field when in
Cruise) AND
• no altitude conflict exists between the current aircraft altitude and the altitude displayed at [3R];
AND
• Baro-corrected altitude data is available when the altitude displayed at [3R] is:
• Below the transition level during Descent; OR
• Below the transition altitude during Climb.
Toggling between both options occurs when [3R] is pressed and nothing is displayed in the scratchpad.
FPA VDEV [5R]:
Displays the vertical deviation relative to the FMS computed descent path with a resolution of 10 feet and a
range of 0 to 9990 preceded by the current aircraft Flight Path Angle.
Positive values indicate that the aircraft is above the pre-computed descent path. Negative values indicate that
the aircraft is below the pre-computed descent path.
The title and data field are displayed when the aircraft has passed the T/D anticipation point or the descent
mode is active. The FMS will blank the title and data field when vertical guidance is not available (if configured
for Path descent). When present, the values are displayed in small white font.
The "FPA" field displays the currently flown aircraft descent angle, which can be expressed as the aircraft pitch
attitude minus the angle of attack. The value, in degrees, is relative to the air mass without a +/- sign.
PROFILE [6R]: When "PROFILE" is present, enables direct access to VNAV PROFILE 1/X page.
DES NOW [6R]: "DES NOW" prompt is displayed when the cruise mode is active and the aircraft is within 50
nautical miles from the top-of-descent. Pressing the LSK while "DES NOW" prompt is present sets the FMS in
"MOD" state and the EXEC key to lit. Upon pressing the EXEC key, the descent mode becomes active.
NO PROFILE [6R]: Indicates that no vertical profile is computed during FMS engine-out climb mode and
consequently, access to the PROFILE page is forbidden.
