737 FMC
U10.6 Changes
Mark Peterson
Avionics-FMC
Boeing Commercial Airplanes
May 2004
The Boeing Company 737.2
737 FMC
• Remaining automatic switches to speed descent
mode are removed. Selecting the SPEED prompt is
the only way to get into the SPEED descent mode
• “Geometric” Path descent is now basic, not optional
• Switch to path on “point to point” legs
• Nuisance VNAV DISCONNECT message during
flare and landing is eliminated
U1100..66 VNAV Baassiicc Chhaannggeess
The Boeing Company 737.3
737 FMC
• Descent path now extends beyond lateral
discontinuities
• Approach waypoint altitude constraints cannot be
deleted with altitude intervention
• Allow crew modification of runway angle (for VFR
approaches). Added a field for angle entry to ARR
page, under RW EXT field
U1100..66 VNAV Baassiicc Chhaannggeess
The Boeing Company 737.4
Geometric Path Descent (Basic)
Late Descent or Speed Intervention
VNAV switches from VNAV SPD to
VNAV PTH on “point to point” leg
“Non-geometric” option no
longer available
The Boeing Company 737.5
Descent Path After Discontinuities
Speed/altitude
predictions.
The Boeing Company 737.6
Altitude Intervention Cannot Delete
Approach Waypoint Constraints
Base approach altitude constraints can be deleted
only via the CDU (to prevent inadvertent deletion)
Cannot be deleted with Altitude Intervention
The Boeing Company 737.7
Crew Defined Runway Angle
New
field
The Boeing Company 737.8
10.6 Optional VNAV Changes
Added as part of Common VNAV option:
• Use VNAV SPD instead of overspeed disconnect for
unforecast tailwinds or late descent (Common with
other Boeing FMCs)
• Remove SPEED DES prompt from DES page
• PATH or SPEED removed from DES page title, since
it is now always path, e.g., ACT ECON DES
• Common VNAV will provide increased commonality
with other Boeing FMCs and reduce training
The Boeing Company 737.9
Common VNAV
VNAV SPD used for late descent and reversions
Page title changed
SPEED
prompt
removed
The Boeing Company 737.10
Common VNAV
Descent path recaptured when
airplane satisfies capture criteria
The Boeing Company 737.11
Other U10.6 Features
• Improve SEL DES WPT page:
– Add capability to display names of airports,
navaids, and non-directional beacons
– Added NDB frequencies
– New page format can be used with or without
extra data in navigation data base
The Boeing Company 737.12
SELECT DESIRED WAYPOINT
Name added in header, and frequencies displayed, matches charts
Old page.
The Boeing Company 737.13
SELECT DESIRED WAYPOINT
Names in the navigation data base may be omitted to keep data base
size smaller for mixed fleet use with older FMCs such as U5. The page
display is the same, minus the names.
Old page
The Boeing Company 737.14
Other U10.6 Features
• Speed Propagation (Option)- When a manual speed is
entered on CRZ page, it propagates to the rest of the
vertical pages (like MD80/90)
• Four additional FIX pages for a total of six (Option)
• Quiet Climb modified to keep CUTBACK enabled during
reentry of Vspeeds (Improvement to QCS Option)
• LNAV Change to reduce bank angle at high altitudes
(Basic)
• Takeoff Speed Order Checking (V1<Vr<V2) (Basic)
The Boeing Company 737.15
Speed Propagation
300 entered on CRZ, propagates to DES
The Boeing Company 737.16
