Controls and Displays
FMS.30.128
CHECK/CONFIRM VSPDS - Appears for any of the following:
A pilot entered or pilot confirmed value of V1, V2 or VR is manually cleared.
• ALT T/O is selected as the thrust limit and V1, V2 or VR have been pilot
confirmed.
• Calculated values for V1, V2 or VR change from invalid to valid.
• Values for V1, V2, and VR can no longer be calculated because input
necessary for calculation has become invalid.
• A new runway is entered into the active primary flight plan and V1, V2 or
VR are pilot confirmed or pilot entered.
• Calculated value for V1, V2 or VR is found to be more than 2 knots
different than the pilot confirmed value for V1, V2, or VR.
• FMS transitions into the LAT ONLY state and V1, V2 or VR is not pilot
entered.
CHECK DATA BASE CYCLE - Appears if the following conditions are met:
• A new ORIG/DEST pair or CO RTE is entered in the active or secondary
flight plan.
• The date displayed on the DOC DATA page is valid and does not fall
within the nav database cycle dates.
• The cockpit chrono is valid and does not fall within the nav database
cycle dates.
CHECK WEIGHTS - Appears at engine start when:
• Pilot entered TOCG differs more than 2 percent from WBS TOCG or,
• Pilot entered TOGW differs more than 2 percent from WBS TOGW.
CHECK ZFW - At engine start, if BLOCK and UFOB differ by more than 500
kgs. After engine start, if BALLAST is entered or edited.
CLB ALT CSTRS DELETED - Descent is entered before all of the climb altitude
constraints have been sequenced. All altitude constraints are associated with a
lateral leg and are sequenced when that leg is sequenced.
CRZ ALT CSTRS DELETED - Descent is entered before all of the cruise altitude
constraints have been sequenced. All altitude constraints are associated with a
lateral leg and are sequenced when that leg is sequenced.
CRZ FL ABOVE MAX FL - The cruise flight level for the active primary flight
plan has changed and is above the computed maximum flight level.
CRZ FL(S) REMOVED - Appears if one of the following conditions is met:
• A new cruise altitude is entered above a step altitude causing the step to
the lower altitude to be removed.
• A transition to descent or approach occurs, with multiple Cruise flight
Levels entered for the active primary flight plan.
