SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS & CNS AUDIO PANEL AVOIDANCE MANAGEMENT Flight Management Altitude Constraints The system can use altitude constraints associated with lateral waypoints to give guidance for vertical navigation. These altitudes are, depending on the specific instance, manually entered or retrieved from the published altitudes in the navigation database. The navigation database only contains altitudes for procedures that call for "Cross at" altitudes. If the procedure states "Expect to cross at," then the altitude is not in the database. In this case the altitude may be entered manually. Altitude Constraint Examples 5OOOFT Cross AT or ABOVE 5,000 ft Displayed Text Examples Light Blue Text with Pencil Icon 23OOFT Cross AT 2,300 ft White Text 3OOOFT Light Blue Text Cross AT or BELOW 3,000 ft White Text with Altitude Restriction Bars Figure 5-139 Active Flight Plan Screen - Waypoint Altitude Constraints White Text Altitude calculated by the system estimating the altitude of the aircraft as it passes over the navigation point, or altitude retrieved from the navigation database. The altitude is provided as a reference and is not designated to be used in determining vertical speed and deviation guidance. Light Blue Text Altitude is designated for use in giving vertical speed and deviation guidance. Altitude does not match the published altitude in navigation database or no published altitude exists. The pencil icon indicates manual designation or manual data entry. Light Blue Subdued Text The system cannot use this altitude in determining vertical speed and deviation guidance because of an invalid constraint condition. Table 5-8 Altitude Constraint Color Coding Altitudes associated with arrival and approach procedures are "auto-designated". This means the system automatically uses the altitudes loaded with the arrival or approach for giving vertical speed and deviation guidance. Note that these altitudes are displayed as blue text up to, but not including, the FAF. The FAF is always a "reference only" altitude and cannot be designated, unless the selected approach does not provide vertical guidance. In this case, the FAF altitude can be designated. Altitudes that have been designated for use in vertical guidance can be "un-designated". The altitude is now displayed only as a reference. It is not used to give vertical guidance. Other displayed altitudes may change due to re-calculations or be rendered invalid as a result of manually changing an altitude to a non-designated altitude.
