1.5VERTICAL NAVIGATION

OneoftwoaltitudesourcesisusedbytheG1000when giving vertical navigation guidance. WAAS GPS altitude is used when giving guidance for a WAAS approach after the Final Approach Fix. Baro corrected altitude is used when vertical guidance is given in all other situations and in non-WAAS systems.

The G1000 system can use altitude constraints associated with lateral waypoints to give guidance for vertical navigation. These altitudes are, depending on the specificinstance,enteredbythepilotorretrievedfromthe 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.

NOTE: All arrival procedure altitudes contained in thenavigationdatabaseareforturbojetaircraftonly. Alterorenteraltitudesasdesiredtocomplywiththe ATC clearance.

When activating or loading an arrival or approach procedure into an active flight plan, the VNV ‘ALT’ fields are populated with any altitudes that can be retrieved from the navigation database.

Since altitudes loaded with an arrival procedure are published only for turbojet aircraft, the altitudes are displayed as white text indicating that the altitudes are displayed for reference only. An arrival waypoint altitude may be used (or “designated”) as is, or changed to a different altitude. An altitude is designated by pressing the FMS Knob and turning the large FMS Knob to place the cursor on the desired altitude and pressing the ENTKey or entering a different value and pressing the ENT Key. The altitude is now displayed as light blue text, indicating that

the altitude is now designated to give vertical speed and deviation guidance.

Approachwaypointaltitudeconstraintsareautomatically designated when the approach is loaded. These altitudes are also displayed as light blue text. Waypoint altitude constraints designated 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 manually.

Altitudes that have been designated for use in vertical guidancemayalsobemade“non-designated”byplacingthe cursor over the desired altitude and pressing the CLR Key. Otherdisplayedaltitudesmaychangeduetore-calculations or rendered invalid as a result of manually changing an altitude to a non-designated altitude.

To help interpret the meanings of how the altitudes are presented, keep the following points in mind:

•When the altitude is displayed in light blue, the system is using that altitude (designated) to determine vertical speed and deviation guidance.

•Whenthealtitudeisdisplayedinwhite,itisnotbeing used by the system (non-designated) to determine the vertical speed and deviation guidance.

•Altitudes displayed as a light blue subdued text cannot be used in the current vertical navigation calculations.

Refer to Figure 1-8 and Table 1-1 for more detail regarding the significance of text size and color.

Some altitudes retrieved from the database have associated restrictions indicating to stay ‘At’, ‘At or Above’, or ‘At or Below’ a specific altitude. These restrictions are indicated using a ‘bar’ above and/or below the appropriate altitude as shown in Figure 1-9.
