The obstacle clearance, within the limits of the airway, is typically 1,000' in non-mountainous areas and 2,000' in designated mountainous areas.Communication is not necessarily guaranteed with MEA compliance.The minimum en route altitude (MEA) ensures a navigation signal strong enough for adequate reception by the aircraft navigation (NAV) receiver and obstacle clearance along the airway.When the AeroNav Products en route chart is unfolded, the legend is displayed and provides information concerning airports, NAVAIDs, communications, air traffic services, and airspace.The en route charts are revised every 56 days.Information concerning MTRs is also included on the chart cover.The effective date of the chart is printed on the other side of the folded chart.Also noted is an explanation of the off-route obstruction clearance altitude (OROCA).Cities near congested airspace are shown in black type and their associated area chart is listed in the box in the lower left-hand corner of the map coverage box.When folded, the cover of the AeroNav Products en route chart displays an index map of the United States showing the coverage areas.The IFR low altitude en route chart is the instrument equivalent of the sectional chart.To effectively depart from one airport and navigate en route under instrument conditions, a pilot needs the appropriate IFR en route low-altitude chart(s).Established jet routes from 18,000' MSL to FL 450 use NAVAIDs not more than 260 NM apart.Information includes the portrayal of Jet and RNAV routes, identification and frequencies of radio aids, selected airports, distances, time zones, special use airspace, and related information.En route high-altitude charts provide aeronautical information for en route instrument navigation at or above 18,000' MSL.AeroNav Products maintains and produces the charts for the U.S.Your ability to fly instruments safely and competently in the system is greatly enhanced by understanding the vast array of data available to the pilot on instrument charts.The objective of IFR en route flight is to navigate within the lateral limits of a designated airway at an altitude consistent with the ATC clearance.If your external GPS/NAV device is configured with this behavior enabled, one important detail is that such devices ALWAYS control whether its GPS or NAV radio is providing guidance. (2) Some devices, such as the Garmin 430, 430W and GTN series, can automatically change from the GPS to the localizer and send asignal to the SkyView to automatically change the HSI source at the appropriate time. (1) If the GPS does not support auto - switching from GPS to NAV, you must manually perform this action by using AUTOPILOT > HSI SRC. "Note: If an ILS approach is being flown with another navigation source being used in the transition, for example an approach approved GPS navigator, upon being cleared forand activating the approach the SkyView HDX’s HSI source must be switched from GPS to NAV. Maybe we can see this in a future update, as I think the ILS approach with Skyview selected as HSI source would not really work as it does atm. This behavior is also available in the actual Skyview: Just now noticed that it automatically switches to NAV mode once established. Stupid me thought this would work as the needle moves in the standard cessna as soon as the localizer has been found. You're 100% correct.Īso found this in the meantime within the "real-world" Skyview manual: NAV radios tuned to a LOC/ILS frequency do not provide bearing information due to the natureof the localizer radio signal. Switch to LOC1^ -> correct indication of active path but BRG1 still horizontal: Of course the ILS works just fine if I stay in Skyview, but imho this would not be correct?Įstablished in Skyview (GPS) Mode -> BRG1 pointer still horizontal: I can see that the localizer has been found as I see the glidepath indicator even in Skyview mode. Once I change source from Skyview to LOC1^ it behaves correctly. But the BRG1 pointer will always stay in the horizontal position as long as I don't change modes. I would expect that the BRG1 pointer would move once the localizer has been found (at this point I would usually change modes and activate approach). Also I set BRG1 to to LOC1^ so that the yellow bearing pointer appears. I'm flying in Skyview mode (GPS) to the entry point of my glidescope. This is especially valid for ILS approaches:įor an ILS approach I set frequency and bearing to the correct values. It seems like the secondary BRG1 and BRG2 pinters are not working if a localizer frequency has been set (works fine with VOR frequencies). I'm not sure if this is an issue or if I'm doing something wrong.
