The D M E tone is higher at 1350 Hz to help you tell them apart. If the VOR fails, the DME repeats about every 30 seconds. The DME ID is sent once for every three or four VOR IDs. If the VOR also has DME, each transmits its ID if it’s working but synchronized, so they don’t step on each other. −) is sent, which the G1000 cannot decode.If there is no tone, the station is unusable even if it seems to work. The letters “ID” appear between the standby and active frequencies. Push the NAV volume knob to disable the audio filter that normally suppresses the tone. (AIM 1-1-3.c) Sometimes a VOR plays the ID too fast or reception isn’t sufficient for the G1000 to decode, so you must identify the VOR by ear. It won’t be instantaneous, but if it works, there is no need to listen to the audio identification. Next, the G1000 automatic identifier attempts to read the station’s Morse code. First, tune the desired VOR just as you load communications frequencies. Like any VOR, the correct order of operation is essential. If GPS fails, the pilot is left with no chair to sit on if the GPS music stops.) G1000 VOR Navigation Unless you have and retain a VOR receiver in the panel already, this seems a false economy. (Taking advantage of WAAS as a sole-source system, some newer GPS navigators exclude VOR receivers. But, do you know how to use your G1000 for VOR navigation, especially if there’s no GPS position to drive the moving map and other sensors? Mountainous Area the MON can lead you to an ILS or VOR approach within 100 NM that doesn’t need GPS, ADF, or DME. Built on about 600 strategically located VORs, you are at 5000 feet MSL or higher outside the Western U.S. The MON is useful only to a pilot who is skilled in VOR navigation. The Minimum Operational Network is the VOR-based alternative means of navigation should GPS fail or become unavailable. The unit is WAAS-equipped if WAAS is checked.ĪIM 1-1-3.f reminds us that pilots flying GPS-or WAAS-equipped aircraft that also have VOR/ILS avionics should diligently maintain proficiency in VOR and ILS approaches in the event of a GPS outage. Unsure? Go to the AUX MFD page and press the SBAS button. If your G1000 is WAAScapable, it requires no other radio navigation equipment. If your G1000 lacks WAAS, then its use under IFR requires an alternate approved and operational means of navigating the proposed flight route, per AIM 1-1- 17.2.a.2. Yet too many pilots shortchange themselves if they neglect the machine’s considerable VOR resources. Pilots gravitate to its feature-rich GPS capabilities. Properly used, a G1000 can make you look mighty good trekking the skies under IFR. Garmin has sold over 16,000 Garmin G1000 units since its introduction in 2003.
