User manual GARMIN APOLLO 604

[. . . ] Your new NMC and peripheral sensors should be installed only by an FAA certified facility. Each installation is unique, and there are several variables and cautions that an installer must deal with for you to get the maximum benefit from your Apollo NMS. Important Notice The Global Positioning System (GPS) is operated by the United States Department of Defense which is solely responsible for the accuracy, daily operation, and maintenance of the satellite constellation. System accuracy is affected by the Department of Defense's Selective Availability (SA) and the Dilution of Precision (DOP) attributed to poor satellite geometry. Due to implementation of Selective Availability by the United States Department of Defense (DoD), all GPS receivers may suffer degradation of position accuracy. [. . . ] Flight Trigger choices are: OFF, At Power On, and selectable for speeds from 10 to 500 knots. In this example, the Flight Timer is activated when the ground speed exceeds 30 knots. FLIGHT TIMER TRIGGER AT 30 KTS SYS 166 Operations SYS Mode Displays Direct-To Entry The display below is used to choose the Direct-To Entry Option, which affects how entering a Direct-To waypoint is handled by the Active flight plan. DIRECT-TO ENTRY NEVER CLEARS ACTIVE PLAN SYS System Info Sub-State Displays The system information Sub-State displays show information and settings pertaining to the NMS (Navigation Management System). Date/Time (UTC) The screen below is used to display and edit the current time/date. The NMC uses a 24 hour real-time clock to calculate ETA (Estimated Time of Arrival). Also, GPS sensors require the current UTC (Universal Coordinated Time--formally called Greenwich Mean Time) to locate satellites and determine position. In this example the current UTC is 15:14, and the date is February 11, 1999. DATE: 11 FEB 99 TIME: 15:14 UTC SEL TO RESET SYS Fuel Measure Units The screen below is used to choose the measurement units used in fuel data displays. The system must be interfaced with a F/ADS (Fuel/Air Data Sensor) or a fuel flow sensor to measure actual fuel flow. Estimated fuel data, which does not require an F/ADS or fuel flow sensor, may be displayed for inactive flight plans in FPL mode. Measurement units available include: US gallons, Imperial gallons, Liters, Pounds, and Kilos. "track" - the station has acquired the signal, has successfully cycle selected, and is tracking the signal. The bottom line shows the SNR (Signal to Noise Ratio, from 0 to 99), the cycle data 1 (0 to 99), and the cycle data 2 (0 to 99). Cycle 1 data should be less than 50, and Cycle 2 data should be greater than 50. The greater the difference between the Cycle 1 value and the Cycle 2 value, the more accurate the position. Secondary status is displayed as "Bnk" (blink), and/or "SNR" (Signal to Noise Ratio). Secondary station status is used to determine if the signal is useful. The station may not be used if it is in a blink (BNK) condition, or the SNR is too low. The Master station is in cycle, the SNR is 8, and the Cycle 1/2 data is 48/51. LORAN1 GRI1 9940 MASTER CYCLE 08 48/51 SNR SYS Secondary Station Information The display below shows the signal information for secondary station W (Whisky). A similar display appears for each secondary station tracked by each Loran sensor. The top line displays the Loran sensor number, GRI number, and GRI identifier. [. . . ] At power-up, the NMC will use this location in trying to acquire signals. When the Apollo NMC has been re-installed into the aircraft, you may be required to enter the location and time. Refer to the Power-Up Sequence section for details. 340 Operating Manual Supplement for the Apollo 2002/2102 Keypad These pages supplement your Apollo NMC Operating Manual and includes information for use with the Apollo 2002/2102 Keypads.
