Installations of TSO C-129 authorized Apollo GX55’s may be approved for supplemental navigation only. The Apollo GX55 may be used as the primary navigation data display, however, other means of navigation appropriate to the intended route of flight must be installed and operational. It is not required that these other systems be monitored.

Navigation Basics Nav Pages Estimated Time En Route (Ete) ETE is to the current TO (destination) waypoint from your present position based on the current ground speed. The units shown are in hours and minutes, 00:00 to 99:59. If the ground speed is less than or equal to 5 knots, the GPS receiver does not have a valid position, or there is no TO waypoint, the ETE value will be shown as dashes.
Navigation Basics Range (Rge) The distance from your present position to the TO waypoint. Units can be set as either nautical miles or kilometers in the Nav Info section of the System functions (see page 103). Nautical mile units are 0.00 to 9.00 nm in 0.01 nm increments, 10.0 to 99.9 nm in 0.1 nm increments, and 100 to 9999 nm in 1 nm increments.

Navigation Basics Minimum Safe Altitude (MSA) MSA is calculated by taking the Maximum Elevation Figure (MEF) from the sectional chart grid that corresponds to your current position. In areas below 3,000 feet, 1,000 feet is added. In areas above 3,000 feet, 2,000 feet is added. In the example below, the current aircraft would be considered to be at 7,000 feet.
Navigation Basics around the course. The value will be replaced with dashes if there is no valid GPS position, the TO waypoint is blank, or the current position is outside of the database coverage area. In the example shown above, the MESA for the present position of the aircraft would be 16,800 ft.

While orbiting the earth, each GPS satellite transmits complex streams of data containing the operational status and orbital location of all the satellites in the system. The Apollo GX55 receives...
Introduction to GPS Navigation this data stream and processes the information to determine which satellites are “visible” to the receiver’s antenna. With this determination made, the receiver chooses satellites to calculate a position fix. Using information transmitted from three or more satellites, the unit can calculate latitude and longitude (usually abbreviated Lat/Lon);...
Introduction to GPS Navigation RAIM stands for Receiver Autonomous Integrity RAIM Monitor. It is a way a GPS receiver can detect when the signals it is receiving from one or more of the satellites are wrong. It does this by using more satellites than are required for a position solution.
MAP). Approach RAIM is provided only if an approach is loaded into your active flight plan and it is enabled. Remember that the Apollo GX55 is not certified for Approach operation. Terminal RAIM, or 1.0 nm alarm limit is provided within 30 nm of your departure and your destination airport (except when Approach RAIM is provided).
What does it mean when I get a “RAIM not available” message? If RAIM is not available, your Apollo GX55 may be capable of continuing to provide good accurate IFR navigation. What you have lost is the ability to tell if a satellite is sending bad data.

Introduction to GPS Navigation Satellite clock failures, one of the more probable failures, is more likely to occur on the older Block-I satellites, but this does not mean that it can’t happen on the newer ones. When a satellite failure does happen, it can result in undetected error of miles in the position if a receiver is using the failed satellite in its navigation solution.

Message Function Message Function Message function is responsible for warning the user changing conditions which require immediate attention. When a new message exists, the MSG annunciator flashes on and off approximately twice per second, until either the user views the new message, or the condition causing the message goes away.
Message Function The New Message page shows how many new Messages messages are stored. 1. Press MSG. Turn the Large knob to switch between New and Old Messages. 2 New Messages Turn Large Knob For Old Msgs 2. Turn the Small knob to view each message. The Old Message page shows how many old Messages messages are stored.
Message Function The following is a summary of the conditions that Messages cause a message warning, and examples of the messages generated for each condition. Special Use Airspace Messages Following is a list of the types of airspace messages which can be generated. All of the airspace messages become old messages after they are viewed.
