Welcome ...

Welcome to a new era of aviation navigation. Once again, II Morrow Inc. has set new standards in features and ease of use for the general aviation public. The Apollo GX-series of products are unequaled in providing the features, level of performance, and reliability that aviation users require. The Apollo GX-series sets a precedent that will be the standard to which all other avionics will be compared.

The Apollo GX50 is a full-featured GPS receiver that is IFR-certified for non-precision approach. The GX55 GPS receiver is IFR-certified for en route operation and designed to slide into your existing Apollo Loran or Flybuddy GPS receiver mounting tube. The GX60 combines the features of the GX50 with a revolutionary comm radio. The GX65 has the comm features of the GX60, but is not IFR approach certified and does not have the approach features.

You can be confident in knowing that you are the owner of the state-of-the-art in aviation navigation and communication. Our products are built to last and to satisfy your navigation needs.

Read the Introduction and Getting Started sections of the User’s Guide before you use your Apollo GX; these sections will give you the “rules of the road.” You can then refer to the other sections as a reference for the power you have at your fingertips with the most comprehensive navigation equipment available.

You will note that your User’s Guide may be missing some sections. This guide serves the entire family of Apollo GX products, but will only include the sections that reflect the features available in the product that you purchased. If you have an interest in the features and operation of the other models, see the section on Ordering Information.

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. The DoD has stated that 95% of the time horizontal accuracy will not be degraded more than 100 m and 99.9% of the time accuracy will not be degraded more than 300 m.

Installations of TSO C-129a authorized Apollo GX50/60’s and TSO-C-129 authorized GX55’s may be approved for supplemental navigation only. The Apollo GX50, GX55, or GX60 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.

Introduction

This guide describes the operation of the Apollo GX line of products. The GX50 and GX55 are GPS receivers. The GX60/65 models combine the GPS receiver with a VHF comm radio in a single package.

Apollo GX Features

The Apollo GX products are high performance GPS products with a high resolution moving map display configured in a 2 inch high by 6.25 inch wide standard package. The Apollo GX’s use a powerful, accurate 8-channel GPS engine designed specifically for high performance aviation use. The 160 by 80 pixel electroluminescent display uses an automatic intensity control to keep it easily readable in all conditions from direct sunlight to the dark of night.

Apollo GX Front Panel Description

A wealth of easy to use features serve the needs of today’s demanding aviation requirements. The large waypoint database has information about airports, VORs, NDBs, intersections, and special use airspaces that makes the Apollo GX an encyclopedia of aviation. It’s what you’d expect from II Morrow, the first to provide a database in a general aviation navigation aid. The database can be updated by simply changing the removable data card in the front of the unit. The database can also include 500 custom waypoints created by the user. Thirty flight plans can

Introduction

be saved with up to twenty legs for setting up custom tailored routes. The detailed Navigation information displays are also customizable and can be set to automatically scroll through the desired information. The Nearest/Emergency Search feature, invented by II Morrow (UPS Aviation Technologies), makes it easy to react to an emergency or change your active flight plan.

GX55

The GX55 is designed to be simple slide-in, pin-compatible replacement for panel-mounted Apollo Loran and Flybuddy GPS receivers. The GX55 connectors and antenna footprint are the same as the Apollo Loran and Flybuddy GPS receivers. The GX55 is TSO-C129 Class A2 authorized for IFR en route and terminal operation.

GX50

The Apollo GX50 GPS receiver possesses all of the performance features of the GX55, plus more. The GX50 is TSO-C129a Class A1 authorized for IFR non-precision approach operation. The GX50 uses the same tray size, but different connections on the back to allow for approach capabilities.

GX60

The Apollo GX60 combines the physical package of the GX50 GPS receiver with a revolutionary VHF Comm transceiver. All of this without the requirement for external cooling.

GX65

The Apollo GX65 possesses the same features as the GX60, except it is not certified for IFR approaches.

Display The display is a 160 by 80 pixel electroluminescent graphic display. A photocell is located in the top left corner of the front panel display. The photocell automatically controls the light intensity of the display from low brightness at night to high brightness during daylight operation.

Introduction

External Annunciators

When external indicators are installed, the Apollo GX will also provide an external indication when Parallel Track (PTK) is activated or a Message (MSG) is received. The GX50/60 also have external annunciator controls for OBS/Hold and Approach Active. “Hold” refers to suspending waypoint sequencing.

Controls The Apollo GX uses a variety of controls to manage the features. The controls include a power knob, dual-concentric knobs (called LARGE and SMALL), hard keys, and “smart” keys.

Power Knob

The knob on the top right side of the Apollo GX controls power on/off. Rotate the knob clockwise (CW) past the detent to turn the power on. Rotate the knob fully counterclockwise to turn the power off. Full rotation and the push-pull capabilities are only used in the GX60/65.

Power/Volume/Squelch Knob(GX60/65)

The knob on the right side of the GX60/65 controls power on/off, volume, and squelch test. Rotate the knob clockwise (CW) past the detent to turn the power on. Continue rotating the knob to the right to increase speaker and headphone amplifier volume level. Rotate the knob to the left to reduce the volume level. Pull the knob out to disable automatic squelch.

SMALL and LARGE Knobs

The dual concentric knobs on the right side of the front panel are used to select pages, edit characters and values, or other options. The LARGE knob moves the cursor and the SMALL knob changes characters. Either may change pages depending on the function.

Introduction

Keys There are two types of keys that allow you access to the functions in your Apollo GX: permanent “hard” keys and displayed “smart” keys. Seven back lighted permanent keys are used to reach the functions or perform other operations of the Apollo GX. The “smart” key labels are shown on the bottom of the display. There are two categories of “smart” keys: those available for the Map function and those available at all other times. Press the key below the label to use the displayed function. Press a function key once to go to the last page viewed or twice to go to its “home” page.

Hard Keys The “Hard” keys are the easy-touch, black, rounded keys with white lettering on the right side of the display. These keys include, NAV, NRST, INFO, SEL, MAP, Direct-To, and ENTER.

APT, VOR, INT, NDB, & USR

The map waypoint “smart” keys are present when the Moving Map pages are displayed. Press the “smart” key to control the display of the waypoint type. There are three selections possible: waypoint identifier and location symbol, location symbol only, and off. Pressing the “smart” key subsequent times will control which selection is made. Map waypoint choices are: Airport (APT), VOR, NDB, Intersection (INT), and User (USR).

A solid, reversed waypoint type annunciator above the “smart” key means the waypoint identifier and location symbol will both be displayed.

A bold outline of the waypoint type annunciator will show only a symbol on the waypoint location.

A thin outline around the waypoint type means that it is turned off and no information for that waypoint type will be displayed on the map.
