Overview

GTN Xi Series Main software version 20.10 includes the following significant changes:

New Safety Features

A Glide Range Ring on the moving map depicts airports within safe gliding distance, using your aircraft's published best glide speed and glide ratio (available for fixed wing only). Cyan arrows point to the best glide airport at any given time. For more information about this feature, refer to Section 3, “Navigation.”

For GDU 700( )/1060 PFD and GFC 600 Autopilot installations: GTN Xi provides access to the Emergency Descent Mode (EDM) function of the GDU TXi. In the event of cabin depressurization, activation occurs automatically for systems configured for cabin pressure monitoring. Manual activation is also available via the Emergency app or a dedicated external switch. For more information, refer to Section 6, “Abnormal Operations.”

New Features for Decreasing Pilot Workload

For dual GTN Xi installations: the Remote Radio Control feature allows you to use the knob on one GTN Xi to tune the COM and NAV radios on another GTN Xi. By switching between local navigator control and remote control, you can load active or standby frequency values to any GTN Xi radio from a search tab or waypoint information page. Refer to “COM” in section 2 for more information.

Selectable Knob Default: pilots can change the knob's default function from Page Navigation to COM Radio as needed to accommodate workflow. Refer to “COM Radio Setup” in section 2 for more information.

Selectable Startup Page: pilots can customize the default start page by selecting from a menu of available page options in the Systems Setup app. Refer to “Pilot Settings” in section 2 for more information.

Shortcut to View Charts from Active Flight Plan Page: pilots can view charts for a selected airport or procedure directly from the active flight plan. Tapping View Charts opens the Charts page for the selected airport, departure, arrival, or approach. Refer to Section 3, “Navigation” for more information.

Customized Page Shortcuts: rather than searching for pages, pilots can assign shortcuts to those pages they use the most. Page shortcuts appear on the bottom of the display in the locater bar and are accessible via control knob. For more information, refer to Section 1, “System at a Glance” and Section 2, “Get Started.”

Warnings, Cautions & Notes

WARNING

Do not use terrain avoidance displays as the sole source of information for maintaining separation from terrain and obstacles. Garmin obtains terrain and obstacle data from third-party sources and cannot independently verify the accuracy of the information.

WARNING

Do not rely solely upon Terrain Proximity data for terrain avoidance. Terrain Proximity is not a certified terrain awareness system. It is an aid to situational awareness only. Using Terrain Proximity data does not under any

circumstances or conditions relieve the pilot’s responsibility to see and avoid

terrain or obstacles.

WARNING

Do not use TAWS information for primary terrain or obstacle avoidance. TAWS is intended only to enhance situational awareness.

WARNING

Always refer to current aeronautical charts and NOTAMs for verification of displayed aeronautical information. Displayed aeronautical data may not incorporate the latest NOTAM information.

WARNING

Never use GPS altitude for vertical navigation, traffic avoidance, or compliance with any air traffic control clearance. The altitude calculated by GPS receivers is geometric height above Mean Sea Level and may vary significantly from the altitude displayed on the primary barometric altimeter. The barometric altimeter must be used to comply with all air traffic control clearances.

WARNING

Do not rely solely on VNAV guidance when navigating horizontally and vertically around user-defined airports. It is the pilot's responsibility to ensure separation from terrain and obstacles during an approach to a user-defined airport.

WARNING

Never use expired databases. Update databases regularly to ensure currency. Use out of date database information at your own risk.

190-02327-03 Rev. C Pilot’s Guide xi

Warnings, Cautions & Notes

CAUTION

Do not clean display surfaces with abrasive cloths or cleaners containing ammonia. They will harm the anti-reflective coating. Use a clean, lint-free cloth and anti-reflective lens cleaner.

CAUTION

Ensure that any unit repairs are made by an authorized Garmin service center. Unauthorized repairs or modifications could void both the warranty and affect the airworthiness of the aircraft.

NOTE

Foreign materials (i.e., moisture, objects) that come into contact with the touchscreen can prevent the unit from responding to touch commands. To restore functionality, wipe the screen dry and/or remove interfering objects.

NOTE

The COM application supports channel tuning for both 8.33 kHz and 25 kHz channels within radio-frequency range. If flying in a region where 8.33 kHz channel spacing is available, set the COM radio to 8.33 kHz to prevent the loss of any stored or recently used frequencies.

NOTE

Mounted along the fuselage, the COM transceiver antenna(s) of the equipment is (are) accessible only to aircraft maintenance personnel.

NOTE

All visual depictions contained within this document, including screen images of the system panel and displays, are subject to change and may not reflect the most current system software and aviation databases. Depictions of equipment may differ slightly from the actual equipment. Feature depictions may differ from actual unit features depending on configuration.

NOTE

The United States government operates the Global Positioning System and is solely responsible for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy and performance of all GPS equipment. Portions of the system utilize GPS as a precision electronic NAVAID. Therefore, as with all NAVAIDs, information presented by the system can be misused or misinterpreted and, therefore, become unsafe.

KNOB TUNING

The dual concentric control knob allows you to enter a standby frequency without opening the control panel. Pushing the knob toggles between radio and page navigation functions.

The selected STBY window turns cyan when the knob is used to change the STBY frequency.

If no action occurs, the selected STBY window reverts to cyan text after 3 seconds. This indicates it can be controlled by the knob.

When the STBY COM frequency is no longer selected, it reverts to white text.

FEATURE REQUIREMENTS

• Second GTN Xi series navigator: GTN 635Xi, GTN 650Xi, or GTN 750Xi

FEATURE LIMITATIONS

• Dual GTN Xi installations only

• NAV radio options available only on GTN 650Xi/750Xi

Some dual GTN Xi installations allow you to tune radio frequencies on both units from a single navigator. Control options allow you to switch between local control (local navigator only) and remote control (local and remote navigators).
