Glove Qualification Procedure - Garmin GTN 750 Pilot's Manual

Foreword
This procedure is used to qualify a specific glove for use with the GTN system
Getting
Started by guiding the user through a variety of tasks that use the touchscreen. Due to
differences in finger size, glove size, and touchscreens between the 6XX or 7XX

unit, the qualification granted by this procedure is specific to the pilot/glove and
6XX or 7XX combination. GTN 7XX and 6XX units must be evaluated separately.
Com/Nav
The GTN touchscreen uses capacitive touch technology to sense the proximity

of skin to the display. A glove increases the distance between skin and the display
glass and may reduce the ability of the GTN to detect touches. Therefore, when
Direct-To
selecting a glove for use with the GTN, thinner gloves tend to work better than
thicker gloves. Leather gloves and gloves designed to work specifically with
