Glove Qualification Procedure
NOTE:
This procedure is not authorized for completion during flight.
Perform all tasks while the aircraft is on the ground.
The touchscreen uses capacitive touch technology to sense the proximity of
skin to the display. A glove creates a barrier between the skin and the display
glass, potentially reducing the ability of the display to detect touches.
This procedure qualifies a specific glove for use with the touchscreen. Due
to differences in finger size, glove size, and touchscreen between the GTN 6XX
and GTN 7XX units, the qualification procedure is specific to the pilot/glove and
GTN combination. Multiple units must be evaluated individually.
Glove Selection Considerations
• Thinner gloves perform better than thicker gloves
• Leather gloves, and gloves designed specifically for use with capacitive
touchscreen devices, are often found to be acceptable
• To improve touchscreen sensitivity while wearing gloves, use the pad of
your finger instead of the tip during touch interactions
Glove Qualification Guidance
• Table 18-3 contains the tasks required to qualify a glove
• Table 18-4 contains tasks that are not required to qualify a glove, but may
limit how some functions are accessed while wearing a glove
