sections but also incorporates several real world tutorials which should help you get the most
out of your ClearNav. Please don’t be intimidated by the large size of the manual. The manual
includes many icons and graphics which help clarify things, but they take a lot of space – making
the manual appear extra long. It is really a pretty quick and easy read.
• Play with the ClearNav in Simulator Mode
The ClearNav Simulator is a great way to play with the ClearNav on the ground. It allows you to
fly the little glider on the screen around your local gliderport. You can turn, adjust the speed
and even bump the altitude up and down using the remote control. We recommend taking it
for a spin all the way around several tasks in the simulator before using the ClearNav in the
glider.
1.5.2 Fly Safely
It is very important to keep your eyes focused outside the cockpit as much as possible. Do not “play
with” or configure the ClearNav while in flight. Learn to use the unit and configure it to meet your
needs while safely on the ground. There have been several instances of very near misses (one glider
nearly hitting another glider in flight) which were attributed to one or both pilots “playing” with their
soaring flight computers or soaring flight software when they should have been keeping their eyes out
of the cockpit looking for traffic.
1.5.3 Not a Certified Instrument
The ClearNav is designed to enhance your soaring flight. It is not intended to replace your certified
primary flight instruments. It is not a replacement for good judgment – which remains the
responsibility of the pilot. All calculations are only as good as the data used in the calculation. If
incorrect data is entered then incorrect information will be provided by the device. For example: If the
glider polar data is not entered correctly the unit cannot calculate accurate final glide information.
Also, the unit makes no attempt to warn you to avoid impact with the terrain – it assumes that you will
see and avoid terrain and other aircraft. Waypoint and airspace data is the responsibility of the pilot.
The ClearNav has no way of knowing whether the data in use is inaccurate or out of date. The maps
displayed by the ClearNav are designed to supplement (not replace) the use of aviation maps such as
sectional charts, etc.
