Development of flight instruments for hang gliding has slowed in
recent years. One of the reasons was the formidable Flytec 6030 (also branded as
the Bräuniger IQ Compeo+) – in competitions almost every pilot had one. It was
the first instrument with everything you needed for hang gliding comps: good
task software; usable airspace; good total energy compensation (a must for most
HG pilots); and all the fancy task-related information like glide-to-goal,
height above goal, glide ratio over the ground etc. It dominated the scene for
over a decade.

In that time however, paragliding instruments have developed at a pace, leaving
hang glider pilots feeling a bit left behind. No longer! Enter the new Naviter
Blade, a dedicated hang gliding instrument encased in a beautiful aerodynamic
pod, with a variety of different mounts to clip straight on to your hang glider
and all the functions you could possibly need. Naviter have put a huge amount of
time and effort into making sure the Blade is perfect before releasing it to the
public. So what does it offer?

Air speed indicator coupled with total energy compensation

As hang glider performance has continued to increase, with some hang gliders now
boasting more than 21:1 glide angle, we now treat our glides like sailplane
pilots. Dolphining in lift under cloud streets and not stopping for lift unless
it makes mathematical sense. Pilots with an accurate Speed indicator and Total
Energy Compensation have an advantage here, and the Naviter Blade provides both
through a highly accurate pitot tube encased in the nose.

A very loud speaker

You can regularly exceed 100km/h on glide on a hang glider, and the wind noise
can be very loud. On many instruments I have flown with you feel the lift before
looking across to the vario to see you are climbing; you then slow down and
start to hear the instrument. Quite frustrating and I could never work out why
they didn’t just make the devices louder. Well with the Blade they did - it is
designed for someone who needs hearing aids! I could only go as loud as 80%, and
that was already a lot louder than anything else I have used. A simple but big
problem finally solved.
