Peter, in the US our FAA considers a tethered gyroglider to be a kite, and since it's designed to lift over five pounds it is subject to Part 101 of our regulations. It could certainly be considered a "flight," and it could impart valuable experience in managing the cyclic, but the operator is not considered a pilot while the machine is tethered, and the time aloft cannot be logged for any official purpose.So ... if you do the same in a gyro with engine , and log it maybe you could get a record for the longest gyro flight in history, but is it technically a flightas it's still attached to the ground , yet the pilot does intend flying and the "wings" are giving lift any thoughts on that ?
Hey that sounds like it would work to me... take pictures for us Wayne?:yo:...
If I thought I could get away with it, I'd go to the near by California Air National Guard base and "kite" my soon to be completed gyroglider behind a C-130 that is performing a maintenance ground run! LOL Either that or go over to Warner Brothers in Burbank and "borrow" one of their "wind machines" LOL
...or just tether near a campaign event during election season and ride the wind as it's actually created!...and "kite" my soon to be completed gyroglider behind a C-130 that is performing a maintenance ground run!...
JR, I appreciate the confirmation that it's possible and agree it would be impractical everyday practice. I will confess that part of this mental exercise on my part is in laying some hypothetical groundwork for regulatory questions. If a gyroglider is ever to have a role in a formal transition training program, it may have to escape the limitations of FAR Part 101, and ideally move past Part 103 as well. I'm wondering about a full-on EAB gyroglider operating under Part 91. Even if transition training was accomplished without ever releasing the cable, just getting a new glider through a Phase I test plan might require demonstrating the capability for free flight, determining the few applicable V-speeds, etc.....I surprised John Potter at Farrington's place once long ago by pulling the power back and thermalling up several hundred feet in an 18A ("I didn't know this s.o.b. could do that", he said).
With no power at all, it's another matter, because you need really strong conditions...a rotary wing glider wouldn't offer much practicality.
I would submit that this depends on how big those gaps are, and how high you could ride the lift before choosing to leave it for the next area of lift along your trip. I'm told some of the ridge lift locations in our area can sustain climbs of thousands of feet if you can stay in the column....at 4:1 glide ratio the gyro will not be able to bridge the inevitable gaps in lift even in those areas blessed with perfect ridge conditions.
