Sharing the pattern with a UAV


Doug G.

Recommended Posts

It is interesting to note the nomenclature of these devices:

 

UAV - unmanned aerial vehicle - common industry term

UAS - unmanned aircraft systems - FAA term and the one that will be used in official communications

drone - ill defined term used by most media

RPV - remotely piloted vehicle - military term for a subset of UAS

 

There are probably more terms, and there are naturally nuances in and between the above terms. I use UAS.

No chase planes. They have been flying them from the Grand Forks (ND) AFB but they are looking to save money since the ground control training (as well as the missions overseas) are flown by the ANG in Fargo. They will use the standard pattern and be in contact with ATC. Should be interesting. Their performance in the pattern is pretty close to a CT.

I think they are settling on UAVRPS drones. :)

I think they are selling on

hmmm... from the FAA website:

"Because UAS technology cannot currently comply with “see and avoid” rules that apply to all aircraft, a visual observer or an accompanying “chase plane” must maintain visual contact with the UAS and serve as its “eyes” when operating outside airspace restricted from other users."

 

One of our forum members flies chase plane when drones operate outside of restricted space in Arizona.

There must be an exception for ground controlled (i.e. no satellite handoff) pattern work. The briefing we got was very thorough with ATC present, explaining how the operations would fit in with others in the traffic pattern. The even talked about what would happen if there was a loss of signal. No chase plane was ever mentioned. I have had a predator fly over me on final at the Grand Forks AFB there was no chase plane in sight. In addition, the border patrol uses them on a regular basis along the US - Canada border, not restricted airspace and chase planes would make no sense on the many hour missions.

I'll know for certain by Sept. if the schedule holds.

Even at the airbase in Grand Forks there is a permanent TFR (figure that one out) where you can enter by contacting civilian ATC for a transponder code after which they evidently "see and avoid" for you. The same will be done here with the UAV using a transponder and the piloting team in contact with ATC.

There are ground observers in place that communicate traffic visually to the operator. In the case of the UAS I operate I fly it visually like a giant RC model for takeoff and landing until hand off to the operator in the control station. Some will operate within a TFR using a observer until they obtain a IFR clearance and radar control. Most the time we operate at 18000 and above in class A so not a factor most the time. If we are lower outside of restricted and VFR beyond visual range of a ground observer we use a chase plane.

I suspect they will fly the pattern better than I do. :) (Although I don't do much pattern work locally - I go to les busy places.)

The ANG guy didn't say anything about an observer, but that would make sense since this week be for the initial takeoff flight training - the portion before the satellite control handoff - and landing.

At times they will leave the area for an MOA to the west.

I wouldn't worry Andy, they'll just be watching you from class A. :)

LOL.  

 

I'm not really worried about them being able to fly well.  I worry about situational awareness.  A human eye has about a 180° field of view.  A drone operator has about a 20-40° field of view, which is like us trying to fly with the windows all taped up except a narrow slit, more more accurately like us flying with blinder-style goggles on, since the view can be swiveled on a drone.

 

The real problem is traffic avoidance and awareness, which I'm convinced is about 50% of what ADS-B was designed to do: provide traffic awareness for UAV systems in the normal airspace system.
