LightHawk Flight for the Delaware River Basin Authority, Dec 9, 2018


First off, you need to view this on a real computer with a real screen. Now put your flimsy iPhone away!

The Delaware River Basin Authority requested a LightHawk flight over the Mongaup River, from where it flows into the Delaware, upstream and following the East branch, to Harris. I have flown this as two flights, first recording the Mongaup River, then landing in Sullivan, KMSV, to switch cameras, and then towards the dump site (the client's second requested task) on a second flight. For the second flight I have mounted the VIRB Elite camera sideways (pointing towards the wing-tip), so that it records the point of interest when I circle a left turn over it -- this was good pivotal altitude flight practice (a required maneuver for the commercial pilot licence), haven't really done that in a while. With a camera mounted sideways I was then able to circle over a few other points of interest on the return flight: the dump site, passing alongside the Delaware River, the Tri-States point (NY, NJ, PA), the High Point Memorial, and I just happen to like VOR spotting, and the Sparta VOR was on the way home. For the videos below I provide only the clip segments of interest, as it may look "strange" when watching a video that is recorded "sideways".

Here is the video from the first flight (just the Mongaup segment -- to keep the download size small):

Here is the altitude plot for the return flight. You can clearly see my level altitude roughly 17:45 - 18:00 UTC as I circle over the lakes and follow the Delaware and then circle over the TriStates "Monument", and then the steep climb to circle over the HighPoint Memorial. You can see how low the tri-states points is and how "high" HighPoint is. And I find it remarkable that the highest point in NJ is ... almost not in NJ anymore. The low point and the high point so close together!



Here is the video clip for Tusten Mountain Lake, York Lake, and Wolf Pond:

DRBA Flight, normal speed, 1.9 GB

Here are the maps for that segment. I don't really fly too jerky, the lacking smoothness is due to GPS reception problems:



Here is the video clip for the dump site:

DRBA Flight, normal speed, 158 MB

The return flight had me pass directly over the Delaware River, so I flew a bit offset to the right of it and recorded it sideways, up to Point Jervis:

DRBA Flight, normal speed, 1.3 GB

Here are the maps for that segment:



Here is the video clip for the TriState monument:

DRBA Flight, normal speed, 696 MB

Here are the maps for that segment:



Here is the video clip for the HighPoint Monument:

DRBA Flight, normal speed, 930 MB

Here are the maps for that segment. I had to fly this a bit higher, because the mountain ridge on which the HighPoint Memorial stands is officially considered "mountainous terrain" by the FAA, but with a higher pivotal altitude also comes a larger turn radius, lower bank angle, and a slower turn rate. That's why these circles are bigger.



Here is the video clip for the Sparta VOR:

DRBA Flight, normal speed, 584 MB

Here are the maps for that segment:





Here are the flights on flightaware:

The first flight (cutting off most of the segment towards HighPoint):



The second flight (mind you, that was actually TWO turns over the TriStates Memorial :) ) And you see that a turn at higher pivotal altitude comes with a larger turn radius (the formula is v^2/11.3).

TriStates Monument (yes, they call that a monument). The red arrow points to the TriStates Monument, it's a slab of stone on the ground that you can get to through the cemetary (North of the highway) on the peninsula. They *actually* call a slab of stone a monument! The green arrow indicates a point near where the three states actually meet (in the water of the Delaware River). The "monument" says that they meet at the point where the "monument" stands, but it's not true. The real tri-states point is in the water, somewhere near the green arrow, but very close (only a few feet away).



TriStates Monument (at the tip of the peninsula, just protruding under hi 84. At the tip of this peninsula is where the Delware and Neversink flow together, and the tri-states point a few feet to the West (in the water of the Delaware River). You see the "monument" indicated with a red arrow, and the real tri-states point somewhere near the green dot. Mind you, the tip of the peninsula is in NJ, the highway is already in NY!



For a close-up on Google Maps, have a look at:

TriStates Point

As you can see, it gets even more bizarre: There is a NY corner in PA smack drab in the middle of the Delaware.
