Beyond Tracy
Report on Possible Land-Out Locations
Site
Visits by Tom Anklam and Shamim Mohammed
May 19,
2018
We drove to 5 possible land-out
sites: Patterson, Crows Landing, Turlock Airpark, Westley - Valley Crop
Dusters, and New Jerusalem. A summary of our findings appear below. At the end,
I offer some thoughts on how intermediate XC pilots might use this to extend
flights out of Byron to beyond Tracy.
For each site, I comment on
suitability for aero and ground retrieves. As Shamim observed, there may be
NCSA rules that preclude an aero retrieve, even when it is technically
possible; from an unpaved, non-FAA approved runway, for example. So this needs
to be sorted out before assuming the aero-retrieves are possible for some of
the sites discussed below.
Patterson
Patterson is not a currently
functioning airstrip. It is located a short distance to the East of I-5. The
runway is oriented parallel to a large, white warehouse that is used as an
Amazon Fulfillment Center. The warehouse is white and should be useful in
locating the field. The paved strip is about 2300’ and oriented due
north/south. However, the quality of the asphalt is poor with numerous broken
areas (see photo). You could probably roll through the broken area that we
observed close-up. It was mostly small pieces of asphalt, not big chunks or pot
holes. Ramy says that he landed on the asphalt several years ago without
incident.
There are large open fields to the
east and west of the runway that are being used to grow hay. The day that we
visited, the field to the west was filled with hay bales and farm equipment.
Large flatbed trailers were parked parallel to the runway, just off of the
pavement. However, the field to the east was newly mowed and wide open. One
could easily land a glider there and Shamim commented that he would be
comfortable aero-towing from the field, although Club rules may preclude this.
Access to the field was open and it would be easy to bring a vehicle in for a
ground retrieve. The field is located within the Patterson city limits, just
off of I-5, so it should be easy to get an Uber pickup or other transport if
needed.
In summary, Patterson is potentially
a good land-out location, but you shouldn’t count on it unless you have very
current information on its status. The day we visited, the east field was wide
open, an almost perfect land-out spot. But tomorrow, it might filled with farm
equipment or have stacks of hay bales strewn about. Three or four weeks ago,
the adjacent fields probably were probably filled with high grass. Patterson is
probably most useful if you fly over it on the way out and then, if clear of
stuff and brown, hold it for possible use later in the flight. The other option
would be for someone to visit the site on the day of the flight and report
conditions back to pilots preparing to fly.

Crows Landing
Crows Landing is a former NASA test
center. It is a huge area with multiple, concrete runways. Should be a
no-brainer to land and tow from there, except that it is being used for other
purposes. The day that we visited, a local “Race Club” was using a portion of
the field for time trials; rendering a portion of the field unusable. Other
areas of the field were covered in orange traffic cones and appeared to be used
for automotive or motorcycle training.
Despite this, the sheer size of the
facility would seem to almost guarantee that a suitable landing site could be
found, even if some areas are off limits due to competing activities. It’s
obviously important to commit at a high enough altitude to get a good look at
what’s going on before selecting an area to land. It should be fine for
aero-tow (the runways are so huge that Shamim jokingly commented that he
thought that he could land his Citabria across the width direction).
We drove through an open gate the day
that we visited. However, the racing folks were using the same entrance, so
it’s not a guarantee that the gate is always open. The site is a little more
isolated than Patterson, but a ground retrieve should still be relatively easy
to arrange. I’m guessing that the site has cell coverage, but unfortunately
forgot to check.
From the air, it should be easy to
locate Crows Landing, because of its enormity.
Here are links to some photos from
the day we visited:

Turlock
Airpark
The Turlock Airpark is a private airstrip
on the west side of Turlock. A sign at the field indicated that you need to pay
a fee if you land there. The runaway itself is in good condition, although it
appears much shorter than indicated on the Sectional. Apparently, this is an
optical illusion because a check on Google Earth verifies that the runway is
about 2100’ long. There are displaced thresholds on both ends of the runway and
a useable length of 1800’ is painted in large numbers on the runway. However,
the full length would be useable by a landing glider. Orientation is 330 deg.
The name of the field and its elevation are painted on the runway; something
that should be useful in locating the field. There were signs at the field
indicating that it is also frequently used for RC aircraft operations. It was
all-quiet the day that we visited, but this remains a concern. It might be
possible to contact the RC Club and find out their schedule for using the
field.
Access to the site was open and it
would be easy to do a ground retrieve. Aero-retrieve to the north is not a good
idea because a busy highway and congested area is just off of the north end of
the runway; not so good for rope breaks. A takeoff to the south looks possible,
if wind conditions permit. As mentioned, the Airpark is within the City, so
ground transportation should be relatively easy to arrange. Ramy says that he
has landed there in the past and found it a good option.

Westley
– Valley Crop Dusters
As the name implies this is a
private, crop dusting strip. The runway is paved, about 1600’ long with
east/west orientation of 230 degrees. All of the other sites that we visited in
this area have north/south oriented runways and we noted that the day we visited
had a roughly 90 degree cross wind whereas the other locations had minimal
cross wind. The east end of the runway has multiple hazards including parked
aircraft and various structures and fences. The strip is about 105 feet wide as
measured between the two lines of trees. The day we visited, the weeds along
the edges of the runway were low and probably wouldn’t be a factor, as long as
you keep your wings from dropping during the roll out. But of course, this
could change as the growing season proceeds. Also, it appeared that there may
have been one or more high spots along the left shoulder of the runway that
could cause problems for a glider. You could probably land a 15m glider far
enough to the right to avoid these areas. But I would walk the runway before
using it as a primary land out option.
Not sure about doing an aero-retrieve
from there. Would need to discuss with the owners. Ground retrieve would seem
straightforward, again with permission from the owners. Overall, I guess
Westley could serve in a pinch. But uncertainties in useable width combined
with the likelihood for cross winds on post-frontal days, and potential for
high vegetation would likely dissuade me from relying on this as a primary
land-out. It seems that these concerns could be addressed if the owners of the
strip were amenable to us using it as a land out and allow us to more closely
assess it. But, as likely as not (maybe more so) they would resist the idea of
large winged gliders landing in the middle of their crop dusting operation.
There is another private field near
Westley, Del Mar. The runway is longer and more north-south oriented. We
weren’t able to locate it in the time we had available, but Ramy indicated that
Del Mar is a better option than Valley Crop Dusters.

New Jerusalem
New Jerusalem is a north/south
oriented, 3900’ asphalt runway, in apparently good condition, about 6.5 miles
east of Tracy Municipal Airport. It is surrounded by fences and locked gates,
no terminal buildings or other support facilities, and is accessed via an
unmarked dirt road that runs alongside an orchard. In other, words there is no
apparent reason for it to be there. However, it is there, and appears to be a
good land out option. Aero-retrieve appears to be straightforward.
As noted, the gates leading to field
were locked and it appears that a call to the Airport Manager is required to
gain access. Ramy says that the combination for the gate lock is in the Club
database (of course combinations change from time to time). The only indicator
that an airport is at the end of the access road is a small government sign
warning against unauthorized access into the airport protected areas. So for
these reasons, ground retrieval appears more involved than at other sites
visited.

New Jerusalem: Great land out site, with no
apparent reason for being there. Aero-retrieve appears the better option as
field is surrounded by locked fencing and access is road is unmarked and
non-obvious.

Beyond Tracy
For my glider, I typically set the
flight computer for McCready 4 and 1500 feet reserve in order to calculate
final glide arrival altitude. This results in a no-wind L/D of 28 compared to
book value for the ASW 20 between 40 and 43, depending on whose polar you
believe. With a 5000 ft cloud base and a 15 kt head (tail) wind component, I
calculate that I should be able to fly back and forth between land-out airports
separated by about 30 nm and maintain safety glide to one or the other (in
other words, the cross-over point to the destination airport, from 5000’, is
still within glide to the retreat airport). This compares favorably with the
distances associated with some of the land-outs that Shamim and I visited:
Tracy to New Jerusalem 6.5 nm
New Jerusalem to Crows Landing 18.7 nm
Crows Landing to Turlock Airpark 13.2
nm
Turlock Airpark to New Jerusalem 25.5
nm
So on a good, but not necessarily
epic, Valley soaring day, it should be possible to conservatively fly
Byron-Tracy-Jerusalem-Turlock Air-Crows then back to New Jerusalem, Tracy and
Byron (graphic of path below). As an aside, I’m not advocating that one should
slavishly fly point to point, regardless of conditions. But describing it this
way is simpler and illustrates how different land-out sites can be used in combination
to extend beyond Tracy.
Total point-to-point distance is 95
nm (176 km). The longest leg, Jerusalem to Turlock, could be done as a downwind
leg with the option to divert to Crows if, for some reason, Turlock didn’t look
good. Also, if Del Mar checks out, it would be an option on the Jerusalem to
Turlock leg.
Based on our site visits, I feel pretty confident about using Crows Landing. For Turlock, I want to do a little more homework on RC operations before committing to use it as a primary. The leg from Crows to Jerusalem flies almost directly over Patterson, so it could serve as an additional option, if site conditions are known with certainty.
A second option would be to fly
Byron-Tracy-Jerusalem-Crows-Gustine and then back the same way. We didn’t visit
Gustine, but my impression is that it’s a legitimate airport, suitable for
landing out. This circuit would be better when lift is limited to the hills
west of the Valley.
I would consider completing either of these circuits the
makings of a darn good day and a step forward in terms of flight complexity and
management compared to what I do now out of Byron. I suspect some of my fellow
early career XC pilots would agree.

One possible “Beyond Tracy” task. Total distance
is about 95 nm. Longest leg is about 25 nm.
