How many Glider Rides in one day

During last August I was 1 week in another club where
people had asked for help for an intensive ride
session. Some other pilots were flying rides in others
2 seaters during the same time. The principle was short
flights in the morning (time to glide back from winch launch
at 400m, i.e. 5 min) and longer (~ 15-20 min) in the afternoon.
The ground crew was very efficient by preparing the next
passenger before the flight with an extra parachute before
the landing. Nevertheless, my best day shows only 10 flights.
The limiting factor was the retrieve time for the winch cables
(2 cables only). During some morning flights, I lengthened the
flight, as lift was already available and the winch was not ready.

12 aerotows before midday once.

First was at about 9:15. 4 Students each took 3 aerotows. Pupe and self
landed short, stayed strapped in and towed off from rest position for 3
launches then swapped to next pilot. All were just pre solo and we went
through full CB- checks before eacn flight, one got a 'challenging' rope
break ( the last launch of the series ) and then went solo later in the day.
( My first solo signoff )

In 110 degree heat in Arizona I did 12 acro rides in one afternoon and
managed to "talk" some passenger into no acro and just cruising around (so I
could rest). I was whipped, never got out of the plane. I think they
offered me one more acro ride and I gave it to Kirk. They sent a golf cart
out to carry me to the shade because they said I looked so pathetic leaning
on the wing. I actually was in good shape. I just must look pathetic.

Checking my scruffy old logbooks, on October 6, 1996 I gave 15
commercial glider rides at Turf Soaring: 1 acro in an ASK-21 (logbook
note says "She was a screamer but enjoyed it"!); 9 rides in my
favorite SGS 2-32 (the first was a "photo flight for the group",
whatever that was), and 5 more rides in a Grob 103A (which do not
appear to have been acro). At the time I was helping out as a part
time backseat stick actuator when groups from Phoenix resorts would
show up (40 or more at a time) for rides. OK in October, ugly in May
when the temps got into the 100's!

A month later (Nov 10) I gave 8 back to back acro rides in a G-103A -
that was a lot more work!

And my daily total is surely no better than average...

I don't remember any of those flights except for the screamer - she
was exceptional! I just love those 5 point harnesses...

It's a great way to build experience and time; and it is a lot of fun
most of the time - you meet some really fun people.

I know you Guys have given a lot of rides in one day but how many is the
most for one person?

Have done 25 in a day several times. But I was younger then.
Think most was maybe 28.
Now keep to instructing. Most days 10-15 is enough.

Any towpilot who performs over 30 tows in one day is
definately due the 'Iron Butt' award. Wow! The coordination
for such a feat had to be first class, including the
time spent for refueling the towplane. You must have
refueled at least three times, maybe four. And potty
breaks?

Amazing stuff!

I did 59 tows in 1 day during the Wind Fair at Tehachapi.

Max all time for Skylark North was, I believe, 61
on the same day by Ted
Hutter.

I am awed, and weak in the knees just thinking about
it. I'd better get this
60-year old body whipped into shape for next season.

You and Ted must have had some excellent cooperation
and well organized
ground handling of the gliders to keep moving at that
rate. How many people
does an operation like that take?

At its peak, Skylark North in Tehachapi had the most professional,
highly tuned logistics of any operation I have ever seen - before or
since.

Days like the wind fair (1,500 ft tows) consisted of 3 tow planes, 6-7
ride pilots, and the most superb ground crew I have ever met. This
crew consisted of some amazing people: Mark Laciura - a videographer,
Rick Thereau - flight test engineer, Kelly Breed - photographer, and
my personal favorite, Kris Wiggs - educator and my then girlfriend and
now wife .

The flight line had the appearance of an aircraft carrier deck at full
throttle. Line crew would refill water bottles, give out wet towels,
bring food and watch you carefully for signs of impending dehydration
and general stupidity. At fuel stops they would be waiting with fuel
hose and ground wire in hand. The pilot would roll out, hit the head,
grab food & drink, check the gas cap, and strap back in.

Bluntly, we rocked!

It was some of the most fun I ever had.

I recall in my past at Lake Keepit in Australia on one Friday doing 78
tows in PA25-235 and the next Friday I broke that record and did 82
tows. We were well organised on the ground with me dropping the rope
and the next glider would be ready to go and a ground crew would hook
on the next rope onto the Pawnee. This was done around May 20 which
was just before our winter so weather was cool and we started about
7.30am and finished 5.15pm which was near last light at this time of
the year. Previous day records were all around 50 tows and we have
never gone close to that record in more recent years. I believe you
could only do this in a Pawnee as it is relaxing to fly. I recall
stopping after each 12 flights for a little rest and this all happened
in 1987 - the good old days!!

This is not to you in particular, but queueing theory suggests that
maximum throughput of a queue occurs when the delay for each "customer"
in the queue approaches infinity.

So, how many gliders were typically waiting to be launched. and how long
did they have to wait?


I much prefer days like we had on Monday. There were 13 gliders in the
queue, but once they were all launched (and ten of them disappeared into
the distance) the towplane spent large amounts of time sitting on the
ground doing nothing.

Summer 2002 national championshipa at Lasham. 103 gliders launched in 62
minutes ( we were trying to get it under an hour)

I did 37 or 38 (can't remember exactly) winch launched circuits one
day.
