Flying The Crowded Skies

Having a whole mountain to soar over by yourself can be a glorious
solitary experience. Most of us prefer having at least a couple of flying mates up there
with us. At the other extreme, some competition pilots actually love flying in a dense
gaggle of gliders all sharing a thermal. But most of us dont really enjoy flying in
a thick swarm of gliders.
Paragliding is becoming popular here in the Pacific Northwest and
elsewhere. At my home site (Tiger Mountain in Washington) were seeing some real
problems from overcrowding. Some of the hang glider pilots have been flying here for
decades, and sometimes they understandably feel invaded by the hoards of paragliders. Long
term we need to open more flying sites, but meanwhile I think there are some easy
solutions that will ease some of the tension. First lets look at some of the
specific problems. Maybe these are familiar to you at your sites too:
- Mid-air collisions become more likely as more aircraft fly in the
same airspace. Its more tense and less fun.
- Boxed-In: Its stressful when a bunch of other flyers "box
me in" against the terrain.
- Thermalling versus Ridge Soaring: Tension mounts as thermalling
pilots and ridge-soaring pilots fly in traffic patterns that conflict with each other.
- Hang Gliders versus Paragliders: Tempers flare as hang glider pilots
and more and more paraglider pilots of varying experience levels all share the air.
Co-operation and harmonious flying is made difficult by differences between the mindsets
of some paraglider and some hang glider pilots, but also by inherent differences between
their respective aircraft.
- Landing Squeeze: The LZ starts looking dangerously small when two,
three or more gliders all descend to set up approaches and land at the same time.
- Launch Etiquette: the wind dummy is "coring up" and twenty
pilots all want to get into the air RIGHT NOW but some bozo has laid out his wing right in
front on launch, and he isnt even clipped in!
- Screaming and even violence in the LZs and Launches: some
pilots are used to crowded sites, but some are new to it and it sucks. Tempers flare as
pilots blame other pilots. No one likes to take the blame. Egos butt heads. The resulting
caveman behavior is just not acceptable.
Most of these problems and more are also happening at other sites
all over the world. Besides making flying more stressful and less fun, some of these
problems create dangers and may lead to injuries, fatalities and the loss of the
privileges of being allowed to fly at a given site.
So, what do we do about it?
I have a few ideas. (I hope youll write to this magazine to
fill in the holes in this list!)
Attitude
- Everyone is here to ENJOY flying. Were not defending our
country or our honor, were RECREATING. So dont get too serious. Keep a light
heart.
- We all share the same privileges of flying at a site, no matter what
kind of aircraft, and no matter how much or little experience. (Pilots must still meet
sensible minimum requirements for some sites.)
- Start with respect for your fellow pilots. Assume they care as much
about safety as you do. Give the other pilot the benefit of the doubt, and stay calm as
you discuss incidents. Confrontation closes minds, respect and cooperation open them.
Becoming defensive loses a valuable chance to learn. Dont assume your point of view
is the only correct one.
- Wake Up! Go ahead and indulge those profound feelings you get from
flying, but above all else stay alert and aware of everything in the air around you. You
are flying, and flying demands your responsibility and awareness.
- Never put your lust for lift ahead of safety.
- Mental Preparation: challenge yourself to identify potential
problems way ahead of time, and plan contingencies. This will help avoid panic when things
go wrong fast. At every moment, ask yourself "What would I do if..." ("What
would I do if the paraglider 30 feet above me hits big sink? Takes a left collapse? A
right collapse?" "What would I do if that guy continues his turn without seeing
me?" etc.)
Skills
- Fly under the radio supervision of an instructor until you have the
required minimum rating for the site youre flying. Dont jeopardize others by
flying without this qualification.
- Clear Your Turns. This means turn your head to look where
youre going before you start to turn your glider. Looking 90-degrees to the side is
not enough you must look 135 180 degrees behind you to be sure your turn
will not create a hazard even if you have the right of way.
- Learn and obey the rules: the cardinal rule, the rules of the ridge,
and thermal rules. (See sidebar.)
- Be Aware. Your life depends on knowing exactly where all the
aircraft around you are at each moment where theyre heading, and how fast.
Look around and tune in. Dont be caught off guard.
- Make eye contact. Other pilots need to know whether or not you see
them and are predicting their actions. Turning your head helps.
- Respond Early and Obviously: If you dont have the right of
way, dont wait until the last moment to begin your yield actions. Try to turn
gradually not abruptly. Give others clues about what youre going to do, and time to
alter their course smoothly. Hang gliders fly faster than paragliders if we
paragliders dont yield early enough when a hang glider has the right of way, the
hang glider is forced to yield to avoid an accident. The hang glider pilot gets
justifiably angry. Do your part and yield early.
HANG GLIDERS VERSUS PARAGLIDERS
Hang gliders and paragliders often encounter some problems when
they share the air together. This might be an understatement sometimes the rift
between the more hotheaded members of the "airbag" and "plumber"
communities makes the feud of the Hatfields and the McCoys look like a group hug by
comparison.
Understanding some basic differences and correcting some bad habits
can reduce conflict and tension. The big differences between hangs and paras are speed,
turning speed, aircraft size, and pitch control. Lets look at these.
Tandem and competition flying aside, most recreational paragliders
generally fly at remarkably similar speeds with each other. They have a relatively small
range of speeds, and they rarely pass each other, so they often dont readily
empathize with those who pass them.
Hang gliders generally fly faster than paragliders, forcing the
hang gliders into a passing situation all the time when flying with paragliders.
Passing someone requires more care and responsibility than being passed by someone else.
Paragliders generally react slower to turn initiation, and rotate
more slowly into the turn.
These speed and turning differences often result in a paraglider
feeling like they cant react fast enough to stay out of the hang gliders way,
so some pilots sort of resign themselves to watching the hang glider do all the collision
avoidance.
This isnt fair, its just something I see happening.
Paragliders need to understand this, to fly more courteously, to do what they can,
especially initiating avoidance actions early. Hang glider pilots need to recognize these
differences and not expect paragliders to do some things that only a hang glider can do.
The worst paragliders go so far as to blow off the right of way
rules, partly because honoring them would require a lot of foresight and initiating
yielding action much much earlier than they are used to. Some use this as an excuse to
rudely hog the lift. This is unacceptable behavior and needs to change.
Next difference: hang gliders have pitch control, paragliders
really dont. This gives hang gliders a bit more liberty and options (and therefore,
responsibility) when sharing the air and avoiding collisions.
Last difference: when I fly my tandem paraglider, my aircraft is a
whopping 33 feet tall. Ive often seen hang gliders flying very close together in a
thermal they love it. Theres just no way to put a 33-foot tall slower
paraglider in there without causing some disruption. Ill avoid it if theres
other lift to be had, and when I cant avoid it we both need to just calmly work
around each other.
We have a choice: we can keep our "clan mentality" and
complain about each other, or we can just adapt and go fly and make the best of it and
enjoy it. If you really want to understand another type of aircraft, talk to someone who
flies both and is passionate about it. I have a standing offer to give any rated hang
glider pilot a tandem paragliding flight, free of charge. I hope well all benefit
from more understanding and some courtesy.
RULES FOR SHARING THE AIR
CARDINAL RULE:
Do not force another pilot to avoid a crash.
Keep your options open and actively avoid the crash yourself, no matter who has the
"right of way."
RULES OF THE RIDGE:
- The pilot with the ridge on his/her right has the
right of way.
- Yield to any pilot turning away from the ridge.
- Any pilot lower than you has the right of way. Yield
to anyone below you.
- Maintain at least 50 feet of separation in all
directions from all other aircraft.
- Passing: WARNING: This rule varies between sites and
even between aircraft types! Learn the local protocol before flying any site. At some
sites, faster aircraft should pass on the outside (away from the ridge). Be prepared to
yield in case anyone youre passing turns away from the ridge! It could happen
suddenly! At other sites, faster aircraft pass on the inside (between the ridge and the
aircraft youre passing.)
THERMAL RULES:
- Any pilot lower than you has the right of way. Yield
to anyone below you.
- First pilot in the thermal sets the turn direction
right (clockwise) or left (counter-clockwise).
- When people are turning in different directions (such
as when separate thermals merge), be flexible. Try to do what the majority are doing, and
dont switch directions often.
GENERAL RULES:
- When your path crosses the path of another pilot, yield to the
other pilot if he/she is to the right of your path.
- If youre on a head-on collision course, break right (turn away
to your right.) This is just like driving a car in the US your "lane" is
always to the right of oncoming traffic.
Note to Travellers: Some countries or sites use variations that
differ from these rules. When in Rome, learn how the Romans fly...
Thermal versus Ridge Rules
When thermallers and ridge-soarers cross
paths, who has the right of way? Some sites feature both thermal and ridge lift. If you
enter a thermal and can safely 360 or S-turn in it without disrupting traffic, go for it.
If its too crowded, let it go. If other pilots are turning in a thermal, dont
barge through in ridge pattern. Adapt to both the air and the aircraft around you. If
its too crowded at the "house thermal" or a known lift area, go check out
someplace else. Sometimes its better to explore an unfamiliar area and risk sinking
out.
Launch Etiquette:
- If others are waiting, choose a clear space well away from areas
used for actual launching and top-landing to prepare your wing and clip in. Then carry
your wing to where people are waiting to use the launch areas. (Paragliders: if needed,
just ask others to help you lay out your wing after youre clipped in.)
- If you dont intend to launch immediately after laying out your
wing, honor others request to "push": gather your wing and move aside.
- If someone else is trying to top-land while youre setting up,
try to use only space that isnt needed for their top-landing. (Sometimes
top-landings are emergencies!)
Landing Tips:
- Anticipate Rush Hour: if there are a lot of wings in the air, think
how crowded (and scary!) a small LZ will be if every one gets "flushed" at the
same time. Sometimes its wise to leave lift early in order to "beat the rush
hour" in the LZ.
- Vertical Separation: As you descend, look around. If there are other
gliders at or near your altitude, no matter how far away they are, youll likely be
squeezed as you converge on the LZ. If the other flyers dont beat you to it,
consider increasing your descent rate to gain some vertical separation. Do this early!
Talk to your instructor if you dont know how to safely descend quickly.
- Share the LZ: It can be tense but sometimes you just have to land at
the same time as someone else. If so, keep calm. Most sites have some standard landing
pattern if not, the "Aircraft Approach" pattern is strongly recommended.
Look all around! Inadvertently cutting someone off can cause an accident! You will
probably land side-by-side, so give your buddy room. Try to do a long straight final glide
instead of lots of low late turns. (This is easiest when there is no wind-gradient over
the LZ. Talk to your instructor!
- CONTINGENCIES: In general, always try to land in the LZ, but if the
LZ is looking really crowded, dont force yourself to land there if its not
safe! As a last resort, think about other places where you can safely land. Do this early
while youre high enough to have options. Consider checking out other fields on foot
beforehand so you know which fields are safe and unsafe. In an emergency, land where you
can.
- Clear the LZ: as soon as you land, secure your wing then immediately
move to the side to maximize open LZ space for your incoming comrades.
These things are all worthwhile, but ultimately a site can really
only host so many pilots at one time. If crowding brings on real accidents, it may become
necessary to impose a higher minimum rating for flying there. This may seem unfair, but it
is a practical way of dealing with a demonstrated safety problem and is common at numerous
sites.
There is one more solution that we all should put effort into:
opening new sites nearby. Im working on two sites near Seattle Washington:
Rattlesnake Mountain, and McDonald Mountain. More sites means less crowding, variety of
scenery, and maybe the ability to fly in more kinds of weather such as different wind
directions that render your home site unflyable.
Have fun and fly smart! I hope some of you wise birds out there
will write a letter to the magazine and correct all the errors Ive probably made in
this article!
