At first glance one might wonder why a folder of files is being dedicated
to launching a hang glider into free-flight; is not the challenge simply
solved:: "Just jump off a perch!" "Run off the hillside!"
"Jump into the wind!" "Leap!" "Run into the wind!"
"Get off that hill with that flying machine!" "Go, go, go....!"
And of course, if one needs help, then friends push you or the aircraft, steady
a wing tip while you run, or otherwise play a part in the launching sector of
your wonderful flying session.
Experience has shown that the challenge is not so simple. One wants to fly
free. A low-cost launch that results in safe free-flight is the target, even if
one chooses for the free-flight to last but a moment. Actually some
people really enjoy the launching sector as much or more than some extended
free-flight session; yes, just the launching can be full of adventures,
thrills, and challenges for mastery and creative innovation.
Hundreds of things can ruin a good day during the launching of a hang
glider; injury to the pilot and others can occur, even death, because of
launching problems. It is paramount to launch safely; instruction from
professionals is part of the program for safe launching.
Study is part of the program. Practice in the parts and in the whole of a
chosen launching method is key. Maintaining and respecting the parameters of a
launching situation is important. Is each part ready for the launch?
A fun way to proceed is to keep a logbook while taking tiny experience steps;
have fun learning the little things about your chosen launching method. And
know that any change of launching method will entail new special challenges; be
ready to be a newbie when making some change; talk up the change in your diary
logbook; talk the matter over with instructors and others in some group forum.

Parameters of a launching situation:
EnterData+
- Wind and air conditions (speed, gustiness, predictability, humidity,
temperature, indicators, upwind indicators, etc.
EnterData+ )
- Wing surface conditions (dry, damp, ice, dirt, loose, tight, clean, age,
etc.
EnterData+ )
- Environment (ground, obstacles, vegetation, upwind air current modifiers,
airspace, humidity, temperature, altitude ASL, permissions, etc.
EnterData+ )
- Hang glider and its parts Full mechanical check of all parts?
- Pilot (health, awareness, freshness, vision, hearing, communications,
clothing, harnessing, toilet, plan, experience, etc.
EnterData+)
- People (upwind, downwind, lateral positions, helpers, spectators, owners,
etc. )
- Chosen method of launching (see)
- Checking method (How does one make a check that all things are ready for
launch? Program? Instrument? Earphone? Proofing program?
EnterData+)
- What are answers to all the pertinent "What if...." questions?
- What is the total cost of a launching? $$?? Effort?
Time?
- What is the "green factor" of a launch?

Launching methods (LM) vary greatly:
- Flatland
- Short glides by foot-launching. Intent is to glide in ground-effect for the
free-flight portion of the flight. This can be done outdoors or indoors in a
gymnasium. Contests can be sporting here. Standardize the wing. Have
pilot-weight divisions. Who can launch by a launch line with a specified run
distance and touch ground or floor at the most far point? Who can clear a
certain bar height and land safely? Here we are not considering enhanced flying
(stored power, solar-powered, motor, engine, towing, rockets, slinging,
catapulting, pushes, floor-dropping, balloon-drops, self-kiting, etc.
EnterData+ This is a wing-assisted long-jumping or high-jumping form
of flying. This is a great running exercise. Yet the challenges to extend the
flight are ever there for intelligent and creative action. Some skill in
this method of launching is recommended as preparation for other launching
methods. One very well may need skills obtained herein for other situations.
There are some serious hazards and challenges in this form of launching. Wheels
and skis are to be considered. Adjustments to harnesses and hang lines are
important. Careful fitting of tether length is key. Consider the serious
circumstance of abrupt stops and "beaking" ---what will happen to the
pendulumed pilot? Is there a limiting line to the pilot's feet or hips? Is the
ground clear for wheeled rolling or for skid skiing? What wear is occurring on
the hang glider involved? Are these flights being recorded with notes and
comments?
- Long glides via artificial rising-air systems for short or long-distance
travel at low altitude or high altitude depending on the artificial system and
weather conditions.
