Tow Launch procedures

We have based our calls on the best available at the time, we have refined them after thousands of tows.

We now prefer to have a 2nd person making the launch calls.

Decide if you are doing forward or reverse launch. Forward is strongly preferred unless there is a solid breeze.

The benefits of forward launching for zero, low to moderate winds and cross wind launches;

    *The bridle is free from obstructions,
    *There is no turning required so the driver can be more confident of pilots readiness to launch if wing is fully inflated overhead and square with tow line.
    *The timing with the driver on the “all out” call is less critical, if you have held on and built up pressure the driver will have reached launch speed and pressure when you make the “all out” call
    *The tow pressure helps inflate the wing,
    *You are lifted off the ground with only a few steps.

Initially.
Advise driver of name, all up weight, and direction of launch.

call “Take up slack” (driver sets tension to a low level)

Forward launching
When ready call “Imminent, Imminent, Imminent“. (At this point the driver starts moving increasing speed while steadily increasing line tension)

Call “All out, All out, All out” when you can’t resist anymore. (the driver will already have reach launch speed and tension levels, this just ensures he watches for a safe launch)

Reverse launching
These are for comfortable conditions, if you are launching above 20 km/h you should have good tow skills and helpers on hand.

call “Imminent, Imminent, Imminent” (Driver accelerates towards launch speed)

Count slowly to three while vehicle gains speed. Inflate, turn and control wing

call “All out, All out, All out” when you have turned and the wing is controlled. (Driver only then increases the tension to a launch-able level)

On Tow
Nothing needs to be said but comments about climb rate or height gains let the driver know things are going well,

You can ask for tow tension to be decreased at the top of tow to reduce pitching with “pilot releasing”

It is important you call “pilot clear” after releasing so the line rewind can begin as quickly as possible to avoid ground obstructions.
