F5J Introduction
F5J - Thermal Duration Glider
with Electric Motor and Altimeter/Motor Run Timer

A rules proposal for F5J was considered and approved by CIAM in April 2011
and became an official FAI provisional class on 1 January 2012.
F5J was elevated to full official status at the 2016 CIAM Plenary Meeting effective 1 January 2017.

A good resource for F5J (particularly in the USA) is www.f5j-usa.com.

GliderScore 6.23 (and later) has the features to run F5J competitions to the provisional rules.

F5J is like F3J but with electric powered models.
In the F5J rules there is a height penalty based on "... the maximum altitude recorded from
the moment the model leaves the launchers hand until 10 seconds after the motor is stopped."

An F5J score is made up of
- one point per second of flight time, plus
- the F5J landing bonus, less
- the height penalty.

The height penalty is based on a reference height of 200 metres.
0.5 points per metre is deducted for start heights up to 200 metres.
3 points per metre is deducted for start heights above 200 metres.

As an example, a start height of 201 metres would incur a height penalty of 103 points.

There is no penalty for motor run, but there is a specified maximum motor run time.

With GliderScore the reference height and penalty points per metre can be changed for local competitions.

    - prevents entry of a landing score, and
    - time score is based on the target time.
