About Altimeters Now

From Pierre Chaussebourg
Answer to Allard
The problem to use the altimeters at these last championships is that altimeters rules have been used together with the existing rules concerning timing.

These rules are in conflict !

The traditional rules time an observed flight from launch to landing or to the moment when the model disappears from the sight of timekeepers.
The altimeters time a flight from launching to the moment the model stops to fly.
Personally, I think this last timing is better considering competition spirit.
The problem at these championships is that both timing were used together.
The international tribunal of sport would not accept that, and I do not accept it too.

In junior F1B, the « declared » winner saw his timekeepers time increased by 10 seconds with the altimeter recorded time and so he has been declared the winner by one second in front of the second competitor whose model disappeared behind a building, and so was still flying but had no altimeter.
You think this is fair play?

I do think that it was too early and illegal to apply altimeters use at these championships. Rules need to be modified and accepted by the CIAM plenary meeting first!

Tweaking the Maxes?

By Aram Schlosberg
World Championships contests have very long flight lines but with lots of models in the air. Contestants are typically very well prepared and it is not surprising that at least 50% reach the flyoffs.
. Before starting to tinker with how to reduce performance we should explore the notion of maxes in World Championships.
.First, if early morning conditions are sufficiently calm, why not raise the max to 6 minutes, followed by a suitable break for retrieval. Maybe even skip the following flight and only fly 6 thermal flights?
.Second, we frequently have flights just a shade over a 3 minute max. Why not raise the max to 200 seconds in the subsequent regular thermal rounds?

The combination of both would require 1560 seconds to qualify for the flyoffs. ///

A few more items
We think that most of you watched the events unfold from the official site but incase you didn’t here is where you find them
In each there is  MENU item with a pull down to select the next event you want to look  at.
When browsing the results the first thing you notice is the large percentage that made the flyoff.  And in addition the number that only dropped a seconds.  Very high standard.
The was the first Senior World Champs that allowed an extra team member if that person was a lady. Those flyers were well up in the results. For example in the USA Team F1B Flyer Aimee Raymond was the top scoring F1B flyer.  The hard work in preparation paid off.

There were some very close scores, the case mentioned by Pierre above had Florian JACKEL beating Elouan RIGAULT by just one second.  Notable performance by the slightly built Elouan because for junior F1B flyers upper body strength to control both the winding and direction of the launch is very important and is not usually well developed for an 11 year old.  Maybe  the genes and coaching  from 2019 World Champ Mickael helped .. But watch out dad Elouan  is not far behind and I’ll bet he probably asked for an altimeter.

The other interesting item was that although the ‘big name’ flyers such as Findahl, Andriukov and Babenko were there and in the fly off none of the winners  were as universally well know as Per, Alex and Artem and the like . Again an indication of the level of competition.

Farming and flying technology working together ? While there were a large number of sunflower field near the flight line some genetic breeding or tweaking has made today’s typical sunflower only about 1 metre high a few years ago they were close to 2 metres high. Less “energy” wasted on growing a bigger stalk and more spent on producing a bigger head with more seeds. On the model side the on board GPS units have finding model amongst the crops easier too.


Some important aspects of On Board timing

From Bernd Hoenig

First of all.
With all the discussion about the pros and cons of the decision to use the logger as a result. It is enshrined in the rules. But I want to make one thing clear. In Europe, very clear rules were imposed on model flying as to what we are allowed to do. And it is definitely not allowed to fly a model out of the pilot’s line of sight. It must be visible to the eyes without any aids. The German Aeroclub has long been with the Federal Aviation Authority fought in Germany so that we can fly in accordance with the law. Let’s not jeopardize that. These conditions can be further regulated very quickly.

As the organizer of the Eifel Cup, I don’t want to read out the logger either. The participants have to present this to the competition management themselves on their own devices. By the way, it’s also in the code Sportiv!

And the cost of a logger shouldn’t be talked about. The first available logger costs no more than each journey to a competition.

Some comments  or observation  from the techno editor

1. A possible addon to a “standard” on board timing device to satisfy some civil authorities and possibly address Elephant 3 – models out performing sites and time keepers, would be to include geo fencing in the standard timing device.  In this case the organizer provides the limit of where the model can fly and D/Ts the model if it flies out of bounds. Again more complexity but maybe better than the alternative and careful attention to the rules.
2. It would seem that fly out of sight is fairly hard to enforce and eye sight ability varies signoficantlyand I believe authorities are generally concerned about controllable UAS that can cause mischief.  Or maybe the thought of an uncontrolled UAS is worse?  I believe there is a F1A sportsman from the UK who is legally blind? How does he fit in?
3. There is no question that with onboard timer the concerns of the event organizer needs to be addressed. It should make it easier not harder. Maybe there is a big event organizer on the FFTSC to look after our (I organize a big event too) interests.
4. I understand that there are 2 approved altimeters , All-Tee is reasonably priced, MiniNeurone is more expensive because it does more things.  Again the FFTSC could come up with Budgetary requirements. Maybe we need to look for an angel or sponsor  who would fund the development of a reasonably  priced standard device
