Proposals for amendments to FAI Section 10.

This year, 2007, Richard Meredith-Hardy is the coordinating editor for Section 10 and its annexes.

How to submit amendments

Only CIMA delegates may submit proposals for inclusion here.  Anyone else should submit their proposal to their delegate first.  The full list of delegates is on the FAI website.

 

The amendment scheme will operate as it was done last year, all proposals from CIMA delegates should be sent to Richard Meredith-Hardy with:

1) The number of the affected paragraph (or where it should go, if it is something new).

2) The reason for the proposed change.

 

He will then assemble this into the document below, along with:

a) Comment from the S10 Sub-Committee

b) Comments any other CIMA delegates wish to make on the proposal.

 

Each proposal will be put to the vote in its exact wording at the CIMA Plenary meeting 16 -18 November 2007 on the basis of a YES or a NO.  It is not usual for the wording of proposals to be amended at the meeting itself.

 

The deadline for proposals for amendments is 23:59:59 UTC THURSDAY 27 SEPTEMBER 2007. After that, you will have to wait until next year....

 

Comment from the S10 Sub-Committee will be inserted before Wednesday 3 October when it will be passed to the CIMA Secretary for inclusion in the CIMA Plenary agenda.

PROPOSAL 1

Proposal title

Clarification of minimum leg lengths in closed circuit records.

Proposal from

Richard Meredith-Hardy, CIMA S10 Editor.

Existing text

S10  3.8.3 All legs of closed circuits must be of equal length but a deviation of up to ± 5% per leg is permitted in circuits of three or more legs.

New text

S10, 3.8.3 The deviation of up to ± 5% refers to a percentage value once the closed circuit has been divided into the number of legs flown, therefore:

 - 3 legs: all legs must be between 28.3% and 38.3% of the total length.

 - 4 legs: all legs must be between 20% and 30% of the total length.

 - 5 legs: all legs must be between 15% and 25% of the total length.

 - 6 legs: all legs must be between 11.6% and 26.6% of the total length.

Example: Each leg of a 300 Km 3 leg circuit must be between 84.9 Km and 114.9 Km in length.

Reasons

When the rules for records were re-written in 2006, the purpose was to clarify and simplify without substantially altering the principle objectives of any record. 

 

Pre 2007 rules said a closed circuit can be an out and return or a triangle, and triangles must be quite equal in as much as no leg can be less than 28% of the total distance.  The 2007 rules allowed more turnpoints for closed circuits longer than 100 Km. (up to 6), but leg length must still be more or less equal but with a permitted deviation of up to ± 5% per leg which was intended to be an insignificant 0.33% more severe than the existing 28% rule. 

 

In the current S10 3.8.3 there are several interpretations of how this deviation should be calculated, in other words the phraseology of the provision is unsatisfactory.  For people attempting records in 2007, guidance of how FAI / CIMA has chosen to interpret the rule was inserted in the notes at the beginning of the record claim form on the FAI web site. 

 

This proposal is therefore not a change but intended to formalize the guidance currently being used.

PROPOSAL 2

Proposal from

Richard Meredith-Hardy, S10 Editor

Proposal title

Clarification of altitude tolerance in speed records over a straight course.

Existing text

None

New text

INSERT:  S10 3.14.5  

The altitude at which the aircraft crosses the start line on the second run must be within 100m of the altitude at which it crossed the start line on the first run.

Reason

The amendments to S10 which came into effect 1 Jan 2007 inadvertently forgot that there are 2 runs associated with this record and to be like the pre 2007 rules, both runs must done at approximately the same altitude.   Guidance of how FAI / CIMA has chosen to maintain this for people attempting records in 2007 was inserted in the notes at the beginning of the record claim form on the FAI web site and says that they will interpret S10 3.14.2 to mean the SAME tolerance of 100 metres on the 1000m run-up applies to BOTH runs, not each run separately.

 

This amendment returns the record to what it was before 1 Jan 2007 in a clearer form.  The current guidance can be removed from the notes in the claim form.

PROPOSAL 3

Proposal from

Richard Meredith-Hardy, S10 Editor

Proposal title

Clarification of laps in closed circuit records

Existing text

None

New text

INSERT:  S10 3.8.6 

A closed circuit may only be flown once.

Reason

The amendments to S10 which came into effect 1 Jan 2007 inadvertently omitted that the pre-2007 rules did not allow multiple laps of closed circuits in closed circuit record claims.

 

Interpretive guidance was placed in the claim form notes early 2007 making it clear that adding together the combined distance of multiple laps of a closed circuit is not acceptable in a closed circuit record claim.

 

This amendment returns the record to what it was before 1 Jan 2007 in a clearer form.  The current guidance can be removed from the notes in the claim form.

PROPOSAL 4

Proposal from

Richard Meredith-Hardy, GBR Delegate

Proposal title

Exceptional units of measurement in timing.

Existing text

None

New text

INSERT:  S10 5.2.7 

Exceptional units of measurement.

Timed precision tasks in championships shall be rounded down to an accuracy of 1/10th of a second if manual timing is used, or rounded down to an accuracy of 1/100th of a second if an approved electronic timing system is used.

Reason

A problem arose about this at WPC 2007. 

 

Normal units of measurement as stated in S10 5.2.6 are HH:MM:SS.  Increments of less than a second do not exist in S10.   This is adequate for all purposes except some paramotor precision tasks where more accurate timing is desirable. 

 

1/10th of a second is considered about as accurate as can be done by manually timing with a stopwatch whereas electronic timing systems may provide greater accuracy.  In the absence of any approval system, "approved" is intended to mean "Approved by the International Jury", in other words if an electronic timing system appears to work to their satisfaction for the intended purpose then timing may be done to an accuracy of 1/100th of a second.

 

"Rounded down" is intended to mean the time which is taken is the time which is displayed on the time piece rather than it being artificially rounded later to a precision greater than permitted.  Thus if a manual time of 0:0:45.5655 is taken, the time recorded shall be 0:0:45.5 as was displayed on the stopwatch to the required precision and NOT rounded in 1/100ths of a second to 0:0:45.6
