DS
contest will be run as scheduled
Pilot briefing in the Fei Ngo Shan Peak at 12:30pm
The Hong Kong Radio Control Soaring Society is
organizing a dynamic soaring challenge fest on 30 March, 2008. This is the first of its
kind in Kong Kong. Dynamic soaring is an extreme area of powerless
glider flying. The goal of dynamic soaring is to fly the model glider to
achieve extreme high ground speed by exploring the difference of air
speed in adjacent layers of air masses. Please check on
this link for detailed
explanation. The current world record of DS speed is over 300 km
per hour. The contest will be held in Fei Ngo Shan peak on the
east-facing slope. For safety reason we do expect that the onlookers as
well as standby contestants be stationed in a designated area far away
from the firing zone.
There will be two classes of contest;
an EPP foamy class and an open class.
The judging criteria are based on the
highest speed achieved. Detailed rules are given below.

Contest Rules
-
For safety reason, the contesting planes must
not have a sharp metal nose. CD will inspect the contesting
plane for its structural rigidity
- There will be only one plane on the DS
track at a time
- Each pilot has one minute to gain high
after launch
- Before one minute duration after launch,
the pilot should enter the track (judged by the plane reaching
the below-eye-level behind the ridge)
- Should the pilot fail to enter the track
within one minute after launch, he is disqualified with a DNS
- The pilot can have a maximum of 20
circles on the track
- Should he leave the track, re-enter the
track is not allowed.
- The fastest measurable speed during the
20 circles period will be counted as the score for a round
- Should the pilot leave the track before
20 circles are completed, the fastest speed on all circles
successfully run will be counted
- Should the pilot fly too dangerously
outside the designated DS track, CD can call off the run and
give him a DNF
- After completing 20 circles, the pilots
should leave the track and land as soon as possible, and the subsequent
circles will not be counted. Failure
in landing doesn't affect the result.
- Should he crash before the 20 circles are
completed, he will be awarded with a DNF
- There will be a number of rounds
predetermined and agreed by all contestants before the contest
- The fastest time in a round will be used
as a normalization factor for other pilots' times and the final
score will be calculated according to F3F type of scoring with
no discard
