FRIDAY EVENING GLIDER CHALLENGE AT OLDFIELD

DIRECTED BY BRIAN BROCKWAY

The challenge runs every Friday evening from the beginning of May until the end of August, starting at 6pm.

The Challenge is open to any electric powered glider, with no sub-classes

For these events the access gate may be left open but must be closed and locked by the last person to leave.

We must phone the ATC to tell them that flying is about to start and that we would like to go to 500ft (150m)

Friday Evening Challenge Rules

What is the Challenge? To land your glider on the Oldfield grass patch as close as possible to the flight time set for that evening. Flight times are: May 4 minutes, June 4:30, July 5 minutes and August 5:30.

These are the general rules:

• The maximum height permitted is 400ft (120 metres) unless permission has been given by Bournemouth ATC for the 500ft (150 metres) limit
   
• Two attempts per evening may be flown by each flier.
   
• Models need not be launched by the pilot.
   
• All flights are to be timed from launch to landing (leaving the hand of the launcher to first touch on the ground).
   
• Timing is not to be done by the pilot (unless they are the only one present that evening!)
   
• The best score from the two flights will be carried forward each month. A maximum score cannot be added to that month. This gives those who cannot enter every week a chance to win.
   
•  Any landing outside the mowed part of the Club grass field shall not score points. Landing outside the mowed patch will be counted as one of the two attempts but gets a zero score.
   
• In the event of an unsatisfactory launch, a “no flight” may be declared and another flight may be taken without penalty, but flights under 2 minutes duration are not counted.
   
• Flights may be taken at any time after 6pm until dusk in order to count and need not start at 6pm
   
• Models should have a height limiter on board set to cut the motor at 100 metres AGL. Should a pilot not have a height limiter then 20 seconds “motor on” will be allowed, after which the motor must be cut. (Unless in general opinion it exceeds the height limit, when the motor must be cut)

• The score for each flight is one point for every second in the air. This gives a maximum possible score of 240 points during May if the model remains in the air for exactly 4 minutes.
  
  One point is deducted from the score for every whole second under or over the target time.
