Local Tasks

The following are a list of short tasks that can all be flown within gliding distance of Aboyne.

Tasks

Task Turn Points Distance Max. Loss Height Rqd
1. ABO-ABD-LOK-TAD-AB1-ABO 23 km 700' 2000' (6km)
2. ABO-LOK-ABD-TAD-AB1-ABO 25 km 700' 2000' (6km)
3. ABO-LOK-TAD-ABD-ABO 28 km 700' 2000' (6km)
4. ABO-BTR-TAD-AB1-LOK-ABD-ABO 48 km 1600' 3000' (12km)
5. ABO-AB1-BTR-ABD-LOK-TAD-ABO 43 km 1500' 3000' (12km)
6. ABO-AB1-BTR-LOK-ABD-ABO 42 km 1500' 3000' (12km)

Notes

  • The Max. Loss column shows the maximum height that can be lost between the start and finish lines (the 1% rule). For example, for Task 1 if the start line is crossed at 3200', the height when finishing must be no less than 2500'.
  • Those without XC permission must stay within gliding range of the airfield at all times. The Height Required column gives the minimum height needed at the furthest point assuming a glide ratio of 30:1. This is only indicative: flying into wind or through extended areas of sink will significantly increase the height required.
  • Watch out for controlled airspace over the Aboyne Bridge turn point - it's 3000' AMSL, 2500' AAL
  • Variations possible include choosing a different start/end line (e.g., Dinnet Bridge, ABD) or flying the task in the opposite direction.

Objectives

Things to practice and improve

  1. Setting a task in the Oudie
  2. Starting a task and passing turn points
  3. Finding and choosing thermals
  4. Selecting a height band to optimise speed (i.e. strength vs height: don't hog the thermal until the climb dies)
  5. Thermalling left AND right (otherwise you will miss half the thermals you encounter)
  6. Managing your flight (e.g., ensuring you are always able to return)
  7. Assessing weather, wind, areas to avoid (Low over lochs, lee of hills)
  8. Choosing an appropriate task for the weather
  9. Reviewing decisions and performance
  10. Entering a flown task on the BGA ladder
  11. Improving average speed

Things to Consider

  • Fly at best glide, not min sink, to cover more ground.
  • Keep a good look-out!
  • In weak conditions, fly gingerly.
  • Thermals may only last fifteen minutes.
  • Look for lift upwind of clouds, or up sun.
  • Small cu have lift directly under them.
  • The best lift is usually under clouds with flat bottoms.
  • Follow line of least sink.
  • Keep a good look-out!
  • Headwind = shorter range.
  • Tailwind = greater range.
  • Glider Performance
    • Discus or LS4 40:1 @ 55 kts
    • Being pessimistic, take 30:1
    • With no wind and no sink = 10 km per 1,000 ft
  • Keep a good look-out!
