4.5.4.1 Thermalling
The optimum flap setting for thermalling is position 4 or 5.
Flap setting 4 is the normal thermalling flap setting. The optimum thermal
speed at maximum load is 110 to 115 km/h (57 to 62 kts).
When the thermals are very rough it is recommended to fly slightly faster
(120 km/h / 65 kts).
Flap setting 5 provides the best results in smooth thermals where
minimal centring is required. At maximum weight the best speed to fly is
108 to 110 km/h (58 to 60 kts) in this flap setting.
