without substantially reducing the forward speed of the canopy. To engage big ears the pilot will need to
lean forward in the harness and grasp the baby A risers (one in each hand) at the maillon if he can reach
that high, keeping hold of both brake handles if possible. Pull the Baby A risers out and down at least 30
cm so as to collapse the tips of the glider. It is very important that you are using the correct risers when
doing this manouvre so the other A lines are not affected as this could cause the leading edge to collapse.
Steering is possible by weight shifting with big ears in. If the big ears does not come out quickly own a
pump on the brakes will speed things up.
Before using the big ears facility in earnest it is essential to practice beforehand with plenty of ground
clearance in case a leading adge collapse accurs. Always keep hold of both brakes in order to retain
control. Putting your hands through the brake handles so they remain on your wrists is a good method of
doing this.
B-Line Stall
This is a fast descent method and is a useful emergency procedure. With both hands through the brake
handles, the pilot takes hold of the top of the B risers, one in each hand, and pulls them down by around
50 cm. When Ynovar TWO this is very difficult to do, and the pilot may require the help of the passenger
in order to acheive this manouvre, especially if the passenger is heavier than the pilot. AB-line stall will
stall the canopy and forward speed will drop to zero. Make sure you have plenty of ground clearance
because the decent rate can be over 10 m/sec. To increase the descent rate pull harder on the B riser.
When you release the B riser the canopy will automatically start flying again, normally within two seconds.
Sometimes the canopy will turn gently when it exits from the B line stall. It is normally better to release the
B riser fairly quickly rather than slowly as this may result in the canopy entering deep stall. Always release
the riser symetrically as an asymetric release from a B line stall may result in the glider entering a spin.
This manoeuvre is useful when losong a lot of height quickly is necessary, perhaps when escaping from a
thunderstorm. It should not be performed with less than 100 m of ground clearance. (see also Chapter V,
part 1)
Spiral Dive
A normal turn can be converted into a strong spiral dive by continuing to apply one brake. The bank angle
and speed of the turn will increase as the downward spiral is continued. Be careful to enter the spiral
gradually as too quick a brake application can cause a spin.
Care should be taken when exiting from a spiral dive. Too pull out of a steep spiral dive always release
the applied brake gradually. A sharp release of the brake can cause the glider to surge and dive as the
wing converts speed to lift. Always be ready to damp out any potential dive with the brakes. A spiral dive
should not be confused with a spin.
It is recommended that when you exit from a severe spiral dive that you turn in the opposite direction in
order to avoid flying back into your own tip vortex, which can sometimes cause an unexpected and violent
collapse.
Trimmers
The Ynovar TWO is sold with special trimmers on the risers and a spare set of trim tabs, which can be
replaced easily when the original pair become worn due to excessive use.
Launching and landing is normally done with the trimmers in the middle position so that the risers are all of
equal length. The glider will come up easier in this configuration.In order to reduce the brake pressure in
flight the trimmers can be applied to the slowest position. Try to avoid using the slowest trimmer position if
you are flying near the bottom of the weight range (below 150kg all up weight). If you are near the top of
the weight range (over 200kg all up weight) it is better to always fly with the trimmers applied, except for
the take-off. Flying with the trimmers in the slow (applied) position helps to reduce the brake pressure and
makes flying with heavier weights nicer. The trimmers have a recommended weights and trim positions
printed on them to show the pilot the ideal The glider is certified for all weights and all trimmer positions so
these weight guides are simply a recommendation for best use of the glider.
