Q

What should be used if the tow rope is stronger than 200% of gross glider weight?

A

Weak Links. One on the glider and one on the tow plane.
Glider Weak Link rating = 80 - 200% of glider gross weight
Tow Plane Weak Link rating = 1 - 25% greater than glider Weak Link but no more than 200% of glider gross weight

A

Hands up with thumbs together

20
Q

PLS - Stop Operation

A

Wave arms above head

21
Q

A

Cut throat

22
Q

In Flight Signal (IFS)
Tow plane rocks wings

A

Glider releases tow line

23
Q

IFS - Tow plane wags rudder

A

Something wrong with glider. Check if airbrakes are deployed.

24
Q

IFS - Glider rocks wings

A

Tow plane should go faster

25
Q

IFS - Glider wags rudder

A

Tow plane should slow down

26
Q

IFS - Glider goes out to the left of tow plane and rocks wings?

A

Glider can’t release tow line

27
Q

IFS - Glider pulls tow plane tail to right

A

Tow plane should go left

28
Q

IFS - Glider pulls tow plane tail to the left

A

Tow plane should go right

29
Q

A tow line should never be connected to a glider unless ….?

A

A pilot is in the cockpit of the glider. If getting out of the glider, release the tow line.

30
Q

When should the tow line be attached?

A

After the checklist is completed.

31
Q

What should the tow pilot and glider pilot discuss prior to take-off?

A

An agreed launch plan. Direction/destination of launch, release altitude, glider pilot’s intention for flight (cross country, landing pattern, ….)

32
Q

What is the ground crew responsible for?

A

Air field clearance, pattern clearance slack take-up, wing runner, ready for take off signal,

33
Q

What signal does the glider pilot give for ready to take-off?

A

Flap rudder.

34
Q

How is cross wind take-off prepared?

A

Aileron towards upwind and rudder towards downwind.

35
Q

What does a cross wind take-off do to the glider?

A

It pushes the rudder downwind so that glider turns. into the wind.

36
Q

What position should the glider maintain during tow?

A

High position to avoid wake. Flying in wake causes drag. But not so high that glider pulls up tail of tow. Tow plane wheels on horizon.

37
Q

What are the steps taken for tow line release?

A
  1. Clear area
  2. Release
    Clear rope
  3. Turn right
  4. Maintain level flight
  5. Adjust trim
38
Q

How is slack line adjusted?

A
  1. Yaw away from the slack line
  2. Gentle application of the airbrakes followed by gentle retraction. Always re-lock airbrakes.
  3. If slack becomes excessive, or come close to looping around the wing, release the line.
39
Q

Why does slack tow line occur?

A
  1. Rapid pitch down of glider trying to recover from being high on tow.
  2. Turbulence
  3. Turning too far inside the tow plane
  4. Tow plane power reduction
