5.1.4   Landing

Landing the Golden4 is very simple and should offer no difficulty. On your first flights you may 

be surprised at how well it glides. Take account of this when making your landing approach! 

Into wind, at about one metre above the ground pull the brakes down all the way. In nil-wind 

conditions, or if forced to make an emergency landing downwind, you may prefer to take a 

wrap of each control line to enable a more dynamic flare.

5.2. Rapid descent

Sooner or later every pilot will need to descend quickly. It might be because of a sudden and 

unexpected change in the weather, reaching cloud base and not wishing to enter cloud, or 

simply because you need to finish your flight quickly. Additionally, if where you are landing 

is thermic, it is often very difficult to land without using a rapid descent method. There are 

three main methods for achieving a rapid descent and they are: Big Ears, B-Line Stall and 

Spiral Dive.

Practise  these  manoeuvres  under  the  supervision  of  an  instructor  and  with  a  reserve 

parachute. Never compromise your safety.

5.2.1   Big Ears

This is the easiest technique for a rapid descent. Depending on how much of the wing tip you 

deflate, 3 m/s to 6 m/s sink rate can be achieved. While in Big Ears your sink rate and forward 

speed can be further increased by using the speed system. The Golden4 can be steered while 

Big Ears are in by means of weight shift.

Initiation:

 Take hold of the outer A-lines on both sides as high as possible and pull them down 

smoothly. Hold them firmly. The effective area of the glider is reduced equally on both sides 

of the wing. The size of the deflated area depends on how deeply the lines are pulled down 

(or on the number of lines pulled – one or two outer lines on both sides). Be sure to pull both 

sides equally.

Recovery: 

Under  normal  circumstances  the  Golden4  will  open  automatically  when  the 

A-lines are released. Opening may be accelerated by gently pumping the brakes (repeated 

symmetrical braking on both sides).

5.2.2   B-Line Stall

This is a very effective rapid descent technique. Depending on how far the B-risers are pulled 

down, the sink rate is between 5 m/s and 8 m/s.

Initiation: 

Take hold of the B-risers at the top and smoothly pull them down until the canopy 

shows a span-wise crease where the B-lines attach to the canopy. Your sink rate will increase 

considerably while your forward speed will decrease to practically zero. Don’t be startled 

when the airflow over the top surface is disrupted and the paraglider enters a parachutal 

stall without moving forward. It will soon stabilise above your head.

Recovery:

  On  releasing  the  B-risers  the  Golden4  automatically  returns  to  normal  flight 

without staying in deep stall or surging in front of the pilot. Let go of the risers smoothly and 

symmetrically.

CAUTION:

 Do everything symmetrically and at the same time. If the B-risers are released 

unevenly the canopy can enter a turn. If the risers are released slowly and very unevenly you 

could enter a spin.

5.2.3  Spiral Dive

The Spiral Dive is the most effective way of making a fast descent. Every pilot should be able 

to perform a spiral dive and one day you may need to. When in a Spiral Dive always stay 

aware of your altitude, which decreases very rapidly. The sink rate reached in a Spiral Dive 

can be more than 15 m/s. During the manoeuvre the pilot and glider will experience strong
