Rapid descent
For a fast and efficient descent the ADVANCE Test Team recommend
that you use either big ears (with open or closed trimmers) or the spi-
ral dive, depending on the circumstances.
Tip: Rapid descents should be rehearsed from time to time in
quiet conditions – then they won’t become an emergency
when
needed.
Collapsing the Wingtips (Big Ears)
Bring in the ears by pulling both outer A-risers briskly downwards at
the same time. This will collapse the wingtips, and this configuration
can easily be held, either by hand or by fixing the outer A lines in the
cleats (Vary-Grip-System). You can pull the lines further through the
cleats to increase the folded areas, and re-secure them. To reopen
the big ears either let go of the outer A-risers, or free the lines by re-
leasing them from the cleats with a light pull. The wingtips will open
by themselves, thanks to the BIBETA 4’s high internal wing pressure.
While in big ears the paraglider can be steered with the brakes, with-
out problem. (See also chapter ‘Big Ears System’.)
Caution: To avoid stalling only pull the A lines as far as the
markings on the Vary-Grip-System.
Caution: Don’t fly spiral dives with big ears applied. The in-
creased wing loading supported by fewer lines can cause
damage to the wing.
Caution: Be aware that flying with big ears puts you closer to
a stall. Don’t rely on the use of big ears with a wet glider –
there’s more information on this in the chapter ‘Flying with a
wet
paraglider’.
Tip: If you need to come down fast for passenger reasons, or
to fly away from a danger zone, we recommend the following
method: Apply big ears and pull the lines in to the marks on
the Vary-Grip-System. Then accelerate the glider using the
trimmers, as far as conditions will allow. In this configuration
the BIBETA 4 comes down quietly, almost like being on rails.
Info: In the fully accelerated state the big ears do not open by
themselves, because of the high airspeed and raised stag-
nation point pressure. Help the opening with a brief but de-
termined pump: i.e. pull the brakes down wthin two seconds
to full arm’s length and release again.
