5 Fast descend with over 15ft/sec. Sink Rate
The P43 allows B-Line stall, spiral dive as well as big ears while using the speed sys-
tem for a fast descent with more then 15 ft/sec. sink rate.
5.1 B-Line Stall
The B-line stall is induced by grabbing the B-lines above the line connections and
pulling the B-risers down. The P43 will start the B-line stall after pulling on the B-
risers about 6 ½ to 7 inches. The B-risers can be pulled down the full length (without
also pulling along the A-risers). This will result in a sink rate of about 24 ft/sec.. To
come out of a B-line stall release
quickly and at the same time both B-risers. After the
release of the B-lines the P43 resumes flight again immediately with a gentle ride
and continues with a normal flight. If a deep stall occurs , the flight can be proactively
corrected as explained below under „Deep Stall“ (pressing forward the A-risers). As
a preventive measure we recommend generally to put your hands on the A-risers
after coming out of a B-line stall. Finish your B-line stall with plenty of distance to the
ground to have enough altitude in case you need to recover from a deep stall.
Attention: Wrong beginning or ending of a B-line stall can be very danger-
ous. Avoid under any circumstances following mistakes:
•
to slow coming out
•
Releasing the risers asymmetrically
•
Braking directly after or during the coming out of the B-stall
•
pulling to hard on the B-risers so that the A- risers are pulled along
•
Accidentally pulling on the C-risers instead of the B-risers (could cause a for-
ward spurt during recovery of the B-stall)
•
Flight practice to try to feel your way to a lift edge should always be done with
enough altitude, a reserve and if possible over water.
