in such wind conditions, I dare say that there are only very few DH8D pilots that would not select 1020 rpm for an approach.
This makes the aircraft much more responsive to power lever movements and allows for much quicker corrections of gusts. And besides that, it is formally required by our (not FlyBE) OM-B (among others) in turbulent conditions. The main downside besides a bit more cabin noise is that careful handling of the power levers in the flare is required. Even more so than with 850/min, ham-fistedly pulling them back will result in an immediate descent if already low on energy or encountering a performance-decreasing gust and may lead to a rather solid touchdown.
C195,
a typical duration for the DFDR recording is 25 flight hours. The FQAR (for flight data monitoring) records up to 320 flight hours.
