She's calling it the WD40 for a reason. <BR/><BR/>Trix, your read into the WD40's early flap system is correct. It's pretty retarded, but you only have assymmetry protection for the left flap, and that only if it's full up or full down. It was subsceptible to split flap because the flexible shafts that connect the flap motor to the flaps were too thin for the aerodynamic loads at extensions beyond 30 degrees. You'll find many early WD40s have an AD on them that limits flap extension to 30 degrees. All in all, it was a poorly designed system, rather uncharacteristic of the WD40. The later "Calco" type system was a huge improvement.Sam Weigelhttps://www.blogger.com/profile/06332414897030323612noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1143239731983190122006-03-24T22:35:00.000+00:002006-03-24T22:35:00.000+00:00With the split flap thing and the anti-servo tab, ...With the split flap thing and the anti-servo tab, this sounds like a PA31 to me! You also need to remember from what fuel tank the heater draws from and how much you need to allow for it in your flight planning, that sounds like a regular question in ground school.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1143201800225436092006-03-24T12:03:00.000+00:002006-03-24T12:03:00.000+00:00Sounds like one of those things you'd have to be o...Sounds like one of those things you'd have to be on top of. Flap assymetry is a real bugger. Can I guess that you'll be flying a Saab 2000 or 340 of sorts... hmmAnonymousnoreply@blogger.com
