No... it means that companies with older Otters will be handing them down the supply chain when they get their new Otters. Skydiving is low on the supply chain, but Otters (like other things) will be rolling down hill. Birdshit & Fools Productions "Son, only two things fall from the sky."

jwalbright 0 #4 June 18, 2012 Victoria BC is as far removed from the main stream of Aircraft Manufacturing as any place can be? Isn't Boeing located just 2hrs south in Seattle. Don't get me wrong Victoria is a nice place except maybe the aquarium with their octopus show, but I would not think it's that far removed.Enter Funny thought Here Quote Share this post Link to post Share on other sites

Pretty common for planes to get some kludgy little vertical tail surface add-ons when floats are used or may be used. Floats add too much destabilizing vertical surface area ahead of the C of G.

Pretty common for planes to get some kludgy little vertical tail surface add-ons when floats are used or may be used. Floats add too much destabilizing vertical surface area ahead of the C of G. Correct. The extra forward area due to the floats increases the likelihood of a spin, and these vertical surfaces compensate for that....

totter 2 #15 June 19, 2012 http://airplanegroundschools.com/Seaplane-Skiplane-Float-Airplanes/seaplane-performance.html Here is a good explaination of why Auxillary Fins (or Seafins) are required with a float install taken from the above link. QuoteIn flight, the seaplane handles very much like the corresponding landplane. On many floatplanes, the floats decrease directional stability to some extent. The floats typically have more vertical surface area ahead of the airplane’s CG than behind it. If the floats remain aligned with the airflow, this causes no problems, but if the airplane begins to yaw or skid, this vertical area acts somewhat like a large control surface that tends to increase the yaw, making the skid worse. [Figure 5-2 The side area of the floats can decrease directional stability] Additional vertical surface well behind the CG can counteract the yaw force created by the front of the floats, so many floatplanes have an auxiliary fin attached to the bottom of the tail, or small vertical surfaces added to the horizontal stabilizer. [Figure 5-3 Vertical surfaces added to the tail help restore directional stability] Quote Share this post Link to post Share on other sites

Unfortunately if we look at what happened when Cessna reactivated their small aircraft production in the late 80's the value of used aircraft only increased.---------------------------------------------- You're not as good as you think you are.
