ington6 0 #1 May 15, 2010 I know floats use up some precious useful load and add drag, but has anyone done it? is there any place to figure out the performance of a beaver on floats or a 206? Quote Share this post Link to post Share on other sites
JerryBaumchen 1,365 #2 May 15, 2010 Hi 6, It has been ~45 yrs ago now but I watched about 5-6 members of the Seattle Skydivers jump from a float plane. The photo was on the cover of PARACHUTIST 'back in the day.' Howard White: Do you have that issue? JerryBaumchen Quote Share this post Link to post Share on other sites
ington6 0 #3 May 15, 2010 Cool. Wondering how I can find the performance numbers for a beaver on floats? the floats must add a lot of drag but it would e damn fun to do jumps from a float plane Quote Share this post Link to post Share on other sites

ington6 0 #5 May 15, 2010 Wow thanks, . Well yeah, do you personally think it is reasonable to run tandems from a beaver with floats? The location is very remote and the extra cost could be passed along to the jumpers. Also, how many gallons per load do you think a beaver with floats would go through? Looks like they would have to be 10k jumps from sea level, hand cams, and maybe 4 tandems? or 3 with a fun jumper or camera flyer. Quote Share this post Link to post Share on other sites

totter 2 #7 May 15, 2010 A beaver with the cabin extention is about the same size as a porter (cabin dimensions). A beaver without the extention is about the size of a Cessna 207 (just a little wider). It will burn around 35-40 gph at max cont climb. The issue that you would have would be the tandems exiting the aircraft. The floats stick out about 2 feet on either side of the aircraft. You could not exit a tandem without hitting the floats. Second, the steps that go down to the floats are very narrow. (2 inches wide) with nothing to hold on to. A single jumper could climb down, but it would be impossible for a tandem.

JakGramley 2 #8 May 16, 2010 Have the student climb down to the float first, then the TM can climb down and hook them up. The exit should be easy then. Jack Gramley Computer Consultant Quote Share this post Link to post Share on other sites
hcsvader 1 #9 May 16, 2010 Well thats a simple fix, just build a slide the goes from the door to the floats and slide out of the plane. WEEEEEEEEEEEEEE Have you seen my pants? it"s a rough life, Livin' the dream >:) Quote Share this post Link to post Share on other sites
riggerrob 643 #10 May 16, 2010 Better yet, hire a Fairchild Husky, one of the few float planes that is easy to exit! Oh! They retired the last Husky decades ago???? But my buddies from Prince Rupert wax romantic about their jumps from the last Husky. Quote Share this post Link to post Share on other sites
ington6 0 #11 May 16, 2010 What about a 206 on floats? Easier exit? What do you think gph would be at continuous climb? Half tanks I think you would half enough fuel for two tandems, floats (not amphib), Quote Share this post Link to post Share on other sites
totter 2 #12 May 16, 2010 If you can figure a way for them to easily get on the floats or clear the floats from the door then just about any float plane can be jumped with a tandem. A slide may be a good idea. Just don't make it out of wood. Splinters would be a bitch. Quote Share this post Link to post Share on other sites
mdrejhon 8 #13 May 16, 2010 QuoteWell thats a simple fix, just build a slide the goes from the door to the floats and slide out of the plane.Technically that may work, just make sure you engineer for: - Wind blowing you off the side of the slide. (use slight curved lip, or very wide slide, or slide slanted towards the rear) - Use a downward-curved lip at end of the slide (Could even follow outer contour of floats), so that you gracefully catapult beyond the floats without snagging the reserve flap or hitting your head as your butt goes into freefall. - Aerodynamics, more of a consideration if slide is not completely flat. - Stowage or low-wind-profile mount. This may be tricky, especially if the slide is not completely flat. - Exit stability considerations after sliding on exit slide. - Liability considerations.

swovelin 11 #14 May 16, 2010 So you want to jump a float plane, eh? You really should contact Tom Sanders at Aerial Focus because he has "been there, done that" and he has the photos to prove it. I've attached a tiny thumbnail FYI. Quote Share this post Link to post Share on other sites
pchapman 279 #15 May 17, 2010 To figure out the performance of a plane on floats, it's the float plane community will know more than most skydivers... As for the "has anyone jumped" aspect of the thread, back in the late 90s there was a tiny local DZ that didn't have its runway ready yet, so operated the C-185 (?) on floats off a nearby river. It made group exits fun -- just line up standing on the float. The scary part was down at the marina where we boarded. You wanted to watch your step going from dock to float, when wearing a rig and 10 pounds of lead! Quote Share this post Link to post Share on other sites

dzjunky77 0 #18 May 17, 2010 I talked to a pilot that flys people back and fourth and I been flying with him for 5 years back and fourth from camp at Dull Island in a Beaver with floats in SouthEast AK. He didn't have a problem with me jumping from his plane and Beavers are slow enough to bail out of! just my 2 cents Quote Share this post Link to post Share on other sites

piisfish 140 #20 May 17, 2010 would THIS be considered as a float plane ?scissors beat paper, paper beat rock, rock beat wingsuit - KarlM Quote Share this post Link to post Share on other sites
riggerrob 643 #21 May 17, 2010 PBY Catalina is considered a "flying boat." Exiting the side blisters is much easier because you do not have to worry about tangling with struts or hitting floats. A few Catalinas have (aftermarket) airstairs under the aft fuselage. Quote Share this post Link to post Share on other sites
totter 2 #22 May 18, 2010 Thats a great picture! Remember though, the original poster is asking about tandems, not fun jumpers. Little harder to climb onto the float. Quote Share this post Link to post Share on other sites
