Q: C-152 spin characteristics
I've spun my MiniMax (homebuilt) twice from 700'. Back straight
and level by 500'after one turn. Of course, I've also done the "water-ski" trick with it on the Ohio river. Bob Moore Mmmm. Gentle. Weren't you even a little bit nervous about that? |

(cockpit object falls under the rudder pedal or something) You might as well start thinking like a GOOD instructor right now :-) There should be NO "cockpit object" in the airplane with you in an aircraft you have prepared properly for giving dual in spins,ready to "fall under the rudder pedal or something". This of course is the right answer :-)) Altitude on the other hand, is also the right answer. Surely not 9,000, though? Bertie Nah. I never did spin instruction that high. Unless you're doing sustained spin mode research requiring multiple rotation deep into sustained modes, there's no need to go that high. -- Dudley Henriques |

Turns out you can search for "Cessna spin" in YouTube.com and see all kinds of great videos of people spinning 'em. One of 'em just shows the instrument panel so you can see when the spin develops (airspeed drops to zero) and see how much altitude is lost per second. Can also see the airspeed start to increase dramatically as the stall is broken. Cool! There's even chase-plane video of Cessnas doing spins. Some of those guys are starting at 5,000 feet indicated or lower, which seems insane. I'd think you'd want to start at 8,000 or 9,000 just for safety in case things don't go as planned. (cockpit object falls under the rudder pedal or something) Well, that can happen and has happened to a lot of people. But if you go up to 9 grand two up in a 150 you got another emergency anyway, cause you're out of gas! I'd be happy enough at five with a floor of three Bertie .....not to mention the fact that it might take you past the 100 hour to get up there :-))) -- Dudley Henriques |

It took forever. I also had a 152 up to FL130 on a very long x-country. Took a while to get there but it wasnt so bad because it was (very) cold. Bertie |

(cockpit object falls under the rudder pedal or something) Here is my primary instructor and her buddy doing a 52.5 turn spin in a A152. They count off the altitude and the spins. You can see the altimeter unwinding, and it's about 195 feet per turn, as Kershner says in his Aerobatics book. You can almost make out the airspeed in some frames which looks like it might be 40 or 50: Wow! It looks like they're losing ~ 1000 feet every ten seconds through most of the spin. http://www.youtube.com/watch?v=IsX2yGJ2Tn4 |

I should mention "securing the cockpit for aerobatic maneuvers" in the lesson plan/checklist. I watched a video once of some Blue Angels practicing when a team member had planted a sandwich in the cockpit of one of the other planes. The pilot executed a roll and you could plainly see the sandwich floating across the cockpit. Pretty funny but I don't think I'd want that happening to me while performing formation aerobatics. -- Mortimer Schnerd, RN mschnerdatcarolina.rr.com |
