What if there's a mountain straight ahead and a nice cornfield off to your
right. It's a fluid situation and you have to flow with it. If you aint thought of all the possible contigencies BEFORE HAND and WHAT should be the response when A, B or C happens and instead "go with the flow" and hope to make the right snap decision thats poor planning thats gonna bite you in the you know where someday.... take care Blll |

Thanks for the compliment George....
I get the impression some people just dont realise how bad a stall or spin near the ground ISSSS.....you might as well just drive a car off the top of a ten to twenty story building....its about as surviable..... Folks need to go to the online FAA/NTSB accident/incident database...it is EASY to use and full of good information.... You can read report after report talking about controlled forced landings in places other than runways and youll read about plenty of survivors and minor damage.....then read about stalls/spins near the ground.....and you read about fatality after fatality and totally destroyed aircraft..... If you wouldnt BET your life that you can do a 180 (or 90 or whatever) in the plane you in, with the load and weather conditions at the moment and the altitude your at...you better not do it....because betting you life is WHAT you are doing.... Another gotcha is trying to go SOOOO slow during your forced landing that you stall near the ground anyway....in this case a little fast is alot better than a little stall... take care Blll |

Transition to best rate of climb a bit above the altitude at which you could reasonably expect to be able to return to the field. If the rubber band breaks and you haven't transitioned to best ROC yet, don't even think about turning around; just try to hit the cheapest thing around as slowly as possible.

As I've thought more and more about getting my PPL and building a plane, it's these engine failure on takeoff accidents that bother me the most. It's been mentioned here that statistically, flying GA is about as dangerous as driving a motorcycle. Statistics can be misleading, of course. I used to ride motorcycles, and have done my share of "stupid" things, but the most danger in riding a motorcycle is more the stupid actions of other drivers, especially regarding the decreased visibility of the MC to other drivers. So to increase safety in driving a motorcycle, you constantly have to imagine your invisible and that every car that has the potential to intersect your course probably will, and act accordingly (in other words "ride paranoid") It seems that a pilot has alot of control over "most" of the risks of dying in his plane.... fuel exhaustion, flying into IMC, landing in crosswinds beyond pilot/plane capability... etc., but For awhile I've thought these were engine failure on takeoff were the most unavoidable accidents, since it's basically instant failure and can happen at any time in an engines life. I don't like feeling that there is a risk of dying that careful planning and/or technique cannot reduce. As I've done more research (yes I'm sure alot of this will be covered in PPL training.. but..) I've learned and inferred some things. Obviously, during takeoff is the time when the engine is under the most stress, that's why, I assume, a good run-up is done before takeoff, so hopefully if something is "about to fail" it will fail then and not on climbout. Your suggestion of best angle of climb, I believe mirrors my recent mental processes about the takeoff and engine failure risks. I assume that best "angle" of climb will give the aircraft the best compromise between rate of climb and engine output/stress? In thinking about engine choices for my (hopefully) upcoming Sonex project, this has lead me to lean more toward the (much) more expensive Jabiru 330, rather then the AeroVee or Jab 220. With more power available, the plane will climb to above my "no return" altitude quicker, and/or at a lower % power setting. I have communicated with one Sonex pilot who totaled his airplane after a prob hub failure (using a GreatPlanes VW setup, a faulty hub attachment that has since been re-designed) and an attempted turnback (roled the plane after a wingtip strike... fortunately lived to tell about it). Very scary stuff.... I was also taught in my first GA plane ride (sr-22) by a CFI to use every foot of available runway. We pulled onto a 5300 ft runway off the taxiway that was about 100ft or so from the beginning of the runway and he still turned, and looped around to use all of that 100 feet. He reasoned to me that in the event of an issue at takeoff that 100 feet of runway could be the difference between life and death, even though the sr-22 only needed less than 1000 feet to takeoff.... I know this is very basic stuff to this group, but in my very short time of "hanging around" 2 different small airports I have seen many folks jump in there plane without doing "any" inspection, takeoff with no runup, etc. I wonder how many of these statistics are a result of these breakdowns of procedure....? -- ET "A common mistake people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools."---- Douglas Adams |

ET wrote: Your suggestion of best angle of climb, I believe mirrors my recent mental processes about the takeoff and engine failure risks. I assume that best "angle" of climb will give the aircraft the best compromise between rate of climb and engine output/stress? Actually, best angle of climb tends to reduce cooling air to the engine. In some aircraft, it will produce higher CHTs and, consequently, more engine stress. This, by the way, is not the case with my aircraft/engine combo. It has two advantages. It keeps you closer to the airport during climb, so you may have a better shot at putting the plane down on airport property if things go bad while you're still pretty low. It also gets you higher by the time you reach those obstacles that most fields seem to have not far from the end of the runway. It also may reduce the noise level for people who live near the end of the runway. I've seen this claim in print, but several people here have argued otherwise. One certain disadvantage is that best angle of climb airspeed and flap configuration is rarely the same as that required for best glide. In my aircraft, I will be 13 mph slower than best glide, and I'll have 24 degrees of flaps in. I feel that, if the engine quits at, say, 300' AGL, I probably will prefer to have the flaps down to reduce the speed at touchdown, so all I really have to do is force myself to push the yoke forward and keep the speed up enough to avoid a steep descent rate. Best glide speed isn't real important at that altitude, IMO. George Patterson This marriage is off to a shaky start.

Old CFI/ATP/A&P here. If you want to be an old GA pilot, fly
paranoid. Assume mentally that the worst possible **** is going to happen at the worst time to you, so that when it doesn't you can be pleasantly surprised and the few times it does you will be so used to entertaining disaster that it won't really rattle you. Don't fly much at night in singles at first. It's dumb. When you do; keep a strip within gliding distance. Not doing runups after the first t/o really hasn't killed too many people. Most engine failures are on the first power reduction. Odd's are, the guys you see doing this know/have built their birds and they're comfortable skipping runups (just like you do on touch and go's.) But you always run up till about 800hrs. You need to engrain the same routine habit patterns. Don't fly on schedules. This, sooner or later will have you pressing bad weather or near sunset. Listen to war stories. Go flying a lot with friends who are real experienced. Old guys are really young guys who didn't get killed by their mistakes. And on the runway turnback issue, this is PURELY a PIC decision. There's just too many different environments, aircraft, pilot skill levels, and currency issues to make absolute rules on. Don't think about it until you've practiced it some with an instructor. Start high (1000 ft) on the first ones. Pay attention to the wind before you take off and plan which direction and altitude you will attempt the 180 on (we call this an "engine out briefing" in the airlines.) Lastly, remember that you're not going to live forever, so try to enjoy this general aviation insanity. They're probably going to outlaw it anyway in about fifty years!
