Secondly, this is 100 feet below the altitude I stated. IIRC, Vy is for a C172 is in the region of 65 knots - or best glide, and many pilots accelerate to around 70-75kts at 500 feet to get a better view forward, since best rate in many parts of the world isn't critical to maintain once you're above a couple of hundred feet. I can see you missed the point entirely. By the way, Vy is never at best glide (it is above that ~69knots in a 172) -perhaps you would like to revise what determines Vy? My point was to ilustrate the impossible turn with some concrete numbers instead of the handwaving BS that seems pervasive in this topic. Good luck on your first engine failure during climb out, if you turn back I hope you make it. but you'll have a better chance going straight ahead... Cheers . |

I said Vy for a C172 is *in the region of 65 knots* (I don't actually remember what it is off the top of my head, it's been 5 years since I flew a C172, but I do remember Vy being close to 65 knots). I do, however, remember that for an 'N' model C172, 65 knots was best glide and Vy was close to that number. (In fact a brief internet search shows it to be 70 knots, so if the pilot recognises an engine failure promptly, should not have to dive to regain airspeed as your scenario stated. In reality, your 'concrete numbers' are just as much handwaving: how many pilots seriously climb out to 600 feet at Vx? How many pilots would seriously spend 10 seconds doing nothing but talking on the radio when the engine has quit cold - instead of looking for a suitable landing site and navigating towards said site?) Good luck on your first engine failure during climb out, if you turn back I hope you make it. but you'll have a better chance going straight ahead... Actually, I did go straight ahead but with 4000 feet of runway remaining and a slow aircraft (C140), it wasn't exactly the hardest aviation decision I've had to make. If it happens again, I'll do what I think is prudent at the time. That might be straight ahead, it might be turn to some amount, and it might even be return to the airfield. I can't say at this point, and I won't be able to say unless it actually happens - just like one of our glider pilots did when the rope really did break at 200 feet: owing to the strong tailwind that he would have had on a downwind landing, he elected to land in a field instead, even though the turn itself was eminently possible and he could have made it to the runway. My friend who did have his engine lunch itself had the choice of a built up area, a busy beach full of people, or the airfield. He was at about 600 feet in a C150. If I had been in the same situation as him, I'd have done the same - try to get back on airfield property because it was the only thing flat not covered in people that was within range. I can not fault his decision. (He did better than airfield property, he did get it onto the runway). What I'm trying to say in a long winded way is that there are no prescriptive solutions. "Always land straight ahead" isn't always the right decision, nor is the decision to turn back even if you really can make the runway safely (in the glider example, the prospect of groundlooping into a barbed wire fence when the glider got below wind speed on the ground was a deciding factor to land in a field rather than on the runway). It depends on conditions at the time, how much altitude and airspeed you have, and what the terrain is like. -- From the sunny Isle of Man. Yes, the Reply-To email address is valid. |

Actually, if you're light or have a tailwind, best glide will come at a lower airspeed. in a manuever this tight you need every trick in the book at your disposal. Bertie |
