It's probably different for you as I realise you operate from a hard runway alongside powered aircraft. Bear in mind that we were trained by RAF instructors on a grass airfield used exclusively for basic glider training. The basic & advanced ATC gliding courses were intended as a basis for later training to PPL standard on powered aircraft in the Flying Scholarship scheme. It was a natural progression from gliding to powered flight. The principle of never attempting to turn back to the airfield in an emergency was instilled into us right from the start & remains imprinted on my little brain even now, more than 50 years later. (Turning back is still the cause of countless serious accidents with powered aircraft following engine failure on take-off. A significant number of these occur during simulated engine failures.)


We take off from the hard runway and land on the grass alongside... certainly wouldn't want to turn back towards the asphalt with traffic taking off! Grin  

 I figured as much about the reasons that a turnaround was taboo for you- there's something to be said for denying that option, so it doesn't become instinct when cadets move on to powered airplanes. But on the other hand, there is a height, in any airplane, where you might turn around safely, and given enough runway, you might land downwind with any airplane.

There are always exceptions to any rule but the FAA appears to agree with me that this is not a good idea. I found several articles on the subject including this one. The Impossible Turn (DOCUMENT FAA-P-8740-44 AFO-800-1283)

Ah yes, I was thinking for some reason that you were talking about the 21. It does look like even the 2-33 could out-perform it, but I guess this was good for cadets- they'd have to try harder and could not get in as much trouble. Grin The 2-33 was designed, I guess, to attract students who intended to quickly move on to something more capable (most US clubs and schools have a "glass" ship or two).

Modern training gliders are very advanced - & very expensive. I still think there might be a place for the good old flying brick.

Please don't misunderstand me. What I meant was an absolute horror at the thought of engine failure. Enough to cause panic in that situation were it to happen. Far too many people fail to understand that you do not need an engine or a whirling thing up front to remain airborne. An aircraft without an engine is a glider. It might not be a very good glider but the same principles apply. Once that mental block is overcome the situation can be dealt with calmly, instinctively & hopefully with successful results.


LOL.. yeah.. "horror" is a good way to phrase it. Even though you KNOW it's not really happening.. and KNOW the guy with you KNOWS what he's doing.. the very first time your instructor turns the trainer into 7:1 glider.. your brain is all over the place. You're still trying to get a feel for powered flight, and now you have seconds become a glider pilot  Cheesy  I'm not 100% convinced that's the best wat to do it.. and where glider requirements would really be adventageous.

The primary argument against it, are logistics. There simply aren't enough gliders, and glider-friendly airports, and tow-planes, and instructors; for every PPL aspirant to fliter through. Of course, that's a "chicken-n-egg" scenario. If it WERE required, there would be many, flourishing soaring schools. So... if the idea ever gained momentum, I'd be fully behind it. Alas, it's just not realistic.


A very good point. I think a compromise would be more emphasis on power-off flying of singles not just as an engine-failure drill, but as part of just learning the basics. But the mentality is that these powerplants are so reliable in general, so why dwell on that? I think that is a cop-out for two reasons: first, engine failures are extremely rare, but if you've been in denial about it and it happens, you will not do very well. Second, there are other scenarios that require you to shut down and get that thing on the ground ASAP.


 That reminds me of a gliding drill that I never heard of in powered training: the "benign spiral". This is done if things really go south, especially if you are suddenly incapacitated. While you can, you just apply full "up" trim (with no power in the case of a power plane), coax it into a shallow turn at Vbg or thereabouts, and try to relax. Needless to say, the "arrival", even in a glider, could be quite nasty, but sometimes you have to stop fighting. Even though I am definitely in the "fly the SOB into the crash" camp, that maneuver was illuminating.

Although it seems very passive, it is still a command decision, and in the event you've taken a bird in the face, or you are becoming overcome by a medical problem, smoke or hypoxia, or you've been sucked into a storm cell, it can be a very wise one, compared to trying to fly assertively when you are not able to do so. You won't exceed Vne, you won't get upside-down, and you won't stall/spin. I guess it could even be a option for VFR pilots who blunder into IMC and realize they cannot keep it together on the gauges alone (or IFR pilots who are suddenly faced with less tools than they can safely use). Definitely a last-ditch maneuver, but it might very well be better than "soldiering on" in some case, despite the uncertainty of where you will touch down.


But looking back, my instructors did have me do a fair number of power-off full-stop landings- this is enough to prepare you for the more common problem (power loss).  The real problem, as with stalls, etc. is that most PPs give that stuff up after their training.  Not much can be done about that, except to stress it more during flight reviews. My reviews so far focused a lot more on rules, regs, and nav than on envelope-stretching or emergencies.  I think reviewing CFIs really should get pilots out of their comfort zone as part of a review.
 Most useful (but fun) review I had so far was  in the Champ, as part of the tailwheel training... I had to really fly that thing conscientiously, nothing "rote" about it. And I will probably bundle my next review (due this September) with the PP- Glider check ride... that will also be very useful, I think. I'll be more at home (although it might not be in 94H at my home field), but it won't be "another BFR, ho hum".

I've found that the more I fly, the more I, "fear" engine failure. It's not a debilitaing thing.. it's just that more flying, means more time spent running that scenario through your head...every takeoff.. everty tank-change, every pattern entry. Not to mention that by the time you reach 1000hours, you'll have experienced some sort of engine issue.. or met a pilot who has had engine failure and survived it.. or have known a pilot who did not.  Cry  


Yes indeed... as time goes on, we don't fear it more so much as expect it more. Personally, I like to think the stats "reset" for each flight, but that nagging thought ("My number's coming up") still creeps in from time to time. When it does, that's the best time to run through your emergency checklists, or make that next landing a power-off. Grin

Quote:
I have no data for soaring.. but I do remember a survey that showed an inverse relationship between flying experience, and willingness to sky-dive   Huh


LOL- yeah, I know a lot of pilots who have zero interest in "jumping out of a perfectly good airplane". I'd still like to try it eventually, even though there is a more "helpless' aspect to it... you have your primary and a reserve, and that's it. I would imagine it's more likely that both will fail somehow than a wing will come off your airplane or glider (the only thing that would leave you totally helpless).  
But even skydiving accidents are rare, and they occur generally for the same basic reasons as any aviation accidents. So why dwell on it?

As it turns out, my glider instructor is also an experienced (but inactive) skydiver- I will probably seek guidance from him if and when I decide to get into that down the road.

My point exactly. However, I think I'm preaching to the converted.

No doubt about it, in the vast majority of cases, this idea does not work out. Primarily because with most light singles, you don't have a prayer if you are not at least at TPA, and secondly because maneuvering at MCA is not practiced much after the PP is earned.   

Most of these poor souls don't come to grief because they make the turn without putting a wing into a tree, yet still overshoot or drift downwind... invariably they stall in the turn and spin in.  A power plane will need a lot more altitude than a glider to do this, but the basics are the same: 1) nose below the horizon 2) coordinated turn, as steep as the airspeed allows, into the wind  3) slip/flaps/spoilers as needed.

That being said, my personal rule when flying with an engine is that if I am below TPA, I might turn a little this way or that, but going back to the runway is not an option.  I've tried "the impossible turn" at a safe altitude, and while it's surprising what the average Cessna can do, it's not worth it close to the ground. It's a lot easier to do a good job of turning engine-out with minimum alt. loss, and without stalling, when practicing than it is to do it when the fan quits right after takeoff!!    Shocked

Besides, if there is traffic departing behind you, even if you pull it off- what then?   Roll Eyes  There's the rub, even if you are really sharp and manage to turn around and get lined up.  At 47N, there is the option of the grass... but there are also good spots just beyond the boundaries that don't involve hairy low-altitude turns or creating a hazard to others. So I wouldn't even consider it. If I have 1000 feet or so (in a 172 or similar), I think I could turn to join the downwind and at least make a 180 to land halfway down the runway, into the wind. But again, there's traffic to consider. They could yield, but it would be risky.

So I agree that in most cases, it's best to head for a place you can see, with as little maneuvering as possible. Those engine-failure scenarios usually work out much better. Wink

Of course, it's situational.. and engine failures on departure, ending in other than off-field landings, should be limited to an airport environment in which you are very familiar.

That said.. this is my engine-out scenario; for the airport I fly out of often,,  KOSU.  The main runway is +5,000'. Under standard conditions, in a C172, you can be airborne by the blue line.. and with any reasonable head-wind; be a TPA by the yellow line. AND it's towered, so the chances of conflicting traffic are minmal.

Yeah.. that's the test-case scenario you see most often. It really shows how impossible a turn-back can be.

That manuever would never enter my head at most airports.. especially a short runway.

But if you can be at 300agl with still 1000 feet of runway ahead of you... AND have that nice secondary runway to turn back toward, it's quite safe.

Now.. if the failure matched the test-case, i.e failure at 300agl you might even get stopped ON the runway, without changing heading  Cheesy

Hadn't thought of the intersecting-runway scenario... a good point. But boy, you'd better have the altitude, and you'd better not screw up the turn. It's like I said- most of these accidents are from screwing up the turn, usually after hesitating before acting. Has little to do with whether or not they could have made it to a runway or any suitable spot.

Right... runway length, wind, and aircraft type make a difference.
At KSDM, on the 8000-foot runway, with a Champ you could take off and land several times, and I once aborted from about 200 AGL (stuck pitot cover) on the 3100-foot runway and landed with room to spare.

When I'm bored.. I can take thread-hi-jacking to new levels  Cheesy

I set up the C172 with 50% fuel and one occupant.. zero wind.


Takeoff and climb from 27L (5,000') to TPA (happened right where it should), pull the mixture and I made it to runway 05 with altitude to spare.

...




Then, takeoff and climb to 300agl, pull the mixture and try to land, same runway..  I over-ran the runway by quite a bit, but with any headwind, it woulda been fine.

...



Then, I went to a smaller runway and positoned myself for a takeoff roll having only 2000' in front of me. A 300agl (turned out to be 400agl) engine failure sure enough left me WELL short.

Big congrats, Sean. Sorry I'm a few days late on the uptake. Tongue If you're looking for some backseat ballast, feel free to let me know. Wink

No can do until I get the PP-G (which will be a while; I need 10 solo flights, then I have to rustle up the dough and schedule an examiner, etc.). Besides, I'm enjoying the solitude too much right now. Grin

But JP is working on flying from the backseat (preparing for his CFI-G), and we're all scared to fly with him-  er, I mean, he might be looking for someone for the front seat on any given day. Grin
