As a low time pilot (150 hrs) I have been alarmed at the number of
recent incidents relating to getting trapped in clouds. In reading though some old posts on this forum, I have concluded that even though everyone has the best intention of never getting into clouds, it still can happen to even the most experienced pilots. I was encouraged to see that there were some viable options for getting out of the clouds alive, including the benign spiral, flying south by compas and using turn errors to maintain a heading with dive brakes, using GPS heading and groundspeed, and T&B indicators. From what was writtten, I don't consider a spin a safe option anymore, unless I was being pulled up into a large cell at 15 kts. So in an effort to keep my personal survival rate up to 100%, minimize pilot stress, and maximize my options, I am considering installing some type of bank angle indicator in the plane I fly (LS4a). I noticed the TruTrak spins up in 3 seconds, gives an acurate bank angle even if powered on in a turn, and uses relatively little power. Does anyone have an opinion about this instrument or others that would do the trick? My only criteria is that it helps me get out of the clouds alive. Thanks for any advice! |

I have a TruTrak installed for this purpose and it appears to be an excellent choice. It turns on in an instant and shows bank angle all the while your turning. It does not show pitch but for a sailplane the airspeed indicator will suffice. |

Best advice? Learn how to identify a cloud, then stay out of it.
Sounds absurd, but unless you have real IFR experience, then you should stay the legal limit away from the cloud. If you go gearing up your ship for instrument flight, then your going to find yourself pushing close, probably going IFR. Do this. Have someone blindfold you, then, while in a hallway in your house, where you can run for say 3 seconds, the time to spool up your little turn/bank, takeoff running full speed. Then report back to us. Think of the first wall or table you hit, as another aircraft in the clouds. That's how fast it could happen. All that crap about flying GPS headings, flying south/turn errors, all witchcraft. Don't subscribe to it. Learn the facts, and you'll hit closer to your 100% survival rate. Learning safety takes dedication. Don't take shortcuts! Have fun!

In reading though some old posts on this forum, I have concluded that even though everyone has the best intention of never getting into clouds, it still can happen to even the most experienced pilots. First, not every pilot tries to stay out of cluds. There are many (me included), who enter clouds by purpose and for the fun of it. Of course, we're appropriately trained and the glider is appropriately equipped. Second, those who want to stay out of cluds can do so. No, it cannot "happen to even the most experienced pilots" if you fly on the safe side. Of course, there are always pilots who gamble. I was encouraged to see that there were some viable options for getting out of the clouds alive, including the benign spiral, flying south by compas and using turn errors to maintain a heading with dive brakes, using GPS heading and groundspeed, Believing in these "vialble options" is what I call gambling. and T&B indicators. The *only* reliable option. From what was writtten, I don't consider a spin a safe option anymore, Many modern gliders won't stay in a spin but rather go into a spiral dive rather quick. No option. I noticed the TruTrak spins up in 3 seconds, gives an acurate bank angle even if powered on in a turn, and uses relatively little power. No, TruTrak does *not* give you a bank angle. It gives you a turn rate. Relying on an instrument without fully understandiing it is what I call gambling. Does anyone have an opinion about this instrument I hate it, exactly because it seems to give you a bank angle while it does not. or others that would do the trick? Buy a real old fashioned turn & bank indicator and get some training. Without training, you're lost in IMC even with the best instruments. Or, better yet, fly safe and don't let you get trapped. It's possible. Stefan |

I'm with snoop: prevention is better than the cure.
In any case, it's got to be one of the lowest risks facing glider pilots. I know more people that forgot to hook up the elevator on their ASW 20s than have been sucked into clouds. In 5000 hours of glider flying mostly in the Western USA, I've never come close to being sucked into a cloud, as moving to one side or the other, moving out from under the cloud, opening the dive brakes, or just speeding up have always been sufficient. The only area where I have experienced strong enough lift to be of real concern was flying in the Ely-Tonopah area. So, use the "45 degree rule" when flying in areas with powerful lift, and you'll be fine. Still, knowing how to descend through cloud may be worthwhile. I've never had to do it, but two of our club members have had to do it after while wave flying. It doesn't cost anything to check the benign spiral ability of your glider, or to see GPS or compass methods might work for you. snoop wrote: Best advice?

Lots of good feedback for me. Thanks! I think (as suggested) that I
can stay clear of Cu. What concerns me is wave flying. As I understand it, I could be well clear (upwind) of the clouds by my 2000 ft, and then within seconds, slightly wetter air comes in from upwind and condenses, and suddenly everything goes white...

" Would this instrument then not be useful for keeping the wings level in clouds? I can imagine in uncoordinated flight, like a forward slip, the wings would be banked, but the turnrate would be zero... Matt |

I have a TruTrak, and it is technically true that it measures turning rather than bank angle. However, given that you turn by banking the glider, you would think it would do a good job of measuring bank angle. And, in fact, it does. Matt |

Same here. I am happy with my TruTrak although I never needed to use it and
hope I wouldn't. Just like my parachute. Treat it the same as last resort and you will be safer. If you get one, I recommend before permanently installing it to connect it to a 9v battery and go up in a 2 seater under the hood with an instructor to get the feel of it. You'll find out, as I did, that you can keep the wings level and even level off from a bank using the TruTrak alone. Well worth the $450 IMHO.

Yes, of course you can keep the wings level with the TrueTrak... as long as you remember that it's a turn indicator and not a bank indicator. I just don't like its display. (For a reason, but this is my personal opinion.) You may ask: what's the fuss, as long as I fly coordinated, turn and bank are related, aren't they?. Well, up to 45 degrees, yes. Bank steeper, and the turn rate will diminish again, reaching zero at a (theoretical) bank angle of 90 degrees. Now, bank angles of more than 45 degrees are not that uncommon in gliders, so you must understand this behaviour and keep it in your mind. The interface of the TrueTrak is not very helpful in doing so, as your original post ("TrueTrak gives a bank angle") illustrates. A last note: I've never actually flown with the TrueTrak, so I don't know how fast it responds. As gliders are pretty slippery ships, any turn indicator with less than instant response is useless, so check this. Stefan |
