At the risk of sounding defensive and getting Andrew all fired up again (the reason so many avoid RAS to start with), I think it is pretty obvious that I made several mistakes throughout the course of this flight that caused the end result. I would say, given the conditions and clearing trend at takeoff and climb, that to say the entire flight was just an indicator of a dumb mistake of a careless pilot is a bit of an over-generalization and Monday morning quarterbacking at its worst.
While I have zero time under the hood, i have no doubt that an ARHS would have significantly changed my plan for the flight, but given the conditions under the clouds (the LS-4 that was forced to land in the valley just after me due to incredibly low ceilings) i don't know that it would have resulted in any better of an outcome, and probably would have given me a false sense of security and forced a more dangerous decision when the best option was to indeed bail out. How many pilots would intentionally go into IFR when there is a VFR hole still available? The greatest mistake in this flight was the hurry up mentality and decision to try and dive through the VFR hole. I have no doubt in my mind that the outcome of my flight was pilot error at 18,000 feet, and little confidence that I would have used an artificial horizon to my benefit and not to my demise if i had had one on board. |

Sitting aloft may (would!) have been genuinely worrisome as it clouded up beneath you, but clearance agl is clearance agl; it's difficult to have too much of it when the ground beneath you is vanishing, especially in something as "IMC benign" as a large-deflection-landing-flap-equipped glider... - - - - - - I have no doubt in my mind that the outcome of my flight was pilot error at 18,000 feet, and little confidence that I would have used an artificial horizon to my benefit and not to my demise if i had had one on board. Well-said, IMO. Your "second guessing" seems spot-on from where I sit. Some of the peanut gallery's thoughts expressed previously in this thread remind me of the old saw about the difference between being *interested* in something vs. being *committed* to something, you know, the one about the hen having an interest in a ham and eggs breakfast, and the pig being committed. The peanut gallery is interested; Joe PIC is committed. Bob W. |

You're right, Chris. I did misinterpret what you said. Thanks for
clarifying. On another note, having the 90 deg flaps improves your chances greatly against total loss of control but provides no help against coming out of the clouds too low to recover (or not coming out at all).

Agreed, i absolutely love 90 degree trailing flaps on the HP. I have tried the benign spiral in several ships, and the '14 was the only one that i would actually trust to stay slow and stable in rougher air. It does work in other gliders, but it needs to usually be set up properly, and assumes no large turbulence.
I had already descended 2k feet or so completely hands-off and when i bailed out, and the glider was completely stable, exited the cloud upright, and continued flying away from me...couldn't ask for better performance in a dire situation. Chris |

Must be surreal watching your glider flying away from you...
From the condition of the glider it looks like it made relatively low energy landing. Who landed first? Ramy |

From the condition of the glider it looks like it made relatively low energy landing. Most of the terrain near Mount Washington is below treeline, and 99.99% of it is very densely spaced trees. (Chris landed between two trees spaced 4 feet apart.) My glider has a profoundly stable benign spiral and a Jar-22 'safety cockpit' (more modern gliders have even stronger cockpits). I wear an emergency parachute. I've never made a parachute jump. I'm old enough to have weak leg bones, but I've never had a fracture and I'm not overweight. Breaking a leg on a parachute jump is a non-zero possibility. If I were in Chris's situation, my first thought would be to stay in the glider until it came to rest in the trees. I'd deploy my PLB while I was waiting to descend (hoping to get a rescue call out before I lost satellite contact in the dense trees), make a Mayday radio call, and tighten my shoulder straps. I might have a few seconds to pull back the stick, slow down and stall into the trees. I'd rather have the limited protection of the glider around me, rather than plunge through the tree canopy dangling from a parachute. I know that you're not suppose to activate a PLB until you've exhausted self-rescue options, but crashing a glider into the trees, I'd expect to need rescue. Being off trail in October in the White Mountains late in the day is a precarious survival situation due to hypothermia, especially if injured and relatively old. Chris's plane flipped upside down after landing. Does anyone carry 50' of spectra cord in a chest pack (to use as a rappel line attached to the parachute harness and anchored to a shoulder strap)? Am I an idiot? BTW, following last year's Reno IMC bailout discussion (RAS discussion can change behavior), this year I limited myself to blue sky dry wave days (had two great wave flights with low probability of IMC), but getting stuck in IMC is still a remote possibility. The year before last I dove through a Foehn hole or two (which is exactly how Chris got stuck). |

Hi Chris
Thanks for surviving, and many more thanks for sharing your experiences with us. Your reports will form the basis of our future decision making while wave flying as well as providing a valuable information for teaching wave flying skills to new pilots. On 05/11/2015 03:16, Christopher Giacomo wrote: While I have zero time under the hood, i have no doubt that an ARHS would have significantly changed my plan for the flight I believe that your primary mistake was failing to establish the hight of the cloud base above the terrain before making the decision to descend. You had the suitable tools available - the Oudie flight computer and VHF radio. After that, bailing out, or crashing with the glider, were the only other probable outcomes. With a "glider cloud flying" rating and a gyro instrument, one would expect to be able to thermal into the base of a cumulus cloud, climb and then exit out the side (hopefully on course to the next turnpoint}. This rating implies that you have the opportunity to practice thermaling into clouds on a regular basis to keep current. There are not many glider pilots who can claim that on social media. With a gyro instrument but no current "glider cloud flying" rating the best one can hope for is to descend to cloud base without pulling the wings off. Your glider's speed limiting drag flaps rendered the gyro instrument redundant. |
