Which link do you wish to identify as the Link that had the most effect in failing to prevent this accident? |

Land and Live! 100% Dick! Whatever the consequence of landing never out ways dying. Get on the ground and worry about the rest later. |
Flying a complex type like it was a rented scooter.
So many weak links in this chain.
A total failure to protect the passengers. One button... One button is all he had to push.. If only he knew the button was there.. |
Which one button is it you think would have saved the day?

If the mishap the pilot had more recency of experience in instrument flying, and perhaps a better internalized Inadvertent IFR procedures - in other words, had he been able to draw on the full suite of flying skills that a pilot with an instrument rating would be expected to have - then which button was or was not pushed to aid their flying efforts isn't the primary thing to address. Those buttons are there to help you fly. |
With the poor levels of airmanship, decision making and professionalism displayed in that accident, no button in the world was going to save him from himself.

I don't think that this is a healthy attitude to take, that pushing a button is what solves your immediate flying problems.

Wings level Vbroc 700fpm RoC |

i don't think he had Autoland fitted........................:)
The SPZ7600 has a G/A feature that levels the wings, initiates a 700fpm climb at Vbroc It requires knowing you're in deep **** ... but had he engaged it,, he'd have popped out into gin clear skies in less than 30 sec |
Not talking about Autoland Many aircraft have the G/A feature but you need to have the AP set up correctly to allow for upper mode engagement - we have discussed his lack of awareness of how dangerous his situation was and there were many occasions when he didn't even need the AP to save him, just turning round or slowing down would have done that. |

Also the NTSB gave scant attention to exactly what was the Company SOP's re use of the installed Autopilot, did not delve into the details of what was taught about using the Autopilot during Training, and there was zero mention of what the Accident Pilot did during his flights in the S-76 re use of the Autopilot.
By investigate fully....I mean going deeper than just a cursory examination of the practices. Being a VFR Only Operation.....I can see some Cheese Holes appearing that would not happen had it been an IFR Operation. As the S-76 was being used more like an upscale JetRanger I can imagine all that Gucci Kit was not being used to its maximum benefit. 212Man echoes my earlier posts when I espoused always flying with the Force Trim ON....and using ATT Mode at all times. The weather conditions and height above ground the aircraft was flying in.....and the FAR's, and Part 135 OpSpecs for the Operator may have influenced the use or non-use of the Autopilot in a Hands Off Level. General limitations are usually no use of an Autopilot below 500 Feet AGL unless on an approved Instrument Approach where both lateral and vertical guidance is being received. |

The Go Around button

I hope the go-around button only works in approach mode as accidental engagement in cruise in the weather would be most unpleasant Nothing unpleasant if you were to hit it in the cruise, it just commands a 750 ft ROC and maintains the current heading. |

To be pedantic, this aircraft had the SPZ-7000, but the point is valid. However, I'd put money on it was being flown in SAS mode with the trim off, so G/A wouldn't have helped. Just relooked at the NTSB report and I'm surprised there is not more mention of what state the AFCS selector panel was in - should have been possible from bulb filament analysis.
He had the entire SPZ 7000 suite to help him out.. but, as you mentioned,, it was being flown like a jet-box |

For the GA mode to work you need to be already coupled, selection of GA cancels all other modes but after engagement any lateral mode may be used, if any pitch mode (VS, ALT, ILS, IAS) is then selected GA is cancelled. would work if the button were pressed in the cruise, but difficult to see, given the position of the buttons, how you could do this accidentally.

As said, you would have to be coupled to the autopilot for this to possibly work and he certainly was not or this wouldn't have happened. I hope the go-around button only works in approach mode as accidental engagement in cruise in the weather would be most unpleasant. There really would be zero reasons to hit the go-around button if coupled.
I can't imagine any reason he'd be in SAS only mode...but it's possible. |

There are those - not me BTW - who don't like or trust autopilots, usually because they were trained on basic (or old) helicopters and were never taught to use them or never bothered to learn.
It wouldn't be a surprise that he was flying completely manually if he was one of those. |
