wishboneash Posted September 24, 2015 Report Posted September 24, 2015 Brilliant video. Probably doesn't apply in many scenarios for Mooneys (where multi-engines apply) but useful nonetheless to know. Quote
carusoam Posted September 24, 2015 Report Posted September 24, 2015 (edited) I think that is the same presenter as the 'children of the magenta line'. Very interesting to watch. Pretty interesting topic regarding the power of the rudder compared to ailerons with the addition of the change of AOA. Unfortunately, we don't have power steering beyond my rudder trim...? Later in the presentation, the runaway trim is somewhat similar... best regards, -a- Edited September 24, 2015 by carusoam Quote
Mooneymite Posted September 25, 2015 Report Posted September 25, 2015 (edited) This is also the same guy who was instrmental in the copilot's excessive rudder use in the AA Airbus crash. (Vertical stab/rudder failure) I say "instrumental" because there is no way to determine his culpability. The big issue that surfaced was the huge industry mis-understanding about Va. Pilots fly as they are trained! https://m.youtube.com/watch?v=lNWbUB68oO4 Sad. Edited September 25, 2015 by Mooneymite Quote
carusoam Posted September 25, 2015 Report Posted September 25, 2015 (edited) Caution: that video is horrible to see... it opens with... 9/11 footage then goes directly into flaming wreckage in the streets of NYC. MM, I recall the full rudder deflection discussions. By design, full control inputs are expected to be acceptable below Va. Has training improved to include how drastic the speed of those inputs can be? IR training does to some extent, but that is to best control the plane.

Best regards, -a- This is one of a long seres of videos about crashes. The crash investigations are generally fascinating, but yes....there are rather morbid dramatizations of crash scenarios. Thanks for the warning. Quote
carusoam Posted September 25, 2015 Report Posted September 25, 2015 What makes that tough to watch is it looks awfully like the real footage. I'm not going back to look closer... asside from that, I appended a couple more sentences to my first post... best regards, -a- Quote
Mooneymite Posted September 25, 2015 Report Posted September 25, 2015 Well...after this crash video, I welded my rudder in the centered position and don't dare touch the rudder pedals..... Crosswind operations are much simplet now. VBG Quote
carusoam Posted September 25, 2015 Report Posted September 25, 2015 I used to relish full control deflections in my M20C... Including dumping the rudder out during landing maneuvers. Not so much, since I aged a bit and my plane got more expensive. Best regards, -a- Quote
Hector Posted September 25, 2015 Report Posted September 25, 2015 Excellent video. Well worth watching. Thanks. Sent from my iPad using Tapatalk Quote

I had not heard of "cross-over angle of attack" before and how it played a role in certain recovery situations. The last bit about the Delta pilot getting out of a jammed elevator during take off by rolling to reduce was quite something. Who would have thought of that? And then the "drinks are in first class" comment. LOL. 1 Quote

(Vertical stab/rudder failure) The big issue that surfaced was the huge industry mis-understanding about Va. I still disagree with conclusions, I think the industry understood it just find, they just changed the rules to protect airbus. I would have used a titanium alloy skeleton with tongues instead of the fiber composite tongues, but that would have cost more $. 2 Quote
Mooneymite Posted September 25, 2015 Report Posted September 25, 2015 By "industry misunderstanding" was inferred there was a knowledge disconnect between the engineers who built the planes and the pilots who flew them. If the designers need to make changes, okay.....but tell us before we go break stabilizers off! As far as the Boeing hard over rudders, Parker Hannifin swore rudder reversal was impossible with their PCU design. However, there haven't been any more incidents after their perfect design was changed. Quote
