  • hey. its you off air crash investigation :')

  • Excellent analysis of how automation does remove us from the very basics of how we fly aircraft using first principles which have been there since day one.We have very limited opportunity or desire to revert to these basic skills on line flying which quite evidently become apparently consuming when presented with multiple failures of automation.We need to recognise it is just as easy to switch that button off than leave it on and lead us into analysis overload.

  • @chinapilot He's a former Royal Air Force pilot and flying instructor so first of all get your facts right. Secondly your comment displays a dangerous attitude whereby you directly correlate a person's skills to their general level of experience.

  • Excellent David, keep fighting on our behalf ... and NEVER give in!

  • What's so difficult about basic P+P=P (Pitch + Power = Performance) when all else fails? This concept was proven to successfully effect a recovery in a simulator.

  • @Iamfukenripped i went slightly off topic there, but yeah.. the fact that peoples lives are at stake and the reality of what M Learmount is saying comes through in every sense, is very un-nerving .. and we can only hope that they listen and fix this problem.. and soon.

  • I have never liked the ideas of so many computers going into an aircraft and especially how the throttles work on modern aircraft, which from what i heard is all electronic now too (ECM??) the over use of comuters in general is depriving humans from mental and physical skill ... I dont think this good and it scares me to think that our children in the future are going to be cabages... almost like that movie The time machine .. where in the future everyones dunced.

  • Out of many many articles on the subject, M Learmount is making a lot of sense. thank you, sir !

  • The AF 447 pilots simply did not recognize the stalled condition. If they would have looked at (and believed) their standby instruments the situation could have been salvaged. The pitch attitude of the 330 was nearly 15 degrees nose up for most of the final 3 minutes of flight. The pilots simply forgot the most basic of all rules - pitch + power = performance. Automation has made today's aircraft safer than ever. The result is a modern airline pilot has become a systems manager / monitor.
