I don't see how a mis-adjusted altimeter gets by the pre-flight checklist. Instruments: altimeter set to field elevation? Mike Do I detect a bit of "invulnerability" there. ![]() It is easy to not be able to see how it can happen, until it happens to you. Under the right circumstances it can be very easy to do. To the point even a highly trained, F16 Thunderbird pilot can do it i.e. Mountain Home AFB Crash. Brian CFIIG/ASEL |

You check it, see that it's a bit off, and set it so that it's correct. All the while, never noticing that the thousands hand is in the wrong place. The human brain has a powerful capacity for illusion. If you "know" that something is true, it can be difficult to see otherwise. Especially when the object in question is small and you're not concentrating on it. -- Mike Ash Radio Free Earth Broadcasting from our climate-controlled studios deep inside the Moon |

Having the altimeter off by 1000' is would be easy to overlook in a hurried check. Having it off by several hundreds should be caught. I assume that would grounds for failure on a check ride. Mike |

Right, hundreds errors are easy and should always be caught, thousands errors are tougher. When it happened to me, I think the altimeter was reading around 0, with field elevation at 700ft. I turned it the quicker way, ending up with a reading of -300ft, never noticing that the thousands hand was under the zero. I didn't notice at any time during the tow either, even though I was watching it in order to release at 3,700ft. It was only after release, when I could relax and take my time, that I finally noticed that it was reading 1,000ft low. -- Mike Ash Radio Free Earth Broadcasting from our climate-controlled studios deep inside the Moon |

Hi all, My checkride is a long way off, but this evening I read the PTS for Gliders for the first time. *I noticed this section: "Use of Distractions During Practical Tests Numerous studies indicate that many accidents have occurred when the pilot has been distracted during critical phases of flight. To evaluate the applicant’s ability to utilize proper control technique while dividing attention both inside and/or outside the cockpit, the examiner shall cause a realistic distraction during the flight portion of the practical test to evaluate the applicant’s ability to divide attention while maintaining safe flight." Obviously, the Examiner isn't going to do anything dangerous, but what sorts of distractions have people encountered? *It is obvious when the distraction occurs....or is it something subtle? --Michael At the end of my private glider exam when on short final, the examiner asked me to land on the taxiway instead and not to roll beyond a certain point. |

asked me to land on the taxiway instead .... May we assume that you said "no"? Tony |
