Furthermore, I think ADR switching could have contributed to the confusion (this is my speculation). At one point the PNF had switched the AIR DATA switch to 'F/O on 3'. Later on after the captain is in the cockpit, they switched the AIR DATA to 'Capt on 3'. So now they were presented with ADR 3 information on the PNF side, which agreed with the ISIS, and ADR 2 info on the PF side. As I've seen before with ADR switching, the information does not immediately get shown but rather 'scrolls' to the indicated value. I could be wrong but this is what I've noticed with normal working ADRs, when using the ADR switch on the 320 family.<br /><br />The cockpit conversation would explain the confusion then, when upon switching the ADR to 'Capt on 3', the pilots note the descent in PFD1 and the ISIS, however see the altimeter on PFD2 (from ADR2) scrolling UP to an erroneous (frozen?) original altitude of 35,000, despite the fact they are descending at 10,000fpm. Furthermore, the PF had indicated he had lost V/S indications on his PFD, which further hindered the situation.<br /><br />Again, all we can do is speculate, but the F/O Static Port being blocked (however unlikely), seems to fit very well with the actions of the PF and the later cockpit conversation about 'you're climbing there, but there you're descending'.peeFactornoreply@blogger.comtag:blogger.com,1999:blog-36913768.post-24329657786514488662011-06-08T15:54:24.106-07:002011-06-08T15:54:24.106-07:00You only feel *acceleration* not *velocity*.

His inner ear was just one more "instrument reading" at odds with all the others. Pilots are actually taught not to trust their inner ear too much, since you can actually flip your plane completely over on a dark cloudy night if you try to fly by feel alone.C.

Unfortunately, it probably wouldn't be within the 15% margin of an airliner.<br /><br />The computer could directly compare GPS acceleration to pitot acceleration. The autopilot could command slight acceleration & decelerations to test the instruments, but by then, you've just made air travel uneconomical.<br /><br />Makes you wonder if this space travel business is commercially feasible, since the margins required to make air travel economical are barely real.heroineworshipperhttps://www.blogger.com/profile/08441970270714146188noreply@blogger.comtag:blogger.com,1999:blog-36913768.post-27934561141933114852011-06-01T21:21:50.988-07:002011-06-01T21:21:50.988-07:00The pilot is supposed to recognize this.

There must be some other MAJOR factors here. If the tubes froze at cruise it should be something a pilot could recognize or some other system would identify. Are we really saying that if both tubes freeze at the same time the end result is death? Doesn't make sense. Maybe the indicators can't handle that case? Maybe the pilot can't?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36913768.post-55633627244422739932011-05-31T22:47:43.731-07:002011-05-31T22:47:43.731-07:00I too find it sad that even in this day and age, t...I too find it sad that even in this day and age, there are no backup ways to sense airspeed / altitude on a major airplane - like GPS. I'm not advocating wiring the autopilot fully over to a GPS, but I seem to recall this being not the first deadly incident caused by the Pitots (ex. taped over on AeroPeru 603?), and I fail to see how a backup GPS reading would anything but help in such cases, even if not normally used as a main instrument (but as a check).<br /><br />In fact, the biggest problem I see with the tubes is no indication of failure if it happens. Perhaps - being such important instruments - they could be a bit better diagnosed (in-flight): I could imagine a simple setup that periodically tries to reverse the pressure in the tubes ("blow" in them), to verify they are not clogged up (and possibly even de-clog them along the way); I have no idea whether that was ever actually done though...Maxnoreply@blogger.comtag:blogger.com,1999:blog-36913768.post-6089471327601745932011-05-31T21:16:59.770-07:002011-05-31T21:16:59.770-07:00Thank PAUL BREED

Every warning light is screaming at you and yet you cannot work out why...<br /><br />A thought that I have had about the information provided by pitot tubes is are the engines functioning? The engines can provide information about air pressure due to the power that they are generating. You would need some sort of force measurement device examining the moving propeller or fan assembly in relation to the airframe. As the propulsion system generates power, how much power it is generating is then capable of being measured by the force it is exerting to the airframe.<br /><br />Pitot tubes just seem unreliable on their own. If one of them freezes up, a substitute will, and so a separate route to determining air pressure is important.Andrew Mooneyhttp://AndrewM60@excite.comnoreply@blogger.comtag:blogger.com,1999:blog-36913768.post-67038576085634432722011-05-31T16:40:22.630-07:002011-05-31T16:40:22.630-07:00Paul,
