(futurama professor voice:) the huh-whaaa?
what eggzactly is an ultrasonic speed sensor? (hint: no such thing)
pop quiz: what did (does?) the space shuttle use to measure air speed?
pop quiz: what does the F22...the most advanced fighter aircraft flying today...use to measure air speed?
answer: pitot tubes...(plural.)
in a nutshell...a pitot tube is the 'best' (cost-vs-accuracy) speed measuring means available. the one the airbus was using was defective and that was part of the civil lawsuit. i think there was a criminal one, as well
a somewhat related true story: i saw someone drop a 7' or so wide fiberglass cowl (covering) from an S-3 from about two feet height onto one of the pitot tubes. the pitot tube didnt budge and didnt get a scratch (it was fairly strong stainless-steel, i think) yet the cowling completely ripped (it was fiberglass...or some sort of cheesy composite) where it caught on the pitot tube. -

this is why i track the flight path on my own when im on a plane.
youre an idiot.
you dont know jack nor shit about modern avionics...so stfu and go suck the tailpipe of an F14
and. how did you get your GPS to work? every aircraft ive been on since they 'invented' civilian use GPS has jammed mine. -

True. But don't you have to hold your phone to the window? Plus your freaking out would just cause the crew to become stubborn, which would make you more likely do die. THE EXPERTS don't like being upstaged.
Yet how could a PLANE not have a gps speedometer, as well a attitude meter? Even in 2009 my phone had those things.
Right now my WATCH has those things.

you missed the part of cost-vs-accuracy.
untried tech makes for too much expense in production, maintenance, and repair...to say nothing of the ass-bag maintenance crews that are paid exactly fuck-all for how many lives are in their hands.
it they wanted uber-precision theyd use LIDAR...but its entirely too 'spensive, plus it has flaws that are potentially worse than pitot tubes. -

No no no.
More like Airbus and Boeing have engineers who have been there since the 1960s and don't feel like learning this new technology.
If you want accuracy you go after it.
This is why $100 smartphones, which are a far-eastern technology, are way better than ANYTHING we had before at sensing where they are and how high up they are. Cos the Chinese don't care about keeping their engineers employed in a cushy role for 50 years for some research they did in their 20s. -

IDK, it just does. in an B737.
if you sit by the window and just hold your phone to window level, they, the gps will work.
id show you a screen cap but thatd reveal the flightpath and people would know where i was form and where i was going. -

the chinese havent invented shit...ever. they even stole gunpowder and took credit for it.
modern cell phone technology is japanese, western (mostly US...some european), then korean/indian (tie)...altho modern cell phones wouldnt be possible without two juden who stole the technology as der juden do so well, and created a US based corporation. sneaky, sloppy juden...kristallnacht their asses back into the age of egyptian slavery. that never really happened. -

no. i tried everything and short of connecting to the onboard wi-fi i had zero GPS capacity no matter what airport or what aircraft. every single time as soon as taxiing started GPS went out and magically as soon as we stopped, either in the middle of nowhere or 'docked' against one of those flexi-stair-thingys, it came back on. -

i dont freak out form a situation i could have no impact on.
im the kind that just clenches my teeths and fists and stretch my ass when i see the imminent coming and just take it. -

well, i guess they do that in home of the brave and on the land of the free.
here, securities are pretty lax. -

2018-02-11 at 4:41 AM UTCIn an aisle seat I get zero GPS reception. The signal relies more or less on the phone being held up to a window. Yes, holding it a little off a window will work, it doesn't matter. So long as you have line of sight to one or more GPS/Glonass/BeiDuo satellites. Holding it up to a window at 35k+ feet this shouldn't be a problem.
In fact you should be able to get mobile reception at such an altitude no problem. -

i held it up against the window and constantly got told to turn it off by the steward-person, and no, no cell receptions if your over an ocean.
and depending on your device, my phone gps accuracy is always off by tens of thousands of feet when im up there. the altitude and speed is more or less as accurate as the pilots announcements.
