I don't have an IPhone. That's pretty cool. I'd go that route then.

No need to buy a separate GPS reciever.

so here's the 1 million dollar question: why?

Homeslice · 01-07-2009, 01:13 PM

Cuz I'm just a data freak. I think it'd be cool to check the altitude wherever I am, even riding up an elevator or biking up a mountain.

That's another question, how often do they re-calculate the altitude? Hopefully it's not just a once every 60 seconds kind of deal.

An IFR approved gps is dead nuts accurate. Any over the counter handheld unit and/or cell phone gps device is not anywhere near as accurate as an IFR certified gps receiver in altitude.

btw - my plane has 3 gps units in it and none of them are as accurate as the old steam gauge altimeter in the panel. Why? None of them are approach certified.

just wanted to make sure you weren't the one flying the next shuttle mission or anything

A lot of new smartphones have built in gps receivers, so I am sure there could be options for getting altimeters on a lot of them.

iphone and the blackberry storm are two that do have gps receivers, I will check my storm to see if the garmin program provides an altimeter or if my weatherbug program does.

The blackberry storm will report elevation in an app called Blackstar. Apparently there is a bug that inverses the number, but it is still giving you an accrurate number, just with a - sign on the front.

so before I board a plane again I'll make sure to ask the pilot if he/she is aware of that

Hmm, this looks cool....
