I have never heard of this before, does XJ and other regionals still use this eq? And is there any onboard usage, or is it strictly for data compiling for the NASA folks?

Only XJ Saabs have it (as far as I know). The only way we use it is to automatically report OOOI times. There's a tiny green LED on the FO's side that blinks when it's transmitting the times. If it's inop, you make more money. ;)

Tamdar is still in use at XJ. The only thing it is good for (for us at least) is to report the Out off on in times.

TAMDAR has/is in the process of being installed on CHQ 145's. It's a little blue light that irritates the hell out of you and reports your OOOI times without telling you what it actually sent. There's something about weather in there too. I don't think too many guys on the CHQ cert. are too thrilled about it being installed here.

I think we had TAMDAR or something similar on our Seminole's when I was at UND. From my understanding, they gathered weather data for NASA, NOAA or our meteorology department. No one I talked to really knew a whole lot about it. Just one day a few of our airplanes had extra antennas on em. Any other Flying Sioux know any more about it?

Yeah, we've got TAMDAR on most, not all though I think, of our Seminole's. We have no way of controlling it, it just sorta sits there in the nose and does its own thing. It looks sorta like an extra pitot tube.

It measures temperature, relative humidity, pressure, and icing. It can calculate pressure altitude, IAS, TAS, turbulence, and wind direction and speed. On climbout it takes measurements every 6 seconds, in cruise every 3 minutes, and in descent every minute. The data is uploaded in near real time to a satellite that's funded by NASA and run by AirDat.

I guess they use the information to make more accurate forecasts.

so when you former und guys apply to chq or xj make sure you put that you have TAMDAR experience on your resume

ive only seen one airplane that had it activated for chq 260sk one of the continental birds. all of the ones i have seen on the delta planes are deactivated. Im sure there is a way to make it say what we want as far as out and in times. You can always send paper work out the window and have the FA leave the door closed till after the gate checked bags are brought to the door.

Bingo, and by closing up and dropping the break asap.

Flew one of the Delta 135s that had it activated. The captain I flew with called dispatch and asked him about it, and the dispatcher said he didn't know anything about it.
