Howdy,

So I am flipping through the pages of this month's Flying magazine and reading about Gulfstream's new G150 which was having its first flight.

I see that during the flight test process that this plane has what I think is a long pitot tube, painted red and white, extending from the nose. I have noticed this on many new aircraft as they start their certification trials.

Am I correct that it's a pitot tube, and if so, what exactly is its purpose. By this I mean why don't they just use the normal pitot tubes?

Thanks.

Greg

there is less interference with the long pitot tubes and therefore give more accurate information.

Correct. The stock pitot tubes are taking air that is disturbed to some degree by airflow over the fuselage. By rigging a pitot tube that is in totally undisturbed air, the engineers can determine any error, and apply a correction to the stock pitot/static system.
