Test aircraft probe?

[ICT_SLB]

Don't forget the Nose Boom

A lot of test aircraft also have a seperate Nose Boom which carries a Pitot head well ahead of the aircraft plus an OAT probe and two pairs of sideslip & angle of attack vanes. You can see them on both the CRJ-1000 prototype and our CRJ-100 test aircraft on here http://www.pprune.org/flight-testing...en-flight.html

Jimmy,
Beleive we've used both 80 & 100 foot for the trailing cone - best (most stable) length for a particular aircraft seems to vary a bit so we have an internal capstan with appropriate markings on the tubing & the FTE just runs it out as required before the testing starts.
