Airspeed Reduction

Asked by: 1684 views
Airspace, FAA Regulations

Scenario: ATC says  "Citation 123, cross ABC VOR at 230 knots". Citation 123 for example is cruising at 280 knots.  At what point does ATC expect the pilot to slow to 230 knots? I ask because if there is traffic behind the Citation and to not to create a loss of proper ATC separation.   Thank you for the feedback.

    In time to be at 230 KT by the time it reaches ABC VOR, just like the instruction says. It’s really not more complicated than that. The controller is concerned with separation at ABC and after.

    Of course the point at which the pilot =begins= to slow down is going to vary with the aircraft. A dirty airplane flying at 250 KT will take less time to slow down (without scaring the passengers) than a clean airplane flying at 300 KT. One descending may take more time to slow down than one already level. ATC just wants separation; it’s up to the pilot to fly the airplane.

    I had a friend who got a DUI who was a pilot at one of the big ainrlies. He did have to alert the FAA and they proceeded to do an assessment of his problem. If the assessment turns out bad, they will require treatment. If it seems like an isolated event, probably not. The first time is not usually fatal to a pilot career, but repeat DUIs will probably end a pilot’s career.
