Just wanted to clarify somthing about RVSM..
Ok soo according to the Instrument Jepp book, the definition of RVSM is any airspace between FL290 - FL410, where airplanes are seperated by 1,000 feet vertically.
My question is what is the vertical seperation minimums between FL180 - FL290, or even victor airways 1,200 - FL180 or is there any at all below FL290 and if so how does ATC determine the seperation altitude between odd and even headings? I cannot find the answer anywhere.
This is all I found in the AIM which doesnt really answer my question unless I overlooked it :
4-4-11. IFR Separation Standards
a. ATC effects separation of aircraft vertically by assigning different altitudes; longitudinally by providing an interval expressed in time or distance between aircraft on the same, converging, or crossing courses, and laterally by assigning different flight paths.
b. Separation will be provided between all aircraft operating on IFR flight plans except during that part of the flight (outside Class B airspace or a TRSA) being conducted on a VFR-on-top/VFR conditions clearance. Under these conditions, ATC may issue traffic advisories, but it is the sole responsibility of the pilot to be vigilant so as to see and avoid other aircraft.
c. When radar is employed in the separation of aircraft at the same altitude, a minimum of 3 miles separation is provided between aircraft operating within 40 miles of the radar antenna site, and 5 miles between aircraft operating beyond 40 miles from the antenna site. These minima may be increased or decreased in certain specific situations.
NOTE-
Certain separation standards are increased in the terminal environment when CENRAP is being utilized.
Anyone know what the seperation is if any
