Checked 09AUG17

Vertical buffers between aircraft inside and outside airspace

Answer 10

Vertical buffer with base of CTA - VFR aircraft

Vertical buffer with base of CTA - IFR aircraft
Except on pilot request, assign levels to IFR aircraft to provide a buffer with the base of CTA in accordance with the following table:

1) Base of CTR VFR Level (eg 1500ft)
vertical buffer of 500ft from base of CTA
EXCEPTION for IFR traffic operating less than 500ft below the CTA base - provide 1000ft from base of CTA

do not assign the same level to aircraft under procedural control,

cleared to the same holding fix or holding fixes that are not laterally separated,

while they are flying within 10 minutes of the holding fix.
