Military GCA and VFR/IFR

Question. I pretty much think I know what the rules are on this from reading the 7110.65, 7210.3, and AIM.

We have a GCA Arrival Pattern that vectors IFR/VFR aircraft for PAR/ASR approachs into Class D control tower airfiled. This a "pattern" delegated to us by the Approach Control that serves us. This Arrival Pattern exists in Class 'E' airspace.

Most of the time aircraft come in to do multiple PAR's or ASR's. Thier climbout is RWY heading to 2500 (IFR/VFR).

My understanding is Unless a LOA exists for VFR aircraft to recieve seperation services (even if they are being vectored) there is NO seperation (500 & 1 1/2) requirements between these VFR and other VFR/IFR aircraft working in the pattern except for Wake Turbulance Seperation (Ch 5-5-4)...

The only other seperation requirement is between IFR and other IFR a/c.

Is this research/thinking correct?

Thanks for the input/help.

I agree. I worked at two DOD airfields that ran approaches to class D towers from class E airspace. No separation minima between VFR/IFR except wake turbulence.

There is phraseology for that... something like "vfr practice approach approved, no seperation services provided"

The "no separation services provided" is for uncontrolled airports when an a/c is doing a vfr practice approach(I.E. does not apply to class D airport)

A GCA approach is an instrument approach therefore IFR separation must be provided between aircraft on final. However between an aircraft on final(or any IFR a/c) and a VFR aircraft not on final you only provide 500 ft and "green between".

4-8-11 Practice Approaches

Or "traffic..so and so..good luck" As we used to say in the Air Force VFR stands for Very Fuc*ing Risky

I completely disagree with the later half of your remarks. there is NO seperation requirement I found out in class D or class E airspace EVER except wake tubulance separation for VFR to VFR or VFR to IFR a/c UNLESS an LOA exists (as per 7210.3).

If an aircraft, regardless if VFR or IFR, is cleared for an instrument approach it is to be afforded IFR seperation.

OK, where are you getting this info?

As a matter of fact, there is no where that this info is stated you are wrong. Only requirement is Wake Turbulance unless it is operations are in a TRSA.

PARs and ASRs are NOT instrument approaches. Therefore, there are no separation minimums per .65. At our base, we had a LOCAL reg that required 3 miles sep for VFR/IFR to the same runway and 6 miles for opposite direction.

However. I'm fairly certain VFR is not guaranteed separation services when conducting instrument approaches thanks to "no separation services provided." But I'll have to grab my .65 to verify it
