Horizontal and Vertical Separation

[compressor stall]

Could someone either answer or point me in the right direction for vertical and horizontal separation between..



IFR and IFR class C
IFR and VFR class C
IFR and IFR class D
IFR and VFR class D
IFR and IFR Class A radar
IFR and IFR class A non radar
IFR and IFR class E radar
IFR and IFR class E non radar
Class G - IFR and IFR in time height and distance as to what constitudes mutual traffic.


I have answers to a couple, but would like a more comprehensive list to assist situational awareness, understand odd clearances and clearance restrictions and make requests that would facilitate ML Centre's work.

Cheers :ok:

PS IFR and VFR class E not required!!!!! :}

Separation standards are separation standards and are the same irrespective of the class of airspace you’re flying in. The class of airspace determines what specific service you provide to the different categories of aircraft in that class of airspace.

e.g. Aircraft are separated using the exact same standards in class A , B, C, D or E. However, for example, in A there are no VFR’s allowed . In C, IFR’s are separated from IFR’s and VFR’s, but VFR’s only receive traffic information on other VFR’s. In E, IFR’s are only given traffic information on ‘known’ VFR’s, but are separated from other IFR’s.

Separation standards are quite numerous and complicated, which is why we sometimes make mistakes, however the basics are as follows:

Longitudinal (Distance) separation: 5 miles by radar, or 20 miles by DME/GPS.
There are other variations using RNAV equipment, etc.

Longitudinal (Time) separation: 10 minutes established at the same position.

Vertical separation: 1000ft

Lateral separation: 1 mile between the ‘possible’ position of 2 aircraft. Navigation tolerances and equipment error tolerances are added to the reported positions of the aircraft.

As I said, there are many variations of the above that applies in different circumstances, even in the same piece of airspace, but these are the basics.

Hope that helps.

"Separation standards are separation standards and are the same irrespective of the class of airspace you’re flying in. "

A number of times comming out of E and another A/C wanting to climb into E, "clearance not availavble" to the aircraft requesting climb. That IFR a/c could req a VFR climb, or if we are both in G centre just gives each other as traffic, but does not seperate us.

What gives ?

In class G you get no seperation service. This means the controller is not responsible for your seperation from other aircraft, you are.

This is what changes between classes of airspace, the service you get from the controllers, not the actual seperation standard.

Duf gave 1000' as the vertical standard, the table of cruising levels would seem to indicate that 500' between IFR and VFR is standard. Also the seperation is 2000' and IFR only above FL290

[AerocatS2A]

Yeah true, but the background rule is 2000', RVSM is the (widespread) exception.
