Airspace Boundaries
 

Let's say you are flying through Avalon airspace at 2500ft. Those familiar with the aerodrome would know the AV CTR is class D from the surface to 2500ft. From 2500ft to 4500ft you are in Class E airspace. If you intend to fly at 2500 ft in the AV area as a VFR aircraft will you be in class D or E airspace.

Check AIP ENR 1.4 Para 1.1.7. If cruising at the boundary of two vertically joining airspace areas, you must comply with the requirements of the less restrictive class of airspace (Class E is less restrictive than Class D). I can't remember the specifics though but the Class E around AV is a bit different than normal Class E in that you need to call the the tower even if you're transitting VFR. :ugh: Been bitten on the ass by that one before!

A025 is class D

Just checked with my compadres and they confirm A025 is Class E

It's always the less restrictive of the airspaces. I thought this would have been pretty common taught knowledge.

edit : And no, you don't need to contact anyone, just monitor the frequency and squawk. They made it pretty clear when AV Approach came into place. Probably to not clog up the 135.7 controller with pretty ordinary transiting calls.

Oh dear, the things you read on here.

2,500 to 4,500 ft is class E over Avalon.

You do not need to call the tower to transit class E over Avalon because it is not their airspace, however you must fly in accordance wih standard procedures for class E airspace, eg radio, transponder etc.

If you do call Avalon tower they will tell you to call someone else who cares.

If you have any concerns, why not fly at 2501' - the answer is very clear then.... if you are scared of E, fly at 2499' :ouch:

What is the tolerance applied to altimeters ... that may be your get out of jail card if you are 225'd

The whole 2,501 ft thing is plain crap.

It's 2500 to 4500 ft Class E !

Class D below it, is surface to 2,500 ft.

Period.

And he wonders why people want check flights?

The Avalon procedures are listed here for both tower and non-tower times

To clarify, this is NOT correct!

As a Class D ATC you would be surprised how often I get asked that question!

Nothing in Ontrack about Avalon that I can find...

It's under the Moorrabbin entry. :rolleyes:

That's clever.

Ofcourse it is, when you want Melbourne you look up Sydney dont you??:E

In their defence they are essentially right next to each other in terms of airspace.

What, another link and another two web pages? Is that too hard or made by a non-pilot? Flying's difficult enough as it is without this.

025-045 is E, but it is a piece of airspace I always give an advisory on centre. It is a busier piece of airspace than you might think, and surely for the 5 seconds it takes to give the controller the heads up it can save you and them some stress...

It's a nav test.
