Capn Bloggs - it would work like any other controlled airspace, let's say a D Tower like Albury, but without the "cleared for take-off" bit. There are always many variables so I will only explain one:
A is on ground, has advised taxiing and requested IFR clearance. ATC acknowledge with "will advise".
B is in the air and is requesting clearance for whatever instrument approach.
Controller then makes an assessment of the relative positions and times and does one of the following:
- B is to hold at 4000 - A is cleared to 3000 but on an outbound track that will, after a few minutes, provide lateral separation (This is very easy if there is surveillance), or
- B has already been cleared for the instrument approach so no clearance is available for A until [time calculated by ATC]
- A can wait of depart VFR, weather permitting, with traffic advisories from ATC, or wait;
ATC then manages the two aircraft in turn through the IFR approaches.
It is very easy for a competent controller and requires far less R/T than traffic information. The pilots can also concentrate on flying instaed of trying to separate themselves.
If the trainee pilots are destined for jobs overseas than we will also be training them for what happens in advanced aviation countries.
