The Bankstown and Moorabbin accidents might suggest, that probably the most
needed, are the "turning final" and "short final" calls.

Hi all,
If its only recommended, why would you make more than one call? Its
mandatory to recommend making these calls, not make them, isnt it?
With transmissions every 30 sec as described there is bound to be lots of
2
at once calls that no-one understands.(2 stations transmitting at
once).Then
again 20% of calls are unintelligable now!
I will continue making downwind calls only myself, until more calls are
mandatory mandatory.

I recently had the pleasure of listening to the controllers
at Kennedy Centre, La Guardia Approach and LGA Tower calls on
a night after 65kts winds had closed all the NY crosswind
runways and stacked up aircraft across America. The
controllers managed a course correction call of 3-4 seconds
duration, with a read-back of similar length, followed
immediately by another call, etc. This resulted in about 7 -
8 instructions with read-back every minute.
If an average circuit is say 2 minutes from the joining call
to turning final call there is time to make 32 NY style calls
(without a read-back) and we have only to make 3 per circuit,
we should have little difficulty landing 3 - 4 gliders almost
simultaneously and all making their required 3 circuit calls
plus inbound calls.
"NY style calls" does assume glider pilots will use the
stated minimum call contents and not discuss separation matters.

We will be briefing the pilots at the upcoming Easter comp to
be sensitive about their radio calls on the finish frequency
and into the circuit.
I would suggest that if we have more than a few gliders in
the circuit making the 'mandatory recommended' calls, a few
more calling 10km inbound and trying to find one another
(FLARM helps enormously here btw from experiences at Lk
Keepit) and a busy airfield surface (so that in circuit
gliders need to sort out who is landing where) the frequency
will become in danger of congestion resulting in a reduction
of safety.
We obviously cannot (nor should we) tell pilots NOT to make
the 'mandatory recommended' calls, but pilots do need to
ensure there is enough space for new, incoming gliders and
for critical messages important to safety. With 50 gliders
ariving over 30 minutes, frequency congestion is possible if
everyone is not sensitive to the overall picture.
It's good airmanship really.
