JANUARY/FEBRUARY 2010 AUSTRALIAN AVIATION
you are going to do, and then you have to
allow in the fullness of time for negotiation,
and that's what we're doing."
McCormick acknowledges that there
have been mixed responses from the indus-
try to the changes. "I had a chief flying in-
structor write to me and say, ' ank you for
limiting the number in the circuit because
I was turning base the other day and there
were seven aeroplanes between me and the
threshold. All I was teaching the kid I was
with was collision avoidance, not how to fly
"You get the other side too who say,
'We're going to write to you, we're seriously
concerned about safety and issues at the
approach points,' and I get a letter and the
first five points are economic."
While the changes have had an eco-
nomic impact, the operators Australian
Aviation spoke to expressed more concern
about the unsafe environment which was
created by the sudden implementation of
the new procedures, and the lag in distrib-
uting new training materials and informa-
tion to pilots.
"Within the first three or four days of it
happening, one of our aircraft was coming
into the entry point and there was another
coming straight towards it from a person
who had been told to turn back, and they
took it literally and turned 180 degrees,"
As such, he and others see that the
GAAP changes have merely moved the
risk of a mid-air collision from within the
circuit to the entry points when an aircraft
is refused entry into the circuit, although
this is now much better since the earlier in-
cident. " ere's been discussion on how to
handle that and at least the operators have
reached a decision on that, but that could
have been fatal," said Hoffman.
While he admits that RACWA is pri-
marily concerned about the risk to pilots of
a collision at the entry point, there is also a
greater risk at entry points such as Six South
at Jandakot, which are over built up areas.
At Moorabbin that is evidently less
of a problem. "We are not getting the
feared problem of aircraft being refused an
entry at an inbound reporting point," one
experienced Moorabbin instructor said.
"At Moorabbin they will have us overfly to
the other circuit or else have us fly to join
upwind overhead the runway, thus allowing
for one of the six circuit aircraft to drop out
between the inbound aircraft calling at the
inbound point and getting to overhead."
McCormick has conceded that the addi-
tion of the cap on aircraft in the circuit has
had an economic impact. Hoffman notes
that while the impact of this was lower
as the changes were implemented during
winter, the impact was tangible.
"I'd look outside my window and there
would be eight or 10 aircraft sitting in the
holding area, and we would get stories of
people waiting 45 minutes for a gap. at
was obviously huge," he said.
As a result of the cap, some operators have
had to change their operations. "We are start-
ing earlier and finishing later and staggering
the start times. We're a third of the activity
on this airfield, so if we stagger our start
times, that helps everybody," said Hoffman.
"We'll find solutions, but only because
we see them as interim," he added.
Longer term, keeping a cap arrangement
could have some detrimental effects on
the booming international flying train-
ing market, which has been the lifeblood
of Australia's general aviation industry.
Accordingly, operators could be forced to
make major changes.
One possibility flagged by RACWA could
be moving most of its operations away from
Jandakot. "We own our own airfield at Mur-
rayfield (approximately 40km south of Perth)
and we're giving some serious thought to
transferring some of our activity down there."
However, CASA has left the door open
for an increase in the cap. "We will look to
move the cap because as I've said all along,
it was there as a temporary measure," said
Caught in the middle of the debate has
been Airser vices, which has seen its role at
the various airports increase as part of the
interim GAAP changes. In that respect,
Hoffman is full of praise for the action that
the ATC provider has taken at Jandakot.
"Airser vices have been fantastic through
this as they were given directives, and they
have implemented them.
" ey've worked within the confines of
what they were given. But of late Airs-
