Mike Tickner
rang up to see how we were going and told me that a cold front had
just passed through Bankstown, heading our way, with 30+ kt winds
on the ground. I tried to get clearance to transit through CTA into
Bankstown but got the well known response, "Clearance is not
available, remain OCTA".
I'd hoped that
at the lower levels we would get some relief from the headwind component,
but at 6000 feet our GS was 124, and as we descended into the Bankstown
lane of entry the GS dropped to 99.
Through the
lane I was grateful for my co-pilot. He navigated with the VTC as
I flew the plane insome of the worst turbulence I have experienced
in years, with wind gusts producing variations of 25 kts IAS. In
the Satatoga, Vma is 134 KIAS at MAUW and scales down to 105 KIAS
at minimum weight. I estimated Vma for our current weight at 120
KIAS and focussed on maintaining speed below that. I stayed as high
as possible in the lane in the hopes of encountering the least turbulence
and advised SY Radar that we were having difficulty maintaining
altitude and to expect occasional incursions into CTA. Finally,
to the relief of all, we landed at Bankstown. The flight time had
been 3 hours 14 minutes.
Mike met us
there, realised a fast turnaround was out of the question and looked
after us all until Kay and Phoebe were ready for the leg to Melbourne.
They knew it was going to be another, even longer, bumpy flight.
Mike gave Phoebe a set of wings to wear - she had earned them.
After Mike's departure, Garth and I set off back to Brisbane. As
we lifted off at Bankstown, the tower controller advised an approaching
aircraft the crosswind had just gusted to 28 kts. It certainly felt
like it.
On climb-out
BN Centre called us up and advised of Sigmet 02 (mountain waves
and severe turbulence up to 15,000 ft). No messing around now -
I requested a clearance at FL 160 and out came the oxygen masks.
The flight back was smooth until the descent into Archerfield. At
about 7 PM I gave Mike a call to see how the flight to Melbourne
had gone. He was still in flight, battling his way home to Sydney
through the turbulence. He told me they had had to stop on the way
and the decision at Melbourne had been to stop overnight and continue
to Hobart the next day. I bet Kay and Phoebe were glad to relax.
Through it
all, Phoebe managed to give us a smile, even though at times she
must have been feeling dreadful. I really appreciate that I could
play a part in this very worthwhile mission.
