Cairns Control Tower No.3
Increasing tourist traffic, including more direct international services, compelled the introduction of radar to the far north of Queensland. The new Tower was part of the radar implementation plan for Cairns, which commenced in 1992. Previously a procedural Approach service out to 30NM was provided from the old Tower, but with the introduction of a radar unit, using AUSCATS equipment until 1998, the Cairns area of responsibility was extended to 200NM from Cairns. Prior to AUSCATS, the nearest radar was a short-range RAAF equipment used by Townsville Approach.
Retired Air Traffic Controller Geoff Goodall remembers: "Training of controllers on radar commenced 10/89 with a projected transition of mid-1990. Numerous technical problems with the RASPP radar sensors at Hann Tableland (ENR) and Redden Creek (TMA) delayed that to 1992. My 6 month temporary transfer from Perth for the training phase extended accordingly!
"A million stories our radars were the cause celebre for the local feral environmentalists who stopped roads being cut through scrub to the radar sites. Once the radar began turning it had a few nasty features, like invisible Qantas B767s for several months, and also F-28 VH-FKD. No primary, no SSR .. fun times and many worried Frenchmen scuttling around the place.
Tower design was excellent, with a very large cab. When the TAAATS equipment was installed in 1998 the console got Eurocat screens in Coord (Centre) and ADC (right). Eurocat Strip printer and CATIS were at the SMC (far left) position.
"Cairns is a fascinating place ATC wise with first solo circuits mixing it with the B747s and Approach flogging the numerous reef scenic flights to get in front of RPTs. Name another place in Australia where the Flow includes the scenic Tiger Moths in the sequence! (We used to leave it to the Tower to slip the Tigers in, but it went bad too often!). You cant extend traffic on downwind leg for the main RWY 33 on left or right circuit due to mountains filling the windscreen, forcing the buggers to turn base just when you didnt want them to.
"Another interesting fact is that jets in the circuit area for RWY 33 are lost from radar due terrain shielding so radar separation for sequencing becomes interesting. Ditto the floatplane Beavers and choppers out of the Pier (2 miles from RWY threshold) were below radar coverage.
"Ill stop here because Im beginning to drift off, back to the days of instructing airline jets to 'track west of the Coolwaters Caravan park on downwind, and follow the Tiger Moth turning final' ... and them doing it without a murmur!"
