What model is the helicopter?

What is its call sign?

Can I hear the helicopter on the radio?

Yes. Between 1700-0700 (UTC+10), Archerfield Tower closes and all Archerfield traffic operates under Common Traffic Advisory Frequency (CTAF) rules. You will hear Polair42 make its CTAF calls on 118.1MHz, which is on the VHF band. You can purchase a VHF receiver, which will work when you have line-of-sight with the helicopter or you can listen to 118.1MHz online (see below).

These radio calls are made when leaving Archerfield (YBAF) or when inbound to Archerfield from one of the VFR points (IAW ENR 1.1-42):

• Goodna http://osm.org/go/ueDPwz7R--?m=

• Park Ridge Water Tower http://osm.org/go/ueDjS62?m=

• Target, Springwood http://osm.org/go/ueDtTq7Q-?m=

• Mount Coot-tha (TV Towers) http://osm.org/go/ueD0XBNh-?m=

You will also find these points on a Brisbane/Gold Coast Visual Terminal Chart (VTC).

Radio calls are also made on 118.1MHz when Polair42 is keeping separation with other VFR traffic in the area.

Can I hear the helicopter's radio calls without a VHF radio receiver?

Yes. You can listen to 118.1MHz on liveatc.net.

Is the helicopter allowed to fly without lights?

Aircraft generally must comply with Civil Aviation Regulations 1988 -- 195. Polair42 flies under Night Visual Flying Rules (NVFR), like others, but also has an exemption for not displaying lights because it is also flying under Night Vision Imaging System rules.

Sometimes Polair42 displays lights at night regardless.

Night vision imaging system ratings and endorsements are covered under Civil Aviation Safety Regulation 1998 Part 61.P.1 (61.995 to 61.1035). Here are the interesting regulations:

• Limitations on exercise of privileges of night vision imaging system ratings--recent experience
• Limitations on exercise of privileges of night vision imaging system ratings--night vision imaging system proficiency check
• Requirements for grant of night vision imaging system ratings
• Kinds of night vision imaging system endorsement
• Requirements for grant of night vision imaging system endorsements

Can I see the helicopter on a map when it is flying?

Polair42 is equipped with a Mode S ADS-B transponder. This means it can be seen on websites such as http://flightradar24.com/ or can be detected with a home-built ADS-B receiver such as stratux.

However, quite often Polair42 will turn the transponder off and some websites voluntarily block Polair42.

This map does not, and will never, block the police helicopter http://receiver.1090mhz.tmorris.net/ However, Polair42 is not always within range of its receiver.
