Code of Conduct

Communication

Times

  • All times will be communicated in a way that is unambiguous. This communication may be a local time, with a UTC offset specified.

    For example:

    0800 UTC+9 on a specific day is a moment in time that is unambiguous. It might be communicated on 26 April 1993 as:

    199304260800+09:00 which indicates the year (1993), followed by the month (04), the day (26), then the local time (0800) and then the timezone in which that time occurs (09:00 9 hours ahead of UTC).

    while:

    0800 is ambiguous, because there are many different moments of 0800 around the world. A reader, independent of their location, is unlikely to be able to determine which time you have communicated.

    Sometimes the UTC reference datum is called Zulu time and is specified with a suffix of the capital letter Z. This too, is acceptable.

    For example:

    0800Z is a moment in time that is unambiguous (date notwithstanding). It is 0800 at zulu time, or UTC. A reader, in any location, is now able to comprehend which time you have communicated.

    Do not say, 0800 Fantasia time. Since, this risks being ambiguous. Does Fantasia run daylight savings adjustments throughout the year? Are they running right now? Are they running on the date of your specified time? This specification of time is at high risk of failure. Use UTC (equivalent GMT) or zulu time, or some other, unambiguous reference datum that your reader is certain to understand, or easily able to come to understand.

    A simple thought experiment is to assume that the reader of your specified time is on the Moon at the time of receipt. They also see your email written on the ground in the moon dust; they have no specific software that will attempt to disambiguate (and often get it wrong!). Now ask, does this person know what time you just specified?

    If not, your time is ambiguous and you need to disambiguate further.

Phrasing

Specific phrasing may be used within the team for efficiency and disambiguity. This phrasing is consistent with AirServices Australia Aeronautical Information Package (AIP) General (GEN) 3.4 (5) RADIOTELEPHONY PROCEDURES. The AIP General can be found here: https://law.1007036.casa/aip/aip/general.pdf Search this document for the string "RADIOTELEPHONY PROCEDURES", which will take you to approximately page 250, and to the following sections:

  • 5.9 Phonetic Alphabet
  • 5.11 Transmission of Numbers
  • 6.1 Standard Words and Phrases

Other sections of the AIP GEN 3.4, such as call signs and readback requirements, are not within scope.

Friday

By order of George Wilson, a public bar must be visited on Fridays, for the duration of all Fridays in all places.

"We'd better go to the pub - it's Friday somewhere!"

Snakes

Someone once said that snake encounters are dangerous. Do not believe this sentence. Believing it will kill you.

To survive a snake encounter, follow these very simple steps, in this order.

  1. Leave the snake alone dick head.

Snakes while flying

If you are flying an aeroplane, particularly during a critical phase, and a snake appears in the cockpit, follow these steps:

  1. Leave the snake alone dick head. If unable e.g. the snake won't leave you alone, then make friends with the snake.
  2. Continue to fly the aeroplane.

Importantly, omit these steps from the after take-off checklist:

  1. Open cockpit door.
  2. Climb onto aircraft wing in an effort to achieve Leave the snake alone dick head.

Disputes

Disputes that have failed to resolve by typical methods of resolution are terminated and ultimately determined by a game of Table Tennis.

Location Reporting

  • IATA codes are for throwing exceptions. Use ICAO.

Please Don't Say Just Hello In Chat

Media

  • The 2008 remake of Get Smart starring Steve Carell does not exist.

Health & Safety

  • Do not eat at the kebab shop. You might die.
  • Do not take the drug Phenylephrine. It is the oil that comes out of snakes.

Maintaining extensions of existence

Don't leave everything you own at the pub, especially your own existence.

Why not just specify ISO 8601 standard to begin with rather than hoping that some particular representation of time is unambiguous?

That only handles times that are communicated in writing.

I'm shit at table tennis, so this is unfair and discriminatory.
Also, i think your slander of the kebab shop is probably false and possibly actionable.
I'd eat there and make you watch.

Not sure I can PR your gist... The URL needs to be updated to https://www.airservicesaustralia.com/aip/current/aip/general_01MAR2018.pdf

I have written a program that removes the date from URL each time the AIP is updated.
