Code of Conduct

Technical

Never use Scala. Not even then.

If you see someone using Scala, take educational measures, not punitive. Help them be better.

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.

  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. It is 0800 at zulu time, or UTC.

  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 COMMUNICATION SERVICES. The AIP General can be found here: https://www.airservicesaustralia.com/aip/current/aip/general.pdf Search this document for the string "4.9Phonetic Alphabet", which will take you to approximately page 271, and to the following sections:

• 4.9 Phonetic Alphabet
• 4.11 Transmission of Numbers
• 4.12 Transmission of Time
• 4.13 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!"

Disputes

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

Health & Safety

Do not eat at the kebab shop. You might die.
