Some variations that came to mind (not limited to those):

  • ecs
  • environmental-control-system / -systems
  • climate-control
  • cabin-temperature
  • something else (including renaming/merging/synonymizing existing tags)

* may not cover planes with just cabin heat, and its usage guidance says "Air conditioning system and/or cabin pressurization", but it's unclear from the tag alone (ACS is possibly not a commonly used aviation acronym)

Along with your recommendation, explain why please.

Example questions that need such a tag:


1 Answer 1


I would propose using the header names of the ATA chapters. The relevant one here would be ATA 21, Air Conditioning.

The wiki lists the chapters and sub-chapters as:


  • 00 Air Conditioning - General
  • 10 Compression
  • 20 Distribution
  • 30 Pressurization Control
  • 40 Heating
  • 50 Cooling
  • 60 Temperature Control
  • 70 Moisture/Air Contaminant Control

indicating that all climate systems functionality such as pressurisation, heating/cooling and cabin air compression all fall under the header of Air Conditioning.

An event like sudden cabin pressure loss due to a cracked fuselage is not [aircraft-systems] related and would not fall under the Air Conditioning tag, so a [cabin-pressure] tag would be useful.

    $\begingroup$ It sounds counterintuitive, doesn't it. A question on sudden pressure loss due to a cracked fuselage would not fall under Air Conditioning, so no I would not suggest synonymising the two tags. The sub-chapter list was purely to illustrate that all climate systems functionality falls under Air Conditioning according to official terminology. $\endgroup$
