In the input controls management dialog, support was also added for slope and null zone handling as well as axis reversal. In this release, you will find that we have expanded our Input Controls management and handling logic greatly, to allow and include all Airbus input device controls, such as dual side stick input, dual tiller support, spoiler and flap axis input controls, rudder and brakes handling as well as more complete management for the Thrustmaster TCA Airbus series of hardware (A320 side stick, Thrust Quadrant as well as TQ add-on axes, like flaps and spoilers, together with the landing gear lever, auto-brake control and parking brake etc). This is a maintenance update which fixes several issues identified since our last public release and in preparation for our upcoming A320-X and A321-X Sharklets products which are soon to be released. The AC also references SAE standard ARP 4105B Abbreviations, Acronyms, and Terms for Use on the Flight Deck (paywall), and ICAO Doc 8400.I am happy to announce that our latest update (v5.0.1.151) for the A320-X, A319-X and A321-X for P3D v4 and v5 (64-bit) is now live and available through our download page.


This is to prevent confusion when a label appears in multiple locations. Use only one abbreviation and/or one icon for labeling a function. They can be full text (e.g., "Standby"), abbreviated text (e.g., "STBY"), acronyms (e.g., "AGL" for "Above Ground Level"), as well as icons (e.g., for "On/Off").Ĭontrol labels must be visible, legible, and understandable for the population of pilots that will use the controls, per § 2X.1555(a). Labels are the most common means used to identify and describe controls and other devices in the flight deck. $^1$: FAA AC 20-175 - Controls for Flight Deck Systems

That labeling is also typically electroluminescent, so the fewer the letters the cheaper (not just for LO, not just for airliners). It wouldn't make sense to deviate just for the auto brake (its ECAM indication is also LO). Note: Messages on displays are abbreviated to save space, and are in all caps for readability (see: Why do aircraft cockpit displays use uppercase fonts?).
