Vocabulary: Avoiding Collisions

Flashcards on this page

This page includes a 14-card interactive flashcard deck. Here’s a taste:

• TCAS — Traffic Collision Avoidance System — onboard equipment that detects nearby aircraft and warns the crew of a possible collision.
• resolution advisory (RA) — A TCAS command to climb or descend to avoid a collision. It must be followed immediately — even against an ATC instruction.
• traffic advisory (TA) — A TCAS alert warning of nearby traffic — one step below a resolution advisory. The crew prepare but do not manoeuvre yet.

Members study all 14 cards — flip, shuffle and star them, and review each one with spaced repetition on the Study dashboard, timed for just before it fades.
