Definition
In ATC communications, plain English refers to using ordinary, clearly worded language — rather than standard phraseology — to convey a message when no prescribed phraseology exists, or when standard phraseology is insufficient to make the situation fully understood. It is intended to be concise, unambiguous, and immediately understandable to both pilot and controller.
Plain English
If the standard radio words don't fit the situation, just say what you mean in normal, clear language so the other person understands you straight away.
Context Anchor
Used in radio communication with air traffic control, especially when a situation does not fit a standard call or when clarification is needed.
Derivation
Plain comes from an old word meaning clear or easily seen. English is the language being used. Together, plain English means clear, direct English rather than coded, overly formal, or confusing wording.
Why Pilots Care
Ensures critical information is understood without delay or confusion during non-routine events.
Intuition Check
Do not assume plain English means casual chatter or ignoring standard radio procedures. It means clear, normal wording used only when standard aviation wording does not fit or does not make the message clear.
Example Sentence 1
Unable to find a standard phrase for the situation, the pilot reported in plain English that a passenger was unwell and requested priority handling.
Example Sentence 2
The pilot used plain English to explain the mechanical issue instead of relying only on standard reports.
