The Comma Crusader

In the high-stakes interconnected 21st century, clear communication is not just important—it's critical. For example, in aviation, a misplaced comma in a maintenance report or flight plan could lead to misunderstandings with potentially serious consequences. At PAI Consulting, we understand the unique challenges of professional writing. Let's explore some essential comma rules that can elevate your documentation.

The Basics: Commas as Pause Indicators

Although commas may not be as misused as apostrophes, people often have trouble with the more complicated ways of using them. You already know about how commas can indicate a slight pause in a sentence, but they also have other uses. Let's dive into some specific examples relevant to aviation writing.

A Series of Things

Generally, when more than two items are listed in a sentence, they are separated with commas.

Example: "The pre-flight inspection covered the fuselage, wings, engines, and landing gear."

Note: This does not apply when the items in the list include internal punctuation; then you would use semicolons to separate each element.

Month, Day, and Year (American English)

When spelling out a full date and the year does not end the sentence, use a comma after both the day and the year.

Example: "December 17, 1903, marked the Wright brothers' first successful flight in a self-propelled aircraft."

Nonrestrictive Clauses

This is the name given to a clause that wouldn't change the meaning of a sentence, or make the sentence's subject confusing, if it were taken out. In other words, it is secondary information to the main point of the sentence. These clauses are set off from the rest of the sentence with commas.

Example: "The Boeing 787 Dreamliner, which features a carbon-fiber composite airframe, has significantly reduced fuel consumption compared to its predecessors."

Nonrestrictive Appositives

If a part of your sentence provides some explanation about the noun, that's an appositive. It's nonrestrictive if taking out the clause won't confuse anyone.

Example: "President Bush signed into law the Aviation and Transportation Security Act, called Public Law 107–71, to create the Transportation Security Administration."

If There Is Only One of the Subject

A person's name is set off with commas if it is related to the sentence's subject; this is also a nonrestrictive appositive.

Example: "Alaska Airlines' first female COO, Constance van Muehlen, took office in 2021."

Note: If the subject can refer to more than one person or thing, you do not use commas around the name. This is because the subject of the sentence would be obscured without this callout. The name becomes essential to understanding who the subject is.
