It makes sense if you know what camelCase is (
could be middle letter only caps or could be leading letter caps).
From Wiki:
Camel case is the practice of writing phrases such that each word or abbreviation in the middle of the phrase begins with a capital letter, with no intervening spaces or punctuation. Common examples include "
iPhone" and "
eBay". It is also sometimes used in online usernames such as "johnSmith", and to make multi-word domain names more legible, for example in advertisements.
From Google:
camel case
[ˈkaməl kās]
NOUN
camelCase (noun)
- a typographical convention in which an initial capital is used for the first letter of a word forming the second element of a closed compound, e.g.PayPal, iPhone, MasterCard.
So in essence the FAA system isn't able to accept
JOHN SMITH but is "expecting"
John Smith (
most likely).
