...revise the definition of “Night”

An update to the FAR was posted recently and was effective October 12th. One of the changes that caught my eye was a revision to the definition of "Night". I thought to myself how could it be that somehow Night has changed. Perhaps the FAA was going to simplify the various night rules. So I read on with curiosity only to find out that the FAA was merely making a correction in the title of the source for obtaining the published twilight time. Specifically they removed the word "American" from the source document.

SUMMARY: The FAA is correcting the title of the publication ``American Air Almanac'' to its current title ``Air Almanac''.
  Background
The former ``American Air Almanac'' was created to meet the general requirements for air navigation in the United Kingdom, the United States, and Canada. In 14 CFR 1.1 the definition of night refers to twilight times as published in the ``American Air Almanac''. The ``American Air Almanac'' publication ceased in 1953 and is currently called the ``Air Almanac''. This technical amendment corrects the title of the publication.

The "Air Almanac" can be found here

  1. Well, they got the change in just under the wire... 60 years must be their time limit for making this kind of update.
