The sectionals are complemented by terminal area charts (TACs) at 1:250,000 scale for the areas around major U.S. airports, and World Aeronautical Charts (WACs) at a scale of 1:1,000,000 for pilots of slower aircraft and aircraft at high altitude. Beginning February 2021, the charts are updated on a 56-day publication cycle.
Aeronautical chart. An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative ...
A World Aeronautical Chart ( WAC) was a type of aeronautical chart used for navigation by pilots of moderate speed aircraft and aircraft at high altitudes in the United States. They are at a scale of 1:1,000,000 (about 1 inch = 13.7 nautical miles or 16 statute miles). WACs were discontinued by the Federal Aviation Administration (FAA) in 2015.
1:72 scale. 1:72 scale is a scale used for scale models, most commonly model aircraft, where one inch on the model equals six feet (which is seventy-two inches) in real life. The scale is popular for aircraft because sizes ranging from small fighters to large bombers are all reasonably manageable and displayable.
Brannock Device. The Brannock Device is a measuring instrument invented by Charles F. Brannock for measuring a person's shoe size. Brannock spent two years developing a simple means of measuring the length, width, and arch length of the human foot. He eventually improved on the wooden RITZ Stick, the industry standard of the day, [ 2] patenting ...
This is the scale which MOROP has defined for O scale, because it is half the size of the 1:22.5 Scale G-gauge model railways made by German manufacturers. [citation needed] 1:43.5: 7.02 mm: Model railways (0) Exact O scale of 7 mm = 1 foot. 1:43: 7.088 mm: Die-cast cars: Still the most popular scale for die-cast cars worldwide, metric or ...
For example, 1:48 scale is 1/4" to 1-foot (or 1" to 4 feet) and 1:72 is 1" to 6 feet, while in metric scales such as 1:100th, 1 centimeter equals 1 meter. 1:72 scale was introduced with Skybirds wood and metal model aircraft kits in 1932 and were followed closely by Frog, which used the same scale from 1936 with their "Frog Penguin" brand. 1:72 ...
