The facts on the card
The card carries these facts from its Wikipedia article.
- When extended into the airstream, air brakes cause an increase in the drag on the aircraft.
- When not in use, they conform to the local streamlined profile of the aircraft in order to help minimize drag.
- Air brakes differ from spoilers in that air brakes are designed to increase drag while making little change to lift, whereas spoilers reduce the lift-to-drag ratio and require a higher angle of attack to maintain lift, resulting in a higher stall speed.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Air brake article was read about 20,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 53 and blocks with 41: each hit it takes is cut by 16 %.
How to get Air brake
