Pilots, it's time to get rid of your sight level, water bottle or whatever "old school" method you have been using to determine cloud height. Introducing Cloud Topper, a revolutionary new sight level designed specifically for the iPad and iPhone. With Cloud Topper you can use your device camera, gyroscope and accelerometer as a traditional sight level. Plus you can enter the distance to a cloud and Cloud Topper will calculate your height above or below that cloud. The displayed cloud height is even corrected for the curvature of the earth. Cloud topper is a fun, easy to use app that should be included in every pilots EFB. Cloud Topper is not an FAA approved source to determine cloud height.
