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. Cloud Topper is not intended to replace weather radar or pilot skills and judgement. Always consult the Aircraft Manufacturer’s Aircraft Flight Manuals, Federal Aviation Administration (FAA) websites and publications, and individual company policies.
- Added color change option for cloud height text. Press the cloud height number to change the color.
- Optimized for iOS 10.
Ratings and Reviews
I deleted it immediately, and wish I could get my money back. Two big problems:
1) once the app is opened and you grant camera access, you can’t swipe up and kill it or switch apps. I had to force reboot my phone to get back to the app switcher.
2) it requires you to know the distance to the cloud you’re measuring “using RADAR”. Like I have that?!
Not very accurate. A small error in angle is a quite large when looking at a cloud which is miles away. This app consistently indicates I will fly into a cloud when in reality I clear it by seventy hundred feet.
Developer Response ,
Thank you for your review. At larger distances it’s more accurate to use the angle vs cloud height. A very small change in angle will change cloud height considerably. This is true for a physical sight level or even a laser levels that are used for precise measurements. Cloud Topper is a great tool for a quick estimation and cloud height will be more accurate the closer you are to the cloud.
Great addition to any flight bag!
Does just what is says and then some! Been looking for an app like this for quite some time and its finally here! Thanks for the great addition to the App Store.
With Family Sharing set up, up to six family members can use this app.
