Description
It is vital to comply with weight and balance limits established for helicopters. Operating above the maximum weight limitation compromises the structural integrity of the helicopter and adversely affects performance. Balance, both laterally and longitudinally, is also critical because on some fully loaded helicopters, center of gravity deviations as small as three inches can dramatically change a helicopter's handling characteristics. Taking off in a helicopter that is not within the weight and balance limitations is extremely unsafe.
Use this app as an easy tool to verify your own calculations. You can quickly add and remove optional items such as Doors or Dual-Controls. It is also a handy tool to explain the calculations to students.
Currently supported:
• R22 Beta II, with Aux Tank installed • R44 Raven • R44 Raven II • R66 Turbine

This compares nicely to the spreadsheet going around everyone uses in some form or another. It does a CG/loading calculation and shows you graphically whether you are in or out of allowable limits. I use an R44 Raven II with bladder tanks so the fuel calculation is a little bit off. I would be willing to support a "Pro" version, especially if the following could be addressed: - it supported multiple aircraft, so you can select a/c you've pre-entered via a dropdown, and then it would populate the fields - it properly calculated the aux fuel tank amt or allowed entering it - when hitting the three-dot menu button it says "select aircraft" and you MUST select one. The back button doesn't work. Thank you! I know it's free, which must mean it's a labor of love. I find it helpful. Like I said if you want to throw in another hour and make it more perfect-er I'm happy to support it :)

We fly an R22 without an aux tank. This app doesn't work for it. Otherwise, this app is great

Could not change the preset moment. So it wouldn't be the correct CG on the R22 I fly.
