R66 Weight & Balance graphs the center of gravity and weight with current fuel and at zero fuel. Want to know whether or not your heavy passenger *really* has to sit in the back and how much fuel must be maintained to stay in CG? This app will tell you at a much lower cost.
This app will be a great help to new R66 pilots that need to quickly figure out if they have to put their 250lb. friend in back and the 160lb. teenager in front to maintain CG as well as how much fuel must be maintained to stay in CG in cases where it’s out of CG at zero fuel. It’s also a great educational tool for new pilots to quickly see how much influence a seemingly insignificant amount of weight has on CG. You’ll quickly find out why R66 pilots are most desirable in the 150 - 200lb. range. You’ll also discover why the R66 CG envelopes are beveled at the corners.
The primary data displays are Longitudinal and Lateral graphs. You can look at the raw numbers if you want to, but it’s designed to give you CG data in graphical form. You’ll find yourself hardly ever looking at the raw number display.
It is intended to be run on iPhone 5 and larger up through an iPad Pro. On an iPhone 4s, the graph will be compressed (good excuse to trade up).
• Shows CG for both zero fuel and current fuel.
• Contains experimental support for auxiliary fuel tank that Robinson is working on.
• If out of CG at zero fuel, it shows the minimum fuel that must be maintained to stay in balance.
• Longitudinal and Lateral CG graphs.
• Holds multiple R66 helicopters for those who fly more than one and can easily switch between them.
• Accommodates the R66 Turbine and R66 Turbine Marine, though there isn’t any difference in the CG envelopes yet.
• Individual weight entries for all seats and baggage compartments
• Accommodates doors on & off; makes more difference than you would think.
• Shows overweight warnings for the overall helicopter and combined seat & baggage.
• Runs on iPhone 4s through iPad Pro.
• Light weight app: uses little space and low CPU usage.
