The calculations for this App were developed with the Limitation Section 2, Performance Sections 5 & Wight and Balance Section 6 of the Manuals R66 RTR 661 R00015LA, R44 II RTR 462 H11NM, R44 Cadet RTR 463 H11NM, R44 RTR 461 H11NM & R22 RTR 061 H10WE. Multiple tests have given minimum negligible variations, always remember that results may contain variations.

The App Calculates with Heater On and Off for appropiate:
-Weight and Balance for every model.
-Density Altitude
-Limit of Manifold for every R44 and every R22.
-Limitf of Manifold For Max Takeoff Power for every R44 and R22 Beta and Beta II.
-VNE or NES for every model.
-Hover Ceiling IGE for every model.
-Hover Ceiling OGE for every model.
-Rate of Climb Performance, 2700 Lb Gross Weight for R66.
-Rate of Climb Performance, 2200 Lb Gross Weight for R66.
-Power Assurance Check MGT for R66.
-Crosswind/Headwind Component.
-Flight Plan Calculates of Estimates:
Endurance, Trip Time, Trip Fuel, Landing Wieght.
