The RLM-Flight app is the ultimate aviation computer. Designed with a clear beautiful interface and easy to use through direct menu selection with all variables at sight converting it in the most powerful, versatile and useful aviation computer you may have in your iOS device. The RLM-Flight has a extensive Menu System: >Altitude & Cloud Base Worksheets: Calculate Pressure Altitude, Density Altitude, Barometric Pressure or Outside Temperature with or without humidity. Also calculates the Cloud Base above ground and Clouds Temperature knowing the Outside Temperature and Dew Point. >Standard Atmosphere: Calculate the Altitude, Temperature or Pressure and the Air Density and Speed of Sound in the International Standard Atmosphere (ISA). > Airspeed Calculations: Calculate the True Air Speed, Calibrated Air Speed, Outside Temperature, Mach number, Total Air Temperature or Pressure Altitude. >Ground Speed & Fuel Rate: Calculate the Ground Speed, Distance, Duration or Fuel consumption. >Glide & Climb/Descent: Calculate Horizontal Distance, Glide Ratio, Descent or Climb Altitude, Angle and Ratio. >Wind Components: Calculate Cross Wind, Head Wind, Run Way, Wind Speed or Wind Direction. >Wind Correction: Calculates the Ground Speed, True Course, True Air Speed, True Heading, Wind Speed or Wind Direction and the Wind Correction Angle. >Compass Heading: Calculate True Heading, Magnetic Heading, Compass Heading, Variation or Deviation. >Holding Pattern & From-To: Calculate the type of entry necessary and the inbound heading to enter in a holding pattern given by the airplane Heading, the Holding Radial and the standard turn (left or right). Also, convert the course from a location into the course to the same location. >Rhumb Line: Calculate the True Course, Rhumb Line Distance and the Great Circle Distance for flight paths specified by latitude and longitude. >Flight Plan: Calculate the Total Distance, Estimated Time in Route, Estimated Time of Arrival and Fuel Burned in a cross country flight composed of an arbitrary number of legs. >Weight & Balance: Calculates the total weight and the resulting center of gravity of an airplane base on the loads arms, weights and/or moments of different items including the empty aircraft weight and center of gravity, pilots, passengers, fuel and cargo areas. >Weight Shift & %MAC: Calculate the change in Center of Gravity, change in Weight, change in Arm or total Weight given the others. Also calculate the %MAC, Center of Gravity, Mean Aerodynamic Chord or Leading Edge of MAC given the others. >Units Conversion: powerful and completely customizable physical units conversion calculations. >Currency Conversion: to calculate currency exchanges between two selected world currencies and common crypto currencies with manual or on-line rates. > Math Functions: to apply scientific functions to the displayed number including angles conversion, trigonometric functions, logarithmic function, decimal hour to hour:minute:seconds, etc. System requirements: iOS 15.0 or above. 30 days Free-Trial.
