Gyronimo Performance Pad -Cessna 172 S- The ultimate flight computer for Mass & Balance and Performance. Calculate and interpolate performance data using the actual values from the Cessna 172 S Pilot's Operating Handbook. (Note - this app does not provide updated POH data. For flight planning, always use the original POH of the airplane you will be flying) Performance Results are updated immediately and displayed in high-resolution graphics, enhanced for the iPad Retina displays. Change all important values using sliders. Experiment with the results and create "what if" scenarios in no time. Find your optimal cruise altitude, takeoff ground roll, landing distance, climb data and stall speeds. The Performance Pad C172S has seven main pages: 1. The Mass & Balance (or Weight & Balance) Page Calculates Center of Gravity, Moments, Takeoff and Zero Fuel Mass as well as Percent MAC (% MAC). Set person and baggage weights in seconds using the convenient sliders. Check if the CG is within limits using three graphical displays - Moment Envelope - CG envelope - Aircraft axis or see a complete load manifest that you can send to your email address to quickly prove that you have completed the Weight & Balance for your flight. 2. The Takeoff Page Using the actual data from the C172S Operating Handbook the Performance Pad calculates and displays Ground Roll and Landing Distance based on: - Aircraft Mass - Takeoff Elevation in MSL (Pressure Altitude and Density Altitude will be computed) - Outside Air Temperature (OAT) - Altimeter Setting - Runway Conditions (i.e. paved dry to grass or extra factors up to 100%) - Wind Conditions Wind Components Computer - Use the Wind Components page to determine your headwind or tailwind component. Rotate the wind dial to set wind direction, set windspeed and the results will be transferred to your takeoff computations automatically! 3. The Climb page Calculates time, fuel and distance based on - Difference between Takeoff Elevation and intended Flight Level - Altimeter Setting - Outside Air Temperature (OAT) - Altimeter Setting - Headwind or Tailwind Component The Rate of Climb and Climb Speed will be displayed. 4. The Cruise Page Using the actual data from the Pilot's Operating Handbook you can determine the optimal cruise altitude based on - Trip Distance - Flight Level - Engine RPM - Temperature - Wind and Altimeter Setting and calculate Break Horse Power (% BHP), Fuel Flow and True Airspeed The Max Range and Range including Reserve will be displayed graphically. The Fuel Management allows to input Reserve Time for Contingency, Alternate and Final Reserve. The Fuel Usage is displayed graphically. 5. Landing Page Calculates Ground Roll and Landing Distance based on wind, elevation, altimeter setting etc. Use the Wind Components Computer to quickly determine head- or tailwind components 6. Stall Speed Page. Calculates The Stall Speed based on Bank Angle and Flap Settings. Stall Speed will be computed as KIAS and KCAS using the actual values from the Cessna POH. 7. Setup - Load and Save up to five Aircraft Settings and Scenarios. - Send a Mass & Balance Summary to your email address. - Visit our video channel and watch tutorials and video manuals. Disclaimer: The Gyronimo Performance Pad is a student, professional pilot, ​and flight instructor assistance tool for plausibility checks and flight training only. All graphics and data provided in this application are used as examples. For flight planning the ORIGINAL Pilot’s Operating Handbook must be used! Performance values can vary significantly with aircraft or environmental conditions and also with your pilot skills. Always consider safety margins for you and the aircraft you are flying.

E6BX is an essential app for pilots of all experience levels, offering a wide range of aviation tools designed to help you get comfortable with the reports and calculations required to fly safely. Included in this app are a visual E6B Calculator, interactive Weather Reports with METAR and TAF decoders, a NavLog Calculator, and many other tools to assist you with aviation calculations. E6B Calculator This is the world’s most popular E6B aviation calculator, already used online by hundreds of thousands of pilots. The calculations are visually illustrated to aid in understanding, showing wind speed and direction, wind correction angle, course, heading, ground speed, and true air speed. E6B is also known as CR, CRP-5 or in German, as the Dreieckrechner. E6B Simulator E6B Simulator offers a manual E6B with step by step instructions and highlights. This brings the same functionality on the website to the app. Weather Reports Search for any airport using the Weather Reports tool, and find the relevant METAR and TAF reports, taken live from aviationweather.gov. Need help understanding METAR or TAF? Tap on any segment to instantly see what it means, or tap the Decode button to reveal the entire report at once. Weather Reports can also display airport data for US airports, including runway directions and lengths, heliports, radio frequencies, and charts. NavLog Calculator Use the NavLog Calculator for either VFR or IFR flight planning. Enter numbers into the table to perform instant calculations. You can add as many lines as you need, and the table can be easily cleared with a single button. Holding Pattern Calculator The Holding Pattern Calculator uses a detailed and informative graphic to help you determine your entry into a holding pattern, and then to maintain that pattern with wind corrections. Simply enter a few basic values to see them instantly reflected in the graphic, then follow the detailed entry and hold instructions. Metar and Taf Decoder With E6BX Metar Decoder, almost everything in any given Metar or Taf is decodable, including elevation, wind direction and speed, wind components, pressure altitude, density altitude, air pressure, dew point, and all sorts of weather conditions. Snowtam & Motne Decoder Paste any Snowtam or Motne report into this tool to decode it. Almost everything in any given Snowtam or Motne is decodable, including type, depth, location, and extent of contamination. Aviation Unit Converter This tool includes all units commonly used in aviation. When you enter a value, it will instantly be converted to all other units of the same type. Convert units of time, distance, speed, pressure, temperature, volume, weight, and mass. Our GPS Coordinate Converter can convert between Decimal Degrees (DD), Degrees Decimal Minutes (DDM), and Degrees Minutes Seconds (DMS). Aviation Unit Converters include: Time Converter Temperature Converter Fuel-Weight Converter Reciprocal-Heading Converter VOR Radial-Bearing Converter Distance Converter Speed Converter Pressure Converter Area Converter Weight Converter Volume Converter GPS Coordinate Converter Additional Tools: Visual Wind Components Calculator Pressure Altitude Calculator Density Altitude Calculator Cloud Base Altitude Calculator Aviation Unit Converter Mach Speed/Speed of Sound Calculator True Air Speed Calculator Indicated Air Speed Calculator Airport Data NavLog Calculator Airport Lists by Country/State Weight and Balance Calculator METAR Decoder TAF Decoder SNOWTAM Decoder MOTNE Decoder Holding Pattern Calculator
