Gyronimo Performance Pad Piper PA-28RT-201 -Arrow IV- The ultimate computer for Mass & Balance and Performance. Compatibility: requires iPad 2 or newer, or iPad Mini Retina Calculate and interpolate performance data using the actual values from the Arrow IV Pilot's Operating Handbook (POH). Finish your complete fight planning in just a few seconds. Performance planning has never been easier and quicker. Results are updated immediately and displayed in high resolution graphics, enhanced for the iPad 2, iPad Retina and iPad Mini. 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 Arrow IV 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). 2. The Takeoff Page Using the actual data from the C172G "Rocket" 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 long grass or snow) - Runway Slope - Wind Conditions 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 Also 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 5. Landing Page Calculates Ground Roll and Landing Distance based on wind, elevation, altimeter setting etc. Like on the Takeoff Page you can 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. Mode Switch: The Performance Pad can be used in two Modes: "Individual Mode" All calculations can be done independently from each other. "Plan Mode" Calculated values will be forwarded to the next page and an additional "Flight Summary Page" is available. Choose this mode if you want to do a complete performance planning.

The Global Express Flow and Emergency Trainer app is an interactive tool for BD700 pilots to learn the cockpit and different Memory items and flows. The user can use this app for initial training and recurrent trainings. Use in conjunction with the AFM, QRH or your company checklist. Note: this is not a simulator, not all button functions are exactly as in the aircraft, this is a tool to practice flows and memory items and to be familiar with the cockpit. You can create your own flows so you can easily practice your company specific flows. We recommend using the Global Express with any ipad but it is also fully functional with the iphone. After you have created a flow, there are two modes “Practice” and “Test”. In “Practice” the user will learn the different flows by following a step by step instruction. In “Test” the user will have to complete the flows without any guidance. This app is not for operational use, The author will not take responsibility for any errors and/or situations caused by the use of this application. This app has no connection with the manufacturer of this airplane or model. All rights reserved
