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.

A330 NORMAL AND ABNORMAL PROCEDURES - VERSION 2026. The main goal since the initial APP design was to introduce all important elements from the latest versions of (generic AIRBUS A330) FCOM , FCTM , QRH ,MMEL , CDL and Normal checklist. The app enables the user to study absolutely any SOP of the A320 without any manual. With a simple user-friendly interface, it links the essential information needed for the lessons to the appropriate manual reference and further explanations. Lessons follow a didactic and easy methodology, with supporting graphics and real pictures taken in real simulator sessions . This APP must be used only for training purposes. It has not yet been approved for any Aeronautical Authority , but it is updated with the last Airbus information and new changes constantly. Advantages: - It is perfect to prepare screenings and Flight Simulator checks. - It helps instructors explain all normal and abnormal procedures to students. - It is really good for A330 Pilots to remain updated. - Very convenient for cadets to develop understanding on how to find the information in the A330 manuals , as it can be tough at the beginning. Strengths: - It stresses the Golden Rules of AIRBUS [FLY, NAV, COM First] for all abnormal SOPs. The sequence of each failure explanation always follows the AIRBUS Golden rules as a key to battle any failure in a safe, professional and efficient manner. - THE APP is wide knowledge database of 1300 pages that covers from Normal SOPs to the most complicated ABNORMAL SOPs. - It covers all Abnormalities and Emergencies that appear in any simulator check of any airline in the world. The Author is CAPTAIN A320 / A330 / A350 & EASA TRI/TRE and DEVELOPER in the APPLE DEVELOPER PROGRAM. All the new changes introduced in FCOM , QRH , FCTM , NORMAL CHECKLIST will be updated every month automatically.
