C172N Performance Pad

This app calculates crucial flight performance data for the Cessna 172N aircraft. It assists pilots with mass and balance, takeoff and landing distances, climb performance, and optimal cruise settings using data from the Pilot's Operating Handbook.

Highlights
  • Mass & Balance calculations
  • Takeoff and Landing distance computation
  • Climb performance analysis
  • Optimal cruise altitude determination
  • Wind component calculation
  • Weight & Balance load manifest export

Gyronimo Performance Pad -Cessna 172N- The ultimate computer for Mass & Balance and Performance. - New Version with options for Long Range Tanks and Increased Gross Weight from 2300lbs to 2550lbs. Note: Performance values are computed for 172N standard version with 160hp. Compatibility: requires iPad 2 or newer, or iPad Mini Calculate and interpolate performance data using the actual values from the Cessna 172N 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 2/3 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 C172N 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 you flight. 2. The Takeoff Page Using the actual data from the C172N 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 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 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 and calculate Break Horse Power (% BHP), Fuel Flow and True Airspeed The Max Range and Range including Reserve will be displayed graphically. 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.

In this practice it is possible to carry out the synthesis of cyclohexanone, starting from cyclohexanol and a sulfochromic mixture (chromic acid and sulfuric acid). The simulator recreates a chemistry laboratory with a three-mouth balloon, a condenser, a crystallizer with water, a Tollens test, a Fehling test, a Schiff test, and a Brady test, among other instruments and supplies necessary to perform the synthesis.

Verdict

The call

The clearest difference is price: CloudLabs Ketone Synthesis at Free against C172N Performance Pad's $13.99. CloudLabs Ketone Synthesis also leads on device support (3 vs 1) and iOS requirement (9.0 vs 18.6). C172N Performance Pad's advantage is update cadence (every 14 months vs every 28 months). On ads and in-app purchases there is nothing between them.
