DA42 NG vs Helipilot Question Database
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
DA42 NG
This app calculates mass, balance, and performance data for the Diamond DA42NG aircraft using actual Pilot's Operating Handbook data. It helps pilots plan flights quickly by determining optimal cruise altitudes, takeoff and landing distances, and climb rates.
- Mass & Balance calculations
- Takeoff and Landing performance
- Climb performance
- Cruise performance
- Fuel management
- Interactive sliders for 'what if' scenarios
- High-resolution graphics

Gyronimo Performance Pad -Diamond DA42 New Generation- The ultimate computer for Mass & Balance and Performance. Compatibility: [Diamond DA 42, max GW 1900kg RFM as of 2009, Austro E4B engine, 123.5 kW at 2300 RPM) Note: (The max GW can be set to 1999kg as an option, however, this option is for weight & balance only. Performance data is computed up to 1900kg only) Calculate and interpolate performance data using the actual values from the Diamond DA42NG 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, and climb rate. The Performance Pad Diamond DA42NG has seven main pages: 1. The Mass & Balance (or Weight & Balance) Page Calculates Center of Gravity, Moments, Takeoff and Zero Fuel Mass. 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. - Send a Mass & Balance Summary to your email address. 2. The Takeoff Page Using the actual data from the 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. The Fuel Management allows to enter Reserve Time for Contingency, Alternate and Final Reserve. The Fuel Usage is displayed graphically. Fuel Efficiency is computed in Miles per Gallon and Liter per 100km to set set results in a perspective. 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. Load / Save. - Load and Save up to five Aircraft Settings and Scenarios. 7. Setup - Visit our video channel and watch tutorials and video manuals.

Your best pocket-buddy while you prepare for your written helicopter exam. The Helicopter Pilot Question Database includes 3 000 questions and almost as many explanations, including rich images of instruments, systems, performance charts and more! The app will give you all the necessary knowledge to pass your PPL, LAPL or NLH examination. The Helipilot QDB can also be used to prepare for written VFR helicopter CPL and ATPL exams. This app, and others like it, are developed by a team of experienced pilots and aviation teachers. The apps have been loved by flight instructors and private pilot students since 2013. We are happy to finally be able to offer our English helicopter question database! The app covers the entire EASA Learning Objectives stipulated in EASA Part-FCL (Flight Crew Licensing) regulation and is specifically suited for PPL(H), LAPL(H) and the new license National Light Helicopter (NLH). The app is developed for use in all European states and will therefore show equal success in preparing for exams in all EASA states. The database also works very well to prepare for exams outside the EU region as it thoroughly covers universal helicopter theory.

Verdict
The clearest difference is review sentiment: Helipilot Question Database at 100% against DA42 NG's 50%. Helipilot Question Database also leads on price (Free vs $19.99) and update cadence (every 3 months vs every 9 months). DA42 NG's advantage is in-app purchases (none vs 3) and iOS requirement (15.6 vs 18.6). On ads and device support there is nothing between them.
