C400 TTX 1.6

The Gyronimo Performance Pad for Cessna 400 and TTX models offers an advanced tool for comprehensive performance analysis and weight & balance calculations. Designed for aircraft equipped with the Continental TSIO-550-C engine producing 310 HP at 2600 RPM, this software introduces functionalities such as Lean-Of-Peak computations and an optional TKS-Fluid calculation feature.

The application's professional load manifest feature allows for digital signing via iPad, with options to email or print using AirPrint. The software facilitates accurate interpolation of performance data directly from the Pilot’s Operating Handbook (POH), enabling pilots to complete flight planning swiftly and efficiently. Results are immediately reflected on high-resolution, graphics-enhanced displays optimized for iPad 2/3 and iPad Mini devices.

Adjustable sliders allow users to modify key parameters in real-time, supporting "what-if" scenario analysis to determine optimal cruise altitudes, takeoff ground roll, landing distances, climb performance, and stall speeds. The Performance Pad consists of seven primary pages:

1. Mass & Balance Page – Calculates Center of Gravity, Moments, Takeoff, and Zero Fuel Mass. Convenient sliders allow rapid input of personnel and baggage weights. Graphical displays—Moment Envelope, CG Envelope, and Aircraft Axis—provide visual confirmation of CG limits.
2. Takeoff Page – Computes Ground Roll and Landing Distance utilizing actual POH data. Variables include aircraft mass, pressure altitude, temperature, runway conditions and slope, wind conditions, and more. Additionally, the Wind Components Computer offers quick assessment of headwind or tailwind effects by adjusting wind direction and speed.
3. Climb Page – Estimates time, fuel consumption, and distance based on difference in elevation between takeoff point and flight level, as well as wind conditions, temperature, and altimeter setting. Displays rate of climb and climb speed.
4. Cruise Page – Determines optimal cruising altitude considering trip distance, flight level, power settings (MAP / RPM), temperature, wind, and atmospheric conditions derived from the POH.
5. Landing Page – Calculates landing distance and ground roll influenced by wind speed and direction, elevation, pressure setting, runway conditions, and slope. The Wind Components Computer allows quick wind component analysis similar to the takeoff page.
6. Stall Speed Page – Computes stall speeds in KIAS and KCAS based on bank angle and flap settings using actual POH data.
7. Setup – Enables loading and saving up to five aircraft configurations or scenarios. Users can email a comprehensive Mass & Balance summary or access tutorials via integrated video content.

The software can operate in two modes: "Individual Mode," facilitating independent calculation of each parameter; or "Plan Mode," which integrates values across pages for streamlined flight planning with a dedicated Flight Summary page.
