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.
