## What is Cirrus SR20?

Gyronimo Performance Pad -Cirrus SR20- 
The ultimate computer for Mass & Balance and Performance. 

For SR20 Aircraft Serials 1268 -2016 Analog or Avidyne Avionics System. TOW Max 3000 lbs

***** NOW WITH PROFESSIONAL LOAD MANIFEST. ***** 
Sign the manifest on your iPad and send it via email.

Calculate and interpolate performance data using the actual values 
from the 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 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 


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 
- MAP / 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 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.

### 5/5 — Love these Geronimo apps

*2022-09-28, version 1.7*

Long time user of the Geronimo apps. So simple. So easy to pick up and run scenarios for all the most popular single engine piston planes. I have the SR20, C172 and DA40 apps. All of them are flawless. Thank you for making this! Makes W&B and performance planning fun and easy.

### 5/5 — Every Cirrus Pilot Should Try This

*2018-03-24, version 1.6*

Simple, great graphics, clear user interface.  
I have cross checked with the POH and values are all within a pencil line with on any paper graph. 
Most importantly, because it is so easy to use, you will look at if before every flight.  Great for ‘What if’ armchair flying.
