## What is DA40 180?

Gyronimo Performance Pad -Diamond DA40 180-
The ultimate EFB computer for Mass & Balance and Performance.

Calculate and interpolate performance data using the actual values 
from the Diamond DA40 180 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.

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 DA40 180 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.

- 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.




For iPad 2, iPad 3 (iOS6 recommended)

### 5/5 — Excellent Interface

*2022-01-27, version 3.4*

Everything about this app is great.  Very satisfied

### 1/5 — I don’t recommend it to any one pilots or student

*2020-03-29, version 3.4*

This app is not as it looks, I don’t recommend it to any one it’s useless don’t waist your money

### 5/5 — Great App for Calculating Distance and W & B

*2018-10-13*

Easy to use and ties back to POH for DA40

### 5/5 — Solid App

*2017-08-19, version 3.0*

The price is a bit steep, but that app does everything you might need it to, and the interface is very friendly

### 5/5 — Great app

*2013-11-17*

Bought this app recently. It's proven to be accurate in its calculations. I use this application to double check my own calculations on pen and paper to ensure that they match up. It gives me extra piece of mind and adds only two or three minutes to flight planning and more confidence walking out to the aircraft for each flight.
