Calculate and interpolate performance data using the actual values
from the Pilots 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, iPad Retina 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 Arrow IV has seven main pages:

1. The Mass & Balance (or Weight & Balance) Page


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



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 Pilots Operating Handbook you can
determine the optimal cruise altitude based on
- Trip Distance
- Flight Level
- Engine 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.
