When to Use the Takeoff & Landing Distance
The current POH/AFM must be the source for takeoff and landing distance calculations
Use this screen when you want to get an idea of performance based either on current conditions or on conditions that can be specified by the user
To get a feel for how changing conditions will change aircraft performance
The T&L App makes it easy to watch how aircraft performance changes based on changing environment conditions.
NOTE: Unless otherwise stated the calculations are based on level, dry pavement.
The modeling techniques used to make these calculations vary based on the performance data supplied by the manufacturer. Some techniques allow more flexibility and speculation than others. For example it is possible to set conditions to extremes that could never exist in real life. In some cases it may even be possible to show the airplane takeoff in a negative distance. The extreme cases and extrapolations make for interesting conversation, but care must be taken to consult the AFM/POH supplied by the manufacturer to make sure the results make sense.
How to Use the Takeoff & Landing Distance
To calculate the Takeoff and Landing distances
Touch the button at the top to select an Aircraft
Touch the Station ID (Blue Button) at the top/left of the screen and the Airport Search screen will be presented
Enter a few characters from the Station ID or the Airport name or the Airport City
Select the Airport by touching it
Most airports will have the runways defined.
Calculations for additional runways may be added by clicking on the desired runway button on the right side of the screen
If a runway is selected that does not exist in the database the calculation will be performed with the runway distance set based on the default length entered on the Options page
Enter the Weather conditions. If the selected Airport has a METAR station the current weather can be obtained by touching the Get WX button.
The runway ID with runway Length and Width (if available)
Wind H Headwind, calculated based on the wind direction and speed and the runway heading
Wind X Crosswind, calculated based on the wind direction and speed and the runway heading
Tkof/Land Takeoff and Landing Ground Roll
Remaining Runway distance remaining after the Takeoff or Landing Ground Roll
>50' Takeoff or Landing total distance to clear a 50 feet obstacle
These distances are expressed in either Feet or Meters depending on the selected Option.
The current METAR data for the station can be obtained for use in this calculation by touching the Get WX button.
Touch the button and select the Default Airplane to be displayed when the App starts
Touch the Station ID (Blue Button) button and Select the Airport used when the App starts
Load WX at Start
Turn this switch ON to have the METAR for the Home Airport automatically load when the App starts
Default Runway Length
Enter the runway length to be used for runways not defined in the database.
Runway Remain Warn (Yellow)
Enter the distance to be used to determine if the Takeoff or Landing distance should be colored Yellow if less than this distance is available after the takeoff or landing roll
Runway Remain Min (Red)
Enter the distance to be used to determine if the Takeoff or Landing distance should be colored Red if less than this distance is available after the takeoff or landing roll
Begin Takeoff Roll
The point on the runway where the Takeoff Roll Begins
Begin Landing Roll
The point on the runway where the Landing Roll Begins
Dry Grass Default
Turn this switch ON to set Dry Grass as the default runway surface
Default Dry Grass Takeoff %
Enter a percent of the takeoff distance to add for a Dry Grass runway surface. This number is used if the Dry Grass option is selected and the manufacturer does not supply a number to use.
Default Dry Grass Landing %
Enter a percent of the landing distance to add for a Dry Grass runway surface. This number is used if the Dry Grass option is selected and the manufacturer does not supply a number to use.
Select either Knots or MPS (Meters per Second) for wind speed measurement
Select either Celsius or Fahrenheit
Select either Feet or Meters for distance measurement. This option is used for both Pressure Altitude and the Takeoff & Landing distances.
Select either Pounds or Kilograms for weight measurement
The database used in the App contains over 10,000 airports. If you would like to review the list of airports please visit the CFI Tools Airports web page. Not all airports have runways defined.
PLEASE NOTE: The source of the METARs used in this App is NOAA’s National Weather Service Aviation Weather Center. It can be found here:
If the METAR station cannot be found with this site, it will not be available in this App.
