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.

Important Note

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 Results

 

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.

Options

 

Default Airplane

Touch the button and select the Default Airplane to be displayed when the App starts

 

Default Station

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.

 

Wind Speed

Select either Knots or MPS (Meters per Second) for wind speed measurement

 

Temperature

Select either Celsius or Fahrenheit

 

Distance

Select either Feet or Meters for distance measurement. This option is used for both Pressure Altitude and the Takeoff & Landing distances.

 

Weight

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.
