There are two methods in Scott Plot® to add ETPs to your route of flight.

Plot Automatically

Scott Plot will read your flight plan and attempt to plot your ETPs graphically. If Scott Plot is not able to read some or all of your flight plan data, you will be able to edit or add ETPs manually. Your flight plan will be presented in the upper right-hand corner of the screen to enable validation of all ETPs plotted graphically.

Automatically plotted ETPs with the flight plan shown in the upper right and ETP cards listed below

Once the ETPs are located within your flight plan, Scott Plot will list the number of ETPs found, your flight name, and the method they are organized. By default, ETPs are sorted by your flight plan order. You also have the option to sort the ETPs found by Route Direction or ETP Type by tapping the Sort button.

Plot Manually

If Scott Plot is unable to read some or any of your ETPs, you will need to plot them manually. See ETPs by Lat/Long from Flight Plan to enter values from your flight plan, or Calculate New ETP to have the app calculate one from wind and true airspeed.
