Looking for help on ATPL - Equal time point to alternates.
The basics I have:
Flying from point A to point B, where is the equal time point to get to A or B?
I can do that in still air and with wind using the formula:
Dist to ETP = (total Dist X GS Home) divided by (GS out + GS Home)
Where I am having problems and can’t find the information is
Flying from point A to point B, where is the equal time point to return to A or diver to the Alternate at point C or what is the equal time point to 2 different alternates when flying along route A to B I need to be able to this in both still air and wind.
Is there a way of working this into the above formula or does it need to be done via plotting and if so how?
Any help would be greatly appreciated
