How is ETE calculated in World Map?

The world map shows the distance and ETE between two end points in a flight you’ve created. However the calculated ETE seems inconsistent between aircraft. For example, I planned a direct route of 94nm between UT1Q and UTTT. Here are some aircraft, along with their cruise speed as shown in the aircraft selection screen, and the calculated ETE for this flight.

  • Daher Kodiak: 174 KTAS, 01:01
  • Mooney M20R: 174 KTAS, 00:32
  • Carenado 170B: 107 KTAS, 00:57
  • Cessna 152: 105 KTAS, 1:24

Why such a wide discrepancy when all other conditions are the same? Why are faster planes taking longer? Are the stated cruise speeds incorrect or is something wrong with the way MSFS is calculating the ETE? Or is it something I’m doing wrong?

Would say, the Asosbo aircraft will be calculated correct and the Addons probably not.

That sounds like what I’ve been suspecting. In fact I just flew the flight in the Kodiak and logged less that 35 minutes, which puts it in the same ballpark as the Mooney.

I have to do more testing but my current hypothesis is that the default aircraft are fairly consistent when it comes to ETE, but for the 3rd-party aircraft MSFS’s ETE is not to be trusted.

Answer direct from Asobo on how ETE is calculated:

Thank you! This is the information I was looking for. I guess the 3rd-party developers need to triple-check their simvars.
