Virtual KM count
It would be very useful if before starting we could input the average speed and start time as provided from the roadbook. Using that information the app could display a counter, that tells at which km I should be considering the given average speed and the current time.
This can give an idea if the pilot is late or early compared to the average speed.
This can be a feature that can be activated from the settings, and used together with the "start at time" feature. It would then require the user to provide the average speed as stated on a roadbook.
The virtual distance counter based off the average speed should be clearly displayed not to be confused with the gps partial and total distance.
