Oh, I see. I'm pretty sure that's by design. The feature was designed so that you can indicate you're doing something at the waypoint at the beginning of the leg, purely so that we generate a STAY indicator in the VFR flightplan. So I suppose we considered the extra time being in the vicinity of the waypoint, and not as part of the leg itself, which follows as soon as you stop doing whatever you're doing.

The total time does increase, but the leg time does not.

To attempt to reproduce this, I created a two-leg journey. I gave the second leg 30 minutes of extra time at its start. I observed the total time, at the bottom right of the screen, increased by 30 minutes. I then opened the PLOG and observed the 30 minutes of extra time accounted for in the totals column, and in the cumulative time in the ETA column. What am I doing wrong?

If someone is holding for aerobatics, for example, that will consume a large amount of fuel compared to regular cruise.

True, but using the current power setting is better than defaulting to 0. Also, if the fuel consumption is radically different, a different power setting could be set for that individual leg.

We can't make fuel consumption calculations take account of the "extra time" because we don't know what you'll be doing during that time. If someone is holding for aerobatics, for example, that will consume a large amount of fuel compared to regular cruise. I had thought the ETE was updated to take account of extra time; which specific ETE are you looking at? The one on the PLOG?

I would actually find that quite useful -- but only if the fuel consumption and leg ETE reflected the additional time.

It was a function introduced for the Olympics, which does little other than indicate to the VFR flightplan system that you will be holding in an area for unspecified manoeuvring.

What is the intended function of setting "Extra time at start of leg" under "Leg properties" in Skydemon Plan?
