And...if you get REALLY bored on a ULR flight and the airspace allows it, pop 1000 into the step size and it’ll recommend steps in 100 ft increments, but only if you are super bored. Recommended is the number to use as long as the winds as accurate and you take account of lower as well as higher Alts. I’ve had wind info for 280 up to 400, but stayed at 260 for 2 hrs across Oz one night and saved 10 minutes and at least 1 tonne of gas thanks to getting Pireps of the actual winds...another thing to do if you are super bored.
