    The 172R I'm flying has an endurance chart which uses standard temperature. Do I assume the chart means 15C at every altitude in the chart that goes up to 12,000 ft? Or does the chart mean that it's calculated sea level at standard temperature and the rest of the altitudes are based on standard lapse rate?

    Standard lapse is applied to the charts IIRC and they will typically have notes on adjusting for non standard conditions.

    Please post the chart. I just looked at one and it made the temps clear in each "box" of the chart. Yes, the ones not at sea level were different temps than the ones at sea level. This was for my check out quiz for a 1973 Cessna 172 which had a tiny POH.
