Performance graph for non-standard conditions

The following graph shows the performance drop with increasing
flight altitude. The curves show the performance at 5800, 5500,
5000, 4800 and 4300 rpm, at full throttle.
At deviation of temperature conditions from standard atmosphere
conditions the engine performance to be expected can be calcu-
lated from the performance indicated, multiplied by standard tem-
perature, divided by actual temperature in °K.
