How many PHEL curves are there?

Explanation:
The number of PHEL curves is six because the standard diagram used in this material shows six distinct lines, each representing a separate defined condition or operating envelope. You determine this by counting the unique curves on the PHEL plot or by noting the six labeled conditions in the legend. Four or five would omit a defined case, while seven would add a curve not present in the reference figure. So six is the correct count.
