best chart i could find!
was deep within the flight manual of the 738 that i was able to look through whilst at the former excellairways in gatwick.
the title of the page, was performance enroute climb one engine inoperative 2 a/c packs on flaps up.
the lowest pressure altitude was 4000 feet. one can look down at the bottom at the outside temp-go up to the 4000 feet line and cross over to a gross weight set of lines-example-23 degrees C 4000 feet p.a. crossed the 68000kg line giving 1100 feet per minute rate of climb
i have not been able to access that chart anywhere else.
