CHART 1 - CLEAN AIRCRAFT (14,600 LB)

A.L.1	NOTE.-The airspeed at 40,000 ft. when cruising at maximum continuous power speed should be shown as
	260 knots instead of 310 knots.  The dotted curved line should be adjusted therefore to read 335 knots
	at 30,000 ft. (as shown at present) down to 260 knots at 40,000 ft.
