ICAO has elected o present the climb requirement for a SID in a slightly different fashion.They specify in DOC 8168, PANS-OPS, Aircraft Operations, a minimum climb gradient of 3.3% for the same segment of the flight.
A quick calculation shows, that these two climb requirements (FAA AIM 200' and ICAO) actually are identical.
1 nautical mile=6.076 feet, so 3.3% equals 200 feet per nautical mile.
This 200 feet per NM way of expressing the minimum permissible climb perfomance for all SIDs where a crossing altitude or a higher gradient is not prescribed, is very convinient for use in the cockpit.
in other words, when flying a SID, you are only guaranteed not to hit anythingif you climb with at least 3.3% or 200 feet per nautical mile until reaching the MEA.
