Most aircraft can not meet the Climb Requirments when following the FAA Departure Procedures. However, many can meet the climb requirments if they follow the APG (Aircraft Performance Group) departure procedure. We use the APG departure, it allows us to go with a higher take-off weight, and temp. than what the AFM would allow. Plus it is perfectly safe and legal to do so. APG could be a whole other discusion in its self, but for further check
