Krusty the GA procedures had been altered by moving the order in which things are done. The crew did a second GA off 16 and got it right. What was the difference? The PF actually moved the thrust levers to the TOGA detent. The cockup had very little to do with the GA SOP and a lot to do with the PF not moving the thrust levers to the GA detent and not reading the FMA ,and to compound the error by not climbing to the GA Altitude. Even at FLX/MCT, it would have had sufficient performance to get to 4000'.
