Tech Insertion: today's efficient, lower emissions aircraft power

CFM stays well ahead of the toughest environmental regulations by incorporating new technologies into the production standard and by re-invigorating mature fleets through upgrade kits.

Most recently, CFM introduced Tech Insertion, breathing new life into the CFM56-5B and –7B fleets. Tech Insertion engines produce 28 percent fewer NOx emissions than the base engines they replace. For each combined airplane takeoff and landing, this reduction is the same as eliminating the NOx released by more than 350 passenger vehicles idling for an hour.

If today’s CFM56-5B-and -7B-powered fleets were replaced with CFM56 Tech Insertion engines, annual carbon dioxide emissions would be reduced by an amount equal to:
» Removing 66,000 cars from the road for a year; or
» Adding 93,000 acres (37,637 hectares) of forest.
