There are two meters during a Daxterjack. The first is Grip, representing Daxter's ability to remain on the plane without falling off. This meter reduces gradually by itself, but will go down significantly if the wrong button is pressed. If completely depleted, Daxter will fall off the plane. The only time it remains fixed is while Daxter is crawling through the plane's interior to reach another section. The second is Engine, representing the target plane's remaining integrity, which is reduced while pressing buttons. There is one Engine meter for each engine that Daxter is working on. Upon completing a Daxterjack and depleting the last meter will cause the ship to explode.
