Abstract: A computer implemented lean assist function monitors exhaust gas temperature in a plurality of cylinders in an engine along with fuel flow. The lean assist function automatically detects whether the pilot is leaning for best power or best economy and provides an indication to the pilot when the desired fuel mixture has been achieved based on the monitored temperatures.

Abstract: An ejector mechanism is provided for ejecting a field replaceable module from a receiving location in a carrier of a modular system. The ejector mechanism can include a lever pivotally mounted on the carrier and including a formation for engaging the field replaceable module to eject the field replaceable module. The lever can also include a clamp for engaging with a handle of the field replaceable module. The lever can include a trigger that acts to release the clamp and to cause a protrusion to project from the lever as the formation for engaging the field replaceable module. Cable management can be provided, for example in the form of at least one wire loop receivable in a locating hole in the lever.
