2.1.5.5.1 Lever Actuation/Release Forces

Nominal force to actuate the levers is 21 N at the point of typical finger placement.

2.1.5.5.2 Closing sequence

To ensure proper operation, the ILM design provides features to ensure that the proper

closing sequence is followed. The load plate is placed in the down position, then the

Active lever engages the load plate tongue and is latched first. This is then followed by

the latching of the Hinge lever. This sequence is ensured by the sequencing tang on the

Active lever, and the fact that the load plate angle will prevent engagement of the

Hinge lever. See Figure 2-21 and Figure 2-22.

ILM lever closing sequence is

1. Latch Active lever first

2. Close Hinge lever second.
