>> Flap Asymmetry Tester Flap Asymmetry Tester

The AMI Model 104 Flap Asymmetry Tester is an intelligent, hand-held electronic tester that is designed to facilitate the testing and alignment of the left and right flap asymmetry switches on the Gulfstream GII, GIII, and GIV aircraft. Since it is powered from the aircraft and requires no additional power source, it also tests the integrity of the flaps electrical system.

This tester has internal electronic logic that can automatically move the flaps to set the position of the reference asymmetry switch to the leading edge of the 'A' contact, thus defining a known set point. It also has an extremely sensitive phase error detection indicator, and a circuit for detecting serious phase errors that could lead to a FLAPS LOCKED condition.

This tester allows the technician the ability to test both asymmetry switches while only requiring access to one side of the aircraft, either side. When viewing the ASYMMETRY SWITCH POSITIONS indicator, the asymmetry switch accessed and connected is defined as the unit UNDER TEST, while the opposite side is defined as the REFERENCE unit.
