gmangnall Posted October 4, 2022 Posted October 4, 2022 The DMT tracker is limited to 450 degrees of roll (A1-AV8BB-TAC-000 chapter 1-page199) after which the lock will be broken. extract is as follows: The signal data converter also receives roll signals form SAAHS which are used to stabilize the receiver/processor roll gimbal and thus the ground scene. However, because of mechanical constraints, the DMT is limited to 450° of roll. If the aircraft is rolled beyond these limits, the DMT will gimbal and break lock. Therefore when the DMT is operating, aircraft roll should be held below 450°. If the DMT is rolled over (exceeds 450°), the pilot can undesignate (using nosewheel steering switch on the stick grip), which commands the DMT to reset to zero in roll. The target can then be redesignated.
