Calibrate Dock Latch (No Aircraft in Dock)
This alarm is covered by this guide. Background
Section titled “Background”If there is no Aircraft in the Dock, use Fleetwrangler to calibrate the latch. For safety reasons, the Application Software team will need to explicitly enable latch calibration for Fleetwrangler (see step 1). If there IS an Aircraft in the Dock, see Calibrate Dock Latch (Aircraft in Dock).
