4.1 INTRODUCTION
This chapter contains general flight-line maintenance and troubleshooting procedures for installations
interfaced to WX-1000/SKY497 display or an alternate display. Removal of components is on condition

(including connectors) are installed, removed or replaced, the TRC must
be calibrated to the directional antenna (refer to paragraph 4.4.3).
