• transition from TRU HDG to HDG MAG results in a green box around

HDG MAG for 10 seconds

• when TRU HDG is displayed and the airplane descends more than 2000

feet at a descent rate greater than -800 feet per minute, an amber box is

drawn around TRU HDG; the box flashes for 10 seconds, then turns

steady amber.
