August 23, 20187 yr Hi, I am trying to use the WEATHER RADAR TEST SWITCH, but only get the following display on the ND: "WXR TEST" in orange and TEST -2A in blue, but no colored sweep lines. The duration of the ND display (wxr test and test -2A) is very short (approx 3-4 sec). I believe that the sweep takes longer than the duration of the weather radar test. Sometimes a 45 degree colored sweep can be seen. Anyone know if there is a adjustment for the weather radar test duration? Thanks for assistance Brgds Juergen Mader
August 23, 20187 yr I test every flight... always works. WXR has to be on, I usually do the test after leaving ramp while taxiing. Dan Downs KCRP
