CH 47 F question

[Capt Bob]

Quick question, while flying the CH47 during sling load ops. I was using the pilot MDF set up for Nav with the flight director. Noticed a red box pop up with the letters RA inside. I get the feeling it's the radar alt? anyone have any insight. thx sorry if I posted in the wrong place

Yes, it's most likely a radio altimeter warning.

"Correct. The red RA flag will pop up when the RA fails or senses erroneous data. Can happen with slingloads sometimes because the load is reflecting the radio signal back to the antenna on the bottom of the aircraft".
