Avionics rocks !!!!

Category III B approach and landing with auto land. Forward visibility about 200 feet. Cat III B requires (3) digital autopilots to be engaged and operating. If (1) AP fails, you continue the approach but your decision height (DH) and (RVR) runway visual range increase and your thumb is on the go-around (GA) button the entire time.

I'm sure that after watching this video you'll be able to understand the importance of GA button in critical landing when visibility is very less.

Don't you think friends that Avionics has increased the operational characteristics of an Aircraft ?
