Lyman, I know what the RTLU does. My "what on earth?" question is, how can you possibly be considering it in any way related to this accident?
I'm sure I've already noted, I'm not a 330/340 guy... I'm an AME, licenced on the 320 family, but the only bigger Bus I have on my licence is the 310... so I'm a little unfamiliar with the 330 panel..... I understand the beast had all the attitude info they needed, and that it was airspeed info only that they were missing for a short time. Am I wrong?
