- inferiorhuman 8y agoBoeing were telling pilots that this warning message would alert them to that kind of problem before takeoff. I doubt that, the alpha vanes aren't particularly useful until the plane is actually moving at a fairly decent clip.
- AnssiH 8y agoYes, it does not work. According to the OP article, Boeing said to American Airlines pilots in November that the warning would work on the ground, but later said it in fact does not.
- phire 8y agoBy before takeoff, I assume that means "during the takeoff roll" And I hope that also means "before V1". I know the DC 8 couldn't do it's elevator check until it was moving quite fast, as there was no direct connection between the pilots controls and the elevator and it couldn't respond without airflow.
- danaliv 8y agoWhat speed is that? I don’t know about 737s in particular but some AoA sensors work at speeds as low as 20 knots—far less than V1 on any runway a 73 is going to use.
