The B737 can become airborne to 500' and still land on the same runway, within 4000m
Sure it can, but then, if you use everything boeing provides you cant. Ambling along with a leisurely 73% N1 while waiting until that 169kts V1 rolls around which lets you rotate within the last 300m of those 4000m is a very real boeing proposed takeoff profile. Certainly would not love to see a past V1 rejected take off on that one.
@alf5071h re you point 3. Boeing posted us an advise that any IAS disagree message in the high speed phase of the take off run (past 80kts) is no reason for a take off abort. Take it in the air, deal with it and come back if needed. It was given again after a V1 reject caused a runway overrun.
And that was about a real IAS DISAGREE message, not some perceived speed trend vector anomaly during rotation.
As you are probably aware boeing, the same as airbus by the way, advises pilots to be go-minded and only a very small list of reasons for a high speed reject.
