You're the Captain DD and if you want to make that decision , so be it! But can you justify it at the subsequent enquiry if ATC 225'd you instead of giving you a "cleared to land" for tape purposes?
I mean, where does one begin and end with this "common sense licence" that tells you that you have covered every single possibility, in a short space of time, and are going to breach regulations because you "can't be bothered going around"? Altho, as you have pointed out, that's not your scenario.
Others will beat me to it ,no doubt, and give other examples, but what about these for you to consider...
1. CNS has a short x/strip if I remember correctly. What if a lightie decided to T/o without a clearance too?
2.What if a lightie that you haven't seen is waiting to line up on RW 15 and decides to do so without a clearance too?
Remember the basics, of course you do. Safety..Comfort..Schedule...Economy!
