That was entertaining, but let's get back on-topic.
I hear the brakes on the 60XR are quite a lot better than the base 60. True?

The classic Brakes from the Lear 60 came from the Learjet 55. They are identical. There is a SB that upgrades the "classic" 2-rotating disc Brakes to 3-rotating discs. This SB also adds new Actuators to the MLG. The 60XR has the 3-rotating disc Brakes installed from the factory. I cannot make a statement on the operation, since I am no pilot.

Thanks Highfinn, useful stuff. :cool:
So, does this SB reduce the certified landing distances etc. to take into account the improvement in braking performance? :confused:

Almost had a brain-failure trying to remember why, but all I can come up with is that whilst very effective in real life, that SB does not permit you to apply those very much improved figures under commercial ops. Somebody will be along in a minute to explain why, no doubt...

implemented, not certified...yet...

Oh, in real life the updated brakes help you a lot more but it is not certified.

Just like the LJ60 is supposed to have had autoland capabilities (autopilot software) but certification was too expensive.

So it gives you a real life safety factor but you can not use this for legal calculations.
