A 60 has TRs. A CJ4 doesn't. Which stops in a shorter distance, TRs included?
You tell me-I have no idea. Also compare usefull loads, range, etc. Which one would be more affected by adding a couple hundred pounds more equipment? And how many corporate jets include TRs in landing distance computations? What's the cost with or without? Point is, EMB 300 does just fine in most airports any fractional goes. Even with Part 135 planning restrictions. In the minds of both sides of the equation, both parties really don't have an issue with lack of TRs.
One can argue all jets should have at least 3 engines to avoid second segment issues at places like Aspen, Eagle or Telluride. OEMs like to sell more jets, while pax like to buy more bang for the buck. There is a cut off for extra expense that all are willing to accept.
