No,
Unfortunately, the US version of the XL/XLS and I'm pretty sure the XLS+ do not have a warning for Parking Brake set.. The No Takeoff Light is not triggered by the Parking Brake position on the US Models of the XL/XLS. Only the EASA versions have that warning. I call "Parking Brake set,... Parking Brake released" as part of my flow because of the Oroville XL, CA overrun, an Encore+ in the Bahamas, and now this. That being said, IMHO, this airport's runway was WAY too short for this jet unless everything was PERFECT. No 135 Operator would be allowed to fly an Excel into and out of a runway this short.
I know that this would be a tough conversation for a Part 91 corporate pilot to have with "the Boss", but sir this jet needs a longer runway. I met a corporate guy in SLC that told me that they fly a Piaggio in and out of Palo Alto and my VNR alumni and myself couldn't believe it.
RIP to the crew and the passengers.
