Lets not get carried away here.
A Challenger jet is not a Cat D aircraft as far as approach category.
Very much possible that 14,000 plus high temperatures created a density altitude of 20,000+
TAS increases over IAS at 2%/1000’ so we could be looking at a TAS which is 40% higher then IAS.
250kts IAS would equate a TAS of 350 plus or minus wind.
A groundspeed of 350kts+ doesn’t mean this was a crew just blazing through the skies.
