Whats up here?


#1

So i was watching this Lear 60 flightaware track and he is flying to my home TVC but at only 27k. He also filed to leave in awhile and its the same altitude. I figured it was a mistake but he actually flew all the way here at 27k…anybody know the reason? pressurization isssues? can a lear 60 have sea level pressure at 27k maybe for medical reasons had to have it?

any thoughts?

I don’t know specifically about Lear 60’s, but in our 36’s, 28,000 is the limit for sea-level pressurization flights.

On a relatively short flight like that through busy airspace staying lower is the “shortest distance between two points” so to speak. You have the lower level traffic going in and out of the Chicago and Milwaukee areas. Then you have the upper level transcon traffic to/from the NE corridor passing through. It works out better for ATC to keep a flight like N574DA in the middle. Most of my 1 hr. type legs here in the SW are at FL270 to FL310, and sometimes lower if ATC dictates.

Thanks Guys. I did see on previous flights they have had that are only an hour or so long have been up towards 36k so thats why i was wondering.

May also have been an RVSM issue.
