Hmmmmm, very interesting. I guess I wouldn't be surprised at all if an OPTIONAL race/gender section was included at the end of the questionnaire for "strictly statistical purposes," but I can't imagine how they could legally make this a mandatory part of the application.

lol you'll develop an ear for that after some time. most controllers i know can have multiple conversations going on at once and follow along on all of them. Def takes time to develop though, I'm surprised they test that on an entry exam
I'm going to the haunted house of Muskogee in order to prepare for the test. lol. It seems cool tho.

An airplane with a ground speed of 250kts Is flying into a headwind. If it has traveled 330nm in 90 minutes. How fast is the headwind?

What's the fastest way to calculate this in your head?

I dont know if this is right but...I found the distance in 90 mins at 250 and then found the difference from 330nm

Right that's what I did. I divided 250 by 60 to get the miles per minute then multiplied that by 90 minutes but obviously 60 doesn't go into 250 evenly so I was wondering if there was a better way

Well you are dealing with half of an hour, so what I did was add 125 to 250 then subtracted that from the 330. Took seconds to do

Did you get the same answer tho? It may not be the right way. Have to wait until someone else chimes in. But I didnt do too bad on the AT-SAT using this method

Shouldn't the question say the plane has a true air speed of 250 knots? If its ground speed is 250, I don't see any way it's going 330 nautical miles in 90 minutes.

Yes the answer is 30 but I'm trying to find the best way to do this in your head
The plane goes 330 nautical miles in 90 minutes. So it's ground speed is 220 knots each hour. Or 2/3 of 330. The ground speed is 220. The true airspeed is 250. The difference between those numbers is 30.

OK so best way is to break it down thanks

Question should have said "true airspeed of 250kts" I'm pretty sure...

(90 min = 1.5 hours)
330/1.5 = 220 (D/T=S)
250kts - 220kts = 30kts

Headwind of 30 knots is the answer.

Well I failed to find the distance traveled per min first but the process afterwards is still the same. I got 30 when I did that way.
