You’re both correct.
Vso is the stall speed OR minimum steady flight speed in a landing configuration at maximum gross weight.
It’s like saying the freezing point AND the melting point for water is 0 degrees C.
Don’t forget that these speeds are at maximum gross, and are still dependent on load factor. (i.e. in a turn or otherwise increasing the wing loading)
OK don’t answer to quickly. I give type rides for Citation XL pilots (I work at FSI) and they almost always answer this wrong.
You fly from point A to B, it’s 100nm. Then back to point A. You have a TAS of 100kts both ways. You have a 10kt tail wind on the way there and 10kt head wind on the way back. How long will the round trip take.
It’s not as obivious as you might think. Why not?
Don’t forget that these speeds are at maximum gross
The formula is:
New Speed = Old Speed times the square root of weight new divided by weight old. In Excel it looks like Vso*(SQRT(Wn/Wo). So that a Vso of 63kts @ 2600lbs is 53.85 @ 1900lbs
I also ask them the name of the Jetson’s dog BEFORE Elroy found him. NO GOOGLE cheating. 
Isn’t it 2:01?
A to B: 100 NM / (100kts +10kts)=110 kts = 54.5 mintues.
B to A 100 nm / (100kts - 10kts)=90 kts = 66.7 minutes.
66.7+54.5=121.2 minutes = 2 Hours 1.2 minutes
Dami,
don’t forget to factor in the time to eat the Otis Spunkmeyer cookies if B’s FBO.
Tralfaz! Former pet of the billionaire Gotrocks? Or was that the Flintstones?
God, the shit that sticks to your neurons whether wanted or not!
Yep, (I didn’t check your math though 
) everyone jumps and says it’s 2 hours, people assume that the 90kts and the 110kts cancel eachother out. The truth is you spend more time going slow then you do going fast.
Now how about the Jettson’s dog?
Let’s see… His name was Astro as far as I can remember so my guess for before would be Scooby Doo.
Nope
You’re kidding!
These are educated, experienced pilots?
That’s scary.
I know. But then again the last time they flew 100kts was 2000 hours ago. They do feel stupid when they do the math.
I would certainly hope so!
Is Tralfaz correct? Or did I get that from the Flintstones?
I just have a vague recollection of someone uttering a sibilant, rolling “Here Traaalfaaaaz” in a pseudo upper-class twit accent.
Tralfaz Got Rockets is correct 8)
Ah well, I got it half right! 
Where at FSI? I worked at TEB for 4 1/2 years
I almost took a job with FSI in Wilmington. I’d have a couple hundred hours in a Hawker 800 by now!
FSI Columbus. 5 years instructing in the XL, been an examiner for 3.5 years. We’ve got an
Ultra, XL, X, Falcon 2000, Soverign, (XLS, G200 with in next 6 mos.)
Best flying job I’ve ever had. After 5 years of being gone >35 wks/yr and instructing 8 hours/day for the 4 years before that. I’m home everynight. Couldn’t ask for anything more. Right know we’re interviewing, but I din’t think for very much longer. We’re going to be seating at 7 sims for quit a while.
Small world. I was actually involved in the certification of the Falcon 2000 sim in CMH
