At what point do 121 crews delay arrival/ dept due to WX?

[BobDDuck]

Well, this was in a 210, it doesn't take much. I don't know what to tell you otherwise. I was stuck in a shallow descent for a few minutes.

I hope you weren't the guy in a cessna the other day reporting severe turbulence in the traffic pattern and then requesting vectors for another practice approach.

But, the downdraft hitting the ground can be extremely powerful and go all directions from the storm at a high rate of speed. Being in the OMA area, he more than likely encountered the resulting downdraft straightline winds from a supercell. When a supercell implodes on itself and falls apart, all that energy falls to earth an has to go somewhere. Depending on the size of the storm, it is completely possible these winds were felt as far as 40 miles ahead of the storm.

Windshear is something that happens quickly as in a few seconds otherwise it's not shearing..."couple minute descent" doesn't sound like wind shear to me. Just IMO.

Completely agree. I just assumed what he experienced was called/named the wrong thing earlier in the thread.

Nah, it was definitely a steady 700-1000ish steady downdraft, resulting in about a 200ish fpm descent. Nothing crazy, but it does make you think "Hmmm..."

So lemme get this straight, you think you were in a thunderstorm downdraft 40 miles away from the storm. OK.

You got me, I'm a compulsive liar.

Just misinformed.

Not that, just saying that you got in a downdraft from a tstorm 40 miles away from the cell (at or below 10,000 feet I'm assuming) says louder that you need some more learning.

You/your Captains let dispatch fly your airplane? Fascinating.

Nahh, I'm just joking around. Every captain I have flown with, I have worked together to make a decision, while watching other planes and listining on the freq of arriving and departing traffic.

I wasn’t there, so I can't speak for the guys who were launching that day; but in my experience most 121 drivers, including me, won't go unless there is a reasonable way to get around what is approaching the field. I'm guessing that is what was happening here. Perhaps what looked good on radar and what they perceived to be a reasonable, safe pathway out, turned out to be less than desirable. Once the storm is overhead or if it is close enough to create a threat, I will wait it out. I have taken plenty of delays for weather and see other aircraft do it all the time too. Every situation is different. A single, level one or two boomer in the neighborhood of the field isn’t going to concern me like a TS all quadrants type of situation.

A 200fpm downdraft in a 210 at that!

Some clown does that every single time we have Santa Ana winds in SoCal. "Hey uh, severe turbulence in the Santa Susanna Pass below 3,000'."

You think?

Haha "fuggit" is now my word of the day.. And I would love to see one of us on leg 8 not say fuggit
