Snow Storm





Position: De-icing Pad; KJFK (New York)
Pax on board: 150



Why me? What have I done to tick off Zeus? Another major snow storm and I am in the geometric center of it. Everything in my world is at the edge of the envelope... Right side, left side, upside, downside.

Minimum fuel, maximum gross weight, minimum icing fluid hold over time, maximum snow accumulation, minimum braking action, maximum crosswind component for an icy runway, and on it goes... The thing that really worries me is the big-eyed children that look into the flight deck when their parents tell them, "Look, that's where the pilots are..."

I decided to be pro-active before we pushed from the gate, i.e., I called my dispatcher via cellphone. I asked him if he remembered a certain incident involving another airline in these exact circumstances. After a mini-review of the bad press that airline received, I told him that there is a strong possibility of that very thing happening on our watch. Outside, the snow flakes are as big as quarters and the visibility is less than 1/4 mile. According to my Pilot Ops Manual, that is heavy snow.... No, wait a minute; a little foot note at the bottom of the page. If there is fog with the snow (there is) then the snow gradient chart does not apply. It becomes captain's judgement... Oh, that is just great.

I will make it semi-official on the recorded line. I tell my dispatcher that I will be more than happy to try to get airborne (that is what I get paid for...), but in my opinion, we should think about canceling the flight. He puts me on hold for a few minutes...


"We want you to try."

"OK."

Twenty minutes later, Ice Man (two trucks) is blowing away the snow drifts (on top of the wings) with hot de-icing fluid. The snowfall is heavy; I don't care about the foot note. I tell the co-pilot, "This is not going to work."

Ice Man is starting to apply hot anti-icing fluid on top of the de-icing fluid. Fi-Fi's engines are idling, burning 33 pounds per minute. We are eleven minutes away from bingo fuel. I am thinking about the possibility of getting our same hotel rooms back. There is no way we are going to get airborne. We will be lucky to get a gate to unload the passengers.

Ice Man is finished and tells me we are clear to check the flight controls and taxi. The co-pilot says, "Boss, I think it is letting up a bit." He is right... The snow fall is less than heavy now. Instinctively, I look toward the runway. There is no one down there! This might work...

The tower clears us to taxi... The snow flakes are swirling in Fi-Fi's powerful lights. The co-pilot is reading the taxi checklist and I am responding as fast as I can while actually checking the switch, button, lever, or magic knob. I figure we have about three more minutes before the very expensive Type 4 anti-icing fluid becomes ineffective.

We are cleared for take-off; I look out my left side Plexiglas at the outer wing surface. It is shiny and green from the anti-icing fluid. Perfect! The runway forward visibility is 1/2 mile. It is the co-pilot's turn to fly... Yep, he is 25 years younger and has much faster reflexes. I give up the controls after we are lined up and remind him to clear the engines for at least ten seconds. This is to suck any de-icing fluid or snow through the engine that might be in front of the compressor fans. He brings the engines out of idle and holds the brakes by mashing on the top of the rudder pedals. Fi-Fi is not cooperating, though. She is sliding forward on the icy runway in spite of locked main gear wheels.

"I can't hold it."

"Let her go."

Brakes released and thrust levers to the forward stops. Holy Moly! The engines increase to maximum thrust in a few seconds and shove us back into our seats. The exhaust temperatures are amazingly cool. The noise level is higher than normal because of the cold air and snowflakes being ingested into the compressor section. Happy engines... happy captain. Go baby, Go!

I can feel the wings load up in the seat of my pants, always a welcome sensation in weather like this... Vee One Rotate. The co-pilot breaks the nose gear free and the mains follow. Before I can call out "positive rate" we are climbing in excess of 1500 feet per minute through a snow tunnel illuminated by millions of candle power. It is, well, simply amazing.

In a few minutes we are in the clear, underneath the star canopy, with the snow clouds falling away rapidly. Four hours, eleven minutes to the next runway as The Electric Jet continues to climb into the flight levels.

Life on the Line continues...

Another great post, Dave. I guess it was warmer where you were heading to...

KJFK was *nasty* Monday. Looked a lot better yesterday. Love seeing the EK A380 there!

Captain Dave, I feel bad for you and all New Yorkers. Here in Bangalore, India, we are at 100 Deg F by 2pm in the afternoon. Some of the intercontinental flights (eg. to London) have a weight problem due to their departure slot which is at the peak temperature and the fact that Bangalore is at 3000ft. MSL. How ironic is it -- you wish for heat and we wish for cold. Life around the world continues :)

On the edge of my seat again, Dave. Amazing stuff.

Great, great! As if one is sitting in the captains chair!!
Thanks!

Ed Skinner said...

Uhm, no thanks. I'll call the airline and rebook my seat for tomorrow then spend another night in the hotel and see how it looks tomorrow.
I wonder what's on HBO tonight?

Spencer said...

Dave...as a frequent flyer, I wonder what thoughts go through the pilot's head in weather like that...I now know! Being from WNY, that is a LOT! Another great post...thanks for the great reading!

You are so damn good at telling a story. It's gripping!

Sounds a lot like what the flight crew on my flight out of DCA back to MKE (on Midwest) were probably thinking Sunday night.

froid said...

Following your posts for years (yes, years) now and every one is worth it. Keep it up.

Tim G in MN said...

"We want you to try..." That's pretty ominous. I don't envy the position you are in balancing the safety of your passengers against the pressure to perform up to the company's bottom-line expectations. As a passenger, I'm not sure I want to know how marginal those decisions are... but I'm addicted to your writing so I'll have to deal with it.
Thanks for another great one Dave!

What a wonderful thing you do Dave. Actually two wonderful things. Thanks.

John said...

Yeah, I hope the weather was warmer wherever you were heading! I bet it was beautiful to break out of that snow storm. :-)

For anyone interested, there are some beautiful pics of the salvage work on USAir 1549. This guy had complete access.

New reader, and I have to say that I find each and every post very gripping. Great post keep going! Happy flying!

Amazing description... long time viewer here, finally saying thank you very much for sharing. Great stuff.

David Horn said...

Absolutely awesome as usual, Dave. I passed my IR in the UK two weeks ago and start on the 737-400 sim next Thursday - can't wait.

For a budding pilot your blog is absolutely gripping and reminds me every time I read it why I chose this career. :-)

Please keep on writing!

gh said...

Fabulous post!

Dave! I was wondering if you could consider publishing more than one picture per post?

LMH said...

Dave! That is scary! How often is it that a Captain makes the wrong decision? Obviously, the crew flying the plane is thinking about their safety as well, but it's still disturbing that such a decision relies on one person ultimately. I flew what I suspect is your airline to FPO this week, and I wondered if it was you. I thought about your blog, ESPECIALLY when I saw the captain looking under the Electric Jet for signs of metal fatigue, etc. I thought of a post where you wrote about doing that in the cold. I'm sure it's not so bad in the Bahamas!!

Thanks for giving us the REAL life on the line stories! That was just amazing reading!

Another great read. I was in Manhattan on Tuesday and you would never know it snowed! They have some serious snow crews. Keep the posts coming, very entertaining for those of us who've been grounded by the economy.

If the runway is so contaminated that a plane loaded to MTOW is sliding uncontrollably even with full brakes set, what's going to happen if you need to RTO on that same runway?

dave said...

anonymous 926: it is usually very slippery at the departure end of the runway where anti-icing fluid is lying on top of snow. Other than that, it is whatever the captain thinks is safe.

C said...

another awesome post Dave! we had a winter wonderland near KMSP last week - went from an overcast winter day to a snowstorm very quickly. keep up the posts!

DeeJay said...

When you retire you simply MUST write! You have such a talent for writing as well as the obvious talent for flying. Once again bringing it home to us mere passengers how much goes on up the front end. You guys get my vote every time

yyz-ramp-rat said...

Lucky duck! You got the snow, all we got was the clear and the *cold* Tuesday night. It was nice outside to start the shift and by the end of it, I was in full winter gear (layers upon layers - like an onion, or an ogre).

Today? +15C and OVC.

Great post! I thought of you the other evening as I was running a workout on a running track about 5 SE of SFO. They were using the 19s and this really unusual left-climbing-turn out over the track where I was. The rain and wind were swirling and you could almost see the sheets of water illuminated by the "millions of candlepower" on the lower-than-I'm-used-to jets. Not quite the same as your swirling snow, but about as nasty as it gets around here.

Keep writing!

Fabulous narrative Dave! I felt like I was inside your head the whole time.

Phew! That was nerve wracking.

Aviatrix said...

Ah, I love that post. I love it when the weather changes enough --one way or the other-- that I get out of making the really hard decision. But I don't get paid as much as you, so I always go for the chicken option.

MadeItHome said...

Great post, I was attempting to fly back to the UK from JFK on the March 1st. You were lucky to get out. The 777 I was one got de-iced twice, made two attepmts for the runway, both of which were hampered by ice build up. The captain said it was falling faster than they could get rid of it. After 2 1/2 hours taxiing around jfk and having burned 11000 lbs of fuel according to the co-pilot, they eventually cancelled our flight at 3am! Whilst sat on the plane, I was wondering if you'd be experiencing any of the JFK snow that week - seems you did!

Jay said...

""We want you to try..." That's pretty ominous. I don't envy the position you are in balancing the safety of your passengers against the pressure to perform up to the company's bottom-line expectations. "

I'm not sure Dave was saying that dispatch wanted them to "try" to see if the plane will fly. I think Dave was concerned that the plane would be loaded up and the heavy snow would necessitate another deice if the plane sat for too long in those conditions. Or, that he would get deiced and then sit in a traffic jam, the snow would accumulate, he would have to deice again...repeat (in that case, it would be easier to cancel ahead of time instead of having to sit on the tarmac with all those passengers...and THEN have to cancel anyway).

Dave wasn't "taking a chance" on flying (i.e maybe it will, maybe it won't).

Dave can jump in on this one.

Dean said...

Great post. You bared your teeth in this one. I liked it. Another thing I like about your site is that you haven't gone adshare and presented us with all those ugly pop ups and banner ads. Clearly, you are in it for the sheer molten core.

ArtZ said...

I love it, Dave! The go/no-go decisions sure don't vanish as you move up to the Electric Jet from a smaller plane but they are a whole lot more electrifying with your writing style and the added power and the "boatload" of people in the back. I can identify with the brakes-won't-hold-her situation, though, having tried to run up my Arrow on an icy taxiway at KSYR.

Rich, UK said...

Fantastic post Dave, as ever!! I can't emphasise enough the point made by a commenter above, you simply must write when you give up the paraffin budgies for the pool and the adopted cat.
Today I was taking a 747-400 from Lisbon to Madeira's infamous perched-on-a-cliff-edge Funchal airport on a familiarisation run. An hour out of Portugal, out FL300 for 1400ft as per the STAR, soon running into thick cloud with a very low base. Approaching the FAF still in-cloud and with no option of a precision approach, I dial in the alternate - Tenerife - into the FMC - still blind to the looming cliffs outside and *crash*.
Flight Simulator falls over and I'm back at my desktop.
You've no idea how envious I am of you doing this stuff for real - ice or no ice :)
Starting my PPL in the next few weeks. Your blog makes it almost unbearable to wait until that little C150 is mine!! :)
Take care Captain Dave, my best to the cat.

Really cool reading in our hot Australian summer. I never tire of reading and re-reading these posts...

Tim G in MN said...

Jay,
Maybe I took the "We want you to try" comment a little too literally based on Dave's choice of words: "I will be more than happy to try to get airborne", (I know that Dave or any other professional pilot would not attempt to take off if there was any question whether the aircraft would actually fly.) I DO think that all too often flight crews are put in the no-win position of making go-nogo decisions with pressure from the company and angry travelers competing against common sense and instinct. And then they get their pay cut...

Hey Dave! Was that you landing on Rwy 35 at KMSP at about 1:25pm Saturday 3/7? I waved from the top of the parking ramp at MOA.

Raniero said...

Sorry Dave, may I ask you a question?
Why did you use your cellphone?
Maybe you were trying to hide the refusal you were going to receive (radio communications are recorded, so in case of any weather problem the airline could have been proved guilt)?

There was another bird strike flying out of Phoenix last Wed. night - Mar.11 - what happened?

Thanks for your great posts Dave Absolutely Fabulous!
Take great care.

you've been a great pilot Dave!And as well as a great writer. Keep it up.

Robin Wendell said...

Wowee. Nice job, nice post. Thought of you coming home from NYC on Friday. I looked down the aisle at take off to see the flight deck to see the door OPEN. Yipes! It was really cool to see the take off that way. The F-attendant tried to close it after a while but it kept springing open. They finally got it closed 10+ minutes into the flight. I don't think anyone noticed except me... joked w/the captain when debarking.

BYW thanks for turning me on to Anne's blog, I'm enjoying her posts.

Sending {{{light}}} and steady wings.

Captain Dave,

To try to add to the compliments you have received on the high quality of your writing and the unique window you provide the layman into a special world would simply be superfluous. I like many before can only say ...thank you.

For those wishing to hear the pace at which Dave and ATC lives, I've recently found a great site, www.liveatc.net. From there you can listen as the pilots and controllers perform their magical ballet at airports around the world.

As an example, 3-16-09 at 4:15PM an American City MD-80 at 100' on short final to KBOS suffered a bird strike. The tower and UAL-536 landing right behind, reacted immediately, checking on the saftey of the AC flight as well as the prescence of other birds or debris. A quick thank you among all and it was back to pushing tin during the evening rush. Cool, calm, professionals all.

Jim Glendenning said...

CAPT Dave,
You are doing a great service for the profession here. Most people have no idea about the many and varied considerations that pass through a pilot's mind each and every minute of a flight. For most observers it appears as if the pilots are just sitting there and, except for manipulating the controls, gear, flaps, computer and radio tuning there isn't much going on. It's only when you share the mental decision processes and all that goes into them that the value of all the experience and training becomes apparent. As we used to say, "It's why we get paid the big bucks." At least some people are getting exposure to it through your blog.

here in Philippines we don't have storm i guess where very lucky but how i wish it will snow here. your a good captain Dave wish you more flight stories

Hi Dave,
"Interesting" take-off:))
Can you recall the actual windspeed and direction? I've got a session in an A330 FFS in the UK this coming weekend and would like to have a go at something similar. I know that a 330 is a little larger than a 320, but are the flight dynamics designed to be very similar, or is the similarity confined to the 320 series only?
Thanks in anticipation...
Kind regards,
