A Delta Pilot's Japan Earthquake Story

Diverted aircraft parked at Yokota Air Base

Disclosure:  I didn't write this story but offer thanks to the Delta Pilot who shared his experience.

I'm currently still in one piece, writing from my room in the Narita crew hotel.
It's 8am. This is my inaugural trans-pacific trip as a brand new, recently checked out, international 767 Captain and it has been interesting, to say the least, so far. I've crossed the Atlantic three times so far so the ocean crossing procedures were familiar.

Everything was going fine until 100 miles out from Tokyo and in the descent for arrival. The first indication of any trouble was that Japan air traffic control started putting everyone into holding patterns. At first we thought it was usual congestion on arrival. Then we got a company data link message advising about the earthquake, followed by another stating Narita airport was temporarily closed for inspection and expected to open shortly (the company is always so positive).

From our perspective things were obviously looking a little different. The Japanese controller's anxiety level seemed quite high and he said expect "indefinite" holding time. No one would commit to a time frame on that so I got my copilot and relief pilot busy looking at divert stations and our fuel situation, which, after an ocean crossing is typically low.

It wasn't long, maybe ten minutes, before the first pilots started requesting diversions to other airports. Air Canada, American, United, etc. all reporting minimal fuel situations. I still had enough fuel for 1.5 to 2.0 hours of holding. Needless to say, the diverts started complicating the situation.

Japan air traffic control then announced Narita was closed indefinitely due to damage. Planes immediately started requesting arrivals into Haneada, near Tokyo, a half dozen JAL and western planes got clearance in that direction but then ATC announced Haenada had just closed. Uh oh! Now instead of just holding, we all had to start looking at more distant alternatives like Osaka, or Nagoya.

One bad thing about a large airliner is that you can't just be-pop into any little airport. We generally need lots of runway. With more planes piling in from both east and west, all needing a place to land and several now fuel critical ATC was getting over-whelmed. In the scramble, and without waiting for my fuel to get critical, I got my flight a clearance to head for Nagoya, fuel situation still okay. So far so good. A few minutes into heading that way, I was "ordered" by ATC to reverse course. Nagoya was saturated with traffic and unable to handle more planes (read- airport full). Ditto for Osaka.

With that statement, my situation went instantly from fuel okay, to fuel minimal considering we might have to divert a much farther distance. Multiply my situation by a dozen other aircraft all in the same boat, all making requests, demands and threats to ATC for clearances somewhere. Air Canada and then someone else went to "emergency" fuel situation. Planes started to heading for air force bases. The nearest to Tokyo was Yokoda AFB. I threw my hat in the ring for that initially. The answer - Yokoda closed! No more space.

Sendai Airport Tsunami Damage
By now it was a three ring circus in the cockpit, my copilot on the radios, me flying and making decisions and the relief copilot buried in the air charts trying to figure out where to go that was within range while data link messages were flying back and forth between us and company dispatch in Atlanta. I picked Misawa AFB at the north end of Honshu Island. We could get there with minimal fuel remaining. ATC was happy to get rid of us so we cleared out of the maelstrom of the Tokyo region. We heard ATC try to send planes toward Sendai, a small regional airport on the coast which was later the one I think that got flooded by a tsunami.

Atlanta dispatch then sent us a message asking if we could continue to Chitose airport on the Island of Hokkaido, north of Honshu. Other Delta planes were heading that way. More scrambling in the cockpit - check weather, check charts, check fuel, okay. We could still make it and not be going into a fuel critical situation ... if we had no other fuel delays. As we approached Misawa we got clearance to continue to Chitose. Critical decision thought process. Let's see - trying to help company - plane overflies perfectly good divert airport for one farther away...wonder how that will look in the safety report, if anything goes wrong.

Suddenly ATC comes up and gives us a vector to a fix well short of Chitose and tells us to standby for holding instructions. Nightmare realized. Situation rapidly deteriorating. After initially holding near Tokyo, starting a divert to Nagoya, reversing course back to Tokyo then to re-diverting north toward Misawa, all that happy fuel reserve that I had was vaporizing fast. My subsequent conversation, paraphrased of course...., went something like this:

"Sapparo Control - Delta XX requesting immediate clearance direct to Chitose, minimum fuel, unable hold."

"Negative Ghost-Rider, the Pattern is full" (every aviation story needs a top gun quote)

"Sapparo Control - make that - Delta XX declaring emergency, low fuel, proceeding direct Chitose"

"Roger Delta XX, understood, you are cleared direct to Chitose, contact Chitose approach....etc...."

Enough was enough, I had decided to preempt actually running critically low on fuel while in another indefinite holding pattern, especially after bypassing Misawa

As it was - we landed Chitose, safe, with at least 30 minutes of fuel remaining before reaching a "true" fuel emergency situation. That's always a good feeling, being safe. They taxied us off to some remote parking area where we shut down and watched a half dozen or more other airplanes come streaming in. In the end, Delta had two 747s, my 767 and another 767 and a 777 all on the ramp at Chitose.  We saw two American airlines planes, a United and two Air Canada as well. Not to mention several extra Al Nippon and Japan Air Lines planes.

Post-script - 9 hours later, Japan air lines finally got around to getting a boarding ladder to the plane where we were able to get off and clear customs. - that however, is another interesting story.

By the way - while writing this - I have felt four additional tremors that shook the hotel slightly - all in 45 minutes.

Cheers,

J.D.

Tampa Thunderstorms


I just finished a long four day trip, emphasis on long. Four days, in my opinion, is just one day too many. We laid over in Seattle, Tampa and Puerta Vallarta, which made the trip a little more bearable, but it was still too long. Tampa was a mess…

When we departed Dallas, Tampa was being impacted by the leading edge of a severe line of thunderstorms that were forecast to be long gone by the time we arrived near midnight, but our first contact with Jacksonville Center yielded a holding clearance. The storms were moving much slower than predicted and filling in behind the leading edge. We had about 30 minutes of holding fuel and JAX as an alternate when we entered a holding pattern about 80 miles north of Tampa. However, as we neared our bingo fuel* we were informed that all personnel had gone home for the night at JAX. MCO was suggested, but was quickly ruled out since there were storms nearing the airport. FLL, MIA and RSW were all unacceptable for the same reasons. We didn’t have enough fuel to go any farther, so we had to stick with JAX as our alternate. Hopefully dispatch could get someone out of bed to service us once we landed. Just as we were about to make the decision to divert, we were given the option to be the first aircraft to attempt landing at TPA.

Tough decision. When fog or low ceilings result in a divert, you can fly directly to your alternate and land, often with little or no delay and the computed fuel needed to divert is typically accurate. When thunderstorms are involved everything is different and far more complicated. We turned toward Tampa with a lot on our minds.

Our first thought was that we needed to get down. We had been holding at 35,000 ft. to conserve fuel, and we were only 80 miles from the airport with a clearance to proceed directly to the field when able. There was conflicting traffic that made getting down difficult, but since the airport was landing to the north, we would have some extra time. Second thought was the line of thunderstorms sitting about 10 miles north of the airport. There was a small break in the line just northwest of the field through which a departure had just flown with little complaint, so we headed for the hole. Our ride through this area was unusually smooth, all things considered, but the lighting was intense. I have flown around many thunderstorms in my career, but have never experienced lightning like this. Most aircraft are equipped with a thunderstorm light in the cockpit that lights up the instrument panel with bright light at night to protect the pilots from being temporarily blinded by lightning. I had never used this light until tonight.

We continued our descent and picked our way around the storms until eventually turning final for runway 36L at Tampa. We were instructed to intercept the localizer for 36L, but were not given an approach clearance. There was another airline taking off opposite direction on our runway, so our descent would be delayed. As we continued on the localizer, the glide slope began to move and continued almost full deflection before we received an approach clearance. You must be careful in this situation, since you will have to descend at a greater rate than normal in order to intercept the glide path. My airline requires me to be fully configured for the landing, on speed and on glide path with engines spooled up by 1000 ft. above touchdown. Beginning the descent late makes this difficult. We started down at about 1500 ft/min to intercept the glide slope, began configuring early and met the 1000ft restriction just in time. The missed approach corridor looked pretty scary, but there was a small area of escape if we needed to use it. Hopefully we would not.

From about 800 ft. down, the ride was pretty rough, with gains and losses of about 10 knots all the way down. The runway came into view at about 500 ft. though light rain and the wipers noisily bouncing back and forth. I touched down deliberately as the Captain announced ”deployed,” referring to the speed brakes. As I put the nose on the ground my windshield wiper quit working…nice timing. The auto brakes worked their magic and the anti-skid cycled as we slowed. We cleared the runway and began our after landing checklist as another airline broke out of the clouds on final. We were one of only three landings during that little break in the weather. The others would have a much longer night. Shortly after we arrived at the gate, the storms again began to impact the airport. We earned our pay that night. I remember feeling rather accomplished and proud of our performance.


*Bing Fuel - As you enter holding, you must figure the amount of fuel needed to leave the pattern and safely arrive at your destination, execute a missed approach and proceed to your alternate. Decide on a “bingo” fuel early and stick to your numbers. Stretching your fuel supply is never a good idea. Remember…it is better to be on the ground wishing you were in the air than in the air wishing you were on the ground.
