Aviation’s Number One Rule

In my 40+ years of flying I have seen several aircraft accidents unfold while I watched.  A few turned out well and the aircraft occupants  (and occasionally the aircraft) were able to fly another day. Others turned out not so well.Aviation Rule #1: Fly The Aircraft!

Of the aircraft fatal accidents that I have seen, all appeared to have the same characteristic… the pilot violated the Number One Rule In Aviation: Fly The Aircraft.

This image is an excerpt from the top of every emergency checklist in every type of aircraft found at a major airline where I used to work. If professional pilots have that as the first step of every emergency, why don’t we as general aviation pilots? These five steps can work in any aircraft – if the plane you are flying doesn’t give you a warning bell, siren or clacker to wake you up to the situation that is no big deal. There is probably an equally loud (or louder) alarm going off in your head, raising your blood pressure and putting your sweat glands into overdrive.

The closer you are to the ground, the less important are the steps after number one. If you have an engine failure (full or partial) on takeoff or departure, nothing matters except rule number one. It makes no difference why the engine quit or whether you are at a towered airport, your only job is to fly the aircraft to as successful a landing as you can make. Twice I have seen engines fail completely on takeoff.  In both instances the accidents were fatal – taking a total of five lives. In one instance gliding straight ahead or turning ninety-degrees would have landed the aircraft in the water off a rocky coast rather than stalling nose-down into those rocks. Another could have made a ninety-degree turn to an intersecting runway, but the aircraft stalled and the wreckage landed next to the runway. They didn’t follow aviation’s number one rule.

All this came to mind on one of my recent Pacific crossings. We had just checked in with Anchorage Center as we crossed the Aleutian Island chain near Dutch Harbor. A B-747-400 with colors identifying it as belonging to an Asian airline had just passed beneath us  headed the same direction. (They cruise at .84-.86 Mach while we were at .82). When I switched to the Anchorage VHF frequency I heard a pilot speaking in broken English telling the controller that they were going to have to divert to Anchorage. The controller immediately cleared them direct to the Anchorage airport. Then we watched as the plane in front of us made a right turn. The controller asked the nature of the emergency requiring the diversion. The  pilot said that a fight had broken out between two of the passengers and there were injuries serious enough to require medical attention.  The controller kept asking more detailed questions. It was obvious that English was not this pilot’s primary language. I could picture the cockpit with flight attendants calling to relay the conditions in the cabin, the Captain trying to direct the divert, reprogram the FMS, determine their estimated landing weight and determining whether fuel dumping would be required and give the copilot the information he needed to then translate and transmit to the controller.  It came out that one of the passengers involved was U.S. military and the other was Korean. The Captain wanted military and civilian police to meet the aircraft as well as emergency medical personnel. The  controller tried to get more specific information and the copilot finally came back on the radio, obviously harried and frustrated and said – I will call you back later, we have to fly the airplane now…

When you have something unusual going on in or with the airplane you have to establish priorities. Your Number One Priority – ALWAYS is to FLY THE AIRPLANE.

…..and he calmly steps off his soap-box and heads for the airport to do the annual inspection on his plane….

(No, I didn’t hear the outcome of the diversion. The other plane was soon switched to a different frequency. I did hear the controllers broadcasting that fuel dumping was in progress.)

Airline Retirement – New Directions?

compass direction Those of you who frequent these pages have probably noticed that I haven’t been posting any new articles lately. I have several things going on right now, not the least of which is my airline retirement in the beginning of next year.

AroundThePattern has been an interesting experiment. I have ambled along writing articles when the mood struck me, passing along things that I have seen or done in my flying career. The traffic on the site indicated by Google Analytics has grown slowly but I don’t have a large following by any measurement. It appears that the majority of the visits are logged by robots either indexing the site, checking on the display ads or looking for a location for comment spam. I have had some spikes when I stumbled upon a popular post subject but few readers have commented on anything I have published. I will be the first to admit that I’m not the most social person on the planet nor have I been very consistent in my publishing of articles and I haven’t asked for questions or comments very often. I just assumed that if anybody was really interested they would post a comment. To date I have posted 125 articles and received 133 comments with roughly half of the comments being my replies to the commenter.

The question then becomes whether I want to continue with the site as it is, change its direction with a new design and re-purpose (still aviation-oriented) or close it down and move on to other things.

I’m still sorting things out. Back in 2008 an article was published on ProBlogger that addressed the question of when to stop blogging. I replied to the article when it was published. It’s time to revisit the decision process.

A Morning with Malcolm the Skycrane

I went out flying yesterday, just a short flight to help a friend confirm the indicated airspeed he was reading on his recently completed RV-6A. I stopped and refueled after the flight, taxied back to the hangar and pushed the plane back into it’s parking spot. Just as I finished a stranger walked into the hangar and introduced himself. His name is Guy Keilman. His brother flies for the same airline that I do and mentioned that if Guy ever got to Stead airport he should look me up – that I have a Swift based there. Guy saw me taxi the Swift back to my hangar and was nice enough to walk up and say hi.

Erickson's Sikorsky Skycrane named Malcolm Guy is currently one of the pilots flying the Erickson Skycrane that is assigned to the Stead fire-fighting base this year. I say currently because he is actually assigned to fly from one of Erickson’s bases in Greece this summer. They operate on a 3-week cycle of work and free time and  just arrived back in the U.S. for his break. He was enroute to his home in Northern California when he got a call that they really needed him as a crew member at Stead for a few days. It was just a lucky coincidence that we met yesterday. We talked in the hangar for a while and then he said he’d be happy to give me a tour of the Skycrane. I jumped at the chance. Of course, I had to call my wife and let her know. She has watched the Skycranes operate from Stead for years and has always been fascinated with their size and capabilities. When she heard about the tour opportunity she dropped everything, jumped into the car and headed for the airport. If you are a Twitter user, you may recognize her as @yaksierra .

To say that the Skycrane is big is  a bit of an understatement. It is almost 90 feet long and it’s main rotor has a span of 72 feet – that’s twice the wing span of a C-172/182 or Beechcraft Bonanza.  Erickson names each of it’s Skycranes. The most famous is “Elvis” which made an appearance at EAA’s AirVenture last year (This year the crowd there is seeing “Goliath”). The Stead Skycrane this year is named “Malcolm.” Skycrane water tank and pond snorkle.

This photo is of the fire-fighting water tank that is attached in the area normally taken up by the winch/sling apparatus. As you can see, the tank holds up to 2650 U.S. gallons of water. The actual amount that they carry is dependent upon their fuel load, the temperature and the density altitude (sound familiar?). The fitting you can see in the middle of the aft ‘7’ is a fill valve for a 70-gallon foam tank. The foam can be injected into the water tank enroute to the fire. The foam is a detergent-based surfactant that, in effect, makes the water wetter.  The gray area at the bottom of the tank is one of the full-length doors in the fully open position.  The long hose is the pond snorkel. It has an electro-hydraulic pump at the bottom end that can suck water into the tank from any water source that is at least 18″ deep – and fill the tank in as little as 45 seconds. The tank can also be equipped with a sea snorkel that can be used to scoop up water while the Skycrane maintains forward motion – this eliminates the water spray up into the rotors that occurs when the filling process is done from a hover. The tank can also be filled with fire retardant very similar to that used by the fixed-wing tankers.  A control panel on the center console in the cockpit is used to set the amount and rate that the water is dumped.

There is also a water cannon that can be fitted to the left front of the Skycrane. It is capable of shooting a water stream up to 160′ to the front at a rate of 300 gallons/minute. It could be used to fight a fire in a high-rise building. You can see it demonstrated on the Erickson web site.

Skycrane Rear-facing Pilot Seat. This photo shows the rearward-facing pilot seat. The crew complement for fire-fighting is two pilots, however when the mission is heavy-lift construction (placing large items on construction pads or erecting tall towers) a third pilot is added to the crew. This third pilot sits at a station to the rear and below the main pilots. There is a clear view from there of the load suspended from the hoist/winch. When the load is to be placed into position this rear-facing pilot takes control of the Skycrane and can position the load exactly where it needs to go.

Sikorsky Skycrane cockpit. The Erickson fire fighting operation is day, VFR only which is reflected in the relatively sparse instrument panel that you find in the cockpit. Here you can see the control sticks (cyclic) at both seats and the collective for the right seat. One of those switches you see on the collective controls the pump at the end of the snorkel. The amount of water in the tank is indicated on a digital display in the top center of the left instrument panel. Right side windshield of Skycrane fire bomber. The center console is home to a lone Garmin 500 navigator and the VHF and FM radios. The FM communications band is used to talk with the fire fighters on the ground.  The right seat pilot on this crew used an ingenious method to keep track of all the information they needed when they were last dispatched to a fire. The bottom right block has all the Stead frequencies.

For those of you who subscribe to the idea that a helicopter is 10,000 parts flying in loose formation in an oil slick. Here is a photo of a large number of those parts – the main rotor mast head and transmission housing. Skycrane Main Rotor Mast and Transmission. The bell housing in the bottom is where the rotating turbine shaft of the right engine is changed to the other-direction rotating, flapping, twisting, retreating and advancing motion it takes to keep a helicopter in the air. I am not a helicopter pilot but if I were that would still look terribly complicated to me.  Maybe some of you helicopter pilots out there can make sense of all those moving parts.
