Turbulent

We're in the sky over a major Canadian city and my dispatcher has had to pull favours and whine to get us here. We sent subcontractors to do this job, because we're very busy, but they were denied entry to the airspace. Apparently we're the A Team, because ATC let us in. Company has given us a list of other work to do for when the controllers have had enough and kick us out of their airspace, but meanwhile the controller has cleared us in and given us a pretty free rein, as long as we remain west of his runway in use. Accordingly, I'm on my best behaviour, staying super alert to what the controller is doing and giving him the information he needs in the clearest most concise words I can find. He has been amazing, routing traffic under over and around me so that I can do my job, and even keeping track of where we were working when he has to divert us.

It's turbulent, continuous chop from both convective heating and mechanical turbulence. I think I'd be feeling sick if I weren't flying the airplane. As a pilot I want to help my co-worker feel better, but all the normal advice and techniques one would use to mitigate airsickness don't apply here. It's his job to have his head down concentrating on computer screens, and it's mine to make frequent quick turns and altitude changes. He does his job and I do mine and we continue that for five hours, finishing the high priority job and then thanking the controller profusely before we switch en route to land at a satellite airport outside their airspace.

I'm usually kind of slow getting out of the cockpit after a flight, but today I jump out and get water for my co-worker and start fuelling the airplane. I'm compensating for not being able to help during the flight.

I get in to taxi to parking, and he gets in too. "Coming for a ride?" Yeah, a long ride. Company has texted him instructions for further work we are assigned to do. He gets right back in the airplane and we taxi out. There's a Cessna in the circuit, and only one taxiway with a backtrack, so we wait for him to land and taxi clear. Someone else has called meanwhile with an intention to cross midfield and join the circuit, so we enter as soon as the Cessna is clear to make the backtrack and take off before the other airplane arrives. And then the arriving pilot almost instantly calls base. That was unexpectedly quick. I guess he changed his mind about crossing midfield. He changes it back when he realizes I'm on the runway, and I'm rolling while he's on final.

More on this flight later, I think.

Not Supposed to Say

I'm flying from point A to point B, and remarkably neither A nor B is named after an animal or a body of water. I'm not on a flight plan just "VFR company note" which means my company is in charge of reporting me missing if I don't turn up, and I have flight following which means I'm monitoring the frequency of a centre controller who occasionally looks at my blip on a radar screen and, time permitting, tells me if any other radar blips threaten mine. Presumably if my radar blip disappeared and I stopped talking to them they'd tell someone or make a note, too. At the very least, if I didn't turn up at destination and company reported me missing, they could examine the records (still called "pulling the tapes" as if they were recorded on tapes sitting on a shelf) and see where my blip was and whom I was talking to when I was last recorded as existing. As I cover ground, the controller whose frequency I am monitoring will eventually say, "Switch to my frequency 133.40," or "Contact such-and-such Centre now on 122.75." The same controller may be monitoring different frequencies and she moves me to the one with the best reception for where I am, or I'm moving out of her area and she is passing me on to the next sector. My information moves with me to the new sector so I just have to say my call sign and verify my altitude. They already know where I am going, but they verify it, because there are multiple airports in the same city. Another airplane checks in on the frequency. The controller gives him the altimeter setting and then it's quiet again. My headset detects silence, so lets the MP3 player sound into the earphones. (Currently playing Convoy, featuring another profession with radio jargon). The new check in comments on this, "Kinda quiet today." The controller agrees. "Getting the crossword done?" asks the pilot. "I'm not supposed to say," replies the controller, which was way more hilarious in the airplane than it seems right now. It was the way he said it, like he was really hiding some big secret. The controller passes me on to the next sector and I say to my coworker, "I should have asked him if he had figured out twenty-one across yet."

Your Route Is Clear

This incident occurred the day I realized that I perhaps I should start blogging some of my adventures again. It was just such an Aviatrix day. Over ten hours logged, and once upon a time I would have had a sheet of paper under my operational flight plan on my lapboard and filled it with cryptic notes that would allow me to recreate the whole day for you, but a girl has to sleep and do her company paperwork sometime, so here's just that slice, complete with its life lesson.

We were assigned to work in military airspace, and I had been given a sheaf of papers including maps, the names, telephone numbers and e-mail addresses of what seemed like half the chain of command and their administrative assistants, plus instructions that we did not need to telephone anyone, just call RADIO CONTROL on such-and-such a VHF frequency ten minutes out. "Radio control" is an odd way to address an ATC entity, so I looked up the military installation in question in the CFS (directory of all Canadian airports) and found that the frequency was that listed for the local tower. Now that made sense. I called them up as instructed, with a proper efficient position report and request, "Basename Tower, this is Aircraft Type Foxtrot Alfa Victor X-Ray, forty miles northwest, nine thousand fife hundred. Request entry to CYR for previously approved air work one zero tousand seven hundred." (Someone is now itching to point out that if I was going to be truly proper I would have said "niner" and maybe I should have, but Canadians usually just say nine. I would have remembered to say niner for an American base, I hope). The numbered CYR is the designated airspace controlled by the military base.

The response is something to the effect of, "Go ahead your PPR number." PPR is a common abbreviation for "prior permission required," but I don't remember seeing such a number in my sheaf of papers. I have a quick re-read and no, there isn't one. My fellow crewmember already has his cellphone out texting company and in barely more time than it took me to indicate to the controller that I would try to get that for him, the number is provided to me. It was "six". Okay it was 2012-0006, but essentially the number between me and the airspace in front of me was six. I provide it in turn to the controller and we breathe a sigh of relief when it acts like an unlocking code to the secret levels of the video game and he says, "Your route is clear."

That sounds like permission, but it's not standard civilian phraseology, and I want to be absolutely sure. I'm organizing words in my head for the clearest, most succinct and professional way to say, "I am a civilian pilot unversed in military ATC differences, please confirm that means we are cleared as requested," when he buries that slightly fuzzy phrase in a question containing a pile of acronyms and numbers so deep that I don't know where to start asking. I think the best I can come up with is, "I'm sorry, I don't know what that means." I've been through military control zones across North America and while there are usually some quirks, I've never been at such a communications impasse before. Eventually I figure out that he is asking about the exact location of the work relative to the trans Canada highway. Yeah, one of the numbers turned out to be the local designation for Highway One and I think the rest were terms relating to the land covered by the restricted airspace. He stopped using them. We go back and forth a bit on this. He says "over" or "out" after every transmission, which is in fact part of the rules in aeronautical radio procedures, but in practice is only used when reception is terrible.

He's asked me to remain east of the highway, which is essentially an east-west highway. We don't seem to share enough common vocabulary or reference points to discuss this. He says "Wait out," which I presume to mean standby. He then comes back and asks me to fly a holding pattern. That's unexpected for a VFR aircraft. Usually a controller would just tell me to hold outside the zone, or give me specific holding instructions, but I can handle this. I'm five minutes from his airspace now, so I just fly a hold right there on the inbound track, working out that I need a one minute thirty-five second outbound leg and a fourteen degree outbound correction in order for a rate one turn to bring me perfectly back onto the inbound track, with six minutes showing to the destination. I call him back to ask for an estimate of how long I might have to do this for, but there's no answer. Eventually he comes back and tells me I'm cleared to work, "do not proceed east of [three digits spoken singly] dot one four." Now sitting where you are reading this, even with my obfuscation of my exact location, it's probably obvious to you that he was giving me a longitude, and I did figure that out after a second or so of staring stupidly out the window. It was just such an unexpected way to designate a meridian of longitude. I read it back as [three digits] degrees, fourteen minutes and told him that our our work straddled [meridian]°14'. We were at an impasse, so we lobbed the whole problem back to company to sort out on the phone and found some other work to do.

They called us back with an approval when we had not quite enough fuel to do the job, so we landed and refuelled and came back up to discover that "dot one four" meant decimal one four degrees, not fourteen minutes, so I had only to remain west of [meridian]°09', which I could do, and we quickly completed the job. It hadn't initially even crossed my mind that I'd be given a longitude in decimal degrees. Who navigates in decimal degrees?

Afterwards I lamented to my coworker the failure to communicate, and he was the one that came up with the realization that we were not talking to a military air traffic controller at all. We were talking to a comm tech down there on the ground with a radio, whose principle job was to keep people from blowing each other up on the range. When he said "out" he may have sometimes meant he was putting down the radio and walking away. And he probably had even less idea of what I was saying than I did of what he was saying. Because as the conversation got difficult I retreated to the most excruciatingly correct formal aviation radio language I could muster, trying to measure up for this terribly important military tower controller who didn't have time for anyone who didn't file flight plans in mach numbers, when really he might have been just as intimidated by my pilot jargon, causing him to try to duplicate it, and coming up with phrases that didn't mean what he thought. He hadn't once called himself "Basename Tower," just "Range Radio."

We had to return to that zone on another day and by changing my perception of the person I was speaking to, I changed my experience completely. I finished the mission by saying, "Thank you for your service," allowing him and others in earshot of the radio to perhaps realize that they had not really provided any air traffic control service to me, and that I was really thanking them for serving our country.

That made me wonder how often I have attributed to someone else too much authority or too much knowledge and, in trying to approach them at the level which I think they are expecting, have intimidated or alienated them. In future I will remember that the person in the metaphorical or physical intimidating tower is possibly not disdaining me at all, but in the same situation of trying to appear informed and in control. Maybe that would even work on the Springbank Tower controllers. And if someone is just being unnecessarily officious, they'll think they're being condescended to, which they deserve.

The Empire Will Be Pleased

The title is what my coworker said through his Darth Vader oxygen mask as we descended from the flight levels in an unpressurized airplane after completing a tricky piece of work. We descended overhead Banff, Alberta. It is so spectacularly beautiful there that I was distracted from the work I was supposed to be doing. I was even raving about the remarkable pointiness and ridginess and beauty of the scenery to the air traffic controller. The air traffic controller was meanwhile excited by the fact that I could still talk to him. We went from the flight levels to dodging in and out of those spectacular stripey peaks and we still had excellent two way radio communications. And then we landed at Springbank. Springbank is the Buttonville of Alberta. Screaming busy with training traffic, and controllers who tell you what you want instead of listening to what you requested. The best was the one who gave me an instruction to turn right, and then chewed me out for deviating from the straight out departure clearance I had been given. Such a startling contrast from the service I got from the very next controller they handed me off to. I cannot turn right and go straight at the same time, although with some of the aerial work I do it almost seems that way. If you have the opportunity, you should go to Banff and fly around at about 11,000' in the spring. I think you should put it on your bucket list. I'm a not a stranger to mountains, Banff just seems to have especially amazing ones.

Always Check NOTAMs -- Even When Running Drugs

Pilots and regular readers know that a NOTAM (NOtice To Air[wo]Men) is a little bulletin describing a change to facilities, airspace or procedures that isn't published on the current charts and publications. They look boring. They can be tedious and repetitive to read. Most of them won't pertain to your operation. If you fly out of some little flat bit of the wilderness airport there's probably a NOTAM about the airport lighting being unserviceable from shortly after the snow melts until whenever it is that gophers go back into hibernation.

You can look them up here for Canada if you know your airport identifier. They look like this.

That's less than half of the Halifax NOTAMs this afternoon. If you're really operating out of Halifax you need to read them all, plus all the ones for the place you are going, and the ones covering airspace you'll be passing through, and possible diversion airports. The float plane guys don't care about the GNSS approaches. The airlines don't care about the windfarms. No one on wheels cares about the change in the operator's telephone number for the Church Lake waterdrome, but they are filed by the order they were filed in, and no one has realized the safety benefit of somehow filtering or classifying them.

They're a fairly often neglected aspect of flight planning. If you're flying between familiar aerodromes on a regular basis, there's a strong temptation to skip them. The flight briefers don't give them unless you ask. (And I still haven't forgiven the briefer I asked for NOTAMs for a flight from Meadow Lake to Buffalo Narrows, who neglected to tell me that the airspace I was chartered to fly through was in use by the Canadian military and their international guests for fighter jet exercises. It's the only time I've called and asked to speak to the supervisor of someone paid to provide me with flight services.) I have fielded a phone call from an airborne coworker who sighted vehicles working in the vicinity of his destination runway, "Avi, could you please check and see if there's a NOTAM ..." (There was).

So I can see how if you were conducting an operation that wasn't actually legal in the first place, transporting certain agricultural products, for example, that you just might not bother to check them. But these folks would have had a better day had they done so. A US reader will probably clarify the difference, but the Americans do have what I'm going to term a special relative of the NOTAM called the TFR (Temporary Flight Restriction) which highlights what in Canada would be NOTAMs restricting airspace to certain operations. They probably did this because people were missing NOTAMs and ending up on the windshield of Air Force One, but what it probably does is make the problem worse, with people clicking on the fun little map that tells you where they don't want you flying today (hey, is President Obama in Seattle today?) and then figuring that covers the important stuff and not going through to the boring list of nav aid outages.

CAT I Takeoff

I'll tell you about the circular yurt construction shortly, but today I couldn't pass up this story about a cat that escaped from its carrier before take-off on an Air Canada flight. Air Canada allows small pets to be carried in the passenger cabin, provided that they remain in approved pet carriers that fit on the floor under a seat. The door to the carrier was, according to the passenger 'inadvertently opened' while the carrier was being stowed. My initial guess was that the passenger wanted to give Ripples a quick snuggle before shoving it under the seat, but apparently security video shows that the CATSA inspectors who opened the cage for security screening did not secure the latch. In any event Ripples saw an opportunity and fled.

So you have an airplane, which is not a really large place, and a cat, which is not a large animal and the other had to be found inside the one. That took them a while because the cat had done what cats do and found the smallest, warmest most inaccessible compartment in the whole aircraft: an avionics bay. This is the airplane equivalent of getting into the computer rack and curling up on top of the server. Or sleeping on top of an old-fashioned TV inside the entertainment unit. They had to access the avionics through an exterior panel to remove the cat and then to ensure that it wasn't a trained terrorist attack cat that had left a little explosive payload in there--or a non-terrorist cat that had simply chewed on something or left a payload of another variety--they took a further delay to inspect the avionics.

I thought Air Canada didn't carry pets in the winter months, but here's their pet policy. They accept them in the cabin, as checked luggage and as unaccompanied cargo. They do have seasonal restrictions on pets in the baggage compartment to keep pets from being baked or frozen during ground handling.

I stand by my earlier statement that there should be a program in place whereby a passenger wishing to have a cat at their destination registers the one they have, drops it off at the airport and on arrival is given one of a similar size and colour, to enjoy for the duration of their stay.

Solve for X

Today someone in an aviation workplace was either amused or insulted, I'm not sure which, by my excitement that he was genuinely using trigonometry for real things. I'm afraid that he may have thought that my excitement and admiration was over the fact that he knew how use trigonometry at all, but really this is just one cool part of a very cool project he is working on.

What do you think he's up to?
