Learn something every day

At the bottom of the Nav Canada NOTAM query page is a box with red text that I’ve been curious about for as long as I can remember:

Note: Under certain conditions being familiar with this section only, before commencing a flight, doesn’t meet CAR 602.71 and AIM-RAC 3.3 requirements. Please review all NOTAM files above for complete information.

I have read through 602.71 and RAC3.3. They offer no clues as to what the “certain conditions” might be, so I’ve always just ignored that phraseology and pulled all the applicable NOTAM files, slowly picking and choosing my way between stuff I care about and stuff I don’t. But I remain curious about that language: this is aviation. Nothing is a part of any process Just Because. There had to be a reason.

The answer, it turns out, is available right here. And it’s my own damn fault for not reading the manual in the first place, because the explanation is actually quite obvious when you stop and think about it. The fact that I had never actually encountered the described phenomenon is a function more of luck, or circumstance.

Interesting, eh?

PIREP: Telex Stratus 30XT headset

Back in the spring, I bought a Telex Stratus 30XT aviation headset from these guys. Not because they’d been offering the world’s greatest price or anything, but because they had the best shipping plan I could find (to Hawaii). Owing to scheduling issues, it has only been in the past couple of weeks that I’ve actually manged to fly with it very much, and I can now report back on what it’s like. I offer this PIREP mostly because when I was shopping for the thing, I found very little by way of reviews to work off of — people seem to like talking about the Stratus 50D or the Bose X, or the Lightspeed Zulus; the mid-tier headsets seem to be neglected.

So: the headset. It is very comfortable — much more comfortable than the David Clarks I used to fly with, and more comfortable to my head than the Bose X that everyone else seems to like, though I admit I don`t have a lot of time with a Bose on my head. The clamping pressure is adjustable through a couple of cams on each earcup, and the seals are sufficiently padded to spread the pressure out over your skull. It can get hot: while doing crosswind landing practice in the middle of the summer, it was awfully sweaty under the headset. But the overlarge earcups make it tolerable.

Noise isolation is excellent. I’ve managed to forget to turn the noise cancelling on a couple of times now and it wasn’t until I was in the climb that I noticed the plane was a lot louder than normal. This is actually a good thing, in that you don’t have to carry a charging cable and/or spare batteries if you’re willing to “tolerate” some time in the air with “only” 26dB of noise reduction. You probably learned to fly with less noise reduction, so I can’t think this is going to be a deal-breaker for anyone. Turn the ANC on and discover that it is, in fact, a lot quieter in the cabin. I don’t have numbers readily to hand, but it’s more than quiet enough to help combat some of the fatigue.

The sound quality is excellent. I’ve piped my iPod directly into the headset and it sounds as good as my Audio-Technica headphones. Yeah, I know it’s an iPod, but it’s good enough. Whatever readability problems I’ve had so far have been aircraft-specific; in our fleet there are a few planes that have wonky intercoms or balky radios built by people wielding rocks, but with a good avionics panel it sounds great. With bad avionics it sounds OK (the plane I’m thinking about in particular is damn near intolerable with passive David Clarks).

The phone adapter works. I know because I’ve been using it as my hands-free device at home (yes, I am a loser, there’s no need to send e-mail on this) when waiting on hold with call centers and such. I have not been able to get it to work with my iPhone, because the iPhone uses a 3.5mm TRS connector and the Stratus takes a 2.5mm. I need a wiring diagram to get the appropriate cable (though I think a straight four-ring 2.5 to 3.5 would do the trick), and I’ve been too lazy to do that so far, though I probably should since it’s cheaper than buying a handheld radio and the light gun is hard to see at CYYJ.

The microphone’s windscreen stays on. The boom stays where you put it. It does an acceptable job at dealing with the wind noise when the eyeball vents are open and blasting straight at you (an issue when flying in the middle of summer). Sound quality (for other people) is great; people say I sound perfectly normal, and I guess that’s a good thing.

So there you have it: $500-ish for a reasonably good-quality noise cancelling headset. Not as flashy as a Bose, but also not as expensive. Recommended.

Edit: As I was shutting down from today’s adventures in the air I was reminded of the one minor nit I have with this headset — Telex ships a set of Energizer rechargeable batteries in the box. These are shit batteries, especially if you’re not flying every day; the self-discharge rate is atrocious (like, they last about two weeks flying 4-ish hours in that interval). I’m probably going to replace them with NiMH Eneloops, but I’m not sure how the charging circuitry will hold up. Anyway, just be aware this is a bit of a problem if you don’t feel like plugging your headset in every couple of weeks.

Utilization update

I somehow missed this when it got posted last month, but for future reference, on the subject of Air Canada’s aircraft utilization for the W11 schedule:

AC is leasing two ex-HA 763s, one enters service on YYZ-DUB next week, the other does not arrive till the fall. These are fin 691/692. Fin 691 will fly YYZ-DUB with a slightly modified HA interior this summer.

The current plan is for these aircraft to replace two of the non-XM 763s (fins 689/690). Also in the plan for these aircraft is an interior upgrade in the Fall – which should include seatback TV and a North America Executive Class seat – no lie-flat suites. Note that I say “should” for the seatback TV – this is not yet 100% confirmed due to time constraints.

For the winter, fins 691/692 are presently scheduled to operate: YYC-OGG, YYC-HNL, YVR-OGG. Fin 687 will operate the Air Canada Vacations flying from the west (MBJ, CUN, VRA etc).

YVR-HNL is schedule to operate with the XM lie-flat product, though, this could change on certain days of week.

This is some of the best news I’ve heard about those airplanes in eons. Yes! Move off of routes I don’t actually fly! (Shame they’re getting rid of 689, though, and holding on to 687 — 689 is/was HPF, and as nice a non-upgraded airplane as you could want. 687 is HPD, which has stupid 1.5″ protrusions into an already narrow seat for the IFE controls, and is damned uncomfortable.)

Picture time

I am, as the Twitter feed has suggested for a couple of days, back from Japan. (Some of you had no idea I was even over there! Which lead to one of the funniest Foursquare checkins I’ve ever had!) A fuller, more detailed trip report will follow soon — I promise — but I have put some photo galleries up for your perusal and enjoyment:

Please enjoy!

That’s one hell of a terminal change

I’m in the process of hunting for a cheap way to get 2,080 miles on some combination of Star Alliance carriers before the end of the year, having fallen short of the magical requalification threshold by that much. (This is much worse than last year, where I was 84 miles shy, which required a one-way flight from Vancouver to fix.) It’s just enough miles that a quick trip to Alberta isn’t really feasable without some creative routings, and if I’m going to do something creative I might as well have some fun with it. Also, I’d like to keep the number of days on the road down as much as possible, which means doing a same-day turn if I can pull it off.

Also, we’re doing this in November or December. And I’ve had quite enough fun being stuck somewhere because of environmental problems this year, thank you very much. So: western and midwestern spots affected by snow are a bad idea. East coast spots affected by hurricaines and storms are also a bad idea. Practically speaking, for Star’s hub route structure across North America, this means: no Toronto, no Montreal, no Chicago, no Philadelphia, no Denver, no Newark (well, Newark should never be on that list anyway). This refusal to accept the major eastern hubs pretty much deletes the southeast as a potential mileage run destination. I’m not in the mood to do a trans-Pacific, and as I say, I only need 2,080 miles, so there isn’t much point in spending more time than absolutely necessary to accomplish my goal(s).

Considering the limitations, it pretty much comes down to Texas, Nevada, California, and Arizona. Enter the ITA Matrix. They have a new version of the tool (you can find it on the right), but I much prefer the older, less-slick interface. If you dig around a bit, you eventually discover the route query language, which — when combined with the month-long view — makes for one hell of a useful method of finding the right combination of cheap destinations when you don’t actually care where you end up.

I’ve learned a few interesting things using ITA this past week. One very interesting thing is that getting to San Diego from Victoria is unreasonably difficult, even if you’re willing to expand to non-Star Alliance carriers. Another is that, despite direct service from Vancouver to Houston (on Continental) and Dallas (on American), getting to Texas isn’t cheap. (Though having said that, if I needed to be in, say, East Texas and didn’t care about alliances or miles, I could fly through Seattle and go direct to Austin on AS. This… does not help me.)

A third thing is that you need to be very careful when agreeing to change terminals, because ITA has a very loose definition of what a terminal change means. It’s one thing to be willing to fly into, for instance, MCO and out of TPA — they’re theoretically in the same city (for varying definitions of the concept of “city”). It’s quite surprising, on the other hand, to look at a proposed itinerary and discover that your change of terminal involves going to a different state — fly into LAS, leave from LAX.

I bet if you weren’t really paying close attention, that might seem quite reasonable.

As for what I’m going to do? Probably YYJ-YVR-LAS and return, or something like that, on a same-day turn. If I can find it for cheap on the weekend (hah!), K. and I might make a quick trip out of it (I am still getting silly offers from the Wynn, and I’m told rooms in Las Vegas are wicked cheap right now) — just so this isn’t a pointless expenditure of money solely for the sake of flying around. But I’m also considering YYJ-YVR-SFO, with enough time in San Francisco to get down to the waterfront, have a Manhattan and the hangtown fry at Tadich, and back out to the airport again. That’s a good reason to get on a plane, right?

Paul Harvey time

Everyone has seen the video of the Cebu Pacific flight attendants dancing their way through a pre-takeoff briefing. It turns out there’s more to the story than has been initially reported. The executive summary is that it was done in cruise as part of a test project to gauge customer reactions (after having done a more traditional briefing before departure). CEB is apparently happy with the response.

No word on whether future flights will include trials with other modern pop horrors.

The stupid burns

AvWeb: 100 Years Later, Where Are The Women Pilots? Also known as, “The Lack of Women in Aviation, as Debated and Explained Primarily By Men”:

It has now been 100 years since the first woman earned her pilot license. So, why are we still celebrating women pilots’ firsts?
Could it be our sheer numbers, or rather lack thereof? When Raymonde de Laroche earned her pilot license in 1910, number 36, she represented about three percent of the pilot population at that time. One hundred years later, women still only constitute about 6% of the pilot population in most western countries. With so few women pilots, it is not difficult to understand why firsts are still being made. But why are there so few women flying?

Mireille Goyer is perfectly capable of defending her own arguments, and advancing her own positions, so I’ll leave it to her to offer an explanation for why women aren’t well-represented in aviation. She picks out a fairly superficial example — the uniform of flight crew at an airline — and runs with it, in what I suspect was probably an attempt to illustrate the cultural dynamics at work and the problems facing women who aspire to a career in aviation. It is thought-provoking stuff: is your aviation workplace a friendly environment for women? If you’re a man, how do you know? What does it look like from a woman’s perspective? Are you doing everything you can to make sure that women (and minorities) are welcome? If not, what do we do differently?

Ms. Goyer doesn’t come out and say it in her article, but the post linked above does posit an explanation for why there are so few women in aviation. Go read the comments! (In this case, I mean it.) I mean, in a field where people say things like “can any of you name one – just ONE – discipline which has been upgraded, improved or created any new interest in it – by virtue of women being involved in it? The answer is a simple…NO!” — gosh, why, a woman would have to be crazy to think about not getting involved in the field! Amirite?! I mean, clearly the problem is that women are just ______, not that men involved in aviation on a day-to-day basis are knuckleheads or anything like that. Or that there might be serious structural impediments to prevent women from getting into a flying career. Anything but that.

Touch and Go, added later: Probably the most unsurprising thing about the whole article/comment thread (as you can probably see from a brief glance at it) is that you have women, on the one hand, who say, “There’s a problem here” and men who say “No, there isn’t.” The display of privilege here is truly staggering — it’s breathtaking in its completeness. This is why there aren’t more women in aviation. This, right here.

(This is also an awesome example of what privilege looks like on a daily basis; it’s not all name calling and back-of-the-bus seating. This is a bunch of guys who have never once had to consider whether other people thought it was right for them to be pilots, who have never had to consider their own built-in biases and their own structural advantages, and who’ve never ever thought about what their “inclusive” world looks like to someone from the outside. Turns out it’s not so inclusive now, is it? I sound disappointed, and maybe I am, but I guess it’s going as well as the open source adventures in equality. So maybe there’s hope.)

I posted a few comments and got a few replies; some of the more odious sentiments expressed included disbelief or uncertainty as to why we’d want more women flying in the first place — a statement so arrogantly sexist as to defy understanding. Nevertheless, dude AvWeb readers are apparently happy with the current configuration of aviation, have no problem with the size of the existing pilot pool (maybe they’re disgruntled renters who don’t want more people flying for lack of aircraft availability, or are worried that getting that airline job is going to be that much more difficult), and don’t see any need to change. That’s their right, of course, but they should at least be honest about what they’re doing: restricting access to aviation.

And even further (1500 PDT): First, Twitter tells me there have been a few readers who’ve wanted to leave comments, but couldn’t; sorry about that. I’ve fiddled with the settings and it should work now.

Second, I finally came up with an analogy about privilege that might make sense to pilots; it’s the post in the AvWeb thread about turbulence and ignoring your passengers. Note to self: write post about “pilot’s privilege.”

Third, to clarify my comment about “restricting access to aviation” — my understanding is that we want to grow aviation, and that we want to ensure that we continue to grow as an industry. Adding people passionate about flying is only ever a good thing. If we refuse to work to create an environment where all feel welcome, regardless of gender/gender identity, sexual orientation, ethnic background, or religious creed, we are deliberately excluding specific segments of the potential pilot population from participating. Some will suck it up and soldier on. My greater point is that they shouldn’t have to suck it up — so that the folks who don’t want to bite their tongues feel able to participate, too.

That exclusion is not a goal. But it is the unintended consequence of failing to be as inclusive as possible; indeed, this is the major problem with systemic discrimination — it’s never the intent to be discriminatory. Fix this, and we have a better chance at surviving the next 20-some years as more people learn how to fly, spend money on flying, and become passionate supporters and political defenders of flying. Leave things as they are, and in 20 years GA will probably look a lot like it does now — just a lot smaller.

The other problem with simulators

Paul Bertorelli has a new post up about the limits of simulation training, specifically as it relates to crosswind handling characteristics. The comment thread following is unusually good. I’ve never flown a motion-base simulator before, nor do I have any experience behind or in front of turbine engines or transport-category aircraft where simulator-based training formed a major component of the education, so this is a topic to which I can add very little. I would, however, point out one of my very favorite items from an issue of the Aviation Safety Letter last year: a letter talking about the limits of the simulator as a method for dealing with in-flight fires.

“Smoke in the cockpit after departure hopefully initiates a checklist routine, but only at the end of the procedure does the option of returning to the airport come into play, if at all. “Okay, that’s done, let’s carry on,” is the lesson actually learned in the training and carried forward into the flight test. Survival is only a secondary consideration,” as the letter-writer puts it. He goes on to point at SWR111 as an example of what happens when pilots fail to recognize that they’re on fire and they need to be on the ground now — a habit that seems like it would only be developed through the use of simulations. In fairness, I’m not sure how to educate pilots in this, short of lighting the plane on fire and saying, “Good luck!” So maybe there’s no other way to get around that problem.

As I said, I obviously know nothing about transport simulator training curriculum, so I can’t really speak to how it works in the real world. But when you set up a fire, and then run the fire checklist — do you then turn around and fly the plane to the ground? Do you simulate the evacuation? (CKT28M, anyone?) Could you come up with a way to realistically simulate the incapacitating effects of cockpit smoke? (Fail the flight instruments and then blow the external displays?) If we don’t do this, why don’t we do this? As we train, so shall we fight — or something like that, anyway.
