As you may have noticed from reading this stuff, I like words. I
like to read them, I like to write them, I certainly like to say them! I like
to play with language, I like to mess around with words, and I like to explore
the impact of phraseology. I’m intrigued how by how you can completely change
the intent behind a phrase by subtly changing a word or two. I have no qualifications in this subject,
unlike my friend C whose first degree is in semiotics*. I guess I’m merely an
interested amateur!
I like the clarity of well written instructions. At work people
will write instructions for people to follow and give them to me first, to pick
the holes in, to find the flaws, the ambiguities, the loop holes. I like this.
I have a reasonable success rate, although I still stand behind the maxim “when
designing a foolproof system, never underestimate the ingenuity of fools!”
In a bizarre way I think this is why I generally don’t mind the
radio work and speaking to ATC**. Unlike speaking on the phone, which I hate.
On the radio everyone has a very limited bank of very specific phrases that
they use. The point is there should be no ambiguity at all. Contrast this, for
example, to phoning flight services. I hate this, the call is unpredictable,
they might be chatty, they might be hard to understand, they may be off topic. You
may have to struggle to find a common reference point. It’s an unknown. I
loathe it, I will actively avoid doing it if I can***
You may ask yourself, where is this going? Well there are a couple of
communication points I’ve come across recently that have struck a chord with me.
The first is my ongoing battle with the weather. Thanks to Bob’s minor bullying
whereby every lesson he makes me stand in front of the computer and decode the raw METAR and TAF
data out loud to him (to stop me hitting the decode button and “cheating”) I
can now read them reasonably well. Occasionally I still have to look up the odd
code or remark. Which got me thinking, why should I have to do that? It’s 2013.
Even the smallest airfield I’ve been to has access to at least one computer
with more processing power than was required to launch a mission to the moon.
Hell, even my cellphone can decode METARS quicker than I can. Why, in an area
where precision is important, are we still relying on (fallible) humans to
decode something that looks like this?****

When a paragraph roughly the same size as the one above will give
you all the same information but in plain English. With less chance of
interpretation errors.
The second thought that occurred to me language-wise was what
happens when ATC need you to overshoot for whatever reason. This happened to me
last flight. Due to traffic still being on the runway when I was on short
final, I was issued the following instruction “Juliet Papa Mike. Pull up and go
around.”
This is perfect, textbook phraseology. Except it’s not what you
should do.
If you “pull up” when attempting to overshoot, the chances of you becoming
a smoking crater in the ground are quite high. Let’s think about this for a
moment. You are on final; you probably have 20 degrees of flaps down at least
and are flying at roughly 65knots. You pull the nose up. Your angle of attack
increases, your airspeed decreases. You stall. You’re probably at less than 500
feet. You crash. Plain and simple.
What you actually do is apply full power immediately, without
hesitation. Then you clean up the flaps in stages. You may actually have to
ease the nose down a little for a
moment, depending on how you are trimmed out, just to get that airspeed up in
order to climb out safely. You DO NOT yank the column back but to me I can understand
how you may instinctively do that if ATC yell at you to “pull up!”
So here ends my language rant for today. I’m lucky in that I’ve had
plenty of experience in practising overshoots, both self-inflicted and ATC
mandated. It really is instinctual now but I still spend time pondering over
points like this!
* I had no idea what this was until she explained it to me!
** Apart from my old nemesis. He stresses me out.
*** Of course by admitting this on my blog. I’m fairly certain a
call to them is on the cards for the near future courtesy of Bob!
**** I had to pull up the weather for Vancouver to make my point.
CYTZ is currently in the midst of freezing rain and ice pellets, the METAR is
actually about half a page long!
