Clear As Crystal

So last week was the following question:

Should conditions warrant exterior surface anti-icing protection, which specific windows in the Boeing 777 flight deck will activate with this protection?


The two most important windows for both the commanding officer and the second:


And now on a more technical level..  (Time to throw a curveball)

Clear Air Turbulence (CAT, not to be confused with "Category") is down right difficult for the naked eye (of a pilot) to detect. To the 777 , special radar for this is in place by selecting two switches.


Which switches activate this radar and when will the CAT radar appear on the Navigation Display?

Stay tuned for our answer next week!



  1. All I can say is I knew, I knew. But the Boeing is my passion, and it makes sense to only anti-ice the forward windows.

    So... the weather radar. I don't think it can see Clear Air Turbulence. The radar actually needs precipitation to be available to see turbulence at all. So is this a trick question?

    1. Haha! I knew you knew! Boeing is a passion in itself. Also an obsession. When I typed the post I meant to word the question differently to make it appear not as tricky but I will say this we should fly the 777 sometime and I'll take shotgun. ;-)

  2. It's already activated on the photo given. (Just a guess)

    1. Alex, that is a great guess. I say we all fly the 777 and you and I take turns riding shotgun.

    2. hahahahah I love that!

Looking into the eye's of the passenger profile photos of some of those on board after having read this book, I could never begin to understand what was going through their minds during their final thoughts and moments alive on aboard Air France flight 447.

A 26 year old doctor from Ireland, an 11 year old student from the United Kingdom, 29 year old Brazi…

Pure Perfection


One of those most grand moments in life is where we discover and cherish the perfection within the imperfection.

Have a great week everyone.  Take nothing for granted whether its perfect or not.

Flight For Sanity

"While it’s tempting to play it safe, the more we’re willing to risk, the more alive we are. In the end, what we regret most are the chances we never took."

With seconds to go, I was making a mad dash down the concourse.  Of course my gate had to be the last one at the end.  The chances of me making the next flight out after to the concrete jungle were growing very slim.  In the distance, I could hear a small boy ask his mom, "Why is that man running?"  Barely hearing anything over the sounds of rushing blood and adrenaline, I heard the mother explain that I was running to catch a plane.
As I ran, I flew into my subconscious and thought about the times where I wish I had ran towards something, risking everything valuable in life because of something I believe in, instead running of away from something due to fear of how bad it would impact my life.   Risks that were worth taking, that I never…
