I'm a product of both systems.

I certainly appreciated the FAA's: "memorize the test, rather than learn the knowledge" system, when it came to the Fundamentals of Instruction for the flight instructor rating. However, I can't count on a single hand the number of times I've had to apply the reasoning of how a chinook wind occurs in the plains (ie Calgary for you folks).

For the ATP, I had to calculate the CG of the 1900 and the DC9. Two planes of which I've never flown, and Lord help me, will never fly.

"Well Mr Nark, never say never!"

I've had to calculate the CG for a Beech 99, and the company used the same whizz wheel contraption for the 1900. For the ERJ and the A320 my company pays a lot of money to some Silicon Valley nerd who came up with a program that computes CG. I plug in numbers, it gives me a CG and trim setting.

Boom.

LEMAC can suck an egg.


Glass houses and such, we haven't landed a perfect good airbus short of the runway, or stalled it on landing either...

For my Canadian ATP, I had to learn astral navigation. And I think grid navigation,
but it's been so many decades I can't be sure now.

It would be nice if written tests stuck to measuring aviation knowledge.

Hey man, somethings gotta pay for the biplanes :^)

I'm quite proud I used a home made grid navigation map to fly from Eureka to the North Pole and back. Never thought I'd use grid navigation when I studied it for my ATPL, but hey, you never know :mrgreen:

Awesome! It's great when you can actually apply stuff that you had to learn.

Reminds me of an interview question of Elon Musk's (another ex-Canadian pilot):

You are at location X on earth. You travel 2 miles south, then three miles west,
then two miles north, and you are back at location X.

What is the exact location of X?

Are you missing a northbound leg? Or is it the sneaky 90 degree S?

My bad. Typing fast, not taking any prisoners, like those foreign soldiers in Ottawa.

Corrected.

You're on a latitude 2 miles north of where the circumference of the earth is 3 miles, on the southern hemisphere. Also pretty close to the south pole ;-)

I think Elon's answer is "the north pole" - you know, where you went? :^)

IMHO that's a pretty good interview question - for an engineer or a pilot!!

It is, and the north pole is the 'obvious' answer, but it also holds true for a latitude 2 miles north of where the circumference of the earth is 3 miles, on the southern hemisphere.
