@cyilroy - dude, your the man...
I totally agree with you. I had my private oral for 3 hours, Instrument 4 hours and Commercial took 5 hours. Was totally exhausted after the commercial oral check. My examiner flies Bombardier Global Express Jet and has around 30000 hours of flight experience.
And people think FAA license holders doesn't have have ground knowledge as their written is really simple, but they don't know that most of the ground part is covered during our oral check.
