Pre-Solo TOD

Flight #: 054
CFI: Kristie H.
Aircraft: Robinson R22 Beta II
Aircraft ID: N2223P
Duration: 1.5hrs
Cumulative Time: 61.10hrs

Weather has been total crap for the last week. Hailstorms, almost daily. When it was not hailing, it was 25 knot winds. Of course, all this was with 500ft cloud ceilings too.

So, as you might guess, not a flight.

Today, however, was perfect. 50º, sunny, with calm winds. Perfect for my pre-solo "Triangle of Death" flight. Pretty uneventful flight, actually... but that is a good thing. Only issues were that I had the wrong frequencies in... twice. Stupid stuff that I caught as soon as I did not hear anybody on the channel... but still. 135.65 when it should have been 135.67, and 129.09 instead of 129.9. Just need to double, triple, quadruple check myself.

Oh, and apparently the common "report 1 mile south" reporting point used by the tower is not actually 1 mile south. I was about 2 miles south of that point and said "3 miles south" when giving my current position... and was promptly corrected that I was actually 4 miles south. Huh?


Here is how it all works. Portland Hillsboro Airport is a Class D airspace, which means there is a 3D cylindrical solid, centered on the tower, with a 4 mile radius, extending from ground level to 2500ft above ground. In this case, the airport is at 208ft sea level... so therefore it actually extends from ground level to 2700ft. Before you enter Class D airspace, you have to let them know you are coming... and what I told them was that I was already inside their airspace. Not cool. The sectional map shows it like this:





Obviously a map does not represent the real world perfectly... so if we were to draw the same airspace on a satellite map you would see something like this.



Anyway, the point here is, the 2 mile ring actually touches on something all the pilots and CFIs call "The Goal Posts". The goal posts are two cell towers that act as a great visual reference for your way back home from the south. From up close, they look like... well, goal posts. You can click on the image for a larger view, but they are there. And, they are pretty easy to see from a few miles out.

So, as you are headed north, back to HIO, you thread the goal posts and head straight in to the airport. You just follow the road in at 700ft and you will come right in line for an approach to the ramp. Nice and easy. Just like this:
All seems pretty easy, except that they call the goal posts, "1 Mile South". So, I reported where I was in reference to those goal posts... I was telling them that I was already in their airspace. Turns out, while I was reporting my position incorrectly, I was actually not violating their airspace at all... I was actually just on the edge.
See, the "1 Mile South" point is actually 2 miles south.

You learn something new every day. I suppose I should have picked up on this already. Nothing like a mistake to get you focused on getting it right next time.

So, all in all, fantastic flight. The proof? Kristie cleared me for my Solo Cross Country!

Hoping for nice weather tomorrow.
