Flight 3: Sat, Oct 19: The First Approach. (.9 / 8.4)

My flight instructor surprised me today by asking whether I had approach plates. I hadn't bought them yet because I thought we were a few weeks away from doing instrument approaches.

First we went to the practice area and reviewed steep turns, slow flight, and timed turns. Then I got an intro to flying with a partial panel, in which some of the instruments are covered as if they weren't working. I found it easier, since I had fewer things to watch. (If I could "lose" a few more gauges, I'd have this mastered.)

I did some turns using the compass, with the heading and attitude indicators covered. (A compass does not show the correct heading throughout a turn, so the idea is to learn how to compensate for compass errors while turning to the desired direction.)

We went to Lakeland (LAL) to do my first ILS approach. I hadn't expected to be attempting one this early, so I hadn't read about them or studied the approach plates. I'm not sure that would have made a difference, though, since most of the approach went by too fast for me to understand much. I guess approaches are the instrument training equivalent of landings- something that is learned more by repeated practice than by being taught.

My instructor did the radio work, talking to Tampa Approach and the tower, and I tried to do the flying. I was all over the place trying to follow the glideslope, which showed how far off I was in two dimensions. Soon we were down to 600 feet, close to the runway, and I had to take off the foggles and land. Transitioning to a visual landing after all the hood time was not easy, since I'm not used to suddenly finding myself on final.

I'm glad I got an early exposure to the approach. It's going to take a lot of time and effort to Iearn, so now I can go read about the procedures having a little experience doing one.

On the way back home, without the hood, I got a lesson in intercepting an NDB bearing. We finished with some crosswind touch and goes.

The weather today was so nice that it was a shame to spend most of it under the hood, so after the lesson I did a solo cross country flight. There probably won't be too many IFR-related tasks I can practice by myself, since I can't use the hood without another pilot, but today there was one. I picked a couple of airports with NDBs and used the ADF to home to each one. The visibility was so high that I could see downtown Tampa from a few miles west of Disney World. That's about fifty miles.


Flight 4: Sun, Oct 20: Please Hold. (.9 / 9.3)

We reviewed some more basic manuevers today, and then I was introduced to a holding pattern. I flew straight for a minute, did a turn to the opposite direction, straight for a minute, back to the original heading, etc.

We did a VOR approach at Lakeland. I found it more confusing than the ILS, and definitely less precise. When I took off the hood, I was above 1000 feet, between two intersecting runways, and not sure which one we were cleared to. I didn't think we could salvage a landing from that situation, but my CFI explained that we were about where a real IFR approach would have taken us, so I need to get used to landing from there. On the way back we worked on intercepting ADF bearings and VOR radials.

This morning at our airport there was a midair collision, with no serious injuries, that kept the runway closed for several hours. This is the type of conditions in which these accidents usually occur- in good weather, with high visibility, near uncontrolled airports.

Go to the next flight.


Glossary

approach plate: A diagram which shows the procedures for a specific instrument approach at an airport. It is usually one page in a booklet which covers one or more entire states.

glideslope: A device used for instrument approaches. Two needles, one horizontal and one vertical, indicate whether the plane is on the correct descent path. (Actually, the glideslope is just the horizontal needle, and the vertical one is the localizer, but the entire instrument is often called a glideslope.) It doubles as a VOR.

ILS (instrument landing system): The most precise type of instrument approach.
