Joanna, after asking me the answers to the questions mentioned in the previous post said that I should post them. Because otherwise you guys might not understand how ridiculous it really is.

The mental grouping of affiliated perceptions is called A) insights.

Which of the student’s human needs offer the greatest challenge to an instructor? C) Self-fulfillment.

Individuals make more progress learning if they have a clear objective. This is one feature of the principle of B) readiness.

I think I’m about ready to take that test anyway. Unfortunately, I’ve got to have an even better memorization of it to parrot back in the oral exam. I’ve heard that the examiners do indeed want to hear everything just like it is in the book.

I’ve done 5 flights in the CFII course so far, the most recent this morning. I’ve got another one at noon. I got to fly in the clouds today, which was good practice. My instructor even had me do two no-gyro approaches in the clouds. “Are you sure about this?” I asked him. “I’m comfortable with it, if you’re okay with it.” “It’s fine with me, as long as you don’t let me kill us.”

“No-gyro” means that the two vacuum-driven gyroscopic instruments are covered up. This is to simulate a failure of the engine-driven vacuum pump, something that is bound to happen eventually. Particularly in training operations, because the vacuums pumps are generally not replaced preemptively as they are in passenger carrying operations. In a multi-engine airplane, it’s no big deal because there’s two engines and two vaccum pumps. They’re not likely to fail at the same time. In most aircraft, the attitude indicator (sometimes called the artificial horizon) as well as the heading indicator are driven off the vacuum pump. The attitude indicator works off of a dual-gimble mounted gyroscope that gvies you a constant reference to straight and level flight when you can’t see outside. If it’s working, it’s the instrument that’s most looked at in the clouds. The heading indicator is a gyroscope that only displays heading. You might think, “But you have a compass, so what’s the big deal? Why do you need this thing anyway?” The magnetic compass is a postively wretched and near-worthless instrument unless it’s a perfectly calm day and you’re flying straight and level. If it’s at all turbulent, the compass swings this way and that. If you’re turning toward north, the compass lags the airplane by as much as 30 degrees, and if you’re turning toward south, it leads the airplane by almost 30 degrees. For no-gyro instrument training, a fair amount of time is spent on what are called “compass turns”– turning the aircraft to a specified heading using the compass alone. For everything but large turns, it’s actually much easier and more acurate to fly timed turns. A standard rate turn equates to 3 degrees per second. You figure this out with the third gyroscopic instrument on the plane– a rate of turn indicator. It’s electrically powered so that if the vacuum pump dies, you’ll still have ONE gyroscopic instrument. (Conversely, if the electrical system dies, you’ve still got the other two. Airplanes are all about redundancy.) Unfortunately, it provides no pitch information and only indirect bank information. Flying an instrument approach this way is pretty difficult– and is the most difficult task required for either the instrument or flight instructor-instrument ratings.

I flew two no-gyro localizer approaches today. Even more tricky because I had about 40 knot tail wind, because the localizer approach is for runway 3 and the wind was out of the southwest.

We’re supposed to do NDB approaches this afternoon. I’ve never actually done one in an airplane. They’re miserable. NDB stands for non-directional beacon. Which means the only navigational information you’ve got is an arrow that points in the direction of a beacon. And not very consistently at that, because the beacons are relatively low-powered and low-frequency. Almost anything will make them inaccurate. Thunderstorms, shore lines, mountains, clouds, night, temperature inversions…
