Unfortunately, I am not rated to fly this aircraft yet, so I had to take my instructor along. I need 10 hours total time in this aircraft to be type-rated, so that leaves only about another hour for me. This aircraft is designated a "complex" one because it has a different propeller system and has retractable gear. It is traditionally used by the students who are working towards their commercial license because the exam requires that you be familiar with the different systems. Not to mention that it's just a really cool plane to fly!

You might be wondering how the propeller system on the "RG" is different from a standard Cessna 172. Well, take a look below. The picture to the right is of the 172RG, and the one on the left is of a standard 172. Can you see the difference? If you can't see it, look where the propeller goes into the spinner. The angle of the propeller for the RG can be adjusted, while the prop for the standard 172 is fixed-pitched. Another name for an adjustable pitch propeller is a constant speed propeller. This is one reason why the 172RG flies faster, because the angle/pitch of the prop can be adjusted to allow


So, I mentioned before that the bad weather was a good thing, and now I'll explain why since you probably think I'm out of my mind. Since I've received my Instrument Rating, I've barely been able to put it to use in actual IFR weather conditions. Actual IFR conditions refer to weather conditions with 1000ft cloud ceiling and 3 miles visibility or less. I could always go with an instructor or safety pilot and wear "foggles" (a type of google that lets you look down at your panel but not outside the window), but flying in the clouds and low visibility always makes my day for some reason. So, when we departed Queen City airport for Harrisburg, the cloud ceiling was at about 700ft and the visibility was between three and five miles if my memory serves me correctly. We were also in the clouds the entire way to Harrisburg, and the first half of the flight ended there with an ILS (Instrument Landing System) approach. Unfortunately, I could not take any videos or photos in-flight because the workload was too high at the time and I did not want to distract myself.
However, to demonstrate an ILS approach in low weather conditions, watch this video of a LAN Boeing 767 landing in Santiago de Chile. Essentially, an ILS is a system which provides vertical and lateral guidance right down to the threshold of the runway. In other words, it's a very accurate system which provides a descent path for you to follow along with alignment of the centerline of the runway. The descent path that we follow is called the "glideslope", and the system that provides lateral alignment is known as the "localizer".
At this point in my career, the lowest I can descend on an ILS is down to 200ft above the ground. That altitude is called the decision height. If I do not have the runway environment in sight at that point on the approach, I must discontinue and conduct a missed approach, or as some people may know it, a go-around. The reason I cannot continue below 200ft on an ILS is because the aircraft I fly are not certified to conduct the approach below that altitude. The type of ILS that I fly is known as "Category 1", which signifies the decision height of 200ft. There are also Category 2 and Category 3 (a, b, or c) approaches. These approaches are only conducted by commercial jets which have been certified to meet the special requirements regarding the autopilot. On these approaches, the autopilot flies the entire procedure, including the landing. To see the chart for the approach that I conducted into Harrisburg, go here. Tell me if your mind exploded after seeing that.
So, the landing into Harrisburg was normal, and we taxied straight back to the runway for our return leg to Allentown. We were off the ground again in five minutes, and a few minutes later we were cleared on course to Queen City airport. We still flew in the clouds the entire way to Queen City, but by the time we arrived the cloud ceiling had lifted a little and was VFR (Visual Flight Rules) conditions once again. Nevertheless, we conducted another instrument approach (http://www.naco.faa.gov/d-tpp/0809/05171R7.PDF) and landed into Queen City.
So, that was about it for this week's flight. Next week there's a possibility that I'll be flying to Potsdam, NY for a college visit at Clarkson University, but it is rather far and so my parents are still considering it.
