Double Block

Flight #: 025
CFI: Kristie H.
Aircraft: Robinson R22 Beta II
Aircraft ID: N8340S
Duration: 2.4hrs
Cumulative Time: 27.0hrs

We had a double block (2 x 2hr) of flights today. That affords you so much more time to practice and enjoy yourself. So, we flew on up to Scapoose, OR and did our patterns there. Was great since it was a 7am flight and we were the only people in Scapoose until about 9am.

Got in another first today. Refueling away from home. Sounds silly and trivial, but it was a milestone for me. Felt like getting gas on a long road trip. Get to stretch your legs, check out new scenery.

Just a fun day.

(Autorotation)^5

Flight #: 024
CFI: Kristie H.
Aircraft: Robinson R22 Beta II
Aircraft ID: N7155W
Duration: 1.2hrs
Cumulative Time: 24.6hrs

Ok, so I already told you that aurorotations were incredibly cool maneuvers. They are. What's cooler? Well, rather than doing them at 2000AGL (above ground level), try them at 500ft AGL. WOW! All the same maneuvers, but this time you just have the ground coming up at you rather quickly. The engine is idle and the governor is inactive until you reach about 40ft AGL.

Man, my heart was pounding. But, after the 4th or 5th time, you start to get the feel of it all and if just comes to you. Which, is the point, of course. That day will come, when you need it for real... might as well be overly prepared for it when it happens.

There are different classifications of engine/power failures; >500ft AGL, <500>8ft AGL, and <8ft AGL. The first introduction at autorotations we did were at 2000ft AGL, this set was at just over 500ft.

Obviously, the lower you are, the less time you have to react.

Ace!

Flight #: 015
CFI: Kristie H.
Aircraft: Robinson R22 Beta II
Aircraft ID: N8361N
Duration: 0.8hrs
Cumulative Time: 15.8hrs

Best session to date. Well, eventually.

Things started out rather messy. 61N was to be used, the previous night, for an aerial photography session. As such it had the left door and left controls removed to allow for a passenger with a stack of cameras to move freely about. Apparently they also were planning a significant flight since the tanks were maxed out on fuel.

So, it spend the night out in the open, no door in the freezing cold. The windows were covered in condensation and everything needed warmed up before we could start. During the oil check I found that we were a little low and I had to go get some to get back to the school's 5 quart minimum. Line service had not had a chance to replenish the engine oil stash so I had to walk all over the place to find bottles with any oil in them.

Line service is responsible for general maintenance on the aircraft and they are the ones you are supposed to call for any fuel issues. So, I called them and asked to have fuel taken out (as I'm only allowed to fly with 16 gallons. They want to get people flying as fast as possible and filling takes priority. So we had to wait.

Once we had everything checked out and were ready to go we tried to start 61N. No go. Nothing. Starter would turn over, but the engine would not catch. Clearly it was because it spent the night in the cold, wet air. After the 6th try we got it rolling.

Once we got into Charlie pattern we ran a few laps and each one was spot on. I really think the key to it was recognizing ETL... both for take off and for landing. The only way to describe it is that you want to keep in the sweet spot... and that happens to be ETL. You can tell because of the slight vibrations felt through the helicopter. It is very slight at the beginning, builds to a max, and then trails off.

It was easiest for me to Imagine a bell curve. As you approach ETL you start getting small vibrations. You know you are headed the right way or doing the right thing when they build little by little. You want to stick to the green section and ride the vibrations all the way in/out. If you end up doing the wrong thing or don't act fast enough you will end up out of the green.

Ride the vibe all the way and you are good to go. One thing to note is that the helicopter also tells you when you are doing something very wrong with vibrations as well. I'm told they are not little or slight... but really hardcore and bone wrenching. As I said... it is all about feel.
