Great Lesson – it was quite a jam-packed lesson with lots of different things covered.

First off, I went out to check the helicopter out. It was the HP R22 model  (G-BZBU). This is a lighter version (one less fuel tank) and the battery is in the front, so the CoG is farther forward. This is the one where you feel like you do 2 takeoffs/landings for every normal 1 ie land the front of the skids, then the back and same in reverse for takeoff, but today I really noticed how much more power we appeared to have available because of the lower weight (less fuel).

I made a ballsup of the R/T today. As usual, I go out and check the heli out and start her up and get it so we’re ready for the off and then Steve joins me. But, I had forgot the callsign of the helicopter. All aircraft in the UK have a callsign something like G-ABCD and I knew that this helicopter was G-BZBU, but all the flying school’s aircraft have a more friendly name like “Northumbria ZERO ONE”, so when it came to asking for startup, it went something like this……….

dp :- Newcastle Tower, good afternoon, Northumbriaaaaaaaaaaaaaa. erm…erm……………. (I didn’t know the callsign and had to use the full name) “Golf – Bravo Zulu Bravo Uniform” at the Flying School with Information Juliet request startup.

Thankfully tower was very helpful !!

Newcastle Tower – “Golf – Bravo Zulu Bravo Uniform”, you have been booked out as Northumbria ZERO TWO. Information Juliet is correct. Startup approved”

dp :- “Startup Approved, MANY thanks. Northumbria ZERO TWO”

While everyone else is sounding dead professional, I come on sounding like a numpty. Ah well, live and learn.

Steve seems to be getting more confident in my liftoffs as he is crossing his hands on his knees now, whereas before he wisely always had a hand near the collective or the cyclic. Don’t get me wrong, he still often does at times, but not for the takeoff today, even though we were between a R44 and the fuel bowser. Taxi to Foxtrot and then we (I) basically hover-taxi’ed to a holding area next to the runway, awaiting an inbound a/c who was exiting at Foxtrot. There was one light a/c ahead of us wanting to depart too. Whilst we waited, Steve got me to practice a landing in the “HP” R22, just to feel the difference. I could kinda feel it, but to illustrate it better, he took control and very skilfully lifted off the skids and pivoted on the front of the skids. Quite amazing. It was like watching a ballet dancer go up on to the toes of her feet. He went up and down a few times, all the time pivoting on the front of the skids. I was impressed. Once done, we stayed on the ground awaiting another helicopter passing Foxtrot. Strictly speaking it was the light aircraft’s turn to take off first, but they couldn’t go because there was an inbound 737, but Newcastle Tower asked us if we could exit heading due North (past the control tower) going directly ACROSS the runway and not along it’s length (which runs from 070 to 250 degrees)

dp:- Affirm (with a big grin)

And we we’re off. We headed upto 2400′ and once out of the Control Zone, upto 3000′.

Today, we started off by doing Vortex Ring – Settling with Power. In a nutshell, a fixed wing aircraft can stall (fall out of the sky) if it goes too slow and the angle of attack of the wings is too high. The airflow gets very turbulent and the a/c loses lift because the airflow isn’t laminar (smooth) enough.

A very similar thing can happen in a helicopter. If a helicopter goes less than 30 knots (or more accurately has no transitional lift), and has a descent rate more than 300′ per minute, AND there is power being applied, you effectively stall a LOT of the rotor producing lift, and the helicopter, like a plane starts falling at a much higher descent rate. The more you pull power, the more you are pull dirty air through the rotor, the faster you drop. It sounded very hairy from the book, but at 3000′, you have quite a lot of time to fix it. The fix is easy (at that height), basically cyclic forward so the speed comes above 30 knots and then power and recover.

We did about four of them, and they were all event free. The controls go all mushy, there is a big yaw, and you drop like a stone, but you can’t feel it so much at that height. Cyclic forward, get speed, then power and recover.

So, with those over and with all the height we still had left, we did an autorotation down to the plateau. We were so high, I needed to do some turns to get rid of some extra height. The improvement today was that I completely did the entering. I think I’ve done this once before, but today, I really did the whole “entering into” autorotation. I also did the flare, but Steve did his final POP (as he calls it) and pulled the collective and then I continued the hover. We just did one of them. I’ll be pleased when I do one completely, ‘cos this is SUCH an important skill to have.

Once that was done, Steve asked me to fly to the centre of the plateau and for the first time, I didn’t fart on and hover at a snail’s pace. It felt like I “really” flew it there. It felt real good. A nice turn to finish and back into the hover. It felt sweet :-) A special moment for all the right reason. In a way, it felt like the first time I’d flown the helicopter by the seat of my pants, solely feeling how it flies. Hard to describe in words. Normally when I fly, everything we do, like an approach is a set sequence of events that you do in a set order. But, this was just FLYING A HELICOPTER – loved it. Once back in the hover in the centre of the plateau, we did a (fake) landing and then we did a takeoff and a practice obstacle avoidance. So, in a nutshell, Steve took control flew us at about 60kts (quite fast, when you’re so low) at a mound of earth and then at the last second (all very safe!) sharp cyclic left and up and PULLED collective. The result was a very sharp turn. Quite a few “G” being pulled.

Of course, Steve, the comedian he is, had to get a few jokes in. “Imagine that mound is a Merlin Helicopter” (he said) (referring to the near miss we had a week or so back !). AND OF COURSE, me concentrating so hard, I didn’t get the joke until about 10 seconds after he had said it. But then we were laughing at that as well :-)

So, Steve showed me one and then I did the second one. I felt Steve come on the collective, probably ‘cos he thought I wasn’t pulling enough of it (or too much), but I got the idea and was happy with the maneuvre.

Then we went straight at the mound but this time for a QUICK STOP (as they’re called). In a nutshell, this involves stopping the helicopter very quickly into a stationary hover. That was lots of fun. I was happy with that, but my turn comes another day. He just wanted to show me that one.

Once done, back to the airport and we were fortunate again for being a helicopter. Because there was an inbound Airbus. The Tower asked if we had a visual – we did, and then they offered us an expedited landing clearance ahead of the Airbus. Now, in the past, Steve has done this expedited landings, but he let me do it. Another seat of the pants bit of flying, so much fun !!!!!!

I need to get out of the fixed wing mentality. In a normal plane, you line up with the runway, and land on the runway, and most of the time, in a helicopter you do the same, but at times like these, when we’re expediting in front of a fast approaching airbus, I don’t need to “land” (transition) on the runway, so although I did a fast approach (about 80kts), I needed Steve to suggest use the grass next to the runway, but he was great and let me do the whole transition to the hover and then taxi clear, well in time for the Airbus landing.

This is where I’m disappointed with the result of my flying. I hover-taxi’ed to the parking spot. It was between the R44 and the fuel bowser. I positioned us nicely in the middle, spot turned it so it was lined up correctly, all good so far and then it all seemed to be MESSY !!! I think I’m being too much of a fanny when it comes to the touching the ground bit. I am trying to get ZERO movement in any direction whatsoever, but the end result is I am demanding (of myself) the absolute perfect hover before touching down. Well, of course, I would get to within an inch of the ground, detect a smidgeon of movement sideways and then abort, rinse and repeat, rinse and repeat ! I was up and down like a Yoyo ! It must have took me 30 seconds to do the last ONE FOOT. Will have to ask Steve next time about this.

Credit to Steve, he didn’t butt in and sort it, which is great, ‘cos that would have left me frustrated. Anyway eventually, I got it down, but wasn’t too pleased with the landing. It was safe, but not as sweet as I would have liked.

All in all, great lesson. Lots of variety. Loved it, shame about the crappy ending, but that’s my bad, and I’ll have a word with myself before next time.
