Absolutely brilliant lesson – Loved it !!

Got a chance to listen in Rich’s helicopter debrief as I arrived (another student). It’s always good to chat to fellow pilots and trainee pilots and it’s quite reassuring to know that others face the same obstacles and hiccups. Good to know I’m not alone !

Once Rich had gone, Steve did an in-depth briefing on Confined Area Landings. I was glad of hearing it a second time, because it takes a few briefings sometimes for things to sink in. I was overwhelmed before the last lesson and during it, but today the briefing cemented my knowledge and the actual lesson felt really good – kind of like everything came together.

So, Steve booked out, as I went out to G-MAVI (Northumbria01), checked her over and started her up. The ATIS was not very healthy today. It gave the surface wind, temperature, dewpoint and that was about it. No runway in use, no pressure settings and no Information designator. So, I was thinking how I could get that across to Tower without rambling on for 2 minutes, but thankfully some other pilot was already reporting it and from that conversation, I could tell they already knew there was a problem too.

Startup Checks are starting to flow much better now. I’m not fluid, far from it, and still have to check the checklist, but I’m getting to the point where I’m checking a section heading and remembering the X number of things in that section. So, I’m getting quicker at it, without forgetting things, which is good.

With Steve onboard, we taxi’ed to Foxtrot and then a left hand turnout from a 07 departure. Normally, I climb to 2300′ but today that would have put us above the cloud, so we kept about 1500′. We still skirted cloud which is a lovely feeling, don’t ask me why !

Once out of the zone, we headed to a wooded area next to a prison. En route, we rolled the power back to see how much was required for 53 knots level flight and I think we had 6.5 MAP available (plenty) and we then started the first of two orbits around the confined area. Steve had said to keep the confined area at 45 degrees at all times. Not too sure I did that exactly, but after a few more attempts I’ll get that. Certainly, I circled it working out angles of entry and departure. We looked for the S’s.

  • Site
  • Surroundings (inner/outer)
  • Surface
  • Slope
  • Stock (Livestock)
  • Sun

and some other S’s I’ve forgot. But basically, a handy way of thinking about all the things you have to be aware of.  There were some pylons on the approach, and some telegraph wires on the departure. But, it was like a mini runway as far as space was concerned and I was confident we could get in and out.

After 2 orbits around the confined area at about 500 feet, we made our approach. I’m not forgetting applying Carb Heat with any descents these days, but I am forgetting to cancel it at 500 feet, which is particularly important for confined areas where you need all the power available. Note to self !!

The approach to this confined area went much better than the previous ones with Scott where I had to abort the first one and it’s dawned on me why. When I did them with Scott, although we didn’t know it at the time, we were landing downwind (i.e. with the wind behind us). No wonder I struggled to slow it down and get it in. But, with the wind towards us today, it was so much easier. Once in the confined area (basically a strip of land surrounded by trees), we did some more of the turns where you move to the right, turn to the right, move to the right, turn to the right. They went fine. We then taxi’ed back to the trees at the downwind end, so we had ample space for the transition. I think we then did another power check and we had about 1.5 MAP available for the departure (again, ample for a vertical or towering takeoff).

And then we did a normal transition to leave the confined area and flew straight into another orbit (for practice). A second approach and hover concluded the second practice confined area landing. We didn’t actually land because….

  1. We’re not allowed to land away from a licensed aerodrome and
  2. The grass was so tall, the tail rotor would have been in the grass

So, with the second approach done, Steve suggested trying a towering takeoff. What a lot of fun. As the name implies, we pull full power (24.5 today) and then we zoom up and as we stop gaining height, start easing it forward and transition away. Awesome !

With that done, we headed back to the airport.

On the way back, Steve said we were going to practice an autorotation to a power termination. Basically

  • full lowering of the collective
  • throttling off the engine
  • enter autorotation
  • find a suitable field
  • setup an approach
  • Flare at the last second
  • POP the collective and
  • HOVER

The first one went well. I managed the throttle initially, all good, but as I stopped the rotor rpm from rising into the red (by pulling collective), the correlator told the engine to get back unto speed. So I learned that you have to HOLD the throttle off and stop it correcting itself. Good tip !!!

Steve later said that I’d done 95% of the whole thing. I was chuffed, ‘cos I’d put it more at 80%, but everything happens so fast, especially towards the end when you’re flaring 50 feet above the ground etc….

So, I thought we were all done. I made the call at Morpeth to ask for rejoin instructions and we’re heading back to EGNT. Totally to my surprise and completely OUT OF THE BLUE, Steve says “Engine Failure Engine Failure Engine Failure”. Well, without even thinking I instinctively lowered the collective, and turned into wind. I took a moment to think “what the hell” and then remembered to stop rotor rpm from rising into the red. I think I even remembered to hold the throttle off on this one. I did feel Steve do something at some point, maybe some minor throttle work, and then at about 300 feet we went around.

Loved it. It was a total surprise and a real test for the panic that would be there (but tenfold) were the engine really to quit. I was pleased that it was kind of instinct too. My only concern is if the engine really went and noone was saying outloud “Engine Failure Engine Failure Engine Failure” would I still lower the collective as quick. ;-) LOL.

Anyway, thinking the lesson over, we climbed and headed back to EGNT. We were asked to do a couple of orbits on left base for 07.

Here’s the GPS of the orbits over the Golf Course..….

With the landing aircraft down, Steve made a radio call and asked if we could do another auto onto the runway and that was ok with them, so we did another auto to a powered termination and that went well too. Steve said I did 99% of that one. I think he helped with the throttle on that one too.

So, brilliant lesson – one of my favourites so far and that’s with a landing rated 4/10 on the dp scale. The landing was safe, but one skid touched first and then when they both touched we clunked down, not graceful, but we made it ;-)

So, all good !!!

Here’s the trip we did..….

Lesson 29 – 10th September 2009 – 1125 – 1 hour 6 minutes – Total so far – 30 hours 16 mins

Thursday, September 10th, 2009

The whole of the UK enjoyed a magnificent day of September sunshine today due to a massive high pressure system. It was gorgeous for flying. As smooth as a mill pond !

The order of the day was mainly instrument flying. It’s an area I feel quite comfortable with, probably due to my fixed wing days.

So, slightly different start to the flight as Steve accompanied me out so I could test my headset in various different helicopters and different radio/helicopter headset combos. It worked swimmingly in each. With that complete, he headed in and I did the startup checks.

The Lightspeed Zulu headset felt great on, a real comfy fit and when ANR is switched on, a lovely calm settles in your ears, quite an eery silence. Even with the rotors turning, it was a huge improvement on a school headset.

Usual startup done, the headset had their first real test. Normally, I am straining so much to hear what’s being said, that there is a sense of slight panic as I try and catch every word Tower is saying to me. Today, I could hear them so clearly, I could actually _listen_ to what they are saying even if it was different to what I was expecting. And that happened..…

I had got the QNH from the ATIS, and it was a very high 1038mb. When Tower gave it me with the taxi clearance, they gave it me as 1033mb. Now, normally, I would just be so grateful to have understood what they said that I would have repeated it back to them. But today, I had the wherewithal to ask them to confirm the QNH was 1033mb. They corrected the QNH to 1038mb and I was chuffed that the painful purchase was already paying dividends.

As Steve did his final walkaround under the fast-spinning rotor, I did the final “Low RPM Horn” checks and we were ready for off once he’d took his seat.

Steve wanted me to do all the checks once in the hover (lights out, temps etc in the green) and then record “power required to hover” and state “CoG and Controls feel fine”. I did that. Before I even took off, he checked I knew the maximum Manifold Pressure we could tax the engine to. It was 24.5 for 5 minutes, because of the high pressure system.

Short Taxi to Foxtrot with Steve now onboard. The hover lift was fine, and so it should have been with the Surface Wind less than 5kts. Today, I had decided I was going to do things more by the book. Hold altitudes, follow taxi lines etc etc…. Normally, I don’t tax myself too much and enjoy the moment. But, as I found today, I can do both.

For the first time, once we were cleared for takeoff, I didn’t skip the corner (over the grass) as I normally do, we did a precision transition, akin to fast taxi following the taxiway line (ish), turn into wind and off we went. It was so smooth today. Today’s are the kind of days you don’t want to come down.

At 500 feet, I had Scott’s FREDATT (Fuel, Radion, Engine, Direction, Altimeter, Trim & Transponder) checks running in my ears, so I did them.  And then off we flew to the North. Initially 2300ft but once out of the zone, it was instrument time. We first did a couple of turns (180 degree at 15′ rate). They went fine, and then it was time to put the goggles on. They are goggles that allow you only to see the instruments and a bit of land either side of the instrument pedestal, but nothing that would help you fly. I suppose if you see blue sky either side of the pedestal column, it’s a clue to commence panicking.

I had to remove my headset to put the goggles on – WHAT A RACKET !!!!! I’ve never removed any headset before in a helicopter, and blimey, you can tell why you need them. So with the goggles (and headset) on, Steve gave instructions. First off a 180′ turn to the right (15′ rate), whilst maintaining the current height. And then same in the other direction. They went fine.

Then we did a climbing 180′ turn and a descending 180′ turn. Again, they went fine, although I did notice they were getting sloppier and I could sense I was losing concentration. But, they were safe.

We ended up at about 3200 feet and Steve suggested we leave it there as he didn’t foresee any difficulties with instruments and for us to do some autos, but first he suggested going upto 4000 feet to see what it looks like from that altitude.  Off we jolly well went to 4000 feet and WOW !!!!!! There were a few clouds about and we were above them. That’s a first for me in a helicopter.  It felt awesome. I suggested to Steve that we land on one as they were nice firmly shaped puffy ones, but he didn’t seem keen. :-)

Once past the clouds, we did a 180′ autorotation with me doing the throttle again. They still feel so new to me (autos). Whereas it doesn’t tax me much to fly the helicopter generally, even to hover now is RELATIVELY stress free, but autos seem to need 100% cpu cycles. So, HASEL checks then collective down and roll off the throttle. I rolled it off, but they crept back on because I hadn’t rolled off enough and the governor was kicking in. But, eventually I got it to a steady 70-75% rpm. We were nicely in autorotation, now the turn. Whilst the turn was under way I called the fake mayday. I seemed to get everything out. Pretend to turn the fuel off, the magnetos, the master switch after first pushing the ident button and we were down to picking a field to land in. With that picked, we came out of the auto at about 1000 feet and proceeded to the plateau. Just as I write this, I have remembered that I forgot to “check above” (for the climb away) which is the last thing I’m supposed to do in an auto. I did remember cancelling carb heat. Note to self!

So, once at the plateau we practiced a steep approach. 30 knots indicated and a steep angle of approach. I was aiming for a certain point, but overshot it by about 50 yards, but I’m good with that. It was good practice keeping 30 knots and the high angle of approach. Apparently, these skills will be used shortly for Confined Area Landings shortly.

Once in the hover at the plateau we did a hover taxi back along the plateau, a 180′ yaw and then we did a practice quickstop. That went ok. It was then time to head back to the airport.

An uneventful trip back (we like them) and a chance to catch up with a bit of chatting. We were asked to report overhead Stannington, which I did, and then to report base leg. A bit farther on and before I had chance to report base leg, Tower advised us we were number 1 to land, to report finals and be aware of an Easyjet who was entering the zone from the south and who would be coming in behind us.  So we kept on the speed (about 90kts). I said to Steve, it would have been better if they’d let us join midway.

Steve :- Ask them Dave. Say “Northumbria01 request midjoin”
dp :- Tower, Northumbria01 request midjoin

And we got it, which basically meant we didn’t have to cross the numbers at the bottom of the runway,and we could cut the corner and “land” midway up the runway. We did that and transitioned to a taxi just before Foxtrot and then taxi in. We didn’t even get chance to fully vacate before Tower was granting the Easyjet landing clearance.  All good though !

The landing was ok. It wasn’t a dp spesh i.e. up and down 10 times, but neither was it a 10/10 like I have done before. It was an 8/10 in my book. I went down to land and sensed sideways movement and then pulled up and went down again for a toe landing. It felt like the front skids touched down first and then the rest gently touched down after that. It felt very safe and I was pleased.

So, great lesson. Days like today are meant for flying. I would have had another lesson, but they were fully booked. I’ve turned my single lesson tomorrow into a double. Already looking forward to it !!!
