Lesson 28 – 2nd September 2009 – 1330 – 1 hour 6 minutes – Total so far – 29 hours 10 mins

Today was Quickstops, Autos, Simulated Engine Failure, Emergency Turns

G-MAVI was getting its 100 hour service, so G-BZBU was the bird of choice (HP variant), aka Northumbria02.

It has a David Clark Headset and was a much better experience on the R/T front than the old school headset in MAVI. I didn’t need Steve’s help with any R/T today, which is a bit of a change.

As per usual, I went out to do the checks and start her up. I used the new checklist that I’d done from the R22 manual after Scott’s comments from the previous lesson. It seemed easier for some reason.

When it came to starting her up, it was clear the starter motor wasn’t engaging and she wouldn’t start. After each attempt, I’d wait a while and try again, but nothing.

I got out and had a look and it looked ok to me, so I tried started it whilst I was outside the a/c and it turned over ?!?!?! Weird !!! I got back in to start it properly.

With Steve in and all the checks done, it was a Runway 25 departure, right turn out to Morpeth. En route to the practice area, we did a couple of autos to a powered recovery at 500feet with me doing throttle and controlling rpm, they went fine :-)

Then we did a steep descent to the plateau, but it was a bit too steep and to keep it safe, I overshot by 30 feet, rather than risk Vortex Ring.

Once in the hover at the plateau, we did 25 minutes of quickstops, precision transitions and clearing turn practice. The winds were quite strong on the plateau so the clearing turns were interesting, but I was pleased with them.

The quicksteps started off being too quick, my bad. But, as Steve said, they should be a gradual steepening nose high attitude to stop quickly (when you’re practicing them anyway). In real life, I expect you’d do them as steep as they need to be to stop before you hit whatever it was that caused you to have to do it in the first place.

By the 4th attempt, I was doing them ok and was happy with them. Between each couple of attempts, we were doing precision transitioning, which is seat-of-the-pants helicopter flying at its best. Whizzing along with a groundspeed of 50/60 knots, whilst being <50 feet above the ground is awesome. I _DID_ take the camera and set it all up, but because of the different headset in this a/c, it didn’t keep the camera angle, so all I have (footage-wise) is a couple of minutes of initial heli checks and then 1 hour PLUS of the ceiling of the helicopter. :-(   Gutted !!!! Because it would have been great footage.

On the way back, Steve surprised me with a simulated engine failure and it was definitely a surprise. But after a few surprise remarks, I pushed it down firmly and the first bit went well. Steve suggested a turn to get to a certain field and it worked out great. The last 5 seconds are full on, because about 50 feet from the ground, there’s a flare, collective, throttle and pedal work. It was over in a flash. I didn’t think I’d done anything at the end, but Steve said I’d done a fair bit, but definitely not the whole thing.

Absolutely bloody gutted that the camera was pointing at the ceiling, ‘cos I’d have learned so much by watching it back !!! And it would have been fun viewing too (for Karen).

Damn and blast it !

That aside, was a great lesson.
