Prior Experience

So having been checked out to Waiheke the day earlier, I got to put the lessons I had learned with Chris to good use on Saturday, flying some friends for a scenic and then dropping them at Waiheke for an afternoon of cafe's and vineyards before I picked them up and dropped them back at Ardmore.

The weather in the morning was a little marginal, which some low "scungy" cloud hanging around, making it hard to do any real scenic flying, but thankfully it was high enough that we could get into and out of Waiheke without too many issues. The weather had vastly improved in the afternoon, so we able to do some decent scenic flying around the gulf and the Hunua Ranges on the way home.

The wind had picked up in the afternoon, and while the Waiheke procedures state they prefer take-off's and landings to and from the south for noise abatement (ie. we don't want to annoy the neighbours by flying over their homes), I was not comfortable with taking off downhill with a 10 to 12 knot tail wind just to keep the noise down! I know that the 182 is capable of it (having had it demonstrated on another student's check flight to Waiheke a year or so ago), but the safety of the aircraft and those on board come first as far as I'm concerned. As it turned out, with a max performance take-off and the headwind, we were airbourne about halfway up the strip and we were able to easily make a right hand turn once airbourne to pass well clear of any homes to the north of the strip.

A satisfactory outcome for all concerned :)

Flying on faith

So I now know what faith is... it's the belief that the little needles on the little dials on the little instrument panel of a little aeroplane is indeed telling the truth.

1.8 hours of "faith" later, and I had literally worked up a sweat... the inside of the instrument hood was dripping :P

Today was ADF approaches. So instead of "comfortably" flying around at 2500' feet flying holds and tracking to and from NDB's, we left the safety of altitude and practised flying approaches to "minimums".

"Non-precision" Instrument Approaches (like NDB approaches) are designed to allow you to fly safely down to fairly low altitudes, as long as you are where you think you are (faith in the instruments)... the idea being that you drop below the cloud base, spot the runway and commence the actual landing part visually.

Flying to minimums basically means that you fly to the lowest altitude allowed and hope you spot the runway before you reached the "missed approach point", at which point if you haven't spotted the runway, you get the hell out of dodge and climb back up to a safe altitude.

As I was simulating instrument flying conditions with the hood on, I never got to see the runway... so every approach resulted in a missed approach, back into the hold and then time to setup for another approach.


And just because I hadn't had enough "fun" for one day, I went for a quick afternoon jolly with Chris over to Waiheke, to get checked out for landing there... the club have a policy whereby members must first fly a dual check flight here due to some interesting quirks that Waiheke has... like the 45 degree offset approach for runway 17 due to noise abatement procedures, this is also complicated by the the fact that the runway has a pretty pronounced downhill slope in this direction, so if the wind is a moderate southerly you are in for a fun ride ;)

Taking off uphill can also be a challenge as it's harder for the aircraft to the necessary airspeed while it's rolling uphill and then you need to outclimb the slope once airbourne...

Thankfully, the 182 has bucketloads of power and eats the strip alive... even with a moderate tailwind landing downhill! ;)

So after doing some p-charts to confirm that we could safely get in and, arguably more importantly, out again... we headed off to Waiheke, completed take-off's and landings in all directions to get a feel for all the approaches and to see that it actually makes more sense sometimes to land with a small tailwind because it's up the hill than to land down the hill with a small headwind!
