THAT WEATHER!!

Tuesday 13th December

Warm sector depressions - don't you love them!  Low cloud, poor visibility in rain or drizzle, uncomfortably humid, etc, etc.  Yesterday it was much like that here in the Waikato and similar this morning, although the overnight rain had stopped.

However, as the morning wore on the cloud lifted and my chances of getting up at 1300 looked more hopeful.  I checked the ATIS online before driving off to the airport and cloud base was 3500' - quite flyable conditions but only locally.  Tauranga had a cloud base of around 1500' with poor visibility in drizzle.

I arrived at the club to fly Cessna 172, WAM, which has just had a full engine overhaul (i.e.; new engine cylinders and internals in original crankcase), and got a quick briefing from Roger on engine management: 2500rpm at all times in cruise, don't spend too long on engine run-ups, no glide approaches, cross country only - no circuits.

So, after preflight I got going without undue delay.  It was fairly light traffic-wise given the weather and I took off from 36R in a slight crosswind turning right to leave the zone to the NE via Scotsman Valley.  I flew just below the clouds at 2200' as far as Morrinsville where the weather was a bit clearer and was able to get up to 2500'.  I flew a big circle to the North of the airport turning to the West at Lake Waikare to return via Huntly.  I kept a careful eye on the RPM gauge and was pretty consistent throughout the cross-country part.  It got a little more challenging when planning the approach.

I was cleared for a Rukuhia arrival and descended to 1700' prior to entering the zone.  With throttle setting for 2500rpm the airspeed crept up into the yellow zone, 140-145Kt on descent.  Hmm, could be interesting getting the approach speeds low enough.  It was!  At Rukuhia I was advised the surface wind was 060º at 12 knots and I took the option of landing on 07.  This proved a real problem as I was still at 1700' and I ended up on a short final way too high and at about 95 knots - time to throttle up and go around.  I did a fairly wide left hand circuit to give myself time to get the speed and height down on final with minimal low rpm time for the engine and it worked out OK.  The wind was more like 030º now so it was a crosswind landing with just 20º flap getting into a sideslip attitude at about a quarter mile out and a pretty smooth landing resulted with the upwind (left) wheel down first - always pleasing, that.  Another 0.8 hours running-in time for WAM's "new" engine and in my logbook.

A couple of photos to show the conditions:
