Day 4 - Big Bay and Milford Sound


The first three days of flying in South Island had been a gentle introduction to mountain flying with blue skies and light winds (with perhaps the exception of flying around the back of Mt Cook).  The principle is to fly along the right hand side of a valley unless wind turbulence requires a different approach.  In low cloud conditions when approaching saddles, low lying ridges used to cross from one valley to another, the trick is to approach at an angle to allow the option to turn back if the other side is not clear and always have an escape plan.  As a result drawing a line on a map to determine and plan your route simply does not feature in mountain flying, as you weave you way around and through the mountains.

Day 4 was going to be some of the more challenging flying getting across to the west coast for a beach landing on Big Bay, followed by a flight round and into Milford Sound, a deep and steep sided fjord that has an airstrip at one end, and then on to Fjordland in the South West corner of the island, otherwise known as Peter Jackson’s film set for his Lord of the Rings films.

Milford Sound has a specific set of procedures for arrival and departure because of the narrow fjord and valleys leading in to the airfield.  More details can be found here: http://www.transport.govt.nz/about/Documents/NZMF.pdf  and www.caa.govt.nz/safety_info/GAPs/Milford_GAP.pdf
New Zealand pilots are well used to the discipline of self-reporting and Milton Sound additionally has an information (radio) service but not full ATC, so approaching pilots have to keep an eye on other traffic, a good listening watch as well as flying the plane.

You quickly get used to the idea that on many strips a long finals approach, sometimes even a short approach is not always possible.  So getting the plane set up early is vital to a successful landing. Windsocks are not always visible or available so overflying the strip is a must.  On day 3 our challenge was to land on the beach at Big Bay which is around 8km across and 8km wide and touch down on sandy beach across the back of the bay – so as runways go – pretty long.  Landing aircraft usually land and park at the north end, so with the prevailing southerly wind, we still ended up hugging the mountain at the north, to touch down just over a small creek.
 
Entry to Milford Sound
A short landing roll with yoke well back to stop the nose wheel digging in, we slowly taxied back to avoid picking up stones from the prop and parked facing out to sea.  As we went for a walk around the dunes to take a look at the whitebait fisherman’s huts I mused over the number of beaches we could land on in the UK – with such freedom. The “white-baiters” are only there for a few months a year and there rest of the year the bay is only visited by trampers (hikers) and the odd aircraft.

Short finals for 11
Next stop was Milford Sound and short track down the coast to join from the seaward side.  Strict adherence to flying on the right and hugging the hill was reinforced when the narrowness of the gorge became apparent.  Saint Anne Point was our first reporting point with a decision yet to be made on whether to land on 11 or 29.  Whilst there is flexibility on landing there is little on departure because of the steep mountains close to the end of the runway.  Equally go-arounds on 11 are not encouraged for the same reason.  There was quite a lot of traffic in the sound with a number of planes departing and the three Cessna 172s in our fleet, about 5 minutes apart.  This was going to be the least straight approach I have ever flown with a short final for 11 to the left after rounding the last cliff on the right.

  The wind at the top of the sound was negligible and rather than fly a tight circuit round the back for 29 we were told that 11 was available should we want it.  Trying not to think about the prospects of not getting in cleanly, it was down soon after the numbers.   Rather satisfying!  After lunch and a short exploration of Milford we were off to Fjordland.

 Assuming we would track back out the same way we were surprised to find we would be leaving through the overhead to track up the Arthur River to carry out a circuit of Lake Quill.  Most circuits are going around something in the middle – like a runway. This circuit was going to be going around something on the outside as Lake Quill is a high level mountain lake with an amazing waterfall down to the Arthur River.   The aim was to cross in to the lake over the waterfall and then lose airspeed to 70kts and put out one stage of flap.  Hug the hill was again the message as we flew round to the right for an anti-clockwise circuit.  It was a weird feeling flying around the inside of a circular mountain tarn with one entrance and exit, short of a very slow, high climb out over the top.  The views were simply amazing and it was slightly off to fly out over a huge, huge drop.





Flying out through the Arthur River we traversed a number of saddles and across an number of the inlets in Fjordland until it was time to head to Manapouri, an underused airport, with PAPIS, departure lounge, hard runway and no planes or passengers.  It had been developed by the local authority to encourage traffic and tourism to the area, though the ANZ flights had finished.  We had a break in the airport cafĂ©, from the hot drinks and cakes we brought ourselves.  After refuelling ourselves and our aircraft it was time to head back to GHS for dinner.
