Ardmore Taxiway Closures

UPDATED: Just a bit of a heads up for anyone intending on operating out of Ardmore next week- taxiway Sierra is due to be closed in parts for surface resealing work, between Wednesday 4th March and Friday 6th March, weather permitting.

This may lead to landing delays due to aircraft backtracking, and will be NOTAM'ed while work is in progress. The blue marks on the airport diagram below shows the portion of the airfield that will be closed on the 4th and 5th (the eastern end of taxiway Sierra past taxiway Alpha, taxiway Romeo that runs alongside AeroTech and the joining taxiway Oscar and Papa that lead to the 21 full length holding point). The red marks indicate the part of taxiway Sierra due to be closed on the 5th and 6th, from taxiway Alpha westwards to taxiway Delta. Displaced thresholds from both directions will apply during the NOTAM'ed period.

An alternative taxi route along taxiway Hotel and Juliet is marked with black lines, and new temporary aircraft parking areas are shown in green. See Gen 1.6 NZAR 53.1 for the comprehensive ground movement plate.

DC3 Type Rating

Something happened recently that I’ve been greatly anticipating for many months, something I’ve deliberately neglected to mention on this blog just in case it didn’t actually happen- and as many of you will have found out in aviation, exciting promises relating to flying often get made but then seem to fizzle out and get forgotten about all too easily!

I’ll start from the beginning to give this post some context. Back in 2007 I was introduced to the Ardmore based Fly DC3 team, formally known as the Warbirds Dakota, through a member of the PPRUNE community. I had been fortunate enough to be taken up for a flight in ZK-DAK’s jumpseat by the chief pilot who was keen to share his enthusiasm for aviating in the special aeroplane with me as a young teenager about to begin my flight training.

I’d stayed in touch with both guys over the course of the following years, and stuck my head in to the operation HQ on return to Auckland at the beginning of 2014 to volunteer my services as a ground assistant during my spare time that I had available around my aerial photography job.

At this stage I had clocked up around 800 hours total time myself, and I was told that in the eyes of the DC3 committee this was enough experience to be able to actually join the crew as a first officer. An unexpected offer was made for me to be added to the ownership syndicate at a feasible rate which I was very happy to accept.

By the time accompanying paperwork was complete and my funds were organised, it was early winter and the aircraft was scheduled to go away to Palmerston North for its annual maintenance during the month of August, at which time the chief pilot would be away on holiday overseas. A plan was made to commence my type conversion training upon his return in the Spring, however a propeller vibration issue that had been identified just prior to the annual maintenance ended up plaguing the aeroplane all the way through to December whilst various solutions were proposed and trialled before an entirely new starboard prop was bought in as a fix.

During the down time I had undergone some recurrency tail wheel flying in one of the fellow syndicate members’ Piper Cub for a refresher of ground handling concepts. These techniques had been pushed right to the back of my brain since the series of introductory flights I’d made Citabria ZK-CIT in 2007, long before I’d enrolled at Ardmore Flying School from where I’d begun flying tricycle undercarriage aircraft ever since. I had also sat a DC3 ground course along with a friend of mine who had been in same intake at AFS and since gone on to fly the aforementioned Citabria himself. The chief pilot recommended that the two of us undertake the DC3 training simultaneously, taking turns in the jumpseat to observe the other at the controls to enhance comprehension of new cockpit and it’s somewhat bewildering arrangement.

Fast forward Xmas and New Years holidays and mid January 2015 was go time. My friend and I had both sat in the cockpit a few times and ran checklists and touched levers to get ourselves comfortable prior, but it was the first engine start and takeoff that really made the wait worth it.

As expected, taxiing something near 70 feet long and 100 feet wide with a swivelling tail is a little more tricky that guiding a C172 with a steerable nose wheel along taxiways barley wider than the DC3 undercarridge track itself! In the air, whilst conventional to control, everything is just as heavy as you would imagine when looking at the aircrafts moveable surfaces, and the control column has far greater movement in all directions than any of the GA aircraft that I’ve logged time on so far. The turning radius is massive, even at airspeeds similar to the C310, and the effect of the trim is also super effective compared to the result of a few winds of the wheel in my light twin. Once levelled out, it is recommended that the aircraft be flown with the right hand on the yoke and the left hand on the trim wheel (from the right seat at least), which even with just 3 POB required continental adjustment as I got used to the feedback parameters. Above all however, the feeling of being in control of Douglas DC3 is more enjoyable than I know how to describe. Looking out of the flight deck window at the 14 cylinder Twin Wasp radial engine purring along, and then down the lines of rivets running along the curved bare metal wing still seems a bit like a fantasy than a reality! Expect many photographs to follow!

Over the two conversion lessons that I’ve completed so far, we’ve gone out over the Hauraki Gulf and looked at steep turns, emergency drills and asymmetric flight, stalling in various configurations- although recovering at the buffet up at 5000 feet as a safety measure. Circuits at Ardmore made up the majority of the second flight, with the First Officer (co-pilot) required to be able to land the aircraft by himself in event of Captain incapacitation, bearing in mind that the aircraft is usually flown with a two pilot crew, with a flying pilot and non-flying pilot on each operational flight.

We’ll continue with some further circuit bashing flights before the type rating gets signed off, ideally with a headwind down the runway rather than a gusty 17 knot crosswind that made things difficult for me last Thursday. This will then be followed by an annual check flight that once passed, will allow me to fly on commercial operations for the next 365 days.

So, if you happen to come out to Ardmore and join us for one of our weekly Sunday Scenic tours this year, there will be a chance that it’s me who will have the privilege to be sitting up at the pointy end of the aircraft during your flight.
