Sustainability Spotlight: Future of Sustainable Aviation

Glenorchy Air is committed to providing our customers with an experience that is as sustainable as it is spectacular. We have already begun our fleet upgrade program to replace some our smaller aircraft with larger, quieter and more efficient types such as our brand-new Cessna Grand Caravan EX’s Built by Textron Aviation in Independence Kansas, USA.

We chose these aircraft as they are the safest and most efficient aircraft in their class, burning only 11-12 litres of Jet Fuel per seat on a Milford trip with unmatched reliability. These aircraft are already certified to run on Sustainable Aviation Fuel (SAF) and in line with our core company values; a primary objective is to be the first Queenstown Operator to use SAF when it is available in New Zealand.

There is currently a Turbine/Electric Hybrid grand Caravan EX in development by Surf Air Mobility, which is due for flight testing around 2024 and this engine will be retrofittable into our aircraft as their current engines come up for replacement. The Hybrid system is expected to reduce emissions and fuel burn by at least 25 percent on current levels. Read more about this here.

Electric Aviation

Glenorchy Air is closely following the development of pure electric aircraft and Our Managing Director James recently attended a presentation by Textron Aviation on E aviation. Textron has recently acquired Pipistrel Aviation, a Slovenian and Italian based company who developed and certified the first pure electric light sport aircraft in Europe. This aircraft, the Velis Electro, is a small two-seater plane and has an endurance of 50 mins with a 30 min reserve. This is not big enough or long enough to sustain our operations, but this innovation shows us that electric aircraft is on the horizon.

The biggest barriers to electric aviation’s expansion are weight of required batteries and the slow pace of certification, especially for new propulsion systems. Whilst there are many start-up companies out there with some incredible concepts but they’re limited by the technology that’s currently available. Regulators around the world will not rush to certify designs before all safety requirements are met. That said, we will be there every step of the way working with manufacturers, regulators, government and industry to allow us to meet our vital sustainability commitments as quickly and safely as possible.

As an innovative business looking into the future, we are very excited about where aviation is heading. We plan to be the leaders in embracing this future, likely starting with SAF, moving to Hybrid options on the way to a fully zero emissions aircraft as technology advances.

Scenic Flights
How long is this trip?

This is a Half Day experience. From check in 30 minutes before departure, to landing back at Queenstown Airport, is approximately 5 to 5 1/2 hours. Please note, this does not include time for self-driving or using our complimentary transfers. If you have plans immediately either side of your experience with us, please let us know.

What time is best to fly?

It’s always a good time to fly! If the option is there, we would suggest either our 9.00am or 1.30pm departures. Please note, our 1.30pm departure time is only available at certain times of the year. Whilst we cannot guarantee it, Milford Sound can sometimes be a little bit quieter at these times.

What should I bring?

We suggest you bring the following with you to make it a great day out:

  • Any essential medication
  • Sunglasses
  • Sunscreen
  • Bug Spray
  • Camera – make sure it’s fully charged
  • Warm clothing layers – you’ll want to enjoy the open-air viewing decks where it can get chilly
  • Sensible footwear
  • Bottle of water
How long is the scenic flight?

Your flights between Queenstown and Milford Sound are approximately 40 minutes each way.

How long is the cruise?

Your Nature Cruise through Milford Sound with our partners Southern Discoveries is 1 hour 45 mins.

Is food included with the cruise?

No, lunch is not included. When making your booking online, you have the option to add a picnic lunch for an additional cost that will be ready for you on the cruise. We have vegetarian, vegan, and gluten free options available.

Complimentary tea, coffee and water is available. A selection of small snacks are available to purchase onboard. You are also welcome to bring snacks of your own.

Your cruise through Milford Sound is on a boat with a large open-top deck and comfy interior cabins with full-height windows for optimal viewing. Take in the stunning scenery of Mitre Peak, Stirling Falls, Copper Point, and the Tasman Sea. Keep an eye out for seals, dolphins and penguins.

Is the cruise suitable for an infant?

We would say the cruise is suitable for all ages.

Is there a nappy changing facility/station available inside the cruise?

Yes, there is a nappy changing facility onboard the cruise.

What happens if the weather prevents us from flying back to Queenstown?

Our pilots will always look at the forecast for the full duration of your trip and if we feel like the weather may change, we will not leave Queenstown. Due to the weather-dependent nature of flying in the Southern Alps to Milford Sound, it is unfortunate that there are very rare occasions where the forecast changes on us and although uncommon, it can be a case that we are unable to operate the return flight. The safety of our passengers is always our highest priority and in the unlikely event that this ever occurs, we will arrange coach transfers back to Queenstown. We fully appreciate the inconvenience this will cause and do everything we can to look after our passengers.
