CASA UAS Airworthiness Framework

CASA has published a discussion paper for AUS Airworthiness.

CASA Airworthiness Discussion Paper 2

The points of discussion were quite wide ranging and will have an impact of many sectors of the UAS industry. We have tried to place a focus on elements that may become appropriate for CoaX Helicopters.

Here is our response:-

UAS Airworthiness Framework #4


The full CASA UAS Airworthiness Discussion paper is below


The Race to AHIA

CoaX Helicopters was invited to display and present at RotorTech 2016 courtesy of the Australian Helicopter Industry Association , AHIA.

We had allow a month to manufacture the H37 engine mounts, configure and fit the MoTec and G3X displays, build a new console and prepare the 20′ helicopter for departure.

But not everything goes according to plan! A number of hurdles were thrown out to challenge us and it wasn’t until 6 days before we were due to leave did we receive the engine mounts. Without those we would have to cancel.

On Sunday and Monday we fitted the engine mounts and engine


On Tuesday we collected the MoTec C187. Fortunately the engineers at MoTec had gone above and beyond to load the display data and configure the electrical system to power the display.

On Wednesday all players gathered to pull it all together. Jim Azar worked all day mounting and wiring the Glass displays and finally we had power on the machine


The console to hold all of the components together arrived at 5 pm Wednesday. The panels we still in pieces and had to be fitted.

By 9 pm that night we finally had a finally had the helicopter on the trailer ready to go.

We departed at 8 am Thursday morning, phew!


MoTec C187 Selected

CoaX helicopters has been working on development of a suitable rotor and engine RPM display. After considerable research with our own internal design we found a much more suitable option.

The MoTec C187 was designed for high performance racing cars but is now creating display/data loggers suitable for military vehicles and aircraft.

MoTec C187 First Design

The display can be configured to display a vast array of information for the pilot. It also has an integrated data logger which we intend to use as the heart of our HUMS kit.

During our flight development we will be able to track flight parameters both in-flight via radio communication and after flight by downloading all of the performance data.

The display shown is our ‘first draft’. We expect significant changes in the screen layout as we gain further understanding of the capability of this vital asset

RotorTech 2014

Peter Batten recently presented an update on progress at CoaX Helicopters and discussion regarding RPA (UAS) and Optionally Piloted Helicopters during RotorTech 2014


Maroochydore – Here we come
Rob Rich, secretary of the Australian Helicopter Industries Association AHIA, approached to CoaX to attend RotorTech 2014.

We decided to take our 17′ R & D helicopter recently fitted with a Garmin G3X and one of our older 20′ helicopters to the event in Maroochydore QLD.

We were provided with a booth which attracted a great number of attendees. Visitors were drawn to our stand by the outstanding video presentation created by Mike Collins from ImageTraders.

On the Flight Line
We fitted rotor blades and lined up in prime position amongst the dozen or so helicopters that were flown in for the event.

David Earle, John Stewart and Richard Woodward fielded questions non stop for the duration of the 2 day event.

Manned, Unmanned or Optionally Piloted
Peter Batten was requested to make a presentation to AHIA.

He described the progress CoaX Helicopters has made, future directions for CoaX and the discussion point of Optionally Piloted Helicopters.

Most importantly Peter, in conjunction with the AHIA symposium, declared that Pre-orders of the 17′ CoaX helicopters are now open. Details are on the Buy Now page.

Grape Vine Anti Frost Management by CoaX UAS

New Zealand is a major producer and exporter of grape vine products. Weather conditions in winter can sometimes cause devastating crop loss due to frost.

To mitigate the effect of the low altitude inversion layers trapping cold air which then settles onto the vines, helicopters are used to mix the air and reduce the chance of the freezing.

CoaX UAV helicopters would be ideally suited to this role. It would be possible to pre program the area to be flown, the altitude to operate at and even the temperature and moisture conditions at which the vines would be vulnerable.

The CoaX UAS could launch completely autonomously and complete the task. As CoaX UAS would know the terrain and local obstacles, the likely hood of accidents would be significantly reduced.

The cost of a CoaX UAS unmanned helicopter system over time would be far less than that of a traditional manned helicopter, with the added advantage of increased operator safety.

Bush Fire Management with CoaX UAS

The recent devastating fires in Victoria have once again highlighted the destructive force of nature if left unchecked. CoaX Helicopters has been approached to investigate providing incendiary dispensing capability from the CoaX UAS as an unmanned system.

It is often difficult to access wilderness areas to initiate back burning during non hazardous weather conditions.

CoaX UAS drones could easily be fitted with a combination of optical systems and dispensing systems to carry out this task.

During bushfire season, CoaX UAV drones could also operate with thermal imaging systems to identify the fire front and possibly people in danger.

Larger versions of CoaX UAS could also provide fire suppression roles, operating safely in restricted visability conditions such as heavy smoke and night flying, giving firefighters a unique opportunity to extend fire fighting operations.

SBS World News Promotes UAS Debate

SBS News has aired a Channel 4 news article on the pros and cons of Civilian UAS.

It will be vital that the UAS industry regulations are constructed in a way that UAS operations are safe and compatible with current manned aircraft operations.

Ethical as well as legal concerns will need to be well considered before Civilian UAS become a part of our every day lives.
