Refining Aircraft Trajectories for Simulation

We have been working on improving aircraft profile trajectories in our simulator, and have used ADSB data to model real aircraft performance against the published Eurocontrol data.

Of initial interest is the climb and descent performance in the Terminal Area. We analyzed over 10 million squits from 32,000 flights grouped by type and came up with some interesting conclusions.

Online Simulator Development

Earlier this year, the VV team made large parts of our course-ware available free-of-charge to ATC trainees affected by the COVID-19 pandemic. Over four hundred students from ten different countries have used our technology over this period.

We used the Microsoft Clickonce technology to deliver our PC-based simulator from an online Learning Management System. This technology requires a large initial download and has other well-known shortcomings.

We are now looking at using different techniques to deliver simulation across the web that will enable full performance measurement reporting into the LMS, as well as gamification and other great features.

We are in late development at the moment and plan to have a testing platform available in September 2020.

VV Plus Evaluation

The VV Team have been working on applying our expertise in ATC procedures and Speech Recognition technology to create an English language trainer designed specifically for controllers.

The product is called VV Plus (Phraseology and Language in Unusual Situations) and targets the interpretation of radio exchanges, particularly non-standard and unstructured transmissions.

VV Plus contains pronunciation, speaking, listening and interpreting tasks.

The initial version is for Chinese speakers, and is under evaluation in China. Find out more in this information video (Chinese narration):

Free Access to Courseware

Visual Vectoring has been looking at ways to support our clients and the wider ATC industry during these times when training is becoming more difficult to deliver.

We have invested some effort into porting our instructional and simulation content to be accessible online. This has been made available to our existing clients.

We have taken the further decision to allow access to much of this courseware, free of charge, to prospective or current ATC trainees who may have had their careers delayed or interrupted. We are hoping that our technology will be a welcome and constructive use of their time and will also accrue some benefit when training is resumed.

It is anticipated that access will be available for the next six months, and includes formative training in Enroute/Area surveillance control (VV Enroute) and Terminal Area surveillance control (VV Approach).

This offer is available on request. If you are interested in gaining access, please contact us.

Note that instructional content can be viewed on any device, but an English Language Windows PC is required for simulation. If you are an instructor and would be interested in monitoring student performance, we'd be happy to set up a portal for you within our LMS.

COVID-19 Response

Visual Vectoring has has suspended site visits and will be working from home as of today, Monday 16 March, until further notice.

During this time we will be looking at making elements of our course-ware available online for access by ATC trainees who are suffering an interruption to their studies.

More information to follow.

Product Development

In response to customer requests, the VV Team has been hard at work developing some additional training products which will target phraseology and language in emergency situations and other aspects of Terminal Area ATC. Expect further information on these in early 2020.

Partnership with Cognishift



VV have partnered with Cognishift Technologies to incorporate pronunciation checking into selected VV training products. This functionality will be able to compare expected phonemes for a particular word or phrase with those produced by the student. It will be of great benefit to users of VV courseware in the improvement of their pronunciation of standard and non-standard ATC phrases.

Installation at CAUC


Last month, VV training specialists visited the Civil Aviation University of China (CAUC) in Tianjin to support the use of our training products: VV Enroute and VV Approach.
These products are installed on 180 CBT computers, and up to 600 CAUC students will be using them each year.

The VV Team were given a tour of the impressive Tower Simulation Lab (above), which contains a bank of 32 positions configurable for combined or individual training. It is the largest installation of its type in the world. In addition, a full 360 degree Tower simulation, which will make use of the latest LED technology, is under construction.

We look forward to assisting CAUC training exports in making best use of VV technology into the future.

Visit to Jilin

The VV Team has paid a visit to the Changchun ATC Station in Jilin, China to discus ATC training and other competencies.

The impressive Tower, which features a waterfall mural, houses the Approach and Tower training centres. The simulation was state of the art.

Like most airports in China, Changchun is experiencing significant traffic growth. Plans are being made to invest in more infrastructure to support the increased complexity and traffic levels.

We were warmly received and look forward to visiting again.

VV Management released

The development of the VV Management tool, used to organise and analyse student performance data, has been finalised. The newly released initial version is currently being tested by end-users.

The tool allows for:

  • Collection and collation of student simulation performance records using a LAN;
  • Student credential management;
  • Student path-tracking;
  • Analysis of data for comparison with previous performance, within the cohort and between cohorts;
  • Report generation.
  • VV Management is an invaluable tool for delivering VV technology, and will be included with selected upgrades and future installations.
