I highly recommend ASG for anyone looking to complete their ATPL theory training. Their instructors are incredibly knowledgeable and experienced, bringing real-world aviation expertise into the classroom. The newest state-of-the-art facilities create an excellent learning environment, and their online platform is well-structured, making it easy to follow along and stay on track with the syllabus.

What sets ASG apart is their ability to link theoretical concepts to practical aviation scenarios, which has been invaluable in preparing for exams and future flying. The flexibility of their distance learning option also made it possible to balance studies with work, flight training and everything else.

If you’re looking for a high-quality ATPL theory provider with top-tier instruction and cutting-edge facilities, ASG is an excellent choice!

The ASG ATPL distance learning course is second to none!

I was initially apprehensive about completing the ATPL theory while working full-time in the pharma industry. In the end I, passed all 13 exams first time, with an average score of 94.7% in about 10 months. I would not have been able to pull this off with out Diarmuid and his team!

The course is tailored to suit the needs of distance learners who have other commitments in addition to completing the exams. The course is self paced, and delivered mostly through the ASG Learning Management System. The LMS is full of pre-recoded lectures exploring at depth some of the most challenging areas of the syllabus. Also, you are never left by yourself during your ATPL journey. Diarmuid and the team are always there to answer questions and they are extremely responsive. Additionally, the LMS allows you to engage in discussion with other students on any issues that you might run into before or after the revision classes. The revision classes can be attended in person or online and that’s a big plus for the distance learners.

The quality of instruction provided by the ASG instructors is outstanding. All instructors I’ve had the opportunity to work with were very knowledgable, dedicated and approachable. Crucially all of them were full time plots, working with the Irish Air Corp or Aer Lingus. Therefore all content delivered during the revision classes was relevant, with real life examples.

Finally ASG never forget about you. They are always there to help you whether you’re still a student or a long time graduate.

I’m glad I’ve chosen ASG and I can’t recommend it enough to all modular students out there!

I chose ASG for my PPL theory as remote learning enabled me to balance the course with college, work, & other commitments. The learning management system is easy to navigate and interact with measuring your subject progression.

The instructors at the revision days went above and beyond for the students. They linked the relevance of certain aspects of the theory to the day-to-day operations of an airline.

The administration team is excellent. Before my final exam sitting. I was allowed to sit an extra revision day for navigation. The additional help the instructors & classmates provided outside of the classroom helped me understand any areas of difficulty.

In conclusion, I'm delighted with the product & service ASG gave. I passed my PPL exams on the first sitting & look forward to beginning my ATPL theory with ASG after my final year of college.

I did the online ATPL-theory course with ASG and I'm thoroughly pleased with the product. The ASG team were quick to respond and went above and beyond to answer all and any questions I had. The instructors are all knowledgeable and good at connecting the often abstract theory to real life operations, as well as providing techniques for dealing with the many difficult exam questions. I definitely credit ASG for making the ATPL-theory less daunting and more manageable!

ASG provided excellent support as I pursued my ATPL exams while working full-time. Their flexible scheduling allowed me to balance my studies with my job effectively. Thanks to their dedicated instructors, I successfully completed my exams and took a significant step forward in my aviation career. Highly recommend ASG for anyone pursuing their pilot license!

Having just completed my final exams this week, I can attest to the quality of the distance learning product offered by ASG for the ATPL theoretical knowledge course.

With small class sizes and experienced instructors that are mainly active airline or military pilots, the revision days were really engaging and offered unique insights into some of the key areas of difficulty that just couldn’t be hit by the books. I attended all revision days in person, which I found worked best for me, however, the option to log in remotely was a great perk if needed and the use of quality equipment meant that the whole class was engaged during each lesson.

The new online Learning Management System was also excellent for keeping me motivated and accountable throughout the course, offering hours of brilliant webinars and additional reference material for all subjects.

Anytime that I had any difficulties or concerns, I found the support team at ASG to be extremely quick at getting back to me, which provided great peace of mind during some stressful weeks.

Overall, my experience studying with ASG was very positive and I would recommend considering their product to anyone on their modular ATPL journey.

Simply the best organisation on the Island of Ireland for your ATPL theory (or PPL). They're so good in fact that you need to look overseas to find anyone good enough to compete.

There is plenty to say about them whether its (1) quality of training(modern technology, in class vs online etc), (2) quality of instructors (all current and highly experienced commercial and military pilots), (3) Service (outstanding attention to detail and attentive to each student... I could go on.

All i know is that I made it through my ATPLs because of them so i highly recommend them as your choice of ATO

Excellent approved training organisation for PPL and the levels above. The lecturers have deep knowledge in the field of aviation and commercial pilot experience. The two block weekend to complete the 9 PPL exams revision was pretty intensive but very helpful. Definitely will consider using ASG once again if I ever proceed with the ATPL route.
