Eirin O’Grady
I highly recommend ASG for ATPL theory. The instructors and class content are of the highest quality, ASG are responsive and reliable, any queries I had were responded to within just hours!

I particularly liked the link between the books and real life while I was studying, it was great hearing instructors personal experiences on the line as it helped me to see beyond ATPLs👩‍✈️

I achieved 13 first time passes in just 6 months, with an average of 92% across all of the exams. I cannot thank ASG enough for their help and support along the way, remote learning is the way to go! I made connections with fellow ATPL students whilst attending revision classes, and was included in a WhatsApp group where we shared exam tips and study content. Thank you ASG.
Gerard Doherty
I'm extremely impressed with ASG, the team, their content and the online platform for learning ATPL. They make it super easy to understand the flow of your course, tips, and all the other bits you wouldn't think of. When it comes to queries and questions, Diarmuid and the team are super friendly and very quick to respond with quality answers and knowledge. Their referral program is very good too.

Keep up the great work lads.

Thanks.

I would really recommend ASG, I had a wonderful experience joining a PPL theory course and found it very inspiring and informative. The instructor was great, and worked one on one with all the students.
Eden Oreilly
Recently completed my ATPL Theory with ASG. Cannot speak highly enough about them. Their professionalism is second to none, the quality of their online learning system is excellent and the quality of teaching and instruction both in the classroom and online is fantastic. I highly recommend ASG for either PPL or ATPL theory.
Aly Coyle
I would highly recommend ASG to anyone working towards their ATPLs. I found the subject matter for each topic to be incredibly thorough and the quality of instruction was extremely high with the instructors all being very experienced, knowledgeable and professional. They were also very good at explaining complex subject matter in a clear and straightforward manner and also at providing great advice on exam technique.
The course was tailored to my needs and very flexible, with all materials and learning platforms being easy to access, use and understand. I ended up passsing with an average of 97.5% and this was definitely in large part due to the very high standard of the materials and instruction provided.
The entire team was incredibly supportive, they really care about your success and often went above and beyond to help me through the process. I genuinely cannot recommend ASG highly enough.
Andrew Tulyk
A great ATO that was extremely helpful and friendly, Excellent and very knowledgeable staff and lecturers. I would highly recommend ASG to anyone who would like to do their ATPL theory.
Florian Hambach
Back in 2020 I did my ATPL theory with ASG. Course was laid out perfectly. What I appreciated the most, was the flexibility during the times of Covid. Everything worked out perfectly.

Now, 5 years later they still reply to emails within a couple of hours and provide me with needed documentation, from years back. Amazing !!!
James Mcsherry
Very enjoyable and advanced learning environment. Subject areas specifically tailored by instructors with an in-depth industry knowledge to focus on more heavy and complex material that some students may not understand. An ATO that primarily focuses on a more structured and personalised training experience to enhance your overall learning journey, I’d highly recommend ASG to any future students considering their ATPL’s. Already looking forward to my next classes!
Michael Henry
Absolutely top class delivery of course content. Easy to follow platform, helpful instructors and staff setting you up for success with your ATPL examinations. Highly recommended!
Gary Naughton
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!
Simon Kenny
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.
Lucas Skalleberg
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!
Dan Earley
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!
Sarah Dungan
I would highly recommend ASG to anybody looking to complete ATPL/PPL theoretical exams. Having completed the PPL theory, I can testify that the standard of instructing is superb, the classes are small in size and questions encouraged/welcomed both by instructors and other class members. They are tailored to areas that are causing difficulty and the instructors really go above and beyond. Over the two weekends I attended all of the instructors were active airline or military pilots and could give added insight to the different topics based on their own experience.
The team at ASG were extremely helpful wherever I ran into difficulty and overall I felt very supported in the lead up to the exams - any queries I had were tended to with a high degree of professionalism and attention. I wouldn't consider anywhere else.
Niall O'Shaughnessy
Highly recommend ASG for ATPL and PPL theory. Their learning management system, instructors, interaction from staff, and setup are all exceptional. From minute one my experience with them has been top notch.
Andrea Terragni
ASG ATO.

They have been an important part of my career and with their help I’ve achieved more than I could have ever hoped.
Kind, professional and always ready to help.
To anyone thinking about applying, don’t worry, you couldn’t find a better school!
Brohna Tinnelly
I couldn’t recommend ASG enough. Easy access to High quality training along with highly educated instructors who work in or have in-depth knowledge of the industry. Any questions or emails are replied to in a timely manner, & most importantly you feel supported along the way, which is so important when in the process of such a big step in your career. Thank you Diarmuid & Team! 💫
Johnny Barnewell
I am currently training with ASG pursuing my ATPL exams. I looked around a lot before choosing an ATO but in terms of affordability and quality of teaching and course content I found ASG to be superior to anywhere else in Ireland or the UK. Having attended the in person training courses I can vouch for this. The knowledge and teaching skills of the guys doing the sessions is first rate most are very experienced commercial and/or military pilots so they really understand aviation science in detail and can make it relatable. Overall very happy with ASG and their help in achieving my goals.
Cillian Coleman
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.
Pejay Cooke
For anyone thinking of doing your ATPL exams you cant go wrong here. The instructors are excellent and the level of support you get from the ASG team makes getting through the course that bit less stressful.
Jack Craig
Excellent ATPL Theory setup. Passionate and knowledgeable instructors who go above and beyond to ensure you are fully prepared for your exam sitting. The instructors clearly enjoy what they do and this feeds into the quality of the product you get! Diarmuid in particular is fantastic and is incredibly supportive and responsive to any queries and issues you may have , even after you’ve completed your ATPL Course. Highly recommend.
Lithuanian Man
Best choice for ATPL study in my opinion, unlike in other ATOs you can attend their lectures online and don't need to physically be in the classroom unless you want to. Other ATOs make you go to way more lectures than you need to, at ASG you one need to do 9 days of lectures total, instead of weeks, at least personally I think lectures don't do anything for you in terms of getting better marks in your exams so it's time best spent doing question banks instead. I got over 90% in all my exams without even opening any of the books either thanks to ATPL Questions (.com), they are god sent.
Karl Morrissey
I couldn’t recommend ASG highly enough with the high standards of support from a team of highly experienced pilots with all the latest technology to assist every student from home to classroom.
cormac hudson
Fantastic ground school.
Would highly recommend and my experience here has been great.
