Advanced Weather Forecasting & EWINS

2024 note: There are no EWINS classes currently scheduled.

We are proud to announce our new updated EWINS (Enhanced Weather Information Systems) course. For the first time, an aircraft dispatcher school will provide EWINS training in house. This is not “Orientation to EWINS” as prescribed in a common Aircraft dispatcher certification course, and what other schools claim as a true EWINS course – our curriculum matches the outline prescribed by the FAA for EWINS certification. Sheffield is offering a 2-day EWINS (Enhanced Weather Information Systems) training course.

Our course is an EWINS-qualification program, not a 5-35 minute lecture on the theory and concept of EWINS – it is the application. After completing the course and receiving a certificate, the individual will not only be more astute at weather analysis, but will be in a more favorable position to become EWINS-certified if their airline deems it necessary for their dispatchers. Basically, it’s a head-start into advanced weather analysis, whether you become certified in the future or not.

“This was an amazing class! Always interesting! It was like drinking from a fire hose, but I have never enjoyed a course more than this one. Thank you for a great 5 weeks & EWINS!”

“Brilliant instructors, first class education.”

Dear Sir,

Hope you are doing well. 
I wanted to write a few words to express my gratitude towards one of the most humble and knowledgeable human – you, my super instructors Rueben and Michael, ever so kind and helpful Brett, and last but not the least the lady who answered numerous questions throughout the process with a smile Ms. Lizett. 
I was excited to choose Sheffield because of what people around me in aviation told me. I am glad to say I have become one of those today encouraging others to join Sheffield. There were many amazing things about the course but for me the exams were the best. They had me thinking every single time, and now that I am working in the dispatch environment it makes complete sense. Everything I learned in Sheffield was practical and I can apply it in my daily work. For the future students “EWINS was my favourite workshop and I highly recommend everyone doing the course to definitely experience it. Please download the ADX app, trust me you won’t regret it. I had my classmates download it few days before the test because they could see how helpful it was.”
More power to the real Heroes “The Dispatchers.” If there is anything I could ever contribute towards Sheffield, I am just a call away. Please convey my regards to all. Thank you Sir.

One thing I kept in mind the whole time I was at Sheffield, is the reason I chose the school over others. It will be tough, busy and overall enjoyable. I haven’t had a single day I would say I could have missed. Look out for those tests, not only do they test your knowledge but they really make you think (you would know after the first one). Please do the workshops, they are really helpful, especially EWINS. Best of luck and see you on the other side!

“The AIFP, ETOPS, & EWINS courses provided additional information and understanding on the topics that I did not have (earlier). The courses were worth attending and I would recommend that others attend.”

  • Is there an age limit for enrollment, I’m 53 years old?

    No. In fact, knowledgeable hiring managers should view maturity as a “plus.” You may encounter perhaps one in three managers who are too young to understand that concept. A manager should ask to see your dispatcher certificate, and ask if you attended Sheffield School, verify that fact, then test you prior to an interview, etc.. I’d rather hire a wiser mature person who studies hard and is motivated, than a younger individual who is bright, but more interested in the local bar scene.
