Latitude is a UK-based company dedicated to the design, development and delivery of quality specialist aviation English language training and testing solutions.

Our mission is to help our customers achieve:

  • Training efficiency: We do this by providing training and assessment products and services that target the language skills that students need for successful English-medium professional aviation training. This minimises the risk of costly and disruptive failures for our customers.

  • Enhanced safety: We do this by providing training and assessment products and services that target the critical work-related language required of licensed operations personnel.

What makes Latitude different?

We are different because we are dedicated solely to the language needs of the aviation industry. Latitude is not an English language school or an aviation training organisation. Unlike many of our competitors, aviation English is not an “add-on”. At Latitude, aviation English is our core business.

Our passion lies in creating high-quality specific purpose training and assessment solutions in a context where safety is paramount and training quality and efficiency essential. We have a proven track record in developing and delivering training and assessment services from short courses for small groups in the UK to large-scale fully-tailored programmes delivered at the customer’s preferred location. Our flexible delivery options enable us to tailor a response to meet your exact requirements. In everything we do, we strive to optimise training efficiency and cost effectiveness while minimising disruption to operations.
