This dynamic training programme that uses the latest in speech recognition technology to help students improve their pronunciation. The pronunciation training begins with an assessment. 

Students can choose to work through the pronunciation training curriculum systematically or use the “Intelligent Tutor” to prioritise the areas on which the student should concentrate. So for example, a student may not need very much practice in saying the “w” “v” sounds, but a lot of practice in saying the “j” “y” sounds.

The grammar content of Climb Level 4 is based on a needs analysis of the grammatical points required to reach ICAO level 4 and above. The ICAO descriptors for grammar level 4 say: “Basic grammatical structures and sentence patterns are used creatively and are usually well controlled. 

Climb Level 4 gives students extensive practice in both the basic and more complex grammatical structures of the English language. The grammar exercises are accompanied by a grammar reference book. The exercises are designed to improve students understanding of the form and meaning of a range of structures and tenses; they contain extensive practice in the syntactic features of all the structures taught. The grammar curriculum is taught using text based exercises and speech recognition based exercises.

The vocabulary exercises have been designed to help students with word recognition and production, the use of words in context and the correct production of words. 

The curriculum is designed so that the lexical items taught are revised several times over to aid language retention. The exercises have been designed to appeal to students with a variety of learning styles. 

Language is presented aurally, in text and pictorial form. Students are able to save words they want to revise in the Aviation Word Book. They can translate them into their first language, and annotate the example sentences and definitions.

ICAO level 4 requires students to comprehend both routine and non-routine situations. Climb Level 4 provides extensive practice in listening to pilot-controller communications. These have been written by aviation personnel who also have a teaching background and reflect the reality of controlling several aircraft in the same airspace. The listening comprehension texts reflect realistic problems and emergencies. The curriculum also includes aviation news stories and “Flight School” programs which look at best practice in improving aviation safety. The comprehension curriculum includes:

  • A wide variety of international accents
  • concept checking exercises
  • the target vocabulary and grammar taught in the curriculum

Fluency & Interactions

ICAO level 4 and above requires students to “produce stretches of language at an appropriate tempo”, and to give “immediate, appropriate and informative” responses to messages. Personnel are also required to deal with misunderstandings by “checking, confirming and clarifying”. 

Climb Level 4 has a variety of exercise types to help students improve their fluency and interactions. One major cause of disfluency is pausing to access grammar or vocabulary and so many of the fluency exercises within each module are based on the grammar and vocabulary that is taught in that module. The exercises move from controlled production to freer production. For example, students

  1. Read sentences fluently (controlled production)
  2. Listen to sentences and then repeat them (interactive readback)
  3. Describe images (free production)

In each of the exercises, the student is given feedback about their pausing and rate of speech. The fluency and interactions curricula also contain a wide variety of international accents.
