Air Service Training Ltd (AST) is a wholly owned subsidiary of Perth College UHI, part of the University of the Highlands and Islands (UHI). AST remains a world leader in the field of Aviation training and has been since 1931, making it arguably the longest-established organisation of its kind.

The AST engineering training facilities are situated on the spacious Perth College UHI campus and also at Perth Airport, which is four miles north of 'The Fair City' of Perth in Central Scotland. It has an attractive rural location and is less than two hours flying time from London, while the major Scottish cities of Glasgow, Edinburgh and Dundee are all within an hour's drive.

This course is aimed for experienced engineers seeking a short theory based course.
