Why Direct Approach?

Procedure design is a very technical field, and requires special training. It also requires years of experience to be able to provide your site with an optimum design.

Before you contract a procedure designer, ask the following:

  • Have they been trained by an accredited agency?
  • Is the training recognized by the local Civil Aviation Authority?
  • Do they have experience in the type of operations you need?
  • Are they covered by a professional liability policy?

At Direct Approach, we only use the most experienced procedure designers, and all our personnel have received properly recognized training in:

  • TP308

We are recognized experts in RNAV (GNSS), high altitude & mountainous terrain, and rotary wing procedures.

Our designers have created and published over 100 approaches and departures in:

  • North America
  • Australia
  • Africa
  • South America
  • Middle east (Saudi Arabia)

With Direct Approach you can be assured that you get only the most experienced and fully trained technical experts. Let us help you increase your accessibility, safety, and operational efficiency with an IFR GPS or conventional approach and departure!
