Richard, google are not designing their own system - they are following the TSO C199 which is put out by the FAA.
Please read this and you will understand what aviation manufacturers have to endure - painful but it ensures we are all on the same playing field when it comes to compatibility. As per my previous posts, TABS was put out because of a need to have low cost CAS systems.
