A1 being en route, terminal and non-precision approach-certified (A2) drops the approach ability. Those TSO's have specific installed requirements and tests. You simply can't meet those requirements with a portable unit, RAIM (Receiver Autonomous Integrity Monitoring) is one area where portables have issues among others.Even the remote altimeter requires wiring as does the required remote display head (CDI) and soon you have so many wires that HAVE TO CONNECT there is no easy quick way to have the unit still portable.You can read the TSO atWith the costs of getting a unit approved under those orders, which is not insignificant, there are no portables that have done it nor is there a good reason for the manufacturer to do it and accept the liability involved.
