I can validate the use of all of them, when a 3rd party developer designs procedures, the various departments put the procedures into the respective design tools to review the design.
Different departments between AVN, and the numerous AFS use the software I described, but for different uses.
Within the FAA, Procedures are designed, then routed to numerous departments for review and evaluation.
AFS-460/420 use RNAV-Pro is used for DME coverage evaluations of procedures and diverse departure design.
AFS-460/420 also use SAAR-Pro is used to evaluate and design RNP procedures along with TARGETS.
TARGETS is used to design procedures, locate and evaluate waypoints, and evaluate the obstacles on the ARAC cycles.
Currently, AVN is also using IPDS by MDA as the main procedure design tool, but this is being implemented in several stages...so I am not sure which departments have the software...
I would agree, TARGETS is an abomination, and the main reason we still have to submit 8260 forms.... and IPDS isnt any better...
