First, I agree with the previous posters. I would also say lazy is not the proper description. One of the biggest problems with TAA is the lack of standardization. Secondarily; complexity, currency issues and transition to them are other significant issues. However standardization would go a long way towards solving the secondary issues. I am all for progress and inovation, however I hold the FAA responsible for not having or exercising the foresight to prevent this. There is one more chance to nip this issue in the bud. That is to get this under control prior to the full scale rollout of ADS B. Avionics manufacturers are now no different than those making Cell phones. Just think about getting used to a new phone; and do we understand and are able to make use of all its features, to operate the phone proficiently and competently... I know several GA pilots that have stopped flying due to the proliferation of TAA, and the negative issues associated with these aircraft, combined with accessability issues to descent steam gauge models. It takes the average pilot 15 to 20 Hrs. to make the transition just to fly VFR. It takes over a 100 to become safe and proficient to operate IFR; and I'm not talking enough ability to pass an instrument checkride, I mean proficient. This is rediculous and has become another death nail in GA. Younger pilots might argue this point, though from another perspective and not considering the big picture. Checking someone out in an unfamiliar aircraft used to be about flying the aircraft; it's now about flying the radios... Same thing with a trip to Flight Safety/Simuflite, Etc.; it's all about the box. Due to the limited time instructors have to spend with students, it is no wonder we still have unacceptable accident and incident rates and that LOC events are on the rise. When we have instructors highlighting their abilities with TAA and even writing books on the subject, that should be an indication of an issue right there. Nothing against that and they are performing a valuable service, however it's still an indication of a major issue. I don't think going backwards is the answer though it is certainly time to pause for some reassessment...
