AWOS vs ASOS
Im lookinga t the commercial PTS and it says " Exibit knowledge of the elements of..." and then AWOS ASOS and ATIS is in there. My question is what exactly do we have to know about AWOS and ASOS, I cant really figure out the differences between the two except for the different types of AWOS's such as AWOS-A, AWOS-1 and the fact that some are owned by the FAA and others are locally owned. Am I missing something here or is it important I know all the extreme details of it to get thru the oral?
Thanks
