I am working on building hours for my commercial and intend on taking advantage of the 50 hours allowed in FTDs part 61. I have a few question that maybe you all could answer. I used an AATD and a MFD CAT IV at DCA. They logged it a FTD but are they considered FTDs and do they count towards the 50 hours? I also did most of the time before I pass my instrument check ride. Will the FTD time I did before the instrument apply to the commercial? And just your opinion, I only need 20 hours till I start commercial training do you feel it is beneficial for me to do most of it in the sim or a real airplane? FTD would be most beneficial financially but flying a real airplane will defiantly be more educationally beneficial and more fun! Thanks.
