Arm out the Window
Going to 150 hr for CPL doesn't sound much till you have to put your hand in your pocket to pay for it.
Doing the bi annual in a R44 isn't a drama if you have that type and now fly say a ec120 as I do, but there are a couple of issues. Over the next 10 years I will be checked out (PPL) 5 times , all in a 44 that I only fly for this purpose. Doesn't help me much in the 120. Do it in the 120 I hear you say, well who is going to do it? I can't find anyone left. How about the MD900; MD600, ec135 etc there just are not the instructors able to do them. I imagine there are enough in 44's, but wouldn't it actually achieve something to do it in your own aircraft.
