From what I've heard the chopper instrument check (HTs) is a total kick in the nuts. Briefs lasting 4 hours or more, etc. WTF?
First, is this true, or just myth and urban legend?
I think it's a little bit of both. My pre-check (RI-17) the brief lasted for a whopping 30 minutes. My check ride (RI-18X) the brief lasted for about an hour and a half. I've known guys whose brief lasted upwards of 2 1/2 hours, but I haven't heard of one lasting four hours. It is a kick in the nuts, covering a ridiculuous amount of OPNAV 3710, FAR/AIM, plus all the pubs.
Second, if true, why such an emphasis? After advanced I've seen chopper dudes go to extraordinary lengths to avoid flying IFR. They "never" do it. Hence the phrase "I follow Roads" etc.
This seems to follow to the fleet. My roomate on my last float spent LOTS of time debriefing inst checks and writing elaborate gradesheets. Why?
In the jet world it's just not a big deal. It's an easy flight and minimal debrief. Some standard blurb on the required forms and off you go.
There's a number of different reasons why we avoid flying IFR like we avoid a toothless, HIV-positive hooker.
First, a helo isn't the most stable of IFR platforms. Yes, they have AFCS to help stablilize it - but it's still not great. Also - no autopilot to reduce the workload (well, you could call a 2P an autopilot). And if your AFCS fails when you're in the goo? It's like flying a TH-57B again. Only now, you can refer to the TH-57B as a "stable instrument platform". It's that bad. I once had a CO turn off my AFCS during my instrument check (and I was actually in the goo), during a TACAN point to point. I ended up 7 miles away from the intersection I was aiming for. The ball just isn't designed for the sweet amount of yaw you get when you're AFCS off.
Second, most fleet helos (as mentioned previously) only have TACAN. Our precision approaches include the mighty PAR. So, in some areas of the country (like between Dayton, OH and Morgantown, WV) we can't LEGALLY fly on the airways. Weather sucked leaving Dayton, and only the 53's could fly to Morgantown (because they have a VOR/ILS). We had to wait for the weather to break because there weren't enough VORTACs between the two.
Finally, I think the biggest reason we avoid IFR like we avoid a romantic night with a Thai ladyboy is because we don't have an ejection seat. We're riding Mr. Toad's wild ride to the end. If I'm in the goo and have to autorotate - I have no idea how it's going to turn out. I could be autorotating into buildings, trees, powerlines, towers, or an open field. I'd rather have a fighting chance of surviving the autorotation by being able to see what I'm autorotating towards. Because I'm in the goo, I don't know that if I turn 15 degrees to the right I'm pointing at an empty field. Instead, I'm aiming straight for a building. I'd rather fly under the weather and see the obstacles.
I think these reasons are why IFR is viewed as almost an EP in a helicopter, and hence the reason for the long and detailed briefs. We can do it, but it's not our first choice. And when we do it, we have to be on our game.
