yourfavoriteweapon Posted December 11, 2012 Report Share Posted December 11, 2012 Currently at the safety course, just completed the first day. Looks like it'll be an interesting few days! Heard flying at sea level is different, and the low rotor rpm horn is constantly on out here. Anyone else here at the course this week? Looking to grab a few dinners and hear about the industry, current work, interesting stories etc. Thanks! Quote Link to comment Share on other sites More sharing options...
RagMan Posted December 11, 2012 Report Share Posted December 11, 2012 The low rpm horn is constantly on? Are you guys packing weight, or is the DA that high down there? Have a blast with it! Quote Link to comment Share on other sites More sharing options...
Lindsey Posted December 11, 2012 Report Share Posted December 11, 2012 Where did you hear that the low rotor rpm horn is constantly on? You're on your first day so you haven't flown yet... Quote Link to comment Share on other sites More sharing options...
yourfavoriteweapon Posted December 11, 2012 Author Report Share Posted December 11, 2012 Right, we havent flown yet. I had a few friends who went recently and they mentioned they heard the horn/light more often than they wanted to. I think we have just been conditioned to take immidiate corrective action when flying at higher altitudes. Here at sea level you may have more time to respond to low rotor rpm recognition & recover? A few guys said its like flying in jello out here. A few more days and I think I'll have my answer. Should be a blast, thanks! Quote Link to comment Share on other sites More sharing options...
ridethisbike Posted December 11, 2012 Report Share Posted December 11, 2012 I've heard that they do that as well: keep the horn on. Not because of DA or weight, but just because... Quote Link to comment Share on other sites More sharing options...
pilot#476398 Posted December 11, 2012 Report Share Posted December 11, 2012 I've been to the course a few times, and I have no idea what you guys are talking about! If you're hearing a horn all the time, check with your doctor, it might be tennitus? I would expect the horn to come on a lot in the mountains,...or if you're flying a CBi, but not a Robbie at sea level! Quote Link to comment Share on other sites More sharing options...
Aaaron16 Posted December 11, 2012 Report Share Posted December 11, 2012 You only have a short period to fly, so naturally most of the time will be spent on autos, low RPM recovery, energy management, and other maneuvers where RRPM < 97%.

I guess if you've never done max-glide, or minimum-rate of descent, you might think the horn is on "a lot"?,...but with those maneuvers you should be expecting it to come on!? Thus it shouldn't surprise, or bother you? Quote Link to comment Share on other sites More sharing options...
Aaaron16 Posted December 11, 2012 Report Share Posted December 11, 2012 ^ that's what I was saying. Quote Link to comment Share on other sites More sharing options...
DieselBoy Posted December 11, 2012 Report Share Posted December 11, 2012 (edited) lol they don't just keep the horn on. It's during the autos, keep in mind your green and yellow rotor tach arcs are 90% - 110% and you can operate in that area if you know what you're doing.

A lot more room to play with them at sea level than higher da. Thanks for all the input. Quote Link to comment Share on other sites More sharing options...

If you're doing extended glide autos or minimum rate of descent autos, they both require 90% Rotor RPM, so trust me the horn will be on! 1 Quote Link to comment Share on other sites More sharing options...

Trust me, autos, 90%, that's what I said! Yes the horn will be on any tme below 97%, everyone knows that, but the instructors don't just "Keep the horn on" as someone else stated!

eagle5 Posted December 13, 2012 Report Share Posted December 13, 2012 When I was there the cfi had me roll the thottle down to 97% and fly around for a bit to see how the helicopter felt. The horn (of course) was on constantly! Perhaps that's what they are refering to? Quote Link to comment Share on other sites More sharing options...
schrocks01` Posted December 13, 2012 Report Share Posted December 13, 2012 When I attended, we did the same thing. The instructor wanted me to understand that the horn doesn't mean that we're going to fall out of the sky. We did a lot of work focusing on low RPM recognition and recovery. I did mine in the R22, BTW. Not sure, but probably not as focused on the low RPM issue with the R44. Quote Link to comment Share on other sites More sharing options...
