: I notice on the JU88 video the KA32 taxis all over the airfield before taking off. On the helicopter flights I've made from commercial airports, the same thing happened. Any idea why this is done? The Scilly Isles heli from penzance does the same, and it takes of (all be it rather steeply) like a fixed wing aircraft. I assumed this was to save fuel. In the JU-88 vid, it looked like the KA-32 was just taxying to the helipad for departure - that's common practice at my home airport where there's a lot of helicopter activity. Helps ATC coordinate while optimising helicopter operations a little more than pretending to be a f/w. As for penzance - I haven't been there, but if they're close to Max Weight, they may prefer to use the runway for a bit of a rolling takeoff. Also, some ATCers don't really know (or want to know) how to deal with helicopters so they force them to act like a f/w around their airfield - this is generally also the case under IFR regardless. Some or perhaps all of those reasons might be it. toady. |

happens to me, too. AFAIK, the Mediaplayer is in version 7 for the MAC and in version 9 for the PC. don't know what type of carbonized version they Windows Mediaplayer 9.0.0 is available for Mac OS X at http://www.microsoft.com/mac/otherpr...aspx?pid=windo wsmedia I use it rarely, only if something with the wmv9 codec comes my way. It's quite buggy, but hey it's from M$... ;-) The videos are cool, just the music's not really my cup of tea... ;-) Cheers, Jens -- I don't accept any emails right now. Usenet replys only. |

What prevents those contra-rotating rotors from touching? The blades are rigid, far apart , but, most importantly, they are kept about the same distance from each other by the centrifugal force. Sometime they do touch, however. This happened with the Ka-50 when the pilot exceeded the maximum G load during testing. Ka-50 crashed and the pilot had no time to eject. Since then Kamov use a different material for the blades and moved them further apart. -- Regards, Venik Visit my site: http://www.aeronautics.ru If you need to e-mail me, please use the following subject line: ?Subject=Newsgr0ups_resp0 nse |
