masonator Posted November 25, 2008 Posted November 25, 2008 Hi all. Does anybody have a problem whereby autohover goes on the fritz about 1 or 2 feet off of the ground? I'm perfectly lined up, hovering dead center with the little box right in the middle of the circle, and so I begin to pull power off. Right before I touch down, the aircraft begins to bank or pitch pretty aggressively. The result is a horrible landing at best, a mild crash at worst! It's very infuriating! Mase
GGTharos Posted November 25, 2008 Posted November 25, 2008 Read the manual. [sIGPIC][/sIGPIC] Reminder: SAM = Speed Bump :D I used to play flight sims like you, but then I took a slammer to the knee - Yoda

Mase Its called ground effect. You're hovering in the turbulence caused by your own rotor wash bouncing off the ground and coming back at you. Very close to the ground is not a safe place for helicopters to hover.

takamba Posted November 25, 2008 Posted November 25, 2008 To hover in ground effect is like walking on eggs :smilewink: DCS Rafale - please :thumbup:
Amraam Posted November 25, 2008 Posted November 25, 2008 To hover in ground effect is like walking on eggs :smilewink: More like trying to balance eggs on top of eachother. I know what ground effect is like on takeoff just from my RC Heli experience :D [sIGPIC][/sIGPIC] | Intel E6750 @3.2Ghz | 2GB OCZ PC2-6400 RAM | XFX 680i SLI | BFG GTX260 216SP | Western Digital 3200AAKS 320GB SATA II HDD | | Seagate 320GB 16MB SATA II HDD | Creative X-Fi Fatal1ty Soundcard | Samsung 245B 24" TFT Monitor | | Logitech Z-5400 Digital THX 5.1 speakers | Logitech G15 | Logitech MX1000 | TM Cougar #27955 | TrackIR 3 Pro
takamba Posted November 25, 2008 Posted November 25, 2008 I know the ground effect as well, I do also have some experience with R/C helicopters, but this is years ago. Was a funny but expensive time. DCS Rafale - please :thumbup:
Tango Posted November 25, 2008 Posted November 25, 2008 Hi, I've found that it doesn't like to land on the terrain. Buildings/roads are OK, but generally anywhere else and it rolls/shakes violently. :huh: Best regards, Tango.
masonator Posted November 25, 2008 Author Posted November 25, 2008 Got it. Thanks all! GGTharos: I'm reading the manual, but it's long and I haven't got there yet.
Boberro Posted November 25, 2008 Posted November 25, 2008 Read the manual. :megalol: Sry for OT. Reminder: Fighter pilots make movies. Bomber pilots make... HISTORY! :D | Also to be remembered: FRENCH TANKS HAVE ONE GEAR FORWARD AND FIVE BACKWARD :D ಠ_ಠ ツ
Zorrin Posted November 25, 2008 Posted November 25, 2008 Its called ground effect. You're hovering in the turbulence caused by your own rotor wash bouncing off the ground and coming back at you. Very close to the ground is not a safe place for helicopters to hover. Actually, hovering in ground effect is one of the safest places to hover... You require less power to hover than when you are out of ground effect. This cushion of air actually helps support the aircraft. It also means you have a lot less distance to fall if you have an engine failure and need to autorotate... The same principle applies to fixed-wing aircraft, in effect, extra lift is generated. Particularly useful for soft and short field take offs. You can also accelerate quicker in ground effect too... Eagles may soar, but weasels don't get sucked into jet engines.
Peyoteros Posted November 25, 2008 Posted November 25, 2008 Noone said it will be easy, takes a big deal of time to crack on. Would be borring if you could jump on and do everything in no time. Flying, reading manuals it's a must. Autohover does not work below 4 meters. "Eagle Dynamics" - simulating human madness since 1991 [sIGPIC][/sIGPIC] ۞ ۞
Draco Posted November 25, 2008 Posted November 25, 2008 As Zorrin Said In Ground Effect is a good place to be. As far as turbulence and controllability there's really no difference between hovering IGE and OGE. For those of us who fly Helicopters without wheels, we spend a good bit of time hovering about in ground effect. It's no different, just requires less collective and besides going higher starts to put you in the shaded area of the Height/Velocity Diagram and that's a place you just want to stay away from.
