yonyz Posted March 5, 2011 Posted March 5, 2011 Hi, I'm flying the On The Other Side mission, and in the area where the mountains are all iced, I simply can't get forward speed. I'm pretty much stuck in the air. I have turned on Rotor De-Ice, and the only way to gain a speed of more than 5kmph is by raising the collective all the way up, which triggers some beeping, and afterward I lose power to the Shkval. What can I do to fly such areas of low temperature and high altitude?
Distiler Posted March 5, 2011 Posted March 5, 2011 Go around 120-130 km/h and start climbing way before you reach the mountain ladder. At this speed you climb faster than at any other speed. AMD Ryzen 1400 // 16 GB DDR4 2933Mhz // Nvidia 1060 6GB // W10 64bit // Microsoft Sidewinder Precision 2
yonyz Posted March 5, 2011 Author Posted March 5, 2011 I have to admit, this mission's route now seems impossible to fly, but in my previous attempt at this mission I had absolutely no issues getting to the hostile area. The funny thing is that in both occasions I used the autopilot ROUTE mode. I'm attaching the track file. It's about 20 minutes into the flight when the problems begin, so I hope it's possible to fast forward tracks.High iced mountains.trk
Distiler Posted March 5, 2011 Posted March 5, 2011 I saw it. As I said, you need to climb at around 120-130km/h, so start climbing waaay before you do it or will be forced to slowdown or smash into the mountain. The helicopter doesen't climb at 50km/h as fast as at 120-130 (it has wings = lift) Also, you have rotor anti ice activated, but you forgot engine anti ice (but that was not the problem, because you smash into the mountain before any engine problem).

yonyz Posted March 5, 2011 Author Posted March 5, 2011 Did I really smash into the mountain? From my perspective it looked like I exploded mid-air. Do I need to turn all anti-icing systems, including pitot icing? I believe I should, because I lost airspeed indication when I was up on those mountains, and got it back as soon as I left the icy mountains.
effte Posted March 5, 2011 Posted March 5, 2011 The stub wings do very little as far as creating lift goes. However, a rotor generates significantly more lift with forward airspeed than when slow or in a hover. Google "translational lift". In fact, heavy choppers may not be able to hover at all but will need to perform rolling takeoffs to get off the ground at all - that's how much translational lift adds. Cold weather helps you by increasing the performance of the helicopter. The killer is hot and high. Always turn on pitot heat if you even suspect you may go near icing conditions. Anti-ice in general will steal some performance, but you only have to have a hint of ice on the blades for performance to go down a lot more.

Henchman14 Posted March 5, 2011 Posted March 5, 2011 (edited) Well, if your pitot is iced over, you may be going a lot faster than 5 km/h. The pitot is your airspeed measurement instrument, among other things. Edited March 5, 2011 by Henchman14
yonyz Posted March 5, 2011 Author Posted March 5, 2011 No Henchman14, I SAW the airspeed indicator showing 5 kmph, and that was before it stopped working.
Distiler Posted March 5, 2011 Posted March 5, 2011 When I watched the reply I used external view, you where going around 50km/h, no way to get higher at such altitude and slow speed. As said, you need to go faster if you want to climb higher, and start to climb sooner too. AMD Ryzen 1400 // 16 GB DDR4 2933Mhz // Nvidia 1060 6GB // W10 64bit // Microsoft Sidewinder Precision 2
yonyz Posted March 6, 2011 Author Posted March 6, 2011 OK then. I will try it again tomorrow after I pick up my PS3 Eye camera and try it with FaceTrackNoIR. :)
