blue_six Posted February 28, 2017 Share Posted February 28, 2017 The RW Spit MkIX Pilot's Notes have a note in the "Climbing" section cautioning that leaving the air intake filter control in the filter in operation (forward) position reduces the full throttle height considerably. I'm not seeing any performance penalty from failing to move the lever to the normal (aft) position after takeoff, either in full throttle height or in straight and level max airspeed. Can anyone else confirm? I'd expect to see this modeled, eventually - perhaps we're just not there yet? Link to comment Share on other sites More sharing options...
Captain Orso Posted February 28, 2017 Share Posted February 28, 2017 It's an air filter. You only need it on the ground. Is should be on from before you start the engine, until after you have taken off. And, before you land turn it one againg. When you hit the wrong button on take-off System Specs.

The point I am making is that if the filter is mistakenly left on, there should be a performance penalty due to the associated restriction on the intake. I don't see this modeled in the sim, and think it should be. Just as hypoxia is modeled when you forget to turn on your oxygen, there should be consequences to this pilot error.

Sokol1_br Posted February 28, 2017 Share Posted February 28, 2017 The reason for turn on air filter - avoid ground dust to damage engine is modeled? Link to comment Share on other sites More sharing options...
blue_six Posted March 1, 2017 Author Share Posted March 1, 2017 The reason for turn on air filter - avoid ground dust to damage engine is modeled? I don't know, Sokol1_br, and hadn't even considered this possibility. I am more likely to forget to move the lever to "normal" after takeoff than to move it to "filter in operation" prior to landing. And unless the dust damage during and after landing was immediate and serious, or was modeled to persist and accumulate over several sorties, it seems unlikely to be an issue for me at least - at this stage, my poor Spitty seldom survives more than three or four trips before being written off in a landing accident...

Art-J Posted March 1, 2017 Share Posted March 1, 2017 I think I recall filter on having some adverse performance effects in the Mustang, so maybe they haven't been implemented in the Spit yet. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

Holbeach Posted March 1, 2017 Share Posted March 1, 2017 (edited) The RW Spit MkIX Pilot's Notes have a note in the "Climbing" section cautioning that leaving the air intake filter control in the filter in operation (forward) position reduces the full throttle height considerably.

Operating at max continuous sea level speed of 289kts, operating the filter made no difference, therefore it is not implemented. Edited March 1, 2017 by Holbeach changed picture.

Thanks for confirming that, Holbeach. Hopefully the devs plan to implement this in the future. Link to comment Share on other sites More sharing options...
