| Feb 15, 2016 at 20:08 | comment | added | Todd Wilcox | Another possibility is that leading edges have to be periodically replaced, and it's cheaper to keep the polished aluminum look rather than have custom colors applied for what is essentially a consumable part. Frankly, I suspect erosion is a likely factor in the answer to your question about engine fairings. | |
| Feb 15, 2016 at 20:05 | comment | added | Todd Wilcox | Looks like I might be on to something but not quite right. "Leading edge erosion" is a problem. One solution appears to be applying erosion resistant films to leading edges. I wouldn't be surprised if the films have to be replaced from time to time, and that application and removal of the films might be best done on bare metal rather than painted metal. 3M's page on leading edge films | |
| Feb 15, 2016 at 20:00 | comment | added | Todd Wilcox | I always assumed a lot of leading edges were left unpainted on all kinds of aircraft because of the paint frequently wearing off in those places. Better to leave it neatly unpainted than to have unsightly chips that have to be frequently touched up. | |

| Feb 13, 2016 at 19:09 | comment | added | Porcupine911 | The 787 does not have heated empennage leading edges. The anti-ice is only on some of the wing slats. This 787-9 has the Hybrid Laminar Flow Control system integrated into the tailplane leading edges. | |

| Feb 13, 2016 at 17:10 | comment | added | user13197 | On this video: youtube.com/watch?v=Q_NjnaUKcIk (minute 16:23-16:55) a man is putting a tube on the leading edge of the wing and then covers it with a bare metal. Perhaps the same happens on the leading edge of horizontal and vetical stabilizers. | |

improve title, spell check

| Feb 11, 2016 at 23:00 | comment | added | J W | @JanHudec As I'm sure you know, many aircraft have no anti-icing systems at all, or have only pitot probe heat. I don't think you meant to include these types in your statement, but I just wanted to make sure that is clear to others. | |
| Feb 11, 2016 at 22:29 | comment | added | Lnafziger | @JanHudec Not all aircraft have heated horizontal or vertical stabilizers (for instance, the Learjets only have the horizontal stabilizer heated (electrically), and the Falcons don't heat either one at all). | |
| Feb 11, 2016 at 22:26 | comment | added | fooot | @JanHudec perhaps there is an option to paint them, with a reduction in icing allowances. | |
| Feb 11, 2016 at 21:47 | comment | added | Ron Beyer | Yes, it uses a heated edge system designed to melt the boundary layer of ice on leading edge surfaces. The system is designed by GKN. | |
