I've noticed that many of the older DC-9s were originally equipped with oscillating strobes that didn't have the on/off effect of modern strobes. You can see the effect in this video.
All DC-9s I've seen for FS 2004 have the conventional style strobes. Is there a limitation in FS that prevents the effect as seen in the video?

Someone once raised a similar question in relation to the B727's we host here too ;D The answer to that query was .... some of these aircraft were equipped with that type of wing tip strobe lighting whilst others weren't. The same might apply to the DC9's too   If Nick hasn't applied one, or another, form of wing tip strobe lighting .... then .... there will be a "good reason" for that !  Including it, if not already epresented, would likely require significant LIGHTING section edits to AIRCRAFT.CFG files in order for this effect to be represented .... and which probably wouldn't be appropriate for all DC9 aircraft anyway. Probably best we leave things as they currently are .... me thinks ! Mark C AKL/NZ |

These are not strobes. These are simply mirrors installed behind the navigation and recognition lights to make them appear to flash. It is completely possible to create this effect in FlightSim, however it requires a different effect to be created that gives the effect. Milton Shupe has this effect on his Aero Commander series of aircraft if you want to see an example.
Prior to the introduction of the Wingtip Strobe (and its later requirement by regulation), some airlines chose this option for DC-8s, DC-9s, DC-10s, 707s, 727s, and even a few 737s. However, the lights were actually removed from the regulations in the 1970's and are only allowed to be "grandfathered" on aircraft. However, under the "grandfather" clause, once a unit fails it cannot be replaced and all other units on the aircraft have to be deactivated.
The reason that this fell out of favor is simple - it removed the ability for pilots at night to be able to clearly, consistently, and rapidly determine what he was looking at since the reference to the constant red, green, or white light was lost.

Thanks for your explanation! I'm going to check out Milton Shupe's Aero commander to see it for myself. |

BTW, I realized that I didn't put it in the original post, but the mirrors are turned by a small motor to create the effect. I will try to find the picture I thought I had of the installation on a 727. |
