Phenom strobe lights

Recommended Posts

Hello,

 

have a question about the strobe lights, are these correct modeled ?

 

see this clip :

 

http://www.youtube.com/watch?v=TRoMAQ59Brw

 

why is it not modeled in the sim like in the videoclip ?

 

Carenado said they could model it like that but the strobes do not flash simultaneous appearing to them on the real aircraft.

 

kind regards

Hi there,

 

I don't think the flashing light on the video is a strobe light, it looks more like a flashing nav light but the wrong color for that side of the aircraft.  At least it looks wrong on my monitor.  At any rate the light is not displaying the properties of a strobe light i.e. a flash of high energy light that has a duration of a few milliseconds.  So, IMO the Carenado modeled strobes are correct.

 

Hope that helps some.

 

Bill

That looks more like a pulse light system.

To me, it looks like instead of strobes, these aircraft have LED anti-collision lights.

Good point. They probably are LED.  I didn't know they were using LED's for anti-collision lights but I looked it up and the Phenom does apparently have  them.  I don't know whether strobes are also available on the Phenom or not.  I would hope so, as the strobes are much more effective based upon what I am seeing in the two videos.

LED anticollision lights (strobes) are FAR more effective than traditional strobes. The B787 has them and the difference is clear when you see it among other airliners at night.

 

Many new aircraft (including the Phenom) are coming with LED's as standard now, as they're brighter and last longer.

To me, it seems like we have come full circle with anti-collision lights.  I remember when anti-collision lights were flashing incandescent bulbs, either the navigation lights or clear lights were used.  Then came the strobes.  Now we have LED anti-collision light that blink on and off as well as LED navigation light systems.

The flashing lights in the videos do not appear to be emitting high energy short duration blasts of light consistent with the properties of strobe lights.  But, ok, you win.  They must be strobes.  Pretty wimpy looking though. :unsure:

Hi Stans,

I think you are correct.  Apparently we have come full circle.  I remember the old rotating beacons which consisted of a mirror rotating around an incandescent bulb.  Then Cessna came out with what they called "Omni Flash" beacons.  They were just what you describe, a bulb mounted on the tail with a red lens that slowly blinked on and off.  They were not as effective as the rotating beacons though.  Then came strobes which changed everything.  Now, if the subject videos are representative of the present state of anti-collision lights, we are back to blinking lights.

All strobes look wimpy under bright sunlight.

 

 

Compare this (skip to 01:00 minute mark):

 

to this (skip to 02:00 minute mark):

 

 

I've seen the LED's side by side with traditional strobes (both on airliners, as well as the Phenom). There is no contest between them. You can see the LED's very clearly from much further away.

Are the two videos that the OP referenced the "more effective" LED strobes that you are referring to?  Or are they something different?

Ok, I guess "strobe" doesn't mean what it used to.  Times are changing.  Thank you for the lesson.
