Hi folks,

  

  

The Weekend’s coming, guess you will bring your drones out and enjoy your flight. Before it coming, let’s do a little quiz to test yourself, do you very clear about what does it means while a drone lights flashing?

  

  

Here you go!

  

  

1.       What does “Fast alternating red and yellow flashing” means?

2.       What does “Alternate yellow and green flashing” means?

3.       What do “Alternating red, green and yellow flashes” mean?

4.       Is that normal for the drone headlight to appear red after the drone is started?

5.       What does it mean when the status of the drone indicates that the yellow light fast flashes?

6.       What does it mean when the status of the drone indicates that the red flashes?

7.       During the flight of the drone, what does “fast red flashing” means?

  

The quiz above cover the consumer and professional drones (Mavic series/ Phantom series/ Inspire series/ Spark).

  

  

Before 19:00, 15th April (UTC+8), 2019, share your answers in this thread, we will pick up to 5 correct answer users to send each of them 600 points!

Many people have wrong the No.4 question.

Actually, it is normal for the drone headlight to appear red after the drone is started.

Nice one

1.       What does “Fast alternating red and yellow flashing” means? : Compass Calibration Required
  
2.       What does “Alternate yellow and green flashing” means? : Warming Up
  
3.       What do “Alternating red, green and yellow flashes” means? : Turning on and self diagnostic testing
  
4.       Is that normal for the drone headlight to appear red after the drone is started? : Solid red means critical error.
  
5.       What does it mean when the status of the drone indicates that the yellow light fast flashes? : Remote controller signal lost
  
6.       What does it mean when the status of the drone indicates that the red flashes? : that depends on the speed of the flash. Slow = Low battery, Fast = critical low battery, normal = IMU error

Maybe the forum needs a way to hide other's replies to a thread to make these kind of contests where you need to answer something work better

Yes, we will make it be possible soon!

Nice topic! Will join soon.

Seems like a good addition to the (already nice) Forum!

Copy and paste ?

Just luck

1.  Compass Calibration Required
  
2.  Warming Up
  
3.  Turning on and self diagnostic testing
  
4.  Critical error.
  
5.  Remote controller signal lost
  
6.  IMU error
  
7.  Critical low battery

1.       Compass Calibration needed
  
2.       Warming Up
  
3.      Turning on, self diagnostics
  
4.       if solid red, that means critical error
  
5.       Remote controller signal lost  (happened to me once)
  
6.       That all depends on the speed of the flash. If it is slower, then the battery is low, if it is fast  then the battery is very low, if it is normal, then it is an IMU error
7.       Critical low battery. (as said in the above answer)

Agree with that, great feature for quiz like this

With so many ties, how do you choose?

Nice one

thanks

1.       What does “Fast alternating red and yellow flashing” means?
Compass calibration required
  
2.       What does “Alternate yellow and green flashing” means?
Warming up

3.       What do “Alternating red, green and yellow flashes” means?
Turning on and self diagnostic testing
  
4.       Is that normal for the drone headlight to appear red after the drone is started?
The two front headlights are fine if red as used for visual orientation but a solid rear LED's mean that a critical error has happened which is not normal and the drone should not be flown
  
5.       What does it mean when the status of the drone indicates that the yellow light fast flashes?
The remote controller signal has been lost
  
6.       What does it mean when the status of the drone indicates that the red flashes?
a. Slowly - low battery
b. quickly - critical low battery
c. normal blinking speed - IMU error
  
7.       During the flight of the drone, what does “fast red flashing” means?
Critical low battery warning. The drone has typically reached 10% battery level (or whatever the pilot has set in the app if higher) and the drone will begin to land without any input from the pilot. You can increase the throttle to maintain altitude as you safely land the drone. However, this should be avoided at all times.

4.       Is that normal for the drone headlight to appear red after the drone is started?

Reading exactly     Headlight is at the front.

That is  normal for the drone headlight to appear red after the drone is started.

I agree with most post on the answers but I have a doubt or note some discrepancy:

So I assuming it varies from one drone model to another? I only have had a Mavic 2 Pro.

But according to manual warming up is yellow blinking and not yellow and green. According to Mavic 2 Pro and Zoom User Manual V1.6 page 14.

Question 6 definitely several answers as it does not indicate if fast or slow. So I think that it was a good reply from @FuZZyPiLOT with the different possibilities.

But once again, I have no experience with other DJI drones, so not sure if that is the reason or something change after a firmware update.

So is there really a yellow and green status? Appreciate comments.
