Speedbrake armed annunciator 737

[hercules123]

Hallo Bobby Riders,

 

ist es korrekt, dass der Speedbrake armed Annunciator auch leuchtet, wenn der Level hinter der armed Position steht und die Speedbrake dann auch ausfahren beim Touchdown?

 

Mir hinter meine ich in Richtung up

 

Best Regards/ Beste Grüße

Thomas
