The background noise is the vibrating mechanism inside the standby altimeter instrument. (altimeter vibrator). This to ensure a more accurate readout of this instrument. It makes the needle go to the most "relaxed" position . Same effect as if you tap your finger to the glass to make sute the needle is not stucked.Instead they made this "hammer" do it for you. Very often pilots pull the CB of this vibrator to get rid of the noise, but they forget to push it in after landing.
N1 is the rotation of the fan in front of the engine, the one you can see when you look straight at the front of the engine. It is connected to a shaft that runs through the engine and is turned by a turbine at the aft of the engine.
N2 is the rotation speed of the central core. The turbine immediately aft of the burner can receives the highest velocity airflow and turns a turbine that is hidden behind the N1 fan where we can't see it.
Just what i was looking for. Thank you so much for uploading this video

great video reminds me of when I use to fly the old 737's with Qantas, now on the 747-400's the rest is history

In order to shut down you just cut off the fuel by using the cut off switches on the pedestal or you must do something else before?

Dear All,
I have some questions about psychology:
(1) Why do we love flying and aeroplanes?
(2) Why do we so curious about the design jet engines?
(3) Why do we so curious to know how jet engines operate, especially children?
(4) Why so we like to design and to build new-creative jet engines?
(5) Why some of us want to design and to build home-made jet engine at our backyard?
THANK YOU IN ADVANCE for your creative ideas and brainstorm!!! :)

Could anyone please tell me where does the background noise come from?

26% N2? I always thought it was 20%.

@gokumalo I'm not 100% sure, but the 20% apply to the Next-Generation 737...

silly question you might think, but the read out within those N1 and N2 dials.. are they digital or spinning mechanical dials?
johnnyjohn2005 2 years ago
Those lighting numbers are digitals. The pointer is mechanical.
It looks like spinning dials but its all digital lights.

N1 & N2 is used to determine the engines shaft/s RPM. CFM56 engines have 2 shafts that spin independantly of each other.
N1 is the fan RPM
N2 is the Core RPM
