The N1 Gizmo

Post by jaeger52 » Thu Aug 12, 2010 10:10 pm

Okay here's your chance to make me feel dumb and dumber. And with this crowd, that shouldn't be hard to do. When flying the big rigs I can't help but notice the N1 Gizmo on the main panel. O:)

Q1) What is it for?
Q2) When should it be turned on/off?

Well hell! I could've figured that out for my own self if only I'd of pushed that danged button once or twice! And now I'm glad I didn't becuz I don't take no sugar in my coffee! And I sure as tootin' don't stick out my pinky finger neither when I'm havin' my cuppa schmo! I'm a two fisted kind of joe-drinker and always have been!

As for pushing buttons all willy-nilly, you should know yourself by now how things go when you stick out your finger and start pushing buttons! Now (x) times that by square roots and let me know what you come up with?

Now gol-dang it, help me out here for the criminently! Is it an "upside down" button or not? :evil:

I'm serious!

Bruce:

I threw your question at one of my CAP pilots from today who has been flying for about 30 years. He advised me that N1 is sort of like a boost of high power. When I just performed a Google search on "N1 Airspeed" I kept reading references to X percent of N1. Perhaps if you also do some Google searches, you may find similar answers. 8) 8)
I AM NOT A PILOT. I JUST LOVE AVIATION.

N1 Button
This button controls activation of the THRUST N1 function of the autothrottle. When the button’s internal LED is lit, the THRUST N1 mode is engaged.

N1 BUTTON

This is an LED lit push button. Operation is push for on, push for off. N1 controls the speed of the engine outer compression fan e.g thrust

When the N1 button is activate, the A/T maintains the required N1 (thrust) limits selected in the FMC. When it is avtive, N1 is annunciated on the Flight Mode Annuciator Display for A/T Mode.

I have a headache...... anybody else????

I noticed the 'N1' thang on the Lear 45 panel ages ago. Never knew what it was. Now I do.

Alrighty then! Thank you, RD.

Still doesn't explain why or when a guy would want to use it. Even set at 100%, there isn't enough power for takeoff. :?

I seem to remember from school days that it was "N" for number of turns, as in a rotational speed.

So, really what it is...
It's a % of maximum RPM of the primary or outter fan section of the engine.
%RPM was introduced for display reasons in some avionics and FMS's.

N2 is sort of the same but there is pressure and temp calculations that go into that as well because it is in the core of the engine, IE compression fans, I think.
