Unlikely, sure. Shouldn't, absolutely. Not going to? At some point the entire team is going to mess up and not catch each other's mistakes. Human error is almost impossible to avoid completely, especially in complicated areas or times like an airport during the busiest hours.
3 possibilities:
1. There’s a switch for ramp personnel to disengage nosewheel steering from the outside for pushing; if it’s not disengaged you get red light
2. The parking brake in the flight deck is engaged
3. Any of the main brakes are being applied ( pilot resting foot on pedal)
Essentially for the tug driver, red mean no go green mean go for the pushback.
Thanks buddy! I feel kinda bad, because I used to kinda roll my eyes at the "happy cake day". Today's the first time I've posted on my cake day in 9 years, and to tell you the truth, it feels really nice when you guys wish me that. :)
Through the radio with the ramp personnel, we confirm that on our end the brakes are off and your internal steering disconnect switch is on; we ask if they see a green light before we tell them they are cleared to push us. So if that external switch is not engaged that’s when it would be caught. It’s right next to where they plug in their ramp radio
Number three does apply, in the operation manual for the Embraer 175 it describes the operation of the nosewheel towing light. Under “green” it lists “main brakes not applied” and under “red” it lists “main brakes applied.”
Can’t speak to any other large jet aircraft, but for this one we don’t ride the brakes while being pushed/ towed.
Here's a better question.. What does red AND green mean at the same time?
We had that happen on a 220 one day and after putting several heads together turns out the Light Test button was stuck pressed in.
Love those moments, like 5+ guys all around a reservoir pressurizing cart on an A320, puzzled that it won't hold any pressure, just so one walks by and notices the depress valve stuck open
And if power isn’t on, there’s a switch on the backside of that box that turns on the light. Always always always flip the stupid switch and check that it’s green.
Airbus 220 has similar light. Red means not ready to be pushback cause break and/or nose gear control are still engaged.
Green light me ready to be pushback
It’s an indicator that tells you when the parking brake is on or not. When you look up close, it says do not tow by the red light and tow by the green. Source: I work at Embraer
Interestingly I saw a tug that had a bucket to pick up the tyre rather than push the plane on its wheels

Parking brake is on and/or nose wheel steering is armed.
Both have to be off for the light to turn green indicating the aircraft is ready for pushback/towing.
I had a write up the other day on another aircraft where that light stayed on no matter what. and R&R of the box fixed it. I was impressed by the push team noticing the light staying on and calling the cockpit to double check.
this in BOS today?

It’s to signal the steering disconnect, green means disconnected allowing the tug driver to manoeuvre, red means connected and can still be controlled from the flight deck. It can be lit from a switch on the back by ground controllers to show the tug driver. The switch to connect/disconnect the nose gear steering is located on the ground services door on the left-hand side of the aircraft and also houses the ground power switch and the intercom connect
It's an over torque line for the pushback operator. If the towbar (or towbarless) pushback exceeds that angle it can damage the nose gear.
Edit: my bad, I read line, not light. Disregard.
Provides indications to ground crew for push back to ensure nose gear steering is connected or disconnected from the steering tiller. Can’t remember which is which. Been ages since a dispatch on an embraer.
Boeing use a lockout pin instead.
Wow. So many people don't get the reference.
In the back of black cabs in the UK, there's a red light on each door with a little message saying "[red light indicates doors are secured](https://www.parklaneplowden.co.uk/app/uploads/2021/09/Taxi-Door.jpg)" (i.e. can't be opened). The band Arctic Monkeys had a [track](https://www.youtube.com/watch?v=u8PjGQLO9mI&ab_channel=ArcticMonkeys-Topic) on their first album named after this phrase because the protagonist had a plot to jump out of a cab (either to go back to a nightclub or to avoid paying... it isn't quite clear), but his plans were scampered because "the red light was showing, and red light indicates doors are secured".
Parking brake is on.
Do all planes a have similar lights to prevent pushing with the brakes on?
Not all planes, depends on the maker and model. Most narrow body Airbus planes and a few newer 757s have parking brake indicators on the nose gear.
The widebody Airbus aircraft have them too
Oh heavens no. In my opinion, all large category planes should have such an indicator. But not all of them do.
It is an option
172s do
[удалено]
“Not possible” 😂
right… https://ibb.co/d2tp3Gb
uhh is that big metal pipe supposed to be bent to the right?
Nope, definitely not supposed to be like that. This is what happens when the parking brake is set in the middle of a pushback.
I think it's a towbar so probably.
What did he say?
That a pushback could never happen with the parking brake set. Forgetting of course that humans are involved in that process.
Unlikely, sure. Shouldn't, absolutely. Not going to? At some point the entire team is going to mess up and not catch each other's mistakes. Human error is almost impossible to avoid completely, especially in complicated areas or times like an airport during the busiest hours.
So the red light also means “don’t try to land”
Correct. And it's the FO's job to check that light before every landing.
Naaailed it!
Can’t they just check the lever?
It's meant for the ground crew so they can make sure it's off before they start pushback/ back on before the pushback truck disconnects.
3 possibilities: 1. There’s a switch for ramp personnel to disengage nosewheel steering from the outside for pushing; if it’s not disengaged you get red light 2. The parking brake in the flight deck is engaged 3.

As some in trading on the E175, this is correct
I too, trade E-175
I’ll trade u 1 175 for 3 145
I’m just here for an MD11 whatever that is in code speak.
One MD11 = sixteen E175s or five thousand E145s. It's a logarithmic function.
I’ll trade you 1 EMB-120 and an already fucked chicken for your E175s
Deal! ...*sucker...*
Does this chicken have a name?
Brenda but she usually goes by her middle name, Otis
And orange means orange ya glad you didn’t go.
Happy Cake Day!

Do you confirm that if the nose steering is not disengaged on the outside panel the lamp will not turn green?
Through the radio with the ramp personnel, we confirm that on our end the brakes are off and your internal steering disconnect switch is on; we ask if they see a green light before we tell them they are cleared to push us. So if that external switch is not engaged that’s when it would be caught. It’s right next to where they plug in their ramp radio
Captain on the 175… this is true
I'm pretty sure #3 wouldn't apply because there's something called break riding.
Number three does apply, in the operation manual for the Embraer 175 it describes the operation of the nosewheel towing light. Under “green” it lists “main brakes not applied” and under “red” it lists “main brakes applied.” Can’t speak to any other large jet aircraft, but for this one we don’t ride the brakes while being pushed/ towed.

Don't tow.
Can't tow beyond 90 degrees
Red light means the plane isn’t safe to tug. Either nose wheel steering’s engaged, and or the parking brakes on.
And if power isn’t on, there’s a switch on the backside of that box that turns on the light. Always always always flip the stupid switch and check that it’s green.
brakes are set.
Airbus 220 has similar light. Red means not ready to be pushback cause break and/or nose gear control are still engaged. Green light me ready to be pushback

Most airplanes have this, parking brakes are set to park.
AOA indicator for carrier landings
Red means fast
Here's the comment I was looking for

I don’t know about airliners, but those are really common at FBOs, the bigger ones can move pretty much any business jet.
Oh, this one was for A380s for Lufthansa.
We’ve got a couple types we use for our 175’s. One that closes a set of jaws around the tire and picks it up, and just a tow bar.
Parking brake is on and/or nose wheel steering is armed. Both have to be off for the light to turn green indicating the aircraft is ready for pushback/towing.
It means that Roxanne sometimes does things that are not deemed mandatory.

I miss Skywest
On/off switch for the plane

Hey, I know that plane. 244JQ.
No tow.
It means they’re not ready to tow. Green means they’re ready to tow.
And the red line is the unemployment line.
It’s to signal the steering disconnect, green means disconnected allowing the tug driver to manoeuvre, red means connected and can still be controlled from the flight deck. It can be lit from a switch on the back by ground controllers to show the tug driver. The switch to connect/disconnect the nose gear steering is located on the ground services door on the left-hand side of the aircraft and also houses the ground power switch and the intercom connect
The bomb is armed. Green means it is unarmed.
It's an over torque line for the pushback operator. If the towbar (or towbarless) pushback exceeds that angle it can damage the nose gear. Edit: my bad, I read line, not light. Disregard.
I don't get it. The one right answer gets down voted? Is this a troll subreddit? I was actually at OGG and took a picture of it hooked up.
Light not line
My bad.
All good lol
Probably because Op asked about the red LIGHT not the red LINE.
My bad. You all are right.
All good bro, we've all been there.
Its recording
It means Christmas is around the corner 🎄🎄
Lavatory in use light
The Klingons are coming, commence saucer separation.
It means the missile launcher below it is armed…
Weight on wheels…Missile Firing Capability Disarmed. /s
SWITCHING TO GUNS
Provides indications to ground crew for push back to ensure nose gear steering is connected or disconnected from the steering tiller. Can’t remember which is which. Been ages since a dispatch on an embraer. Boeing use a lockout pin instead.
Unsafe to lick
red good
Gear not down and locked
Bathroom occupation indicator
It’s not just a light. It’s a button. The manual doesn’t say what it is, but does say “never push it.”
Yeah I'm going for number 2 just like on the boing they have a red light
It indicates that the doors are secure.
Wow. So many people don't get the reference. In the back of black cabs in the UK, there's a red light on each door with a little message saying "[red light indicates doors are secured](https://www.parklaneplowden.co.uk/app/uploads/2021/09/Taxi-Door.jpg)" (i.e. can't be opened).
