Nose Gear Door Writing......why?

Thu Feb 24, 2005 1:56 am

i notice that most (i think) airliners have something written on their nose gear doors. its either part of the aircraft registration, or ETOPS, or whatever.

why is this? ....and why there?


thx

So that you can see it when you're under the front of the aircraft.

Cos it's easy for the ramp rats to see. ETOPS especially is important, so is knowing which aircraft you're working on.

ok...i can see that it would be useful to the rampers to make sure the correct luggage, etc., gets on the right aircraft. but how is ETOPS useful to the rampers?

...its obvious i'm not a ramper.....

It is usually the ship number that the airline assigns to each airplane. The registration number (Nxxxxx) on the tail is too difficult to read when the airplane is nosed into the gate. The ship number is what the airlines use on their paperwork, such weight and balance, etc. The flight number changes many times a day for a given aircraft, but the ship number is permanent for a given airline.

But what significance does "ETOPS" have to a ramper?
How does an aircraft being ETOPS effect his/her job duties?

A/C reg. number is to help ground, pilots and mechanics ID the plane without having to walk to the tail of the A/C. ETOPS is important to mechanics. I have also see tire pressure printed on the doors.

I believe ETOPS on the nose gear door is important for mechanics because in order for a twin to receive and retain ETOPS certification, it has to be serviced differently than a non-ETOPS aircraft. One of those certification requirements is, I believe, that the same mechanic cannot work on both engines. This is to ensure that if proper servicing procedures are not followed on one side of the aircraft then the same mechanic won't repeat the same mistake on the other side of the aircraft, with the resulting potential disaster of losing both engines in flight.

Red flyer is right, special maintenance procedures mjust be followed for ETOPS aircraft.

Nose numbers on UA aircraft also identify the aircraft type, the internal layout, and the aircraft number in that series. Of course the ETOPS is improtant to mechanics, they see that and can automatically go into "ETOPS Mode".  Smile

Well i dont know why ETOPS are printed on the nose, but as a ramper for WestJet I can tell you why the tail number printed on the nose gear door helps.

Picture this...
Your on gate 50 waiting for one of our -200s, you see a 3 -200s comming in to the terminal right behind each other, you look on the report and gate 49 and gate 51 have -200s coming in as well. As they approach you look and spot out which one your waiting for so when the aircraft gets near the lead-in line you give the pilot the "This Gate" signal, so he knows to turn in.

One other piece of important info you'll find on most nose gears is a near vertical line, this tells the pushback how far he can turn the nose wheel when pushing the aircraft of the gate.

Hope this helps

Most often the aircraft are given their gate assignment from Ops and they'll know where to go; the marshaller's signal is just a "line up facing me" so the pilot has a point of reference, if there's not a "tree" light bar for him to use (quite a few of the gates on the International Pier in YYC have these... or at least they used to. D32, D33 and D34 had them back in the days of CP)...

he only time the pilots mess it up and go into the wrong gate is when they neglect to read the gate numbers or get overzealous.....  Big grin

You are right about that. However there are distractions which happen and sometimes planes start heading toward the wrong gate. It does happen. With ship numbers painted on the nose it adds a level of redundancy so the ramp knows which plane to expect and make sure they are parked at the right gate. One plane parked at the wrong gate can cause an operational headache which can have a ripple effect throughout the operation.

With Mesaba, the gear doors have the fleet number, and on the Saabs - the model type - A, B, or B+. The model type is important to know when calculation weight & balance, seating capacity, mechanics/mx's, etc.

Registration mark minus the Nationality mark is usually written on the NLG Doors.

Yes I am aware that pilots recieve their gate assignemt from ops.. However we are the kings of last minute gate changes (Aircraft is allready taxing in to the ramp)... so the pilots usually taxi to the gate but not to turn for the gate unless TAC is giving you the clear.

And those light tree systems, are in still in place, however the ground crew including ACA, GGNA, ATS never use them. I have seen them used maybe five times(?) in the year I worked at ATS.

I know, I've watched ATS and their predecessor CanCom get themselves into trouble many times, especially with widebodies, that could've been avoided had the lead in charge on the ground known how to use the light tree system. A few guys I knew who worked for ATS had no idea how to use those system, especially on gates like B24 and C25.

Back in the good old days we used them all the time.... especially with widebodies like A330s and 767s.....

go to www.mfpltd.com

the other day at ads i walked up to find a 732 and a dc-9 i took a close up of the dc-9 nose wheel door and you can clearly reed what is written

the pic is at the bottom of the page

From a passenger's perspective, I love the nose gear numbers, because you can't see the reg # from the terminal, but you can see the front gear clearly. Makes it a lot easier to ID the aircraft you are flying on. I know this is not why they have the numbers there, but it helps me.  Smile
