Title: Airline pilots - could you FEEL the difference?
Post by: beet1e on May 28, 2004, 07:20:49 AM
In a previous life, I used to know a UAL baggage handler who worked at ORD. He had reached the point where he could tell which type of plane was approaching just by the sound. But it went beyond that. He could sometimes even tell which airline it belonged to. Back then, UAL was sharing facilities with BA in some cases (eg. at Denver, where BA was able to fly nonstop from London and use UAL gates etc.). I don't know whether that was the case at ORD, but this guy could tell when the approaching plane was a BA plane. How? Most carriers used P&W engines (?) but the British carriers used Rolls Royce engines, which sounded smoother, sweeter.

So my question is - as a pilot in the cockpit, would you be able to tell the difference between P&W and the arguably more refined Rolls Royce units?

Ypur friend is quite full of excrement.

It is not hard to tell some airplanes by sound, but not the airline.  What a load.

RR more refined?  LOL.

BTW, pilots don't have to wonder, they tend to know what engines are on their aircraft, they have to look at the performance charts to plan takeoff power settings etc.

Still laughing at "more refined".  Damn that is a good one.  Does the engine hold out it's pinky while drinking jet fuel?  

I have experience with GE, Pratts, SNECMA and RR engines.  Don't be bragging up them RR if you don't know what your talking about.

I find it hard to beleive different airlines....unless you are going by schedule......but different planes...sure that's not hard after a while.

Your friend certainly could have Beetle, easily, down to the carrier, and plane type. Aren’t you asking about flight performance though?

Yes - that, and any other differences.

Down to the carrier?  Bullchit.

A 757 with Pratt 2037 engines sounds the same regardless of livery.

Same for all the rest.  Paint doesn't make it sound differant.

I can tell many types apart by sound, but haven't hear a paint job taxi by.

Still listening for engine sound.

As I said, the British carriers (BA, Virgin) use RR engines. But UAL does not - uses P&W instead? As there were no Virgin Atlantic planes using the UAL facilities at that time, my friend knew that if he heard RR engines, they'd be attached to a BA plane. Nothing to do with paint, just a simple process of deduction.

Toodle-Pip!

I can believe if you know that only one carrier is running a certain combo airframe/engine at a field, you could identify it, but your original post didn't give that impression.

So, yes, a person who is on the line long enough could tell differant planes by hearing, and if you know only one carrier runs a certain type at that field, it would be possible to identify it.  But not without that specific knowledge.

I remember the sound of RB211 main bearings going out back in the late 80's when I flew the L-1011.

Does that count?

It never happened often enough on a Pratt or a GE to memorize the sound though.

was it a "refined" sound Toad?

Dago - oh, OK then. What I actually said was

Back then, UAL was sharing facilities with BA in some cases
The only British long haul carriers to the USA that I know about are BA and Virgin, and Virgin does not operate a service to ORD. And I gained the impression that UAL did not share its facilities/gates etc. with any other carrier except BA. Therefore, and planes that pulled up where my friend worked were either UAL or BA. Sorry that wasn't clear in the initial post. Hehe, I'll admit it was a bit of a troll. :D;)

Mr. T! Six of us got together in London last night to meet your man Curval. I sat next to Curval. He was telling me that... erm... I get mentioned on the 13thTAS website - made my freaking night! I've been grinning from ear to ear ever since - whatever it was that was said about me. :lol

There is a slight possibility to hear difference between the practices of different airlines though.
Some uses engines more aggressively, some less.. minor differences there and here.
