Question I have:

Older TU134s had a glassed nose, where navigators seat was/is, as shown here:

This is probably a result of upgrading, new electronics, etc, where the need for a glassed nose was no more. Now a question:

Did the layout of a cockpit change? Navigator/his seat is no longer there? Anyone know history of that?

Can't help with any new info, but I always thought it was funny that the Russians held on to this concept for so long. It just looks so antiquated.

According to some internet sources, the solid nose variants have the navigator seated between/behind the pilots.

I wished they had kept it and sold it at a premium rate to airplane fans who would want to sit there just to pretent they were flying the airplane.

The Tu-134 and -134A were produced in both configurations, ie with the glass nose and without it, the latter being an export variant (for countries like the DDR, Czechoslovakia, Poland, etc). The non-transparent nose cone houses the weather radar, which in glass-nosed versions was housed in the 'hump' under the cockpit floor.

The navigator's position was indeed in the glass nose, and was essential for operations in the USSR, as navigational aids were sparsely located and a lot of the navigation relied upon visual reference. In Central Europe, the situation was much better navaids-wise and thus airlines like CSA, LOT and Interflug chose the radar-nosed Tu-134, which lacked the navigator's position and thus provided better operating economics.

Note that the Tu-134B was produced only in the radar-nosed configuration. Many of them were exported to Vietnam, Syria and other countries, while some were operated in the USSR (the Latvian Civil Aviation Directorate being one of the operators, if not the only one).

Very informative OV735. Thank you very much.

As I understand, none were retrofitted with "non-transparent" nose?
And one more: based on some responses here, i am still confused: for the variants without the glassed nose, did they do away with navigator crew member alltogether? or did they just move his seat behind the pilots.

What other aircraft had the glass nose, and what a mess that cockpits in.

This was offered by the manufacturer, but I don't think it has been done.

I'm not 100% sure, but I don't they did that. Many of the radar-nosed export aircraft were sold back to Russia in 1990's, though.

As far as I know, those non-transparent-nosed -134's operated outside the USSR flew with a three-man cockpit of two pilots and a flight engineer, ie no navigator.

Most Soviet aircraft designs of 1960's had those glass noses (An-8, -10, -12, Il-76, Tu-104, -114, -124 & -134 + most of their military aircraft). This kind of cockpit layout indeed has some interesting features - on the Tu-134 glass nosed variants, for example, both the captain and the F/O had their own set of thrust levers on the window side (the interesting thing being that only the Captain's had thrust reverser levers).

I always wondered about the glass noses on their planes. Navigation in Russia makes sense. Was there a military reason, too, even for civil planes?

There sure was.
They could be fitted with machine guns for self defense (what little good that would do).
More important they quite often when flying over western Europe tend to "get lost" and overfly military installations. A glass nose makes a great platform for "observation" cameras (which were on several occasions discovered and confiscated after landing).

Actually, LOT operated both versions, majority of which were 134A with the navigator in front, I flew myself WAW-BRU in 1990 with glassed nose..
