Hi, Just curious if anybody knew if the Tu-114 ever sported the NAS-1 system (or similar) for navigation?
regards,
Macs

According to Mjr Pizzo an US aviator who flew onboard the first Tu-114 with President Chrushew from Washington to Moscow, they had navigation gear on board maybe similiar to the Tu 124 NI-50, but navigated from one weathership to the next.
"Our USAF crew included Capt. Harold E. Renegar, AC; MSgt
Gaylor Robinson, radio operator, and myself. The day prior to flight
Captain Renegar introduced me to my new Russian counterpart in the
TU 114. This aircraft is much more advanced than the TU 104; many
of the instruments have been improved and, in addition, there were
new types of equipment. The Russian navigator displayed the same
spirit of friendship and cooperation that had been offered by the crew
of the TU 104. A complete briefing was given, and I also received an
abbreviated safety preflight on use of oxygen equipment. I was told
that there was an oxygen bottle above the navigator compartment that
would be available in case of decompression.
In the TU 114 the navigator has newer radar and Loran sets
than in the ‘ 104, and also an improved true heading unit.
In addition,
the TU 114 has a periscopic sextant that is a permanent part of the
aircraft.
...
Prior to our departure we received the forecast from Weather
Central and I drew up my flight plan. This weather information was
made available to the Soviet crew for their flight planning purposes.
However, they received their own weather through the Soviet Embassy,
and their metrological office used our weather as a basis for
comparison. I did not learn which of the two was the more accurate
forecast.
This flight, I felt sure, would afford me the opportunity to observe
firsthand a top notch Soviet crew doing celestial navigation as
our route would be more over water than the previous flights. But
again, this was not the case. The Soviets had stationed four vessels
approximately 250 miles apart in the ocean and each vessel had homing
facilities on board. You guessed it; radio compass navigation once
more! So once again my ETAs were ATAs, as I had no idea where the
ships were located and therefore I had to rely on DR only.
Our cruising altitude was around 30,000 feet, with a speed of
approximately 405 knots TAS. The Soviets had two crews on board
and approximately halfway through the trip the secondcrew took over
for the last half of the mission to Moscow. All of our position reporting
was made through English speaking stations. At no time did the Soviets
attempt to make any calls other than HF contacts with Moscow.
There were no problems encountered whatsoever, and the entire flight
was extremely smooth.

Regards

Walter
