Along the route the wind was South-Westerly, 80-100 km/h, and the temperature was minus
48°С. The airplane was flying above the clouds, no icing conditions were present.

By the time the airplane entered the Sochi aerodrome zone at 22:00, the weather conditions there
were determined by the postfrontal area of a cold front with waves: cumulonimbus producing
precipitations, mist, and low broken nimbus.
• Starting from 22:00 the weather conditions at Sochi aerodrome were the following:
As observed at 22:00: surface wind 100°, 1 m/s, visibility 4000 m, light rain showers, mist,
considerable clouds (5-7 octant), with the cloud ceiling at 180 m, overcast
cumulonimbus with the cloud ceiling at 820 m, temperature +11°С, dew point +11°С, pressure
1016 hPa; the mountains partially in cloud, friction coefficient 0.5.
• Two-hour forecast for landing:
- at times visibility 1,500 m, mist, vertical visibility 150 m.
• 22:07 check measurement upon the tower controller’s request:
- visibility 4,000 m, light rain showers, mist, considerable clouds (5-7 octant), with the cloud
ceiling at 160 m, overcast cumulonimbus with the cloud ceiling at 820 m.
• 22:09 check measurement at the holding controller’s request:
- visibility 4,000 m, light rain showers, mist, considerable clouds (5-7 octant), with the cloud
ceiling at 190 m, overcast cumulonimbus with the cloud ceiling at 820 m.
In connection with the abrupt descent of the cloud ceiling, at 22:11 an observer informed the
controller via loudspeaker: “…the top…at 100 m, at the second runway 400 m”, having made a
mistake in the phraseology (she said ‘the top’, rather than ‘the ceiling’).
The final controller immediately advised the flight RNV 967 crew of the cloud ceiling: “Flight
RNV 967, abort descent, cloud ceiling at 100 m…”.
At 22:16 the observer got an alarm signal “Search and Rescue Service” from the tower controller
and urgently measured all meteorological parameters.
• Observed weather at Sochi aerodrome measured after the alarm signal at 22:17:
Surface wind 130°, 2 m/s, forecast wind at the holding area level 080°, 4 m/s; visibility 4,000 m,
light rain showers, mist; considerable clouds (5-7 octant), with the cloud ceiling at 160 m,
overcast cumulonimbus with the cloud ceiling at 820 m; air temperature +11°С, dew point
+11°С, atmospheric pressure 1016 hPa; the mountains partially in clouds, the wet runway,
friction coefficient 0.5; the two-hour weather forecast for landing: at times visibility 1,500 m,
mist, vertical visibility 150 m.
While lining up on the final course, the crew of flight RNV 967 was kept informed of the
observed weather conditions at Sochi aerodrome.

The observed weather at Sochi aerodrome was measured by means of the certified Automatic
Meteorological Information and Measurement System of the Russian Federation (AMIS), Type
Certificate No. 89.
The meteorological equipment of Sochi aerodrome passed a metrological check, had the
appropriate certificates, and was serviceable at the time of the A320 EK-32009 accident.
1.4 Aids to Navigation
The aerodrome in Sochi is equipped with navigation, landing and ATC aids to control flights and
assist their navigation and landing in the day and night time in accordance with the established
aerodrome minima.
1.8.1. The aerodrome is equipped with landing system equipment with MHland=24° and a nondirectional
radio beacon (NDB) with MHland= 60° to support airplane descent and approach.
The landing system equipment on RW 02 consists of the inner marker beacon located on the
runway extended centre line at a distance of 1,025 m from its end, and the outer marker beacon
located on the runway extended centre line at a distance of 2,646 m from its end;
The radio marker beacon for RW 06 is located on the runway extended centre line at a distance of
1,454 m from its threshold.
1.8.2. Two radio-beacon instrument landing systems with MHland= 024° and 060°:
• Radio-beacon system SP-80U, installed with MHland=024° and consisting of:
- a localizer located on the runway extended centre line at a distance of 250 m from
the RW 02 end.
- a glide-slope beacon located at a distance of 300 m down RW 02 end and 129 m to
the right from its centre line. The glide slope is 2° 50'.
• a SP-80U radio-beacon system, installed with MHland=060° and consisting of:
- a localizer located on the runway extended centre line at a distance of 835 m from
the opposite end of RW.
- a glide-slope beacon located at a distance of 317 m from the RW 02 end and 130 m
