airfield is fairly golid and suitable for landing of planes up to 15 thousand
kilograms in weight. There are two approaches to the runways.- The longer one
is 600 meters long, and 40 meters wide, and is made of asphalt. The shorter
one is 150 meters long and 30 meters wide. The airport is equipped with a con-
trol tower which is approximately 12 - 15 meters higher than the three-story
airport station building. The'station is a steel and brick structure, with
glass walls on the upper floor. The equipment for night flights is as follows:
a T-light, locateda'at the beginning of the starting runways there were beacons
on hangars C and B. The beacon located on hangar B bad a one-color light;
the lighthouse on hangar 0 id a two-color turning searchlight (white and green).
The light is visible for 20 kilometers. On the control tower there is a small
searchlight lighting the approach to the runways. The main runway 220 - 240?
is maIrked as followsa at the beginning of the runway, three green lights; the
rur*ay is marked with white lights on both sides. The three last lights are

and also all lights in the area of the airport, the g oniometric station and trans.
mitter in Jenec. All devices are double in case of emergency. There is also blind
landing equipment, type SBA lorenz,in the control tower. In addition, there is
a siren for the "stop the motors alarm" which is used when all other devices fail.
This siren stops all the motors in the airport in order to enable the personnel
to ascertain the position of the airplane by listening. The regional flight con-

EP Z. frequency 322 klh/sec. This goniometric station servat for UUGH- landing (dir--
rection distance). If the OH-DD system is used for landing, the station is
connected with the goniometric station in Stredokluky which is equipped with on's
apparatus EP 2, frequency 322 klh/sso. The goniometric device system A AJCuC,

in Stredokluky is in permanent service. About 14 kilometers northwest of the
beginning of the start runway, near the village of Hostice, there is a beacon
which. beams the letters PA. The radio-range transmitter beams the letters AN
north to south and west to east. This radio-range is located in the trans-
mitter in Jenec. Another transmitter beams letters OKL in all directions.
This transmitter is also in Jenec. The frequency and time is described in ,the
international circulars MOTAML For blind landing the SBA-Lorenz equipment
located on the runway is used. This is the major beacon. About 50 meters
from the beginning of the runway there is a signal transmitter, "Innermarker."
Three hundred meters from the beginning of the same runway there is another
transmitter, "Outermarker." The approaching device SC 51 with the major
beacon on the end of runway 22 with the signal (glide bath) is located be-
tween runways 22 and 26 and between the Innermarker. The details are shown
in the international circulars M TAML In addition, there is a search light
