Note.— This table does not include recommended horizontal beam spreads. 6.2.1.3 requires 360° coverage around an obstacle.
Therefore, the number of lights needed to meet this requirement will depend on the horizontal beam spreads of each light as well as the
shape of the obstacle. Thus, with narrower beam spreads, more lights will be required.
a) 360° horizontal. For flashing lights, the intensity is read into effective intensity, as determined in accordance with the Aerodrome
Design Manual (Doc 9157), Part 4.
b) Between 2 and 10° vertical. Elevation vertical angles are referenced to the horizontal when the light is levelled.
c) Between 2 and 20° vertical. Elevation vertical angles are referenced to the horizontal when the light is levelled.
d) Peak intensity should be located at approximately 2.5° vertical.
e) Peak intensity should be located at approximately 17° vertical.
f) Beam spread is defined as the angle between the horizontal plane and the directions for which the intensity exceeds that mentioned in
the “intensity” column.

Therefore, the number of lights needed to meet this requirement will depend on the horizontal beam spreads of each light as well as the

a) 360° horizontal. All intensities are expressed in Candela. For flashing lights, the intensity is read into effective intensity, as determined
in accordance with the Aerodrome Design Manual (Doc 9157), Part 4.
b) Elevation vertical angles are referenced to the horizontal when the light unit is levelled.
c) Beam spread is defined as the angle between the horizontal plane and the directions for which the intensity exceeds that mentioned in
the “intensity” column.
Note.— An extended beam spread may be necessary under specific configuration and justified by an aeronautical study.

Juhkentali kvartali eskiisi heakskiitmise tingimused
Austatud pr Kork
Aadressidega Liivalaia tn 34/Juhkentali tn 1, Liivalaia tn 36 ja Veski tn 1 hõlmatud maa-ala asub
Lennart Meri Tallinna lennuvälja lähiümbruse sisemises horisontaalpiirangupinnas, mille
absoluutkõrgus on 84,25 meetrit. Kavandatav hoone A absoluutkõrgusega 124 meetrit läbib
nimetatud piirangupinda ligi 40 meetri ulatuses. 18.12.2006 kooskõlastas Lennuamet
teemaplaneeringu „Kõrghoonete paiknemine Tallinnas“ (nr 3-5-7/06/3547), millega määrati
Maakri piirkonna suurimaks lubatud ehituskõrguseks 130 meetrit arvestatuna merepinnast.
Kavandatavad kõrghooned asuvad Maakri piirkonna vahetus naabruses, samuti kinnitab
Lennuliiklusteeninduse AS-i poolt 2016. aastal koostatud aeronavigatsiooniline ekspertiis, et
lennuvälja instrumentaallähenemisprotseduure planeeritav kõrghoone ei mõjutaks.
Lennuametil on enne heakskiitmist Juhkentali kvartali eskiisile järgmised tingimused:
Kavandatava kõrghoone katuse nurkadesse tuleb paigaldada lennuohutustuled. Tulede
parameetrid peavad vastama Rahvusvahelise Tsiviillennunduse Konventsiooni lisa 14 (ICAO
Annex 14) 1. köite tabelis 6-1 ja 6-2 madalintensiivsusega tüüp B tulede nõuetele (vt lisa).
Ehitustegevuse alustamisel tuleb kooskõlastada Lennuametiga lennuvälja piirangupinda
läbiva ehitustehnika kõrgus ja valgustustingimused.
Hoone täiskõrguse saavutamisest tuleb teavitada Lennuametit ning teostada hoone asukoha
koordinaatide ja kõrguse mõõdistamine, mille tulemused edastada Lennuametile.
Nimetatud tingimused palume kanda ehitusprojekti.
Juhime tähelepanu asjaolule, et tegemist ei ole ehitusprojekti õiguslikult siduva kooskõlastusega.
