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.

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.

Rannamõisa külas Keila metskond 10 maaüksuse osa detailplaneering
Austatud hr Sandla
Keila metskond 10 maaüksuse (katastritunnus 19801:002:0199) asub väljaspool lennuväljade
lähiümbruse piirangupindu. Seega ei mõjuta kavandatava 60 meetri kõrguse mobiilsidemasti
rajamine oluliselt õhusõidukite tõusu- ja lähenemisprotseduure. Lennundusseaduse § 35 lg 2
kohaselt kooskõlastab Lennuamet detailplaneeringu järgmistel tingimustel:
• Mast peab olema värvitud sektsioonide kaupa punaseks (või oranžiks) ja valgeks. Masti
tipmine osa peab olema punane (või oranž).
• Mast peab olema valgustatud kahel tasapinnal paiknevate igast lähenemissuunast nähtavate
lennuohutustuledega.
• Lennuohutustule parameetrid peavad vastama Rahvusvahelise Tsiviillennunduse
Konventsiooni lisa 14 (ICAO Annex 14) tabelis 6-1 kirjeldatud madalintensiivsusega tüüp B
tulede nõuetele (vt manuses low-intensity type B).
• Kui masti paigaldamisel kasutatava tõstetehnika kõrgus ületab 100 meetrit arvestatuna
maapinnast, tuleb tehnika valgustus- ja märgistustingimused Lennuametiga eelnevalt
kooskõlastada.
• Masti täiskõrguse saavutamise järel teostada masti asukoha ja kõrguse mõõdistamine.
Mõõdistustulemused edastada Lennuametile 30 päeva jooksul pärast masti täiskõrguse
saavutamist.
Lennuameti antud tingimused peavad olema sisse viidud ehitusprojekti. Muuhulgas nende
puudumisel ehitusprojektist ei saa Lennuamet edaspidi ehitusloa eelnõud kooskõlastada.
