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.

Lennuameti seisukoht Tartu linnas Turu tn 18 krundi ja lähiala detailplaneeringu
algatamise eelnõu osas
Austatud hr Laidre
Lennuametil on Turu 18 krundi ja lähiala detailplaneeringu algatamise eelnõu osas järgmine
kommentaar:
Turu 18 kinnistul paikneb korsten, mille kõrgus maapinnast on 94,3 meetrit ja mida esitatud
eelnõu kohaselt ei kavatseta lammutada. Arvestades, et tegu on piirkonnas domineeriva
lennutakistusega, peab korsten olema Rahvusvahelise Tsiviillennunduse Konventsiooni lisa
14 (ICAO Annex 14) nõuete kohaselt märgistatud ja valgustatud. Konkreetsel juhul on
märgistuse ja valgustuse nõuded on järgmised:
o Korsten värvida vaheldumisi punaseks ja valgeks, nii et korstna alumine ja tipmine osa
oleksid punased.
o Korstna tippu (samas vältides tulede võimalikku suitsuga saastumist) ja keskossa
paigaldada kummalegi tasapinnale võrdse vahega neli lennuohutustuld.
o Lennuohutustulede parameetrite osas on kaks valikut – kas paigaldada ülemisele
tasandile keskintensiivsusega (medium-intensity) tüüp B tuled (parameetrid vastavalt
manuse tabelile 6-1, punane vilkuv, min. valgustugevus 2000 cd) ja alumisele tasandile
madalintensiivsusega (low-intensity) tüüp B tuli (punane pidevalt põlev, valgustugevus
32 cd); või paigaldada mõlemale tasandile keskintensiivsusega (medium-intensity) tüüp C
tuled (punane pidevalt põlev, valgustugevus 2000 cd).
