/* Lp Rait Kalda Lennuamet Meie 05.09.2019 nr 5.1-10/117-1 [email protected] Lõõtsa 5 11415, Tallinn Taotlus Austatud Peadirektor, Seoses hetkel Lennuliiklusteeninduse AS poolt eest veetava projektiga “Navigatsiooni taristu ratsionaliseerimine (NIRP - Navigation Infrastructure Rationalisation Plan for year 2020+)”, soovime Lennusalga poolt esitada omapoolse ettepaneku, mis arvestaks meie opereerimise eripäradega. Projekti põhirõhk on DME/DME navigeerimissüsteemi katvus Eesti piires alates FL095-st (~3km), mida hetkel võib pidada ainukeseks alternatiiviks navigeerimisel/õhusõiduki asukoha määramisel juhul kui GNSS side kaob/on häiritud. Lennuliiklusteeninduse AS ise ei näe vajadust suurendada mainitud projekti raames DME/DME katvust ka allpool lennutasandit FL95. Nende põhirõhk on tsiviillennunduse juhtimisel ning selle seisukohast pole allpool nimetatud kõrgust vajadust navigatsiooni täpsuse suurendamiseks/säilitamiseks GNSS side puudumisel. Presenteeritud katvusalade prognoosid aga madalamatel kõrgustel (allpool FL95) tõid välja probleemsetena lõuna- ja kagu-Eesti katvuse. Sooviksime, et planeeringus oleks DME/DME võimekus Eesti siseselt laiendatud ka allpool lennutasandit FL95. Ideaalis näeksime katvust just Ida- ja Kagu-Eestis kuni 1000 meetrini, kuid iga meeter sellest allapoole laiendab meie võimekust toetada riiklike ülesandeid ohutumalt. Meie ettepanek oleks modelleerida süsteemi prognoositavat katvusala selliselt, et nimetatud piirkond saaks suuremat tähelepanu – läbi plaanis olevate majakate ümberpaigutamise või vajadusel ühe/mitme lisa DME majaka paigutamise kagu-eesti piirkonda. Võttes arvesse riiklikule lennundusele seatud ülesandeid ning tõenäolist õhuruumis navigeerimise tulevikku, leiame, et antud ettepanek aitaks lahendada võimalikke esile kerkivaid probleeme operatiivsel tasandil.

Current VOR and DME stations, operated by EANS and Tallinn Airport Ltd, are approaching the end of their operational life. During 2018 EANS, in cooperation with Estonian CAA and airspace users, initiated assessment of current navigation environment in Tallinn FIR amongst airspace users to analyse their requirements to provide rationalized ground-based navigation aid facilities in Tallinn FIR. In order to develop current Navigation Infrastructure Rationalisation Plan, the following main activities were performed by EANS during the Study:  EANS has developed document “Estonian navigational and operational environment description” ver.1.0.  Questionnaires were prepared and distributed to Airspace Users and local Estonian Airports / ANSPs to collect requirements about airspace users needs in ground-based navigation aid infrastructure. The feedback was analysed by EANS and “Analysis of Navigation Questionnaires” version 1.0 was prepared.  “Aircraft Navigation Capabilities Analysis” version 1.0 has been conducted by EANS. The analysis supplements the quarterly report on GNSS and PBN fleet capability, performed by Eurocontrol.  Customer consultation meeting was organised in EANS premises at 05.10.2018 by EANS Study team. Estonian CAA, Tallinn Airport, Military service provider and airspace users were participated at the meeting. “EANS view on possible operational concept of NAV Infrastructure Rationalization in Tallinn FIR between 2018-2022” “Analysis of Navigation Questionnaires” was presented and discussed. This Navigation Infrastructure Rationalisation Plan is based on the Study results. 3/8  Navigation Infrastructure Rationalisation Plan for year 2020+ 2 Purpose of the document The document describes in details operational aspects of ground-based navigation aids, previously broadly described in “EANS view on possible Operational Concept”.

Lennuliiklusteeninduse AS soovib tulevikus antud projektiga tagada DME/DME kattuvus Tallinna FIR-is alates kõrgusest FL95, kusjuures DME/DME navigeerimissüsteem oleks ainukene alternatiivne võimalus navigeerida, kui GNSS abil navigeerida ei ole võimalik. Lennuliiklusteeninduse AS-i eesmärk ei ole kindlustada navigatsiooni kattuvus allpool FL95. Politsei- ja Piirivalveamet on saatnud Lennuametile ettepaneku navigatsioonitaristu ratsionaliseerimisel arvestada lisaks nende opereerimise eripäradega ja tagada DME/DME kattuvus ka allpool FL95, kus peamiselt toimub Politsei- ja Piirivalveameti lennutegevus. Parem navigeerimisvõimekus madalatel kõrgustel aitaks Politsei- ja Piirivalveametil oma ülesandeid täita ohutumalt. Võttes arvesse Eesti õhuruumipoliitikat, mille kohaselt on Eestile riikliku lennundustegevuse raames oluline tagada turvaline ning stabiilne sise- ning välisjulgeolek, toetab Lennuamet Politsei- ja Piirivalveameti ettepanekut DME/DME taristu planeerimisel arvestada ka madalamate kõrgustega, et vältida tulevikus võimalikke probleeme navigeerimisel. Palume Majandus- ja Kommunikatsiooniministeeriumi seisukohta, kas Lennuliiklusteeninduse AS peab DME/DME kattuvuse tagama ka FL95-st madalamatel kõrgustel.
