Registrierung, Akkulaufzeit, Wind (METAR) und Nutzlast vs. MTOW — schnelle Schätzungen vor dem Flug.

Do I need to register my drone?

Enter take-off weight and camera — based on EASA Open category rules.

Yes — register the UAS with your NAA (249 g, camera/audio sensor).

Registration
Required
Certificate
A1/A3
  • Operator and UAS registration with your NAA is required.
  • A1/A3 remote pilot certificate covers most hobby Open category flights.
  • Check geo-zones in your national UTM map before every flight.

Flight time calculator

Enter battery capacity (mAh) and average current (A) for an approximate hover/cruise time.

Result

Estimated flight time: 16 min (80% pack capacity, 15 A average draw).

Indicative only. Wind, payload and temperature change real endurance.

Wind safety calculator (METAR)

Enter wind manually or load METAR from a nearby aerodrome (m/s).

OK to fly

Conditions look OK — 5 m/s ≤ 8.4 m/s safe limit.

  • Drone rating: up to 12 m/s wind.
  • Recommended limit (70%): 8.4 m/s.
  • Above the limit — postpone the flight or reduce altitude and distance.

METAR is aerodrome-level; local conditions may differ.

Payload (MTOW) calculator

Empty aircraft weight plus payload vs. maximum take-off mass (MTOW).

Within limits

Payload 200 g is within limits — total 1100 g ≤ 1200 g MTOW.

Max payload: 300 g

Rechner-FAQ

Ar dronų skaičiuotuvai nemokami?
Taip. Registracijos tikrinimas, skrydžio laikas, vėjas (METAR) ir naudingosios apkrovos (MTOW) skaičiuotuvai Žinių centre yra nemokami.
Kam skirtas naudingosios apkrovos skaičiuotuvas?
Jis tikrina tuščią BO svorį + naudingąją apkrovą (kamerą, krovinį) prieš maksimalų kilimo svorį (MTOW) — svarbu prieš skrydį su papildoma įranga.
Ar skrydžio laiko skaičiuotuvas tikslus?
Tai orientacinis hover/cruise laikas pagal baterijos mAh ir vidutinę srovę. Vėjas, šaltis ir apkrova keičia realų skrydžio laiką.
Iš kur imami vėjo duomenys?
Galite įvesti vėją ranka arba įkelti METAR iš artimiausio aerodromo (pvz. EYVI, EYKA). Vietoje sąlygos gali skirtis.
