Pick your drone by C-class, weight, or model - it tells you where you can fly, what certification you need, and whether registration is required.</p> <p><em>It does not replace official sources. Always verify with your national aviation authority and check airspace restrictions before every flight.</em></p> <br> <br> <style> .dc { width: 100%; } .dc-desc { color: #a0a0a0; margin-bottom: 1.8rem; } .dc-tabs { display: flex; border-bottom: 1px solid #444; margin-bottom: 1.6rem; width: 100%; } .dc-tab { background: none; border: none; border-bottom: 2px solid transparent; flex: 1; text-align: center; padding: 0.55rem 0; font-family: inherit; font-size: inherit; cursor: pointer; color: #888; margin-bottom: -1px; transition: color 0.15s, border-color 0.15s; } .dc-tab + .dc-tab { border-left: 1px solid #444; } .dc-tab.active { color: #73b06f; border-bottom-color: #73b06f; } .dc-tab:hover { color: #d4d4d4; } .dc-panel { display: none; } .dc-panel.active { display: block; } .dc-field { margin-bottom: 1.3rem; } .dc-label { display: block; font-size: 0.8em; color: #888; letter-spacing: 0.1em; text-transform: uppercase; margin-bottom: 0.4rem; } .dc select, .dc input[type="number"] { width: 100%; background: #2a2a2a; border: 1px solid #444; color: #d4d4d4; font-family: inherit; font-size: inherit; padding: 0.5rem 0.75rem; outline: none; appearance: none; -webkit-appearance: none; border-radius: 0; transition: border-color 0.15s; } .dc select:focus, .dc input[type="number"]:focus { border-color: #73b06f; } .dc select option { background: #2a2a2a; color: #d4d4d4; } .dc-hint { font-size: 0.8em; color: #666; margin-top: 0.35rem; } .dc-result { display: none; margin-top: 2rem; } .dc-result.visible { display: block; } .dc-result-header { font-size: 0.8em; letter-spacing: 0.12em; color: #666; text-transform: uppercase; margin-bottom: 0.6rem; } .dc-class-line { font-weight: bold; color: #73b06f; margin-bottom: 1.4rem; line-height: 1.5; } .dc-block { border-left: 2px solid #444; padding: 0.55rem 0.9rem; margin-bottom: 0.8rem; color: #c8c8c8; } .dc-block-label { font-size: 0.8em; letter-spacing: 0.1em; text-transform: uppercase; color: #666; margin-bottom: 0.3rem; } .dc-zones { display: flex; gap: 0.6rem; flex-wrap: wrap; margin: 0.4rem 0 0; } .dc-zone-card { background: #1a1a1a; border: 1px solid #444; padding: 0.5rem 0.75rem; flex: 1; } .dc-zone-card.A1 { border-color: #4dbb4d; } .dc-zone-card.A2 { border-color: #4daaaa; } .dc-zone-card.A3 { border-color: #cc7733; } .dc-zone-name { font-weight: bold; margin-bottom: 0.2rem; } .dc-zone-card.A1 .dc-zone-name { color: #4dbb4d; } .dc-zone-card.A2 .dc-zone-name { color: #4daaaa; } .dc-zone-card.A3 .dc-zone-name { color: #cc7733; } .dc-zone-desc { font-size: 0.8em; color: #888; } .dc-rules { list-style: none; padding: 0; margin: 0.35rem 0 0; } .dc-rules li { display: flex; align-items: baseline; gap: 0.6rem; background: #1a1a1a; padding: 0.4rem 0.6rem; margin-bottom: 0.35rem; color: #c8c8c8; } .dc-badge { font-size: 0.7em; font-weight: bold; padding: 0.1em 0.4em; flex-shrink: 0; letter-spacing: 0.05em; } .dc-badge.ok { background: #1e3a1e; color: #4dbb4d; border: 1px solid #4dbb4d; } .dc-badge.no { background: #3a1e1e; color: #b06f6f; border: 1px solid #b06f6f; } .dc-rule-text { flex: 1; } .dc-rules li small { display: block; font-size: 0.85em; color: #666; margin-top: 0.2rem; } .dc-warning { color: #c8a86f; border: 1px solid #6b5a3a; padding: 0.55rem 0.85rem; margin-bottom: 1rem; line-height: 1.6; } .dc-warning::before { content: '⚠ '; } .dc-divider { border: none; border-top: 1px solid #333; margin: 2rem 0; } .dc-global { color: #666; } .dc-global-label { font-size: 0.8em; letter-spacing: 0.1em; text-transform: uppercase; color: #555; margin-bottom: 0.5rem; } .dc-global ul { list-style: none; padding: 0; margin: 0; } .dc-global ul li::before { content: '— '; } </style> <div class="dc"> <!--p class="dc-desc">Select your drone's C-class, enter its weight, or look up a specific model — we'll show the applicable EU rules, flight zones, and certification requirements.</p--> <div class="dc-tabs"> <button class="dc-tab active" onclick="dcTab(this,'class')">C-class</button> <button class="dc-tab" onclick="dcTab(this,'mass')">Weight</button> <button class="dc-tab" onclick="dcTab(this,'model')">Model</button> </div> <div class="dc-panel active" id="dc-panel-class"> <div class="dc-field"> <label class="dc-label">C-class</label> <select id="dc-sel-class" onchange="dcCalc()"> <option value="">— select —</option> <option value="C0">C0 — max. 250 g</option> <option value="C1">C1 — max. 900 g</option> <option value="C2">C2 — max. 4 kg</option> <option value="C3">C3 — max. 25 kg</option> <option value="C4">C4 — max. 25 kg (legacy / model aircraft)</option> </select> <p class="dc-hint">// only applies to drones manufactured and labelled after Jan 1, 2024</p>
