ED Decision 2013/011/R
Definition of terms and principles used:
(a) A tethered gas balloon consists of a balloon system (envelope, suspension system and gondola) and a tether system that continuously anchors it during operation.
(b) The tether system (winch, pulley, cable and swivel point) includes all components affected by forces resulting from tethering up to and including interface parts with the foundation or counterweight.
(c) The mooring system includes all components affected by forces resulting from the applicable types of mooring (e.g. high and/or low mooring).
(d) The suspension system includes all components suspending the gondola to the envelope (if applicable including the net).
(e) A gondola is a basket or other device (e.g. container, trapeze, harness, seat or platform) suspended beneath the envelope to accommodates the balloon occupants.
(f) The envelope contains the lifting gas.
(g) The swivel point is the connection between the tether system and balloon system allowing rotation of the balloon independent from the tether cable.
(h) Ascent/descent system is the part of the tether system raising and lowering the balloon.
(i) The maximum lift is the sum of the maximum static lift from the lifting gas volume and the maximum dynamic lift, at sea level in International Standard Atmosphere conditions.
(j) The maximum dynamic lift is the highest lift force at the chosen maximum operating wind condition at sea level in International Standard Atmosphere conditions.
EASA balloon regulations define key components. A tethered gas balloon system includes the envelope, suspension, gondola, and tether. The tether system anchors the balloon, while the mooring system secures it when not flying. The gondola carries occupants, and maximum lift considers static and dynamic forces in standard atmospheric conditions.
