The earth stations on-board aircraft shall meet the PFD values on Earth given below:
–123.5 dB(W/(m2 • MHz)) for θ ≤ 5°
–128.5 + θ dB(W/(m2 • MHz)) for 5 < θ ≤ 40°
– 88.5 dB(W/(m2 • MHz)) for 40 < θ ≤ 90°
where θ is the angle of arrival above the horizontal plane at the fixed service station location.		Restrictions according Annex 1 and 2 of ECC/DEC/(19)04.

9Authorisation regimeSwitzerland: Notification required.
Liechtenstein: Individual assignment required.
Aircraft radio equipment is listed in the 'Aircraft station license'.
Switzerland: Terminals must be under the control of a network for which a valid spectrum license for the Swiss territory is required.
Liechtenstein: The exemption from the individual assignment requirement only applies under the condition and in the framework of a valid license for the Liechtenstein territory that includes the use of individual customer terminals.
