Es ist schwierig aus der Fragestellung zu erkennen, um was es geht. Falls es um JAR EU-OPS 1.235 Noise abatement procedures geht, dann ist klar, dass das nicht mehr in Kraft ist seit der Air Ops Regulation.

Falls es um ein übliches Leichtflugzeug geht (von Cessna bis Twin Otter und nicht Annex II), dann wäre der Ersatz für dieses Gesetz neu im Part-NCO, EU No 800/2013:
NCO.OP.120 Noise abatement procedures — aeroplanes, helicopters and powered sailplanes
The pilot-in-command shall take into account published noise abatement procedures to minimise the effect of aircraft noise while ensuring that safety has priority over noise abatement.
Entschuldigt, falls ich das Thema verfehlt hätte.
(Ich finde dieses Gesetz noch interessant, da es uns einen längeren Hebel gibt bei Präzisionsplatzrunden usw. In der Schweiz gibt es Plätze da muss man im Short Final einer Kuhweide ausweichen, da der Lärm die Milchproduktion der Kühe beeinflusse. Da könnte man jetzt stur sein und versuchen zu argumentieren, dass das eigene Leben/die Sicherheit doch etwas wichtiger ist als ein paar Milliliter Milch. :-) )
Edit, ich habe nochmals etwas gefunden:
Im Part-NCC ist das Thema genauer geregelt. Part-NCC betrifft jedoch nur non-commercial complex aircraft. Also Privatjets etc. (denn auch Twin-Turboprops unterliegen dem Part-NCO aufgrund einer EU-Derogation). Hier die Vorschriften (Implementing Rule und AMC/GM) für die NCC-Flieger:
NCC.OP.120 Noise abatement procedures
The operator shall develop operating procedures taking into account the need to minimise the effect of aircraft noise while ensuring that safety has priority over noise abatement.
Es gibt im Part-NCC, im Gegensatz zum obenstehenden Part-NCO, auch weitere Guidance dazu:
AMC1 NCC.OP.120 Noise abatement procedures
NADP DESIGN
(a) For each aeroplane type two departure procedures should be defined, in accordance with ICAO Doc. 8168 (Procedures for Air Navigation Services, ‘PANS-OPS’), Volume I:
(1) noise abatement departure procedure one (NADP 1), designed to meet the close-in noise abatement objective; and
(2) noise abatement departure procedure two (NADP 2), designed to meet the distant noise abatement objective.
(b) For each type of NADP (1 and 2), a single climb profile should be specified for use at all aerodromes, which is associated with a single sequence of actions. The NADP 1 and NADP 2 profiles may be identical.
GM1 NCC.OP.120 Noise abatement procedures
TERMINOLOGY
(a) ‘Climb profile’ means in this context the vertical path of the NADP as it results from the pilot’s actions (engine power reduction, acceleration, slats/flaps retraction).
(b) ‘Sequence of actions’ means the order in which these pilot’s actions are done and their timing.
GENERAL
(c) The rule addresses only the vertical profile of the departure procedure. Lateraltrack has to comply with the standard instrument departure (SID).
EXAMPLE
(d) For a given aeroplane type, when establishing the distant NADP, the operator should choose either to reduce power first and then accelerate, or to accelerate first and then wait until slats/flaps are retracted before reducing power. The two methods constitute two different sequences of actions.
(e) For an aeroplane type, each of the two departure climb profiles may be defined by one sequence of actions (one for close-in, one for distant) and two above aerodrome level (AAL) altitudes/heights. These are:
(1) the altitude of the first pilot’s action (generally power reduction with or without acceleration). This altitude should not be less than 800 ft AAL; or
(2) the altitude of the end of the noise abatement procedure. This altitude should usually not be more than 3 000 ft AAL. These two altitudes may be runway specific when the aeroplane flight management system (FMS) has the relevant function that permits the crew to change thrust reduction and/or acceleration altitude/height. If the aeroplane is not FMS equipped or the FMS is not fitted with the relevant function, two fixed heights should be defined and used for each of the two NADPs.
