A sua pergunta está abrangida (para os regulamentos da EASA) no documento Especificações de certificação e material de orientação para concepção de aeródromos ( link ) em duas seções:
- Declive de Taxiway (CS ADR-DSN.D.265)
- Mudanças no declive do trajeto (CS ADR-DSN.D.270)
CS ADR-DSN.D.265 Longitudinal slopes on taxiways
(a) The safety objective of limiting the longitudinal taxiway slope is to enable stabilised safe use of taxiway by an aircraft.
(b) The longitudinal slope of a taxiway should not exceed:
- 1.5% where the code letter is C, D, E, or F; and
- 3% where the code letter is A or B.
CS ADR-DSN.D.270 Longitudinal slope changes on taxiways
(a) The safety objective of limiting the longitudinal taxiway slope changes is to avoid damage of aircraft and to enable safe use of taxiway by an aircraft.
(b) Where slope changes on a taxiway cannot be avoided, the transition from one slope to another slope should be accomplished by a curved surface with a rate of change not exceeding:
- 1% per 30m (minimum radius of curvature of 3000m) where the code letter is C, D, E,or F; and
- 1% per 25m (minimum radius of curvature of 2500m) where the code letter is A or B.
(c) Where slope changes in (b)(1) and (2) are not achieved and slopes on a taxiway cannot be avoided, the transition from one slope to another slope should be accomplished by a curved surface which should allow the safe operation of all aircraft in all weather conditions.
