ADR.OPS.B.090 Use of the aerodrome by aircraft exceeding the certified design characteristics of the aerodrome

CERTIFIED AERODROME DESIGN CHARACTERISTICS In accordance with point ADR.AR.C.035, the certificate is considered to include the aerodrome’s certification basis, the aerodrome manual, and, if relevant, any other operating conditions or limitations prescribed by the Competent Authority and any Deviation Acceptance and Action Documents (DAAD).

WHEEL BASE The clearance distance on a runway turn pad or on a taxiway is determined with regard to the dimensions of the outer main gear wheel span (OMGWS). For aeroplanes with an OMGWS between 6 m up to but not including 9 m, the clearance distance on a runway turn pad or on a curved portion of a taxiway is determined with regard to the OMGWS but with a further differentiation in reference to the wheel base (see CS ADR-DSN.B.095, CS ADR-DSN.D.240, and additionally CS ADR-DSN.D.250 and CS ADR-DSN.D.255). Point ADR.OPS.B.090 is also applicable in this case.

ELEMENTS TO BE ASSESSED — AIRCRAFT CHARACTERISTICS

(a)Wingspan

(1)wake turbulence;

(2)gate selection;

(3)aerodrome maintenance services around the aeroplane;

(4)equipment for disabled aeroplane removal;

(5)de-icing; and

(6)the dimensions of aeroplane maintenance facilities.

(b)Wheel base

(1)terminal areas.

(c)Fuselage length

(1)passenger gates and terminal areas;

(2)the dimensions of aeroplane maintenance facilities.

(d)Fuselage height, in particular door sill height and wing height

(1)the operational limits of the air bridges;

(2)mobile steps;

(3)catering trucks;

(4)persons with reduced mobility;

(5)dimensions of the apron;

(6)door longitudinal position;

(7)potential obstacles close to the door (e.g. probes);

(8)fuelling; and

(9)de-icing.

(e)Tail height

(1)the dimensions of aeroplane maintenance facilities.

(f)Maximum aeroplane mass

(1)wake turbulence.

(g)Engine characteristics

(1)design of air bridges; and

(2)location of refuelling pits on the aircraft stand. The engine characteristics include engine geometry and engine airflow characteristics, which may affect the aerodrome infrastructure as well as ground handling of the aeroplane and operations in adjacent areas which are likely to become affected by jet blast.

(h)Maximum passenger and fuel carrying capacity

(1)terminal facilities;

(2)fuel storage and distribution;

(3)air bridge loading configuration.

(i)Flight performance

(1)wake turbulence;

(2)noise. ADDITIONAL ELEMENTS TO BE ASSESSED — AIRCRAFT GROUND SERVICING REQUIREMENTS The following non-exhaustive list of aircraft ground servicing characteristics and requirements may affect the available aerodrome infrastructure:

(j)ground power;

(k)passengers embarking and disembarking;

(l)cargo loading and unloading;

(m)fuelling;

(n)pushback and towing;

(o)de-icing;

(p)taxiing and marshalling;

(q)aeroplane maintenance;

(r)RFFS;

(s)equipment areas;

(t)stand allocation; and

(u)disabled aircraft removal. Each assessment is specific to a particular type of aircraft and to a particular operational context. The assessment may require a review of the obstacle limitation surfaces at an aerodrome as described in Chapters H and J of CS-ADR-DSN. At aerodromes where low-visibility procedures are implemented, additional procedures may be implemented to safeguard the operation of aircraft. Additional processes that ensure suitable measures are in place to protect the signal produced by the ground-based radio navigation equipment may be necessary at aerodromes with precision instrument approaches. Further guidance on this issue is contained in ICAO Circular 305-AN/177 and ICAO Circular 301-AN/174. In any case, the elements that have to be taken into account for the safety assessment are, without prejudice to other assessments that may have to be conducted, in accordance with other applicable requirements contained in Part-ADR.OPS.
