UAM.POL.VCA.110 General performance requirements

(a)The mass of the VCA:

(1)at the start of the take-off; or

(2)in the event of in-flight replanning, at the point from which the revised operational flight plan applies; shall not be greater than the mass at which the requirements of this Subpart can be complied with for the flight to be conducted, considering expected reductions in mass as the flight proceeds and such fuel jettisoning as applicable.

(b)The approved performance data contained in the AFM shall be used to determine compliance with the requirements of this Subpart, supplemented as necessary with other data as prescribed in the relevant requirement. The IAM operator shall specify such other data in the operations manual (OM). When applying the factors prescribed in this Subpart, any operational factors already incorporated in the performance data contained in the AFM shall be considered to avoid double application of factors.

(c)When showing compliance with the requirements of this Subpart, the following parameters shall be taken into account:

(1)the mass of the VCA;

(2)the configuration of the VCA;

(3)the environmental conditions, in particular:

(i)density altitude;

(ii)wind:

(A)except as provided in point (C), for take-off, take-off flight path and landing, the correction for wind shall not be more than 50 % of any reported steady headwind component of 5 kt or greater;

(B)when take-off and landing with a tailwind component is permitted in the AFM, and in all cases for the take-off flight path, the correction for tailwind shall not be less than 150 % of any reported wind component;

(C)when precise wind-measuring equipment enables the accurate measurement of wind velocity over the point of take-off and landing, wind components in excess of 50 % may be taken into account by the IAM operator, provided that the IAM operator demonstrates to the competent authority that the proximity to the FATO and accuracy enhancements of the wind-measuring equipment provide an equivalent level of safety;

(4)the operating techniques; and

(5)the operation of any systems that have an adverse effect on the VCA performance.
