SUBPART F PERFORMANCE GENERAL U.K.

OPS 1.475 General U.K.

(a)

An operator shall ensure that the mass of the aeroplane:

(1)

At the start of the take-off;

or, in the event of in-flight replanning

(2)

At the point from which the revised operational flight plan applies,

is not greater than the mass at which the requirements of the appropriate Subpart can be complied with for the flight to be undertaken, allowing for expected reductions in mass as the flight proceeds, and for such fuel jettisoning as is provided for in the particular requirement.

(b)

An operator shall ensure that the approved performance Data contained in the Aeroplane Flight Manual is used to determine compliance with the requirements of the appropriate Subpart, supplemented as necessary with other data acceptable to the Authority as prescribed in the relevant Subpart. When applying the factors prescribed in the appropriate Subpart, account may be taken of any operational factors already incorporated in the Aeroplane Flight Manual performance data to avoid double application of factors.

(c)

When showing compliance with the requirements of the appropriate Subpart, due account shall be taken of aeroplane configuration, environmental conditions and the operation of systems which have an adverse effect on performance.

(d)

For performance purposes, a damp runway, other than a grass runway, may be considered to be dry.

(e)

An operator shall take account of charting accuracy when assessing compliance with the take-off requirements of the applicable subpart.]
