(4) Calculation of the amount of ballast necessary for engine installation. It is considered that engines are installed in the open air, with peak windspeed of 45 kts (83 km/h). The ballast, if necessary shall be installed in the forward cargo-compartment at position 11.
(a)
Continue line B'F until it cuts across the 45 kts (83 km/h) average windspeed line at point H.
(b)
Continue vertical line FE' until it cuts across the "ballast on section 11" scale at point G.
(c)
From point G, make a horizontal line wich cuts across the
vertical line from H at point J.
(d)
Count the number of divisions on the scale between point G and J (in the example 2 division). Thus, weight of ballast necessary: 2 x 500 kg (1102.3110 lb) = 1000 kg (2204.6220 lb) In the same way, the amount of ballast necessary at cabin door No 1 is, in the given example:
1.5 x 500 kg (1102.3110 lb) = 750 kg (1653.4665 lb)
NOTE : As the ballast causes only a small increase in the
____ aircraft weight, this weight increase has been ignored.

NON-REVENUE FLIGHT - REQUIREMENTS FOLLOWING MAINTENANCE ACTIONS
_______________________________________________________________ DESCRIPTION AND OPERATION
_________________________
1. General
_______ Non-revenue flight following maintenance actions are not required by AIRBUS INDUSTRIE except for actions involving items that cannot be properly ground tested to verify that the aircraft's operational characteristics have not been adversly affected. Service experience has shown that a non-revenue flight is good practice following actions or repairs which could affect the aircraft's inherent aerodynamic characteristics.
NOTE : Operaters Regulatory Authority may require non-revenue flights
____
following certain maintenance actions.
2. Engine Replacement
__________________ Replacement or reinstallation of both engines does not require a non-revenue flight providing the engines have been successfully shop tested prior to installation, properly installed and successfully ground tested in accordance with all applicable maintenance instructions. However, owing to the number of different interfaces concerned, AIRBUS INDUSTRIE recommends that a non-revenue flight be carried out after changing or installing both engines to check that no double maintenance induced faults have been introduced.
