use typical flight manual information to determine:
(i)             time/distance/fuel used to a given altitude, or altitude reached after a given time or distance.
3.3.2              Cruise and descent:
(a)           given appropriate initial data, including variations from ISA, use typical flight manual information to determine, under normal and engine-out conditions:
(i)             maximum and optimum cruise levels;
(ii)            TAS and fuel consumption at specified altitudes, adjusting for use of bleed air, etc., as required;
(iii)          maximum weight or temperature at which specified performance and/or altitudes can be attained;
(iv)          holding speeds and fuel consumption at specified and optimum altitudes;
(v)           appropriate descent points and calculate time on descent.

(ii)            fuel weight, payload;
(c)           understand the consequences of overloading on:
(i)             take-off performance;

4.3                    Practical application
4.3.1              Use typical flight manual information to extract weight and balance data:
(a)           given appropriate initial data, determine any or all of:
(i)             CG at empty weight;
(ii)            movement of CG with addition of fuel and payload;
(iii)          movement of CG due to fuel consumption in flight;
(iv)          effect on CG of raising/lowering undercarriage;
(b)           determine CG limits for take-off, cruise and landing;
(c)           determine adjustments (if any) required to the payload to permit operations within the CG envelope.
4.3.2              Given appropriate initial data, assess a completed weight and balance proforma and determine whether it is acceptable for flight.
4.3.3              Sling load/hoist:
(a)           effects on CG.
