mass and balance

[filmarik]

hi folks,
plase could anybody help me with those to Q?

The operator of an aircraft equipped with 50 seats uses standard masses for passengers and baggage. During the preparation of a scheduled flight a group of passengers present themselves at the check-in desk, it is apparent that even the lightest of these exceeds the value of the declared standard mass.

A the operator may use the standard masses for the balance but must correct these for the load calculation

B the operator may use the standard masses for the load and balance calculation without correction

C the operator should use the individual masses of the passengers or alter the standard masss

D the operator is obliged to use the actual masses of each passenger


AND

The maximum zero-fuel mass:
1- is a regulatory limitation
2- is calculated for a maximum load factor of +3.5 g
3- is due to the maximum permissible bending moment
at the wing root
4- imposes fuel dumping from the outer wings tank first
5- imposes fuel dumping from the inner wings tank first
6- can be increased by stiffening the wing
The combination of correct statements is:

A

1, 2, 3

B

1, 3, 5

C

2, 5, 6

D 4, 2, 6


Thanks a lot
