CAA ORS9 Decision No. 15
MASS VALUES FOR PASSENGERS AND BAGGAGE
(a) When the number of passenger seats available is:
(1) less than 10 for aeroplanes; or
(2) less than 6 for helicopters,
passenger mass may be calculated on the basis of a statement by, or on behalf of, each passenger, adding to it a predetermined mass to account for hand baggage and clothing.
The predetermined mass for hand baggage and clothing should be established by the operator on the basis of studies relevant to his particular operation. In any case, it should not be less than:
(1) 4 kg for clothing; and
(2) 6 kg for hand baggage.
The passengers’ stated mass and the mass of passengers’ clothing and hand baggage should be checked prior to boarding and adjusted, if necessary. The operator should establish a procedure in the operations manual when to select actual or standard masses and the procedure to be followed when using verbal statements.
(b) When determining the actual mass by weighing, passengers’ personal belongings and hand baggage should be included. Such weighing should be conducted immediately prior to boarding the aircraft.
(c) When determining the mass of passengers by using standard mass values, the standard mass values in Tables 1 and 2 below should be used. The standard masses include hand baggage and the mass of any infant carried by an adult on one passenger seat. Infants occupying separate passenger seats should be considered as children for the purpose of this AMC. When the total number of passenger seats available on an aircraft is 20 or more, the standard masses for males and females in Table 1 should be used. As an alternative, in cases where the total number of passenger seats available is 30 or more, the ‘All Adult’ mass values in Table 1 may be used.

(*) Holiday charter means a charter flight that is part of a holiday travel package. On such flights the entire passenger capacity is hired by one or more charterer(s) for the carriage of passengers who are travelling, all or in part by air, on a round- or circle-trip basis for holiday purposes. The holiday charter mass values apply provided that not more than 5 % of passenger seats installed in the aircraft are used for the non-revenue carriage of certain categories of passengers. Categories of passengers such as company personnel, tour operators’ staff, representatives of the press, authority officials, etc. can be included within the 5% without negating the use of holiday charter mass values.

(1) On aeroplane flights with 19 passenger seats or less and all helicopter flights where no hand baggage is carried in the cabin or where hand baggage is accounted for separately, 6 kg may be deducted from male and female masses in Table 2. Articles such as an overcoat, an umbrella, a small handbag or purse, reading material or a small camera are not considered as hand baggage.
(2) For helicopter operations in which a survival suit is provided to passengers, 3 kg should be added to the passenger mass value.
(d) Mass values for baggage
(1) Aeroplanes. When the total number of passenger seats available on the aeroplane is 20 or more, the standard mass values for checked baggage of Table 3 should be used.
(2) Helicopters. When the total number of passenger seats available on the helicopters is 20 or more, the standard mass value for checked baggage should be 13 kg.
(3) For aircraft with 19 passenger seats or less, the actual mass of checked baggage should be determined by weighing.

(4) For the purpose of Table 3:
(i) domestic flight means a flight with origin and destination within the borders of one State;
(ii) flights within the European region mean flights, other than domestic flights, whose origin and destination are within the area specified in (d)(5); and
(iii) intercontinental flight means flights beyond the European region with origin and destination in different continents.
(5) Flights within the European region are flights conducted within the following area:
N7200 E04500
N4000 E04500
N3500 E03700
N3000 E03700

as depicted in Figure 1.

(e) Other standard masses may be used provided they are calculated on the basis of a detailed weighing survey plan and a reliable statistical analysis method is applied. The operator should advise the CAA about the intent of the passenger weighing survey and explain the survey plan in general terms. The revised standard mass values should only be used in circumstances comparable with those under which the survey was conducted. Where the revised standard masses exceed those in Tables 1, 2 and 3 of, then such higher values should be used.
(f) On any flight identified as carrying a significant number of passengers whose masses, including hand baggage, are expected to significantly deviate from the standard passenger mass, the operator should determine the actual mass of such passengers by weighing or by adding an adequate mass increment.
(g) If standard mass values for checked baggage are used and a significant number of passengers checked baggage is expected to significantly deviate from the standard baggage mass, the operator should determine the actual mass of such baggage by weighing or by adding an adequate mass increment.
