All right, let's pick this up right where the regulation is getting specific — Page 1, Lesson 7

All right, let's pick this up right where the regulation is getting specific. We've just established that when we don't weigh passengers individually, we use standard mass values. Now I want to walk you through exactly which values to use and the conditions that govern them. First, a critical timing rule. If you are weighing passengers, that weighing must be conducted immediately prior to boarding, and it must be done at a location adjacent to the boarding point. So it's not something you do an hour before at the check-in desk; it has to be right there, right before they step on the aircraft. Now, the standard mass values themselves. These are the figures we use when we are not weighing. And here's a key detail: the standard masses already include hand baggage. They also include the mass of any infant below two years of age who is being carried by an adult on one passenger seat. So if an adult is holding a baby on their lap, that baby's mass is already built into the adult's standard figure. But—and this is an important contrast—if an infant occupies their own separate passenger seat, then for the purpose of this regulation, that infant must be considered as a child. So they get the child's mass value, not the adult's. Now let's look at the actual values, and they depend on the size of the aeroplane. We're dealing with aeroplanes that have 20 or more passenger seats. For these, we use the male and female standard masses from Table 1. But there's an alternative: if the total number of passenger seats available is 30 or more, you may use the "all adult" mass values instead. So the 30-seat threshold gives you the option to use a single value for everyone rather than splitting by gender. Let me read you Table 1, because the numbers matter. For all flights except holiday charters, with 20 or more seats, the male standard mass is 88 kilograms, and the female is 70 kilograms. For holiday charters, the male is 83 kilograms and the female is 69 kilograms. Now, for the "all adult" values, which apply only when you have 30 or more seats, all flights except holiday charters use 84 kilograms, and holiday charters use 76 kilograms. And children, regardless of the flight type, are 35 kilograms. Now, what is a holiday charter? The regulation defines it precisely: it means a charter flight solely intended as an element of a holiday travel package. And there's a condition attached. The holiday charter mass values apply only provided that not more than 5% of the passenger seats installed in the aeroplane are used for the non-revenue carriage of certain categories of passengers. So if more than 5% of your seats are occupied by non-revenue passengers—like crew travelling on duty or company staff—then you cannot use the holiday charter figures; you must fall back on the standard all-flights values. So the logic here is: the holiday charter masses are lower because those passengers typically carry less baggage, but that assumption only holds if the vast majority of seats are revenue passengers on a genuine holiday package. The 5% cap protects that assumption. That's the complete picture for passenger standard masses on aeroplanes with 20 or more seats. The key contrasts to remember are the 20-versus-30 seat threshold, the male-versus-female versus all-adult options, the holiday charter versus all-flights distinction, and the infant-on-lap versus infant-in-own-seat rule.
