I was just thinking after reading another 747-8 thread would Boeing be doing a flight test with a full load of passengers like Airbus did with the A380? Why did Airbus even need to to do such a test for? I had never heard of such a thing before this. Would Boeing even need to do such a test because the 747-8i isn't a completely new aircraft? Thank you for your your feedback and info.

Quoting legacyins (Reply 1): One reason is that they need to certify they they evacuate an aircraft in a certain time during an emergency.
I'm not sure that test is done in flight.
I suspect such tests are more to do with checking the general views and reactions of people who haven't been involved in the development so are less likely to be impaired by tunnel-vision. Having some journalists on board doesn't do any harm, as long as there are no major problems, of course.

The 747-8 does not need to perform an emergency evacuation test. The passenger limit of the aircraft in three (or even two) classes is less than the capacity of the 747-100 in a single class so the aircraft can be grandfathered in under the original evacuation test.
I expect Boeing will (artificially) set the maximum certified capacity to be the same as the 747-100, so if a carrier does decide to operate on in a single class, it would probably be pretty nice since you'd have increased pitch.

Nowadays, Boeing uses its own employees for tests. With 80,000 employees in the Seattle area it is not hard to find enough people.
Also, so far none of the 748I's are in fully passenger configuration. They are still equipped with flight test equipment although the first plane for Lufthansa does have their new generation of business class seats installed.
If you have never designed an airplane part before, let the real designers do the work!

The 747-8 intercontinental has "grandfather evacuation rights" from the 747-400 series.
The 747-400 inherited these rights from the 747-300 (main +upper deck) and earlier series (100-200) for the main deck.
The actual main deck evacuation test were carried out on the 747-100 and later additional evacuation test were performed on the stretched upper deck of the first built 747-300. Both tests are still valid for the 747-8I.
Passenger evacuation limit is 550 passengers for the main deck (with 5 pair of type A exits) and 110 passengers for the upper deck (with one pair of type A exits) for the 747 series with a stretched upper deck (747-100BSUD, 300 and 400 series).
Max total capacity 660 passengers.
The 747-8 intercontinental will be certified with only 495 passengers on the main deck and 110 passengers on the upper deck. Max. total capacity 605 passengers.
