In the following year, the flying boat was awarded first prize after passing every single test during a high-profile commercial seaplane contest.

Its performance was quite positive, passing every single test conducted without any failures or need for repairs, leading to it being awarded first prize.

[8] During 1927, it carried out a series of operational-standard test flights on the non-stop Marseilles to Algiers route; its manufacturers being keen to see the type establish a regular service between France and North Africa.

[8] The Météore 63 was a biplane flying boat that had a relatively conventional configuration for the era, consisting of a single hull along with single-bay wings of unequal span.

[4][8] The majority of the structure was composed of timber except for the struts used to carry the flying boat's three engines, which were made of steel tubing instead.

[8] The hull, which had only a single step and was relatively sturdy, was deemed to be suitable for alighting on the open ocean, bolstering the flying boat's safety during lengthy water crossings.

[10] The hull was divided into a series of watertight compartments, two of which may be fitted out for the carriage of passengers, light freight, packages and air mail.

Furthermore, the mounting of the engines, in a transversal arrangement between the wings, meant that virtually all vibrations they produced during normal operations were eliminated.

[13] Typically, the flying boat carried sufficient fuel to permit a flight time of seven hours with the engines held at a constant cruising speed.

[8] The same year, Lignes Aériennes Latécoère trialled the type on a mail route between Marsailles and Algiers,[8] the first trip taking place on 22 October.

[4][15] In October that year, Maurice Noguès flew it from Marsailles to Beirut but crashed and sank off Naples during the return journey.
