- The Airbus A350 from Manila bound for St. Petersburg cannot travel in a straight route due to weather disturbances and some restrictions in the air space. Instead, it travelled at a velocity of 740 kph due 25° NNE, then it turned towards East at a velocity of 870 kph. After that, at a velocity of 900 kph, it ventured 35° WNW, then it turned 50° South of West maintaining the same velocity of 900 kph. Finally, to reach its destination, it needs to turn towards west at a velocity of 350 kph.
