Cavani missed a golden chance four minutes from time when a fallen defender allowed him a one-on-one chance with Al-Owais at the top of the box but Saudi keeper did well to get a foot on the PSG man's effort and keep it out.
Despite the incident, the aircraft was able to land safely and the team are continuing their preparations for their group game against Uruguay on Wednesday.
Saudi Arabia put up more of a fight than they had in their opening 5-0 defeat to Russian Federation but struggled to test Fernando Muslera in the Uruguay goal.
It was a momentous day for Luis Suarez - the forward earned his 100th cap for Uruguay and he crowned the occasion with a goal.
Anyway, he was off his game in the first match and Uruguay as a whole were so-so against Egypt, needing a late victor from Jose Gimenez to win by the single goal.More news: Two killed & 4 injured in mass shooting in Malmo, Sweden
At least Suarez, who missed three sitters in Uruguay's 1-0 opening win against Egypt, was his vintage efficient self with his 52nd worldwide goal although he will not have dismissed fears he was not 100 percent fit.
Muslera will also tie Ladislao Mazurkiewicz as the player to have made the most appearances for Uruguay at a World Cup.
The Saudis managed to have plenty of early possession, although without looking overly threatening, only to gift Uruguay a 23rd-minute lead.
"If I've learned one thing from being at the World Cup it's that anything can happen".
They suffered a setback shortly before the interval as veteran Taisir Al-Jassim was replaced by Housain Al-Mogahwi with an apparent thigh injury.
