Grand Theft Auto: San Andreas/Las Venturas Airport Race Tournament

Unlike street races you do not race against other competitors here and neither is there a time limit. The sole purpose is to complete the course by passing through (or rather touching) the red coronas without crashing the plane. Each race carries a $10,000 prize for completing it.

World War Ace

 * Vehicle: Rustler

Barnstorming

 * Vehicle: Stuntplane

If you didn't get all Silver/Gold in Flying School, this is a way to get your hands on Stuntplane. Start the race, fly to Verdant Meadows airstrip, and store it in the plane hall.

Military Service

 * Vehicle: Hydra

Chopper Checkpoint

 * Vehicle: Maverick
 * Course: Over Tierra Robada

You don't need to pass through the coronas, so with a helicopter, you can simply hover above the corona, and descend straight down until the helicopter touches the corona. This will cost you time, but since there is no time limit or competitors, you will get the prize anyway.

Whirly Bird Waypoint

 * Vehicle: News Chopper
 * Course: Over San Fierro

You don't need to pass through the coronas, so with a helicopter, you can simply hover above the corona, and descend straight down until the helicopter touches the corona. This will cost you time, but since there is no time limit or competitors, you will get the prize anyway.

In addition, if you for some reason want a news chopper (a regular Maverick with different texture), this is a way to get one. Start the race, fly to Verdant Meadows airstrip, and store it in the plane hall.

Heli Hell

 * Vehicle: Hunter
 * Course: Over Los Santos

You don't need to pass through the coronas, so with a helicopter, you can simply hover above the corona, and descend straight down until the helicopter touches the corona. This will cost you time, but since there is no time limit or competitors, you will get the prize anyway.

In addition, if you didn't get all Gold in Flying School, this is a way to get your hands on Hunter. Start the race, fly to Verdant Meadows airstrip, and store it in the plane hall.

Rewards
Each race won earns you $ 10 000. When you win the last race of all four tournaments (whichever it is), you get a $ 1 000 000 prize.
