The Instrument Panel
The instrument panel is located at the bottom of the screen. The missile-lock radar is located in the center of the instrument panel, and the long-range radar is to the right.
Use the long-range radar to locate enemy jets and the refueling tanker when they are not visible on the screen. The small dot in the middle of the radar screen marks the location of the jet. Enemy jets will appear in front of or behind your jet.
The fuel gauge is shown to the left of the missile-lock radar. When you are low on fuel, the gauge will begin to flash and you will hear a warning tone. You must reach the tanker and refuel before your fuel runs out completely.
The number of lives you have left is shown in the lower left-hand corner of the instrument panel. The number of rounds you have left in your machine gun is shown on the right.
The weapon you have selected is shown at the top of the screen, just below the score.
One-Player Games
In one-player games, the pilot controls both the firing of weapons and the jet's flight. Press the fire button on the left controller to fire the selected weapon. To increase your jet's speed, hold down the fire button on the right controller.
NOTE: When the currently selected weapon runs out of ammo, it will automatically change to the next available weapon. Move the right directional control if you wish to select a different weapon.
Two-Player Games
In two-player games, the flight officer uses the left controller to fly the ship. The weapons officer uses the right directional control to select weapons and the right fire button to fire them.
Weapons
Your jet starts out equipped with five guided missiles and about 2550 rounds of machine gun ammunition. In Missions 3, 4 and 5, your jet also carries three proximity missiles.
Guided Missiles
If you wish to fire guided missiles, you must change your weapon selection. Move the right controller to the left. Your missiles remaining display across the top of the screen.
The primary function of guided missiles is to destroy enemy bombers. When an enemy jet is within range, the missile-lock radar will turn bright blue and you will hear a beeping tone. Steer your jet until the locked-on enemy jet is in the cross-hairs. The missile-lock radar will then turn deep-red, and you will hear a steady tone. Fire your missile immediately to destroy the enemy jet.
NOTE: When an enemy jet is not within range, the missile-lock radar will be light blue if the jet is in front of you and violet if the jet is behind you.
