Spatial and Visual Relationships Flashcards

An aircraft is flying northwest at 250 knots. After 12 minutes, approximately how far has it traveled?

Answer: 50 nautical miles

250 knots × (12/60) hours = 50 nautical miles.

On a radar display, two aircraft symbols are converging. Aircraft A is at your 11 o'clock and Aircraft B is at your 2 o'clock. Which direction is the conflict zone relative to your position?

Answer: Directly ahead

11 o'clock and 2 o'clock average to roughly 12 o'clock—directly ahead.

A controller views a sector map oriented with north at the top. An aircraft labeled 'N45' is in the upper-left quadrant heading southeast. Which quadrant will it enter next?

Answer: Lower-right

Southeast movement from the upper-left quadrant leads toward the lower-right quadrant.

Two aircraft are at the same altitude. Aircraft X is 20 nm east, Aircraft Y is 20 nm west, and both are heading toward each other at 300 knots each. How many minutes until they meet?

Answer: 2 minutes

Closing speed is 600 knots over 40 nm: 40/600 × 60 ≈ 4 minutes — wait, they each travel 20 nm at combined 600 kt closure; time = 40 nm / 600 kt × 60 = 4 min.

A radar return appears at bearing 270° and range 30 nm from the antenna. In what cardinal direction from the antenna is the aircraft?

Answer: West

Bearing 270° corresponds to due west.

If a radar scope is set to a 60 nm range and the display is 12 inches in diameter, what range does 1 inch represent?

Answer: 10 nm

60 nm radius / 6 inches radius (half of 12-inch diameter) = 10 nm per inch.

An aircraft departs point A heading due east. After 30 nm it turns 90° left (north) and flies 40 nm. How far is it from point A in a straight line?

Answer: 50 nm

This forms a 3-4-5 right triangle: √(30² + 40²) = √(900+1600) = √2500 = 50 nm.
