FEAST Spatial Orientation and Reasoning 2

Question 1

An aircraft at position N52° E004° is flying heading 090 at 400 kts groundspeed. After 15 minutes, its approximate longitude will be:

Accepted Answer

E006° — the aircraft has moved east approximately 2° of longitude at N52°

Answer

E004° — the aircraft hasn't moved because heading 090 is parallel to the equator

Answer

E007° — moved 3° east

Answer

E003° — the aircraft moved west because heading 090 at N52° curves poleward

Question 2

A radar display shows an aircraft track heading towards you from the east at a steady 5-mile-per-sweep rate. The track will be at your position in approximately:

Accepted Answer

The time it takes depends on the sweep rate — but at 6 seconds per sweep, 5 NM per sweep means 360 NM/min closure

Answer

Exactly 1 minute because standard ATC radar sweeps once per 12 seconds

Answer

5 minutes because the aircraft is 5 miles away

Answer

30 seconds regardless of sweep rate

Question 3

Two aircraft are at the same altitude. Aircraft Uniform is at N51° E003°, heading 045. Aircraft Victor is at N53° E006°, heading 225. On what heading are the two aircraft flying relative to each other, and are they converging or diverging?

Accepted Answer

Reciprocal headings (045/225) — they are converging directly toward each other

Answer

Parallel headings — they are flying at the same angle and not converging

Answer

Perpendicular headings — they will cross at right angles

Answer

They are diverging because the northbound aircraft is moving away

Question 4

An aircraft is given a heading change from 360 to 090. It turns right. How many degrees has it turned, and in which direction was the turn?

Accepted Answer

90 degrees to the right — from north (360) to east (090) is a 90-degree right turn

Answer

270 degrees to the right — the long way around

Answer

90 degrees to the left — the most efficient route from 360 to 090

Answer

270 degrees to the left — completing a near-full circle

Question 5

On a radar display, an aircraft is at bearing 270 (due west) from a VOR beacon at 20 NM. Another aircraft is at bearing 090 (due east) from the same VOR at 15 NM. Both are at the same altitude. The distance between them is approximately:

Accepted Answer

35 NM — they are on opposite sides of the VOR on the same east-west line

Answer

25 NM — only the longer radial matters

Answer

5 NM — the difference of the two distances

Answer

20 NM — average of the two distances

Question 6

An aircraft is flying a standard rate turn (3 degrees per second). It takes approximately how long to complete a 180-degree turn?

Accepted Answer

60 seconds — 180 degrees ÷ 3 degrees per second = 60 seconds

Answer

30 seconds — half of 180 is 90 seconds which is halved

Answer

90 seconds — 180 ÷ 2 degrees per second

Answer

120 seconds — a full turn takes 240 seconds so half is 120 seconds
