ATSA Dial Reading and Gauge Interpretation 3

Question 1

A DME (Distance Measuring Equipment) shows 45 nautical miles to a VOR. The aircraft travels at 270 knots groundspeed. In how many minutes will it reach the VOR?

Accepted Answer

10 minutes

Answer

At 270 knots (4.5 NM/min), covering 45 NM takes exactly 10 minutes.

Question 2

A barometric altimeter is set to 29.92 inches Hg. ATC instructs the pilot to set 29.75 inches Hg. Which direction will the indicated altitude change?

Accepted Answer

Decrease

Answer

Lowering the altimeter setting decreases the indicated altitude reading on the instrument.

Question 3

A radar return shows an aircraft at FL350 descending to FL200. The aircraft has traveled through 10,000 feet of the descent. What is the remaining descent in feet?

Accepted Answer

15,000 feet

Answer

FL350 to FL200 is 15,000 feet total; after descending 10,000 feet, 15,000 feet remain... wait — total is 15,000, minus 10,000 descended = 5,000 remaining.

Question 4

An oil pressure gauge reads 85 PSI. Normal range is 60–90 PSI. Is the reading within normal limits?

Accepted Answer

Yes, within normal range

Answer

85 PSI falls between the normal range of 60–90 PSI, so the reading is within normal limits.

Question 5

A heading indicator drifts 3 degrees per hour. After 2.5 hours of flight, how much drift has accumulated?

Accepted Answer

7.5 degrees

Answer

Multiplying 3 degrees per hour by 2.5 hours gives 7.5 degrees of accumulated drift.
