5 Add the times to get the answer of 26.8 minutes. 35. Convert liters per minute to gallons per hour. 1.6 lpm =.423 gal per min = 25.4 gph So you are burning 25.4 gph for 26.8 minutes, which is 11.3 gal. Subtract 11.3 from the 73 gal you started with to get 61.7 gal. Convert to 369 lbs. 36. First use the following equation to find the groundspeed. fpm / fpnm = GS / / 230 = GS / 60 GS = 133 knots Mark wind dot and put TC under True index. Put the grommet over the GS of 133 knots. You will find the TAS of 150 knots under the wind dot. On calculator side put TAS of 150 knots over CAS of 131 knots. Find 10 C in the airspeed window and it will be aligned with the answer of 8000 feet. 37. First find PA. Standard altimeter is hpa = 25.4 Pressure reduces hpa per 1000 feet. (25.4 / 33.86) 1000 = 750 feet. So PA is 750 ft. lower than cruising altitude. PA is 6750 ft. Align PA of 6750 ft. with OAT of -20 C to find answer of 4100 ft. 38. First find GS. Flying.9 NM in 17 seconds is 191 knots. Now, flying 146 NM at 191 knots will take 45.9 minutes. Burning fuel at 10.4 gph for 45.9 min equals the answer of 8.0 gal. 39. Simple TSD to find speed of 144 mph. Accepted As Correct: mph 40. Simple temperature conversion to find 5 C. Accepted As Correct: 4.5 C 5.5 C 41. Simple conversion to find 372 pounds. Accepted As Correct: pounds 42. Refer to calculator side. Note 178 on outside scale. Turn inside scale until the same number appears under 178 and over the 10 of the inside scale. This alignment occurs twice on the scale, opposite each other: and Pick the one that makes sense for the given number. We know = 100, so we know it s slightly more than 10. It s definitely not 42.19, so is the correct choice. If you were asked the square root of 1780 the answer would be The correct choice alternates back and forth as the decimal place of the given number moves. Accepted As Correct: There are 6076 per NM. Convert 4300 feet per minute to.71 NM per minute. Multiply this by 60 to find the answer of 42.5 knots. Accepted As Correct: knots 44. Simple weight conversion to find 109 kg. Accepted As Correct: kg 45. There are 4 quarts per gallon. There are 36 quarts which is 9 gal of oil. Convert 9 gal of oil to the answer of 67.5 pounds. Accepted As Correct: pounds 5
