X-C Flight Planning - B: Flight computers and Basic Calculations

Question 1

TDS1: If time equals 25 minutes and distance equals 47 NM, what is your speed?

Answer 1

113 KTS (S=D/T)

Question 2

TDS2: If Distance equals 84 NM and Speed = 139 KTS, what will the time be?

Answer 2

36 minutes (T=D/S)

Question 3

TDS3: If Speed is 85 KTS and time is 51 Minutes, what is the Distance covered?

Answer 3

72 NM (D=SxT)

Question 4

FC1: if GPH is 9.3 and time is 1 Hour, 27 minutes, how many gallons will be consumed?

Answer 4

13.5 Gallons (FC = T x GPH): 1.45 x 9.3 = 13.5

Question 5

FC2: If time is 2 hours, 13 minutes and gallons consumed is 32, what is GPH?

Answer 5

14.5 (GPH = GPH / Time): 32/2.2 = 14.54

Question 6

FC3: If Gallons consumed is 38 and GPH is 10.8, what will time be?

Answer 6

3h, 31m (T = FC/GPH): 38 / 10.8 = 3.52

Question 7

TAS1: If Alt = 10,000ft, temp = 0c, and IAS = 115, what is TAS?

Answer 7

135 (use E6B or whiz wheel)

Question 8

TAS2: If Alt=9,500, IAS = 103, and Temp = -10c, what is TAS?

Answer 8

118 (use E6B or Whiz Wheel)

Question 9

DA1: PA = 1,500, TEMP = 35C. What is DA?

Answer 9

4,100 (Use E6b or Whiz Wheel)

Question 10

DA2: PA=5,000, Temp = -10c, What is DA?

Answer 10

3148 (Use E6b or Whiz Wheel)

Question 11

DA3: PA=2,000, Temp = 30c, What is DA?

Answer 11

4163 (Use E6b or Whiz Wheel)

Question 12

7Qts oil ways how much?

Answer 12

13.125 (1.875 lbs/qt x 7)

Question 13

20 KTs equals how many MPH?

Answer 13

23 (1.15 x KIA)

Question 14

GS/TH1; Wind is 220 @ 30, TC = 146, TAS = 165. What is GS and TH?

Answer 14

GS = 124, TH = 158, WCA = +12

Question 15

GS/TH2: Wind = 240 @ 25, TC = 283, TAS = 165. What is GS and TH?

Answer 15

GS = 146, TH = 277, WCA = -6

Question 16

GS/TH3: Wind = 060 @ 30, TC = 036, TAS = 140. What is GS and TH?

Answer 16

GS = 112, TH = 41, WCA = +5

Question 17

After Takeoff, you attempt to activate you VFR flight plan but are unable to contact the FSS. What will happen to your filed flight plan?

Answer 17

Plan remains active until activation, or for 1 hour following estimated departure time. After that it is cancelled.

Question 18

Diversion/Alt1: What actions should be taken if you become disoriented or lost on a X-Country flight (NO GPS AVAILABLE)

Answer 18

5 C’s:
1. Climb - better visibility, better radio range
2. Circle - don’t make things worse by continuing in an unfamiliar direction
3. Communicate - Approach, Center, tower. Use 121.5 if no results on others
4. Confess - let them know your problem
5. Comply with instructions

Question 19

During a X-Country flight, weather has deteriorated, and you must Divert to an alternate Airport. Assuming no GPS and NO DME available, how will you navigate to the alternative?

Answer 19

1. Call the Tower and ask for vectors
2. Call approach or control and ask for Vectors
3. User localizer or Triangulate using VOR
4. Use Chart - Plot approx Mag course from nearby VOR compas rose or flyway
5. Dead-reckon your way based on chart
