Question 1

E6B reading

Answer 1

Outside - Distance (distance on maps is always NM)

Inside - Time

GS = ground speed

To find ground speed (knots):

• Fund distance in NM (convert)
• Align time given to distance
• Find the big triangle, at a zero to the outer circle and that is your ground soeed in knots

Question 2

When to use 36sec index

Answer 2

When the distance is less than 1/10th of the groundspeed

If GS is 100knots and distance is .5NM, use 36sec index. Read time in SECONDS (think of where the decimal is)

Question 3

True airspeed

Answer 3

• Line up temperature with correct pressure alt.

- CAS is on the inside, find TAS on outside

Question 4

Wind and course

Answer 4

Grommet on the clear portion indicates GROUND SPEED and not TAS

Wind Vectors:

1) Wind Direction
2) Wind Speed
3) True Course
4) Ground Speed
5) Drift Correction (find on E6B)
6) True Air Speed
