CPL Navigation Exam Questions With Correct
Answers
Define |and |identify, |on |a |diagram |of |the |earth:

the |centre |of |the |earth |and |splits |the |earth |into |two |equal |parts, |lines |of |meridians |with |their |
anti-meridian |form |a |great |circle. |The |equator |is |also |a |great |circle.

000 |deg |E/W |at |the |prime |meridian |and |travel |to |180 |deg |E/W |at |the |prime |meridians |anti-
meridian.
,Define |and |identify, |on |a |diagram |of |the |earth:
(f) |Greenwich |(Prime) |Meridian. |- |CORRECT |ANSWER✔✔-The |prime |meridian |is |the |meridian |
that |runs |through |Greenwich |and |is |located |at |000 |deg |E/W.
Define:
(a) |relative |bearing; |- |CORRECT |ANSWER✔✔-A |relative |bearing |is |the |bearing |of |an |object |
measured |clockwise |from |the |nose |of |the |aircraft.
Define:
(b) |back |bearing |- |CORRECT |ANSWER✔✔-Back |bearing |is |the |reciprocal |of |the |relative |bearing
|which |can |be |found |by |adding |or |subtracting |180 |deg.
18.4.4 |Explain |the |processes, |cautions |and |limitations |when |deriving |track |distances |and
bearings |from |a |chart. |- |CORRECT |ANSWER✔✔-To |avoid |problems |when |deriving |distances |
and |bearings |from |charts |it |is |important |to |do |the |following:
- |ensure |charts |are |the |latest |edition
- |ensure |the |correct |scale |ruler |is |used |for |the |chart
- |align |the |protractor |correctly |with |lat/long |lines
- |apply |variation |correctly
- |confirm |whether |the |bearing |is |'to' |or |'from' |an |object
18.6.2 |Define |the |various |units |of |distance |used |in |aviation |and |the |application |of |each.
(a) |Nautical |mile |- |CORRECT |ANSWER✔✔-A |nautical |mile |is |the |length |of |an |arc |on |a |great |
circle |that |equates |to |a |1-minute |angle |at |the |earths |centre. |A |1-degree |angles |will |equate |to |
a |60nm |arc.
1 |nautical |mile |equates |to:
- |1.15 |statute |miles
- |6076.12 |feet
, - |1.85 |kilometres
18.6.2 |Define |the |various |units |of |distance |used |in |aviation |and |the |application |of |each.
(b) |Statute |mile |- |CORRECT |ANSWER✔✔-Statute |miles |were |decreed |by |law |however |have |no |
practical |application |in |aeronautical |navigation. |1 |Statute |miles |equates |to:
- |5,280 |feet
- |0.87 |nautical |miles
- |1.6 |kilometres
18.6.2 |Define |the |various |units |of |distance |used |in |aviation |and |the |application |of |each.
