Define and identify, on a diagram of the earth:
(a) great circles; - correct answer...✔✔Great circles are ones whose planes pass
through 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.
Define and identify, on a diagram of the earth:
(b) small circles; - correct answer...✔✔Small circles are circles on the surface on the
earth that do not pass through the centre of the earth. Parallels of latitude other than the
equator are all small circles.
Define and identify, on a diagram of the earth:
(c) rhumb lines; - correct answer...✔✔A rhumb line is a regularly curved line on the
earths surface that cuts all meridians at right angles.
Define and identify, on a diagram of the earth:
(d) parallels of latitude; - correct answer...✔✔Parallels of lattitude are small circles
(except the equator) that start at 0 deg at the equator and extend to 90 deg N at the
north pole and 90 deg S at the south pole.
Define and identify, on a diagram of the earth:
(e) meridians of longitude; - correct answer...✔✔All meridians of longitude are great
circles that pass through the north and south poles as well as the centre of the earth.
They start at 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.

, 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.
(c) kilometre - correct answer...✔✔A kilometre is not often used for aeronautical
distances. The length of a km is 1/10,000th of the distance between the equator and
either pole.
1 kilometre equates to:
- 3,280 feet
- 0.54 nautical miles
- 0.62 statute miles
18.8.2 Define:
(a) a knot (kt); - correct answer...✔✔A unit of airspeed equivalent to 1 nautical mile per
hour.
18.8.2 Define:
(c) indicated airspeed (IAS); - correct answer...✔✔The speed value indicated on the
airspeed indicator.
18.8.2 Define:
(d) calibrated airspeed (CAS); - correct answer...✔✔The indicated airspeed corrected
for instrument error and pressure error.
