6.22.4(b) Aerodrome Chart.
Aerodrome charts are published in the AIPNZ Volume 4 (link below)
These charts contain detailed information on many of the New Zealand aerodromes, including information such as frequencies, runway lengths, runway conditions and much more.

Calculate ETD and ETA in UTC given planned flight time details and reference time in NZST andor NZDT.
To work out ETD, first we must convert our time of departure to UTC. Depending on the time of year, we would either subtract 12 or 13 hours (NZST / NZDT) from our time to get our ETD in UTC.
To work out our ETA, first we must work out how long the flight will take to travel the distance with the given ground speed on the day, then add this time to our time of departure. We can then subtract the 12 or 13 hours to convert NZST or NZDT to UTC.
6.14.2(c) Head/tail wind;
A Head wind or Tail wind requires the aircraft to be flown either into the wind or away from it.
With a tail wind, we are pushed from behind, therefore flying faster over the ground.
With a head wind, with have to fly against the wind, being pushed backwards, therefore flying slower over the ground.
6.12.2(c) Mean sea level (MSL);
MSL is the sea level halfway between the mean levels of high and low tide.
6.10.2(c) Fix;
A fix is the geological position of an aircraft at a specific time determined by visual reference to ground features or reference to navigation aids.
6.8.2(c) Indicated Airspeed (IAS);
Indicated airspeed (IAS) is the airspeed read directly from the airspeed indicator in the aircraft, displayed in knots.
It uses the difference between total pressure and static pressure, to calculate a speed through the air
6.6.2(e) Foot.
A foot is a unit of length defined as being 0.3048 m exactly.
A foot is made up of 12 inches.
It is the primary unit of indicating height in aviation.
Its symbol is ft
The Earth is essentially a large magnet with a field of magnetic force around it. The Earth’s magnetic poles are not situated at the same positions as the geographical poles.Â
The North magnetic pole is located in Hudson bay, Canada and the South magnetic pole over Antarctica.Â
Magnetic North Pole
Â
Any magnet free from interference will align with the earth’s magnet fields.Â
Thus a free magnet, with have “Magnetic dip” and a “variation from true north”.
Magnetic dip is the angle that a magnetic needle makes with the horizontal plane at any specific location.Â
Magnetic dip varies at different points on the Earths surface, at the magnetic equator the dip is 0 degrees; and 90 degrees at each of the magnetic poles.
Magnetic Variation
this variation is primary due to the differing location of the geographical poles and the magnetic poles.
Isogonal lines …
on a map, these are lines connecting all points of equal magnetic Variation
You can see from the map that the 20° east run through New Zealand.
The north-seeking end of the magnetic / aircraft compass pointe to Magnetic North.

6.2.4(b) Define and identify on a diagram of the Earth: Geographic and Magnetic Poles
Â
Geographic poles are at each of the two points; the North Pole and the South Pole on the surface of a rotating planet, the line between them forms the rotational axis.
