Not a great deal happening on Saturday although three locals that seldom see the daylight came out to play.
ZK-JRP Rans S-9 Chaos . C/n 0802174 . Rotax 503 powered onto a Warp Drive Prop
This is yet another Peter Dyer production. At least his ninth project.
His son is flying off the test program for this aircraft as Peter feels that he is getting too old.
ZK-WSS is Warren Shapcott's Zenair Zodiac CH-600 . c/n 6-1117
ZK-POP is a Ragwing Aero Special . c/n RWS086. Built by Barrie Gurdler & Bevin Chamberlain.
Now just with Bevin.
It originally had a cowling based on that of the Polikapov I-16 Rata.
The engine has now been moved forward and a more streamlined cowling is being worked on.
There has been no progress on assembling the Fleet.
PILOTAGE—Navigation by visual reference to landmarks.
PILOT'S OPERATING HANDBOOK (POH)—A document developed by the airplane manufacturer and contains the FAA-approved Airplane Flight Manual (AFM) information.
PILOT WEATHER REPORT (PIREP)A report, generated by pilots, concerning meteorological phenomena encountered in flight.

PNEUMATIC—Operation by the use of compressed air.
POOR JUDGMENT CHAIN—A series of mistakes that may lead to an accident or incident. Two basic principles generally associated with the creation of a poor judgment chain are: (1) One bad decision often leads to another; and (2) as a string of bad decisions grows, it reduces the number of subsequent alternatives for continued safe flight. ADM is intended to break the poor judgment chain before it can cause an accident or incident.
POSITIVE STATIC STABILITY— The initial tendency to return to a state of equilibrium when disturbed from that state.
POWER—Implies work rate or units of work per unit of time, and as such, it is a function of the speed at which the force is developed. The term, power required, is generally associated with reciprocating engines.
POWERPLANT—A complete engine and propeller combination with accessories.
PRECESSION—The tilting or turning of a gyro in response to deflective forces causing slow drifting and erroneous indications in gyroscopic instruments.
PRECIPITATION—Any or all forms of water particles (rain, sleet, hail, or snow), that fall from the atmosphere and reach the surface.

PRESSURE ALTITUDE—The altitude indicated when the altimeter setting window (barometric scale) is adjusted to 29.92. This is the altitude above the standard datum plane, which is a theoretical plane where air pressure (corrected to 15ºC) equals 29.92 in. Hg. Pressure altitude is used to compute density altitude, true altitude, true airspeed, and other performance data.
NOTICES TO AIRMEN (NOTAM)—A notice containing time-critical information that is either of a temporary nature or is not known far enough in advance to permit publication on aeronautical charts or other operation publications. This can include the establishment, condition, or change in any facility, service, procedure, or hazard in the National Airspace System.
OBSTRUCTION LIGHTS—Lights that can be found both on and off an airport to identify obstructions.
OCCLUDED FRONT—A frontal occlusion occurs when a fast-moving cold front catches up with a slowmoving warm front. The difference in temperature within each frontal system is a major factor in determining whether a cold or warm front occlusion occurs.
OUTSIDE AIR TEMPERATURE (OAT)—The measured or indicated air temperature (IAT) corrected for compression and friction heating. Also referred to as true air temperature.
OVERBOOST—A condition in which a reciprocating engine has exceeded the maximum manifold pressure allowed by the manufacturer. Can cause damage to engine components.

PAYLOAD (GAMA)—The weight of occupants, cargo, and baggage.
PERSONALITY—The embodiment of personal traits and characteristics of an individual that are set at a very early age and extremely resistant to change.
P-FACTOR—A tendency for an aircraft to yaw to the left due to the descending propeller blade on the right producing more thrust than the ascending blade on the left. This occurs when the aircraft's longitudinal axis is in a climbing attitude in relation to the relative wind. The P factor would be to the right if the aircraft had a counterclockwise rotating propeller.
PHUGOID OSCILLATIONS — Long-period oscillations of an aircraft around its lateral axis. It is a slow change in pitch accompanied by equally slow changes in airspeed. Angle of attack remains constant, and the pilot often corrects for phugoid oscillations without even being aware of them.
MOMENT—The product of the weight of an item multiplied by its arm. Moments are expressed in pound-inches (lb-in). Total moment is the weight of the airplane multiplied by the distance between the datum and the CG.
MOMENT ARM—The distance from a datum to the applied force.
MOMENT INDEX (OR INDEX)— A moment divided by a constant such as 100, 1,000, or 10,000. The purpose of using a moment index is to simplify weight and balance computations of airplanes where heavy items and long arms result in large, unmanageable numbers.
MONOCOQUE—A shell-like fuselage design in which the stressed outer skin is used to support the majority of imposed stresses. Monocoque fuselage design may include bulkheads but not stringers.
MONOPLANES—Airplanes with a single set of wings.
MOVABLE SLAT—A movable auxiliary airfoil on the leading edge of a wing. It is closed in normal flight but extends at high angles of attack. This allows air to continue flowing over the top of the wing and delays airflow separation.
N1—Rotational speed of the low pressure compressor in a turbine engine.
N2—Rotational speed of the high pressure compressor in a turbine engine.
NACELLE—A streamlined enclosure on an aircraft in which an engine is mounted. On multiengine propeller-driven airplanes, the nacelle is normally mounted on the leading edge of the wing.
NATIONAL SECURITY AREAS— Airspace that consists of defined vertical and lateral dimensions established at locations where there is a requirement for increased security and safety of ground facilities.
NDB—See NONDIRECTIONAL RADIO BEACON.
NEGATIVE STATIC STABILITY—The initial tendency of an aircraft to continue away from the original state of equilibrium after being disturbed.
NEUTRAL STATIC STABILITY— The initial tendency of an aircraft to remain in a new condition after its equilibrium has been disturbed.
NONDIRECTIONAL RADIO BEACON (NDB)—An L/MF or UHF radio beacon transmitting non directional signals whereby the pilot of an aircraft equipped with direction finding equipment can determine the bearing to or from the radio beacon and "home" on or track to or from the station. When the radio beacon is installed in conjunction with the Instrument Landing System marker, it is normally called a Compass Locator.
The Cessna 310P ZK-DTM/2, c/n 310P-0199, is still lurking about at Christchurch. It was parked in the helicopter compound today.
It is marked "Precision Aerial Surveys".
The Canterbury Aero Club new Piper PA-28-181 Cherokee Archer III , c/n 28-43638 , was listed as ZK-LJI on the first of the month. It however still carries its US N1005J marks.
At Wigram the Vans RV-4 ZK-SIM/2 , c/n 2826 , had just returned from a run to determine fuel flow rate. This machine was built in the US as N493DC and imported into NZ and registered here on 11-08-2005 to A T Sim. It is now with E D Langston.

MINIMUM EQUIPMENT LIST (MEL)—A list developed for larger aircraft that outlines equipment that can be inoperative for various types of flight including IFR and icing conditions. This list is based on the master minimum equipment list (MMEL) developed by the FAA and must be approved by the FAA for use. It is specific to an individual aircraft make and model.
LONGITUDE—Measurement east or west of the Prime Meridian in degrees, minutes, and seconds. The Prime Meridian is 0° longitude and runs through Greenwich, England. Lines of longitude are also referred to as meridians.
LONGITUDINAL AXIS—An imaginary line through an aircraft from nose to tail, passing through its center of gravity. The longitudinal axis is also called the roll axis of the aircraft. Movement of the ailerons rotates an airplane about its longitudinal axis.
LONGITUDINAL STABILITY (PITCHING)—Stability about the lateral axis. A desirable characteristic of an airplane whereby it tends to return to its trimmed angle of attack after displacement.
LORAN-C—A radio navigation system that utilizes master and slave stations transmitting timed pulses. The time difference in reception of pulses from several stations establishes a hyperbolic line of position, which can be identified on a LORAN chart. A fix in position is obtained by utilizing signals from two or more stations.
MAGNETIC BEARING—The magnetic course to go direct to an NDB station.
MAGNETIC COMPASS—A device for determining direction measured from magnetic north.
MAGNETIC DIP—Avertical attraction between a compass needle and the magnetic poles. The closer the aircraft is to the pole, the more severe the effect. In the Northern Hemisphere, a weight is placed on the south-facing end of the compass needle; in the Southern Hemisphere, a weight is placed on the north-facing end of the compass needle to somewhat compensate for this effect.
MAGNETO—A self-contained, engine-driven unit that supplies electrical current to the spark plugs; completely independent of the airplane's electrical system. Normally there are two magnetos per engine.
