Mathematic Review….. Some triangles do not always have a 90º angle, therefore the normal trig functions do not always apply. The following formula is used to solve the RNAV questions. The SIN Rule : a SIN A b SIN B c SIN C = = The COSINE Rule : a² = b² + c² - 2bc x COS A b² = a² + c² - 2ac x COS B c² = a² + b² - 2ab x COS C Trigonometry
The Right Angled Triangle Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angleratios
SIN B = At 1205, aircraft A and B are 75 nm's apart and are on a collision course. Aircraft A 330 Kts. Aircraft B 360 Kts. The relative bearing from A to B is 075. What angle needs to be closed by aircraft B to intercept aircraft A? SIN B = B = 62.3º Example:
An Equation is like a balance scale. Everything must be equal on both sides =
Cross Multiplication Moving the variable around in a function, until the unknown variable is isolated. Example: In a² = b² + c², if we have to solve for c we have to isolate it on one side of the equal sign. Important: What you do on one side of the equation has to be done on the other side. Thus: a² = b² + c² - b² leaves c² isolated, but then we have to subtract b² on the left side of the equation as well: a² - b² = c²
Percents Have Equivalents in Decimals and Fractions 20% = == DecimalFraction Simplified Percent
Included % When asked to work out the % of reserve fuel when it’s already included in the total given, care must be taken with the mathematics: Example: We have Lt of fuel which include 15% reserve – how much fuel do we have available without using the reserve fuel? If we started with Lt and then had to add 15% reserve it means: x 15% = = Lt total fuel. To reverse the calculation (how much fuel do we have without the 15%), we have to divide the total with Or ÷ 1.15 = Lt
Interpolation: 1. to insert between or among others 2. to change by putting in new material 3. to estimate a missing value by taking an average of known values at neighboring points
Interpolate one series at a time: PALT AUW LBS – 1237 = 31/2000 X 1500 = 2,25 (+1237) = AUW LBS – 1098 = 22/2000 X 1500 = 16,5 (+1098) = AUW LBS 1260 – 1115 = 124/2000 X 750 = 54,37 (+1115) =

Cardio-respiratory System -The Lungs and the transport of Oxygen Air enters through the nose and mouth and passes down the trachea to the bronchial tree. Human Performance…
When you inhale, air is drawn into the lungs due to a reduction in pressure inside the chest. This reduction in pressure can be ascribed to the outward movement of the chest wall and the downward movement of the diaphragm. When exhaling the air is expelled from the lungs by the generally passive process of muscular relaxation allowing the chest wall to fall and the diaphragm to relax. The ever dividing passageways in your lungs terminate at the alveoli (very fine sac-like structures) where the blood in the alveolar capillaries is brought into very close proximity with oxygen molecules. Under the influence of a pressure gradient, oxygen diffuses across the capillary membrane from the alveolar sac into the blood. From there it is taken up by the protein molecule hemoglobin for transport around the body. Breathing provides an exchange of respiratory gases between the environment and the blood. The rate and depth of breathing are adjusted to meet the enormous changes in the consumption of oxygen and the elimination of carbon dioxide.

When the South Easterly winds are forced to rise up over Table Mountain, the famous "table cloth" cloud forms – The descending air on the other side of the mountain is warmed, and any moisture present is absorbed by the air as water vapour. Both sides of the mountain will be clear of cloud, while the summit is cloud covered. CLOUD INDICATING WIND LOCAL WINDS Caused by steep pressure gradients when the anti-cyclone flow of air from a high pressure system to the south west of the country The sudden dramatic change of this south westerly wind, which replaces the prevailing north easter is a common feature of the Buster. During the summer months there is frequently a strong south easterly wind prevalent over the Cape Peninsula.
Cloud Classification Stratus (St). Layered clouds that form in stable air near the surface due to cooling from below Cumulus (Cu). Cumulus clouds form when convective currents from the earths radiation exist. They usually have flat bottoms, and dome shaped tops

The ADF Relative bearing information can be displayed on either a RMI (radio magnetic indicator) or on the older RBI (relative bearing indicator). The difference between the two indicators is that the RBI does not display compass heading information but remains on a constant heading as selected by the pilot. Signal Characteristics NDB's transmit vertically polarised signals in the medium freqency (MF) band. The signal is radiated equally in all directions and aircraft equipped with receiving equipment (ADF) can measure the direction of the incoming waves. RBIRMI

Surface Wave Sky wave 1 st Sky Return Dead Space Skip Distance The area between the limit of the surface wave and the point of reception of the first sky wave, is termed dead space The distance between the transmitter and the point on the surface where the first sky wave return arrives is called the skip distance
Carrier Wave (A) Audio Wave (B) Where the audio wave is positive the amplitude is increased. Where the audio wave is negative the amplitude is decreased. Resultant Wave Amplitude of A X 100 Amplitude of B Amplitude Modulation (AM). Amplitude modulation may be used to transmit coded messages at audio frequencies (AF) or to transmit speech and music. The audio signal gets impressed on the radio frequency by changing the amplitude of the Carrier wave (CW). This change in amplitude is carried out by morphing the carrier wave to the audio signal. During this process the frequency remains constant. This is a measure of the modulation depth, which is a percentage measurement of the degree to which the wave is modulated. It is the ratio:

Pressure Altimeter Construction Static pressure is measured at the Static port. As the aircraft climbs the Static pressure decreases and the capsule expands. This expansion shows an increase in altitude. As the aircraft descends the Static pressure increases and the capsule will contract. This contraction shows a decrease in altitude. The Baro correction is used to compensate for any deviation in ISA conditions. Static Vent Capsule Static Port Sealed Case Altimeter Scale Linkages Baro Correction Pointer
Detect the Magnetic Field and convert to electrical current. Electrical current interpreted by instrumentation, and represents a magnetic heading. In order to overcome the problems associated with the placing of the compass on the aircraft, the magnets could be placed outside of the cockpit, in an area where they where least affected. The problem now however would be how the pilot would see the instrument. One solution would be to convert the magnetic field (flux), into electric energy which could be interpreted by cockpit instrumentation as heading references. This is the role of the fluxvalve. Fluxvalve Theory If instead of using a magnet, a highly permeable soft metal bar is fixed to an aircraft from fore to aft, and the aircraft is placed within the earths magnetic field, the bar will itself will acquire flux (become magnetized). The degree to which this flux will develop depends upon two factors: 1.The latitude of the aircraft 2.The position of the bar in relation to the meridians of the magnetic field "Whenever there is a change of flux linked with a circuit, an Electromagnetic Field is induced in the circuit."
A B B Horizon Bar D ATTITUDE : Climb and Left Bank Attitude Indicator The aircraft's attitude relative to the natural horizon is shown by the aircraft symbol (A) and flight command bars (B). The horizon bar is carried on a flexible tape with the upper and lower sections coloured to represent the sky and ground. It also has to indicate the pitch angles. The roll angle is displayed by a pointer (D) that rotates with the flexible tape and is referenced against a fixed scale. (Freedom of movement for the flexible tape is: Pitch ± 90° and Roll 360°) Pitch and Bank Commands When armed the Pitch and Bank Commands provide the pilot with “Fly to commands”.

The Procedure Turn Approach (45 /180 )
Turn to the left Aircraft turns onto outbound heading Sector 1 – Parallel Entry The sector 1 (parallel) entry, is carried out as follows: On arrival overhead the beacon, the aircraft is turned onto the outbound heading (to fly parallel to the inbound track), for the necessary period of time. The aircraft is turned to the left, into the holding side of the pattern, to intercept the inbound track or fly directly to the beacon (as shown). On arrival overhead the beacon a second time, the aircraft is turned to the right to follow the holding pattern.

LEMAC or % MAC Introduction: Another way of expressing the position of the CG is as a percentage Mean Aerodynamic Chord or % MAC. The chord line is the straight line joining the leading edge and the trailing edge of an aerofoil. On a tapered wing the average length of the chord is calculated and termed the Mean Aerodynamic Chord or MAC. When working with MAC use a drawing to solve any questions that can be asked. MAC ( D ) LEMAC ( C ) CG (A ) DIFF ( B ) DATUM MAC
LEMAC Example No 1. An aircraft has a MAC of 162 inches. The LEMAC is at FS 324. The CG is 412 inches aft of the datum. What is the CG expressed as a percentage MAC? MAC is 162 inches LEMAC is 324 inches CG is 412 inches DIFF 88 inches DATUM

The equator is an imaginary circle equidistant from the poles of the earth. Circles parallel to the equator (lines running east and west) are parallels of latitude. They are used to measure degrees of latitude north or south of the equator. The angular distance from the equator to the pole is one-fourth of a circle, or 90°. Thus latitude would run from 90° North to 90° South of the equator. Meridians of longitude are drawn from the North Pole to the South Pole and are at right angles to the equator. The "Prime Meridian" which passes through Greenwich, England, is used as the zero line from which measurements are made in degrees east and west to 180°. Any specific geographical point can thus be located by reference to its longitude and latitude.
Convergency = Dlong x sin Mid Lat Conversion Angle = Convergency 2 Convergency = 2 x the Conversion Angle

Attitude Life and flying has one important factor in common – attitude determines altitude!! Attitude is more important than education, money, failures and successes, appearances, giftedness and skill. Bottom line – if you say you can you are right. If you say you can not you are also right.
What is Attitude? Attitude is the way we communicate our thinking to other people. Our attitude is reflected in the way we talk, walk, sit, eat, sleep, drive a car – and indeed in flying an aircraft.
Know this… Our attitude is the strongest element of our lives that requires our control Our attitude affects others Attitudes can be changed
Make The Call !! After you send a resume or an introductory letter, always make a follow-up call. Remember, it's the conversation that gets you the interview. Here's how to get on the phone and into the interview process. Never call human resources or an in-house recruiter. These people have no vested interest in talking with you. In fact, they don't want to talk to you. You'll only foul up their process. If you want to get hired, you need to talk with an actual hiring manager. If that's a midlevel project supervisor or the Operations Director, so be it.
Your attitude will make or break you as a student!
