                        IRS General Theory 


           The IRS provides basic Headings and Attitude reference information by utilizing computations based on  accelerometers and laser gyro sensed signals . Three accelerometers and three laser gyros are used . The accelerometers are of the strap-down type and are positioned in the inertial reference units so that they are oriented along the Y , R and P axes of the airplane . This orientation allows the IRU to sense accelerations along each of the three axes . The three laser  gyros are also of the strap-down type and are positioned to sense pitch , roll , and yaw rotation around the Y , R and P axes .

          Computer manipulation of the signals from all six sensors provide the basic heading and attitude reference signals  along with present position , accelerations , ground speed , drift angle and attitude rate information .
  The first requirement which must be met for proper IRS operation is alignment . IRS alignment basically consists of determination of local vertical and True North

        

Radar separation will be of  5 nm. On terminal areas may be of 3 nm
Speed adjusts   Expect the pilots keep up the requested speed , within more or less 10 kts
Maximum speed in aerodrome traffic to intercept the final approach is 180 kts  // 250 kts in TMA / CTR  areas but may be increased above FL 100 in accordance with Approach Control
 

Criterion for approach

Arrival time in 30 min -  APP preparation and landing planning
Briefing for landing must contain
the Atis weather information and runawy in use for approach // go around procedure  // ground operation to gate
Heavy aircrafts - Slats at mms at
20 nm / 6000 ft height  // 10 nm - approach flaps for final intercept

Precision approach  and  the specific cat ii or  iii

ILS CATEGORY I      DA "            Barometric  -  Altimeters operations

"DA" DECISION ALTITUDE - not less than 200 ft and visibility 2400 ft [800 mts] ½ nm
Localizer must work for approach

Operational restrictions - FOR CAT I
If glide slope out of service - DA shall be the MDA for NDB / VOR  to the same RWY
MM and NDB coupled  out of service - Then add 500mts to visibility, and 100 ft to ceiling,
But no changes if - VASIS or ALS [approach Landing System] in operation.
OM out of service - other facility must help to intercept the Localizer 3 to 5 nm away from OM fix.

Cat I  Procedure   For marginal meteorology operations, the co-pilot perform the A/P approach, and at 100 ft to minimum, the captain monitor outside and at DA on visual contact take over and accomplish the landing watching  the ALS - white aligned; green transverse on threshold; then  RCLL - runway center line and lights  whith  runway edge lights system; might have red transverse at the end

 

ILS CATEGORY II    DH "              Radio   -   Altimeters operations

"DH" DECISION HEIGHT - not less than 100 ft and visibility of 1200 ft [400 mts] ¼ nm

Operational restrictions - FOR CAT II  
Full ILS and all Facilities must work

Cat II Procedure  Co-pilot watch FMC information on instruments and continue till after landing
Captain perform autopilot and 100 ft to minimum monitor outside allowing the AP makes the landing! watching the  ALS - white aligned; red transverse; green  transverse on threshold; then RCLL - runway center line and lights - white aligned no matter the rwy lenght; [last 3000 ft]  2000 of whites and reds; finally last 1000 - only reds


                     RELS - runway edge lights system , same pattern RCLL

AQUAPLANE  - Happen  when the speed in NM is 9 times the square root of tire pressure. Slippery is different!      Observe, auto land  wind component limits - 25 kts lateral / 10  tail / 15 head
Speed add ½ of longitudinal component plus gust, but the add limit to Vref is 20 kts

 

Non Precision approach   "MDA" 

" MDA " MINIMUM DECISION ALTITUDE  
Barometric  -  Altimeters operations   may follow up the profile of the precision approach procedure.   But different radios facilities.  Observe distance, heights; same gradient. When flying visual on final,   turn off the F/D system.
 

Wide Bodies


Wide Body Aircrafts  -  Back track on runways without exit -To make the turning at the end of the runway safety, the projection of turn center on ground, is in the middle of the inside  wing. Therefore only the nose wheel should go along the wide area avoiding one main gear comes out
 

                                           Maximum Taxi speed 25 kts;  turning  10 kts   [wet 5 kts]

 

Pull Up decision
Pull up if at 500 ft up to 300 ft if lOC deviation > ½ dot or  G/S deviation > 1 dot threshold is the limit.
 
Do not pull up after touchdown with auto brakes observe speed brake deploy, reverses, brakes at last shut down engines if necessitate. 

Go Around  after
OM established on ILS - set G/A  HDG and G/A altitude 
Be able to apply
power pitch up of 15º lower the attitude to 12 ½ if one engine is missing - APP Flaps; Gear up; climbing till go around altitude with approach flaps till go around altitude directly even though one engine is missing. But You have to make a step climb at acceleration height for clean up for best climb performance - if above MLDW and one engine is missing - following the chart procedure.

Planning for Take Off, before start engines

Briefing must contain  Atis; Wx Rwy conditions; TO mode; Acceleration Height; Taxi from gate to the Hold point; Stand instruments departure; Noise abatement; Min safe altitude; Transition Altitude;  Consider alternate aerodrome if TO below minimum  or on ice condition or heavy weight x Short runways  V1 must lean on VMC  and 
  Procedure in case of Return  - If necessary the pilot might land on overweight - The landing distance is always less than the distance for same weight to take off  For an emergency situation focus survive being at the safe side!  
On fire do not make fuel dumping! 
    If lose one engine of the two, think as well as fire!
Obs - BW + MPL = ZFW; MLDW and MTOW  - These weights are for seeking limits in order to protect the long life of the aircraft structure, due to airlines schedule flights.

in taxi out to the Hold Point  50 mts [30 mts for rwy less than 900 mts]

Briefing must contain   Left hand TO with flaps___, I will apply initial power w/ auto throttle on . Power will be confirmed by 80 kts  Any malfunction before 80 kts, we can abort for any reason, after and up to V1 only if one engine failure, confirmed by two parameters, or acceleration interrupted, then I will call  "Abort" and carry out the action , applying maximum brakes, closing throttles, full reverses. ___ monitor spoilers deploy and reverses  After V1 w/ gear up but not less than 400 ft I will call for appropriated actions! 
If TO is performed by co-pilot as soon the plane pass through 80 kts the "abort" must be accomplish by captain!

Average TO atitude  pitch up  17 ½; if lose one engine, immediately pitch down  to 12 ½.

Take Off at or below minimum Ifr - in terms of ceiling and visibility, are the same as those prescribed for landing contained in IAL Charts for the active runway. Take off, under conditions below minimum, consider an alternate take off aerodrome. be aware if one engine is lost, aircraft must be able to accomplish the climb rate on SID, and reach the lower IFR  level  in order to proceed !
Below minimum the landind is at capt discreption

Initially after take off - stop climbing at altitude restriction, always! Do not rush!

Noise Abatement 1500 ft climb thrust; 3000 ft V/S 1000 ft flaps /Slats on schedule.


Segments

First L off -                    Gear up
Second Gear up -             400 ft  [Eng Loss ID /Procedure]
Third 400 ft -                 Flaps / Slats retract
Fourth 0o retract -              1500 ft   
 

Ice Conditions  - use of A/Ices system 

For Take Off

with present humidity 
OAT less than 10º C
Visibility less than 1 nm [50]  or  OAT minus Dew point < 2º C  
Engines  A/Ice must be ON - after engines have been started and stay ON for taxi and TO
On critical weather - when temperatures are among minus
10º  up to 0º C - on marginal runway with ice consider V1 lean on VMC for TO and - In flight Wings anti Ice should be turned  ON  after engines A/Ice is ON  then after climb power and before flaps or and Slats retracted

In flight

within present humidity - TAT minus
15º up to 10º
Continuous  IGNITERS must be ON so as to turn the engines and the wings A/Ice - ON 
In flight wings may be switched  OFF - after Flaps and Slats is retracted.  
On approach for Landing A/Ices can be leaving ON for landing - The safety SW will turn it off automatically, or in case of pull up for go around it will be properly ON 
On ground - Do not retract Flaps/Slats after land till visual check.
Wing System are used primarily as DE-ICE
Engines  A/Ice will be automatically turned  ON in case of loss Electric System in flight. The same does not occurs for wing and antenna. 

 

TRIGONOMETRY

Trigonometric approach -
Aircraft meteorology radars utilize references lines of 30º; 45º and 60º making easy to imagine the lateral distance to fly on off set route, so as to avoid heavy clouds ahead.   As a general rule of thumb, taking a distance upon a point on reference line either 30º right or left, the lateral distance for fly on off set route is 0.5  [50%]  of that distance - So you may ask ATC to fly  ...  miles on the right or left and remain well for…. nm ahead.    The same way for lines angles of 45º,   but is   [.7] 70%

Lateral wind component on final approach -
The wind direction and velocity given as a final result vector, make with the runway an angle that
one can determine two components. Quick lateral wind [velocity] component value for angles of 30º is  [.5]; more and till  45º is [.7];  more and till 60º is [.9]   / More than 60º  consider the total wind velocity value given!          Example - angles among 30º and 45º the maximum lateral component - take the 70% of the original wind velocity - suppose an original wind velocity of 20 kts  -  then the maximum lateral wind velocity component shall be around 14 kts         Video Youtub

        The atmosphere is a layer of gas which surrounds the earth. The composition of the atmosphere is relatively constant . Nitrogen  78%  Oxygen   21%  Carbon Dioxide and rare gases  1%

Nitrogen - - - - - Nitrogen makes up the larges portion of atmospheric pressure. The gas itself is useless as far as the human body is concerned. However, under conditions of low pressure this gas may cause serious physiological troubles. Most of us are familiar with the term “bends”. These are pains which occur primarily in the joints of the body and are attributed to nitrogen coming out of solution whenever the normal pressure around the body is greatly and rapidly lowered. The “bends” rarely occurs with a rapid drop in air pressure below altitudes of 25,000 to 30,000 feet and should not be a problem in airline operations.

Oxygen - - - - - This odorless gas is essential for life. When the body is deprived of oxygen, serious complications or death follows a short time later. Each time we breathe, 21% of that breath is oxygen. In the lungs this gas is absorbed into the blood and is carried to all parts of the body and is used to burn or oxidize food material for the production of heat and energy.

      Pressure Characteristics of the Atmosphere

         The layer of gas (atmosphere) surrounding the earth is affected by the earth’s gravitational pull. We are all familiar with ways we express atmospheric pressure such as 14.7 pounds psi, 29.92 inches of mercury or 760 millimeters of mercury.

         Because the absorption of oxygen in the blood is dependent upon the differential pressure inside the lungs and atmospheric pressure, it is important to remember the density ratio of atmospheric pressure at various altitudes.

At sea level when we take a breath, air fills the lungs because of the lowered pressure inside the lungs created by the lowering of the diaphragm and expanding of the rib cage. The volume inside the lungs is increased and the pressure then decreases. Atmospheric pressure now being greater causes air to flow through the mouth or nose and into the lungs creating a partial pressure of oxygen of about 103 mm of Hg. This is sufficient to cause the O2 to move across the very thin lung membranes and over into the blood where it combines with hemoglobin in the red blood cells. As the blood circulates throughout the body, oxygen is supplied to all the cells.

If one ascends to a pressure altitude of 18,000 feet, ambient air pressure is only ½ that at sea level. The partial pressure of oxygen in the lungs is about ½ normal and the person will suffer from lack of oxygen. This deficiency of oxygen to the body cells is known as hypoxia. Since the brain cells are first affected, followed very closely by the eyes, one’s ability to perform normally deteriorates rapidly. Some of the more common signs and symptoms of hypoxia in a normal person at different altitudes and the percent of arterial blood oxygen saturation are shown in the following table:

At higher pressure altitudes the time of useful consciousness (T.U.C.) is quite brief. T.U.C. may be defined as that time that one can do something for himself, such as properly fitting his oxygen mask, turning on oxygen regulators, etc.

The following table shows T.U.C. at various altitudes. These times were arrived at by studying thousands of cases of military personnel in altitude chambers. They show average T.U.C. at each altitude when the O2 mask was removed, under conditions of rest, moderate activity, and rapid decompression.

        These are average T.U.C.´s. One’s tolerance to hypoxia varies considerably from time to time. Intake into the lungs of carbon monoxide from excessive smoking, or other sources, greatly reduces available oxygen to the body tissue. Alcohol in the system, even though consumed as long as 18 hours previously poisons the body cells and interferes with the utilization of oxygen. Fatigue lowers one’s tolerance. The athletic, physically fit individual has a markedly higher altitude tolerance that the overweight person. O2 consumption of the overweight no athletic person is also greater during periods of stress.

    MOMENTOS  O princípio da alavanca estabelece que uma pequena força, aplicada a uma grande distância do ponto de apoio, levantará um grande peso,  cujo centro de massa esteja a pequena distância desse ponto de apoio. Quando uma barra sólida é equilibrada sobre o bordo de uma faca e nas suas extremidades penduram-se pesos, observa-se que um peso de 12 quilogramas, suspenso a um metro à direita do ponto de apoio, equilibra-se com um peso de 6 quilogramas, suspenso a dois metros à esquerda do ponto de apoio, ou por um peso de 4 quilogramas suspenso a três metros à esquerda do ponto de apoio. Chama-se momento de uma força em relação a um ponto ao produto da intensidade da força pela distância desse ponto à direção da força, distância esta que é medida pela perpendicular baixada do ponto sobre a direção da força. Diz-se que o momento é positivo quando a ação da força tende a produzir um movimento em torno do ponto, no sentido do movimento dos ponteiros do relógio. O momento é dito negativo no caso contrário.  Para que haja equilíbrio, é necessário que a soma algébrica de todos os momentos que atuam sobre um mesmo ponto seja igual a zero. Voltemos ao exemplo anterior, no qual 12 quilogramas foram pendurados a um metro à direita do ponto de apoio. Uma vez que o peso atua para baixo e à direita do suporte, ele tende a produzir um movimento no sentido da rotação dos ponteiros do relógio. Por isto, o momento é positivo, levando o sinal +. A distância da força ao ponto de apoio, em torno do qual se produz o momento, chama-se braço do momento ou de alavanca que, no caso presente, é de um metro. O momento da força em relação ao ponto de apoio é + 12 metros quilogramas. Este momento será equilibrado por um momento de – 12 metros quilogramas.  Este momento negativo pode ser produzido, seja por uma força de 3 quilogramas atuando para cima, 4 metros à direita do ponto de apoio, ou por uma força de 4 quilogramas atuando para baixo, 3 metros à esquerda do ponto de apoio ou, ainda, por uma força de 1 quilograma atuando horizontalmente para a esquerda e 12  metros para cima do ponto de apoio; ou, ainda, outra qualquer combinação de força e braço de momento que produza 12 metros quilogramas e que tenda a imprimir uma rotação no sentido inverso ao do movimento dos ponteiros do relógio.
    VETORES  Chama-se vetor toda grandeza que tem intensidade e direção.   Quando se representa uma força, deve-se indicar a intensidade e a direção na qual está atuando. A força é, por isto, uma grandeza vetorial.   A velocidade é a distância percorrida na unidade de tempo;  todavia, freqüentemente esquece-se de considerá-la um vetor.   Ela só é considerada vetor quando se refere a uma direção dada. Todas as vezes que se usa a palavra “velocidade”, ela especifica não só a grandeza do movimento em dado tempo, como também a direção na qual está se dando este movimento.
    COMPOSIÇÃO DE FORÇAS   Quando duas forças estão atuando exatamente na mesma direção, isto é, quando suas linhas de ação coincidem, podem ser somadas ou subtraídas diretamente. Qualquer ação produzida por estas duas forças, atuando ao mesmo tempo sobre um corpo, é equivalente à ação de uma só força, cuja intensidade é igual à soma algébrica das intensidades das duas forças. Esta força única chama-se resultante das outras duas. As duas forças chamam-se componentes.  Quando duas forças, de intensidade e direção iguais, atuam em sentidos opostos sobre um corpo, a resultante é nula.  Quando duas forças atuam sobre um ponto mas, as suas linhas de ação não coincidem, procede-se da seguinte maneira;  - constrói-se  um gráfico no qual cada força é representada por uma reta que indica não só o sentido em que a força atua, como também a sua intensidade, em uma escala previamente estabelecida. Na extremidade da reta, coloca-se sempre uma ponta de seta para indicar o sentido em que a força atua. Constroem-se sempre o diagrama de modo que as força se afastem do ponto de encontro.  Da extremidade oposta de cada reta que representa uma força, traça-se uma reta paralela à outra força, formando-se assim um paralelogramo. Traça-se   a diagonal que, partindo do ponto de aplicação vai ao vértice oposto. Esta diagonal representa a  força resultante. A força resultante, ou simplesmente a resultante, é uma só força que produz exatamente, o mesmo efeito das duas forças originais, atuando sobre o ponto de aplicação. A intensidade da resultante é obtida usando-se a mesma escala que se adotou para as duas forças originais ou componentes; e a sua direção é obtida aplicando-se um transferidor sobre o diagrama .
