CloD - Fiat BR.20 Cicogna "Flying Manual"

Post by 21_Sokol1 »

Condor, procedimentos básicos para o Fiat BR.20, by = UAI = Shkrab (Ex-piloto de Mig-21) - TT & Notes Sokol1

O Br.20 é talvez o avião mais exigente do CloD e completar uma missão com ele é muito gratificante.
Br.20 the "Cicogna"

BASIC SETTINGS

FUEL - Use 30%, this make plane more maneuverable and provide 2 hour of flight - if the enemy don't puncture your tanks. (NT - And after all, you will not fly back to Rome ;) ).

BOMB LOADING - 12 General Purpose (another types don't show advantages), selec bomb weight (50, 100, 250, 400, 800kg) accord your target.

TURRET SETTINGS - Put red ammo tracer in all turrets (it's help aim if you jump to gunner position, and the most important is the negative effect on human piloted fighters, who tend to move away from the tracers, dodging his attacks). Set convergence in 500 meters.

NT - In il-2:CloD Br.20 rear turret is not designed for control with mouse, but with joystick X and Y axis, but to avoid move turret and plane controls at same time use a modifier key/button (*ie. space bar ) in turret axis configuration together with axis, so pressing this key/button an moving joystick only the turret move, to shoot set joystick trigger. This result in probable the best turret control see in any WWII sim. But this is valid only for BR.20 rear turret. For another turrets (and planes) use mouse (is advisable to increase the sensitivity to 1.5 or more in conf.ini.)
And remember that in il-2:CloD turrets only fire is plane vertical movement is lower than 5 m/s (UbiZ00 wishes).

PRE-FLIGHT SETTINGS

- Set both throttles in 8%
- Cowl flaps and oil radiator in 0%
- Mixture in 100%
- Carburetor heater in 0%
- Propeller pitch in 75% - don't change this settings throughout the flight.
- Select left engine and start
- Select right engine and start
- Select all engines
- Adjust altimeter to "0 m"
- Switch the cylinder head sensor to right or left with "Telepirometrico eletrico" switch on panel.
- Turn on the main and secondary cockpit illumination (that make easy look at instruments even even in daytime flights) .
- Elevator trim - one notch upper (optional during taxi)
- Monitoring engines temperature.
- When engines temperature reached 30 degrees, throttle up smoothly (very slowly) to 15-30% (to quickly engines warm) .
- When engines temperature reached 50 degrees - you are ready to taxi .
- Open cowl flaps to 30%
- Open oil radiator to 25-30% - don't change this settings throughout the flight.
- Due lack of frontal visibility for pilot (especially at night) you can ease taxi if change for bombardier cockpit and look front through bombsight (Shif+F1) adjusted to 370KMH - this provide a good frontal view.
- With engine temperature around 50 degrees ... you can safely increase the engine revs to 100% to aid steer.

TAKEOFF

- Engine temperatures should be no less than 150 degrees (cowl flaps opened by 25-30% )
- Oil temperature should be no less than 50-70 degrees (oily radiators open to 25-30%, switch indicator arrow at 9 o'clock).
- Mixture in 100%
- Carburetor heater in 0%
- Elevator trim up one notch. The plane have tendency to nose dive after rise Landing Gear.

NOTE - For faster takeoff you can use Boost ("Fast and Furious" accord Google translator ) (engines revs in 110%)

-Set flaps in the takeoff position, the second mark on the indicator (NT- right side of cockpit, behind co-pilot - use "hold to offset camera" key to better view) pressing "Lower Landing Flap Position" key (default V) to 8-10 seconds.
- At speed of 150 KM/H the plane smoothly detached itself from the runway. Make sure that immediately after takeoff raised flaps fully a retract the landing gear.

CLIMB

- Engines temperature should be around 190 - 220 degrees (adjust cowl flaps, usually after takeoff set to 40% open is OK)
- Oil temperature should be 50 - 60 degrees (at all altitudes and flight whit fly flaps pol radiator set in 15% open is OK).
- Reduce mixture 10% at each 1000m of additional altitude:

90% at 1000m
80% at 2000m
70% at 3000m
60% at 4000m
50% at 5000m
40% > 6000m

- Carburetor heater - temperature drops with altitude, but should be maintained at 15-20 degrees. Sometimes in flight you have to switch engine left or right to align the temperature of carburetors. Sometimes ... to maintain carburetors temperature at 15 - 20 degrees, engines revs need to be set a 15% on left and 35% on right. At medium altitudes (up to 3000m) engines temperature control parameters is not affected .. but with the rise to a height above 3000m keeping temperature between 15-20 degrees avoid overheat . 230 degrees is the maximum admissible at height of 7.000m.
- Propeller pitch a 75% (in all flight modes don't need to change).
- WEP (110% of engine revs)- In normal flight it's not need. If used monitor engines temperature.

NOTE

1. Engine temperature instrument. Under FOV 70 (End key) the instruments in cockpit are highly readable. Always after takeoff mouse over temperature instrument - the indicator needle of instrument don't move, but always have seen slightest temperature changes in the digital information.
2. If in flight you move to crew positions , make sure, especially being on upper turret, to return to pilot position via navigator position (or use Alt + F2 - don't use C (change positions) this is command is bugged) to make room for AI gunner. Otherwise, they don't detect and don't react to enemy attacks. And after the flight the pilot will run around the aircraft with a revolver in hands to shoot your gunners for treason.

DIVING BOMBING

Level bombing is not considered ... that's a peculiar subject when looking through bombsight scope. Without Autopilot keep plane aligned with target is unrealistic hard. Visibility, even at height of 2700m is very bad ... Only target area is viable to horizontal bombing. Use Br.20M as dive bomber.

NOTA - Para Bombardeiro Nivelado e Autopilot veja nova postagem abaixo.

Before attack.

1. Open bombay doors (watch the crank in bombardier cockpit or hold the key/button for at least 6 seconds to open/close teh bombabay doors).
2. Arming bombs
3. Select short delay
4. Select salvo mode single

Dive Bombing Attack

You dive fron any height, even 5.000 -7000 meters. The aircraft is subject to flutter, ie... destruction of planes controls. Dont exceed the speed of 500KMH. Dont overload +4, -2 G.

Before entering into a dive.

Adjusts:

- Propeller Pitch in 0%.
- Oily radiator in 25-30% open.
- Cowl flaps - depending on the actual engines temperature, adjust if need.
- Mixture - Don't change settings.
- Carburetor heater - Don't change settings.
-If the height of input into a dive > 1.000-2.000m reduce throttle to 0%.
- If the height of input into a dive > 3.000-6.000m lower the Landing Gear, to not exceed the speed of 500KM/H. Remember when exiting of dive rise the Landing Gear.

Diving:

- Reduce throttle to 0% .
- Reduce Propeller Pitch to 0%.
- Start the dive.
- Lower the Landing Gear.
- After entering into a dive align with target.
- Center trim.
- Drop the bombs. IF you did all correctly, dont overload +4G. Recover.
- Raise Landing Gear.
- Propeller Pitch 75%.
- Increase the mixture to 100%
- Carburetor Heater 0%.
- Engage WEP (engine revs 110%.)
- Climb to 500m-1000m of height, and "get out!"

The advantages of these methods are...

1. At recovery of dive (at any height), the engines temperature normally are 140-150 degrees. Then increase to 190-200 degrees.
2. High speed at end of dive - 400-500KM/H (but this is not critical).
3. High speed at recovery and engines performance provide greater maneuverability in the climb.
Os motores do BR.20 tem uma tendência a "pipocarem", o que é causado pela baixa temperatura do ar admitido nos carburadores, use o "Carburetor Heater" para compensar.

"AUTOPILOT"

No centro do para-brisas do BR.20 a um instrumento com escala horizontal dividido em três faixas:

Superior = Compass (bússola)
Central = Slave Compass
Inferior = Course Setter

O Slave Compass é uma bússola estabilizada por giroscópico, que para girar precisa de ar comprimido, fornecido por um “Avio Compressori Garelli RE” instalado embaixo do banco do co-piloto.

Para ligar/desligar este compressor use as teclas “Start/Stop Motor Compressor” (é preciso designar).
Não haverá informação ON/OFF no “HUD”, mas notará que o avião começa a chacoalhar (bem) perceptivelmente...

A vantagem do “Slave Compass” é que devido a estabilização giroscópica não vai desestabilizar tanto durante as curvas como acontece com a Bússola (“Compass”) e o “Directional Gyro”.

Se optar em não usar o “Slave Compass”, corrija constantemente o “Directional Gyro” com a leitura da Bússula (“Compass”).

Os demais procedimento para engajar o “Autopilot” são:

Alinhe o DG com a Bússola (“Compass”).

Defina o rumo no “Course Setter” – faixa de baixo do instrumento triplo instalado no meio do para-brisas.

Como o “Autopilot Course Preseter” não tem mostrador (como nos aviões alemães) e é pré-ajustado no HDG 60, ou alinhe a aeronave nesta direção (60) para então engajar o “Autopilot Course/Mode 22” e depois corrija para o rumo pretendido, ou tente primeiramente ajustar as cegas o “Autopilot Couse Preseter” para o rumo pretendido usando a “RotT”: tecla pressionada ~2 segundos ajusta 10 graus...

By ATAG_Torric270
Key bindings needed: course autopilot next mode; course autopilot adjust course left and adjust course right; directional gyro increase and decrease; [(BR.20) start motor compressor; stop motor compressor]

Simple mode: After takeoff, trim your plane on desired course for your climb. Hit autopilot next mode, you will get a read out that says mode: course. Your plane will start to turn, just hit your adjust course left/right keys until the plane is flying on the course you want. The AP default course is N so the farther away from N that you are the more turning that will initially be needed. This is mode 1 (course) you can climb, dive, fly level using elevator trim as it only controls the rudder. BR.20; for a more precise AP, start motor compressor to spool up the directional gyro (will shake the plane); known bug.

For mode 22 (level flight, level bombing) hit the autopilot next key and it will say mode 22 (). Now the autopilot will control rudder, elevator, and ailerons. The plane will most likely dive for a bit to help it level out so pick an altitude at least 300-500 meters above what altitude you want. The Blennie's nose will bounce up and down (known bug)

For both of these modes just use your course autopilot left/right keys to turn the plane. You can also use the directional gyro keys for smaller movements.

BR.20: Without the motor compressor on, the plane will drift more than other planes so it will need constant adustment.

For total correct navigation: BR.20: During startup turn on the motor compressor. Both: Turn the dirctional gyro to match the magnetic compass (You will have to continually match the gyro to the compass during flight)

Take off and pick your course, match gyro to magnetic compass, then hit autopilot next mode, then repeat the above steps.
GERENCIAMENTO DE BOMBAS E BOMBARDEIRO NIVELADO

O Bombsight do BR.20 é calibrado no sistema métrico, o que requer a conversão da IAS para TAS, para isso use o STEAM Browser e as ferramentas disponíveis na “ClodTools”, ou o seu método preferido.

O BR.20 requer armar as bombas, abrir o “bombay” e configurar salvo/series e delay (as teclas no lado direito do cockpit do bombardeador são animadas, mostrando as opções selecionadas).

Devida limitação da visibilidade à distância (pop-up de objetos) e ausência de auxílio ótico no bombsight a máxima altitude prática para bombardeiro nivelado é 4.500 metros.

O “bombsight” do BR.20 é similar ao do Blenheim, sem auxílio ótico, use o “circulo e conta” para a visada.

O lançamento das bombas é manual.

NOTA – O ponto visado é onde cairá a última bomba de uma salvo/série, portando mire um pouco antes levando em conta a distância ajustada no delay.

O top gunner - controlado com o joystick - fica bem preciso (desde que o gunner não "entre em pânico"), aliás fica o melhor controle de "turret" que já ví num simulador deste o 1942 - Pacific Air War, de negativo a baixa cadência da Breda 12.7 "mike mike".

E tem que ter dedo leve, a munição não é muita e não tem recarga, já que é por fita.

E, já que pretende "salvar a pátria" assim que subir deixe a torreta na posição elevada, pois o tempo que ela gasta para subir permite ao gunner descer na cabine de rádio e tomar um pouco de "coragem".

Os outros dois (front, waist) servem basicamente de "apoio moral" (para a tripulação), não tem muita utilidade devido ao restrito movimento das (fracas) metralhadoras 7.7 "mike mike", também alimentadas por fita.
