Ma non fare lo scorbutico Maresciallen!
Ecco l'estratto riguardo all'SM.79, ve lo leggete mentre scaricate il pdf, il bombardamento si fa a mano (e a parte il bombsight piu' "artigianale" la procedura e' la stessa a cui siamo abituati con l'FW200), ma c'e' un aiuto per l'angolo di deflessione delle torpedo:
Pilot's notes
Propeller pitch has only two effective position in SM.79: minimum (fine => higher RPM), used for takeoff and climb,
and maximum (coarse => lower RPM) used for level flight and other conditions. In IL-2, this is modelled so that
“prop pitch” positions from 100% to 50% corresponds to fine, “prop pitch” positions from 49% to 0% correspond to
“coarse”. The pilot should switch to “coarse” after climb (by reducing “prop pitch” command below 50%) to
avoid over-revving and ruining his engines. Prop control: maximum allowed RPM is 2400/min.
Flaps: SM.79 has completely automated flaps/slats. These are automatically and gradually deployed (via hydraulic
actuators) when the aircraft IAS falls below 210km/h. Maximum extension is reached when IAS drops to 140km/h.
Retraction is also automated, at the same speeds. Ailerons also act as flaps (flaperons) by deflection downwards
with the automated mechanism
Bombsight
The Jozza bombsight is an open sight view (without scope or other optical sights) with manual bomb drop.
In the real word, usage of this sight was rather complex; three different methods for range sighting existed. The first
two ones implied the use of ballistic tables for each type of bomb, and of indexed scales that are on the instrument
(that cannot be implemented in IL-2). The third sighting method only implies measurement of TAS and height, so
can be adopted in IL-2.
Torpedo sight
The “Marazio-Unia” Torpedo Sight is mounted when a torpedo is chosen as arming option. In this case, the
bombsight is not present. This torpedo sight is a very simple graphometer, it indicates the lead angle that must be
calculated/estimated via some external way (torpedo tables or Bruno's excellent torpedo tool, (see
http://brudile.googlepages.com/torpedosight.zip). The angle is changed using the bombsight side-slip keys and can
be a visual help for manually dropping the torpedo.
Torpedo
The Whitehead torpedo can be launched at a slightly higher height than other torpedoes (slightly above
100m) but it sinks in the water more than others before getting to the correct depth. For this reason, it must
be dropped at no less than 400-500m from the ship; otherwise it will pass below the ship and will not
explode.
