Pilot's Notes - original EVS SV-4B manual and system details.



In the early years pilots had no internal radio system but had to speak in a "horn" as seen on this picture

This is the vintage navigation light that was fixed in the middle upon the upper wing. This kind of navigation light (not allowed anymore) was green at the starboard side, red at the port side and white in the back (so 3 colors in 1 light). The same navigation light was fixed in the middle of underneath the lower wing


In the back cocpit of the SV-4B a morse key was installed to manipulate the identification (morse) light. There is at this moment only one SV-4B still flying with this kind of identification light, the V29 OO-GWB. The lamp was fixed at the right side under the fuselage, some 40 cm after the lower wing. The morse key could be set locked and unlocked, and was used in case of radio problems.
