Ju88 A-1: Illumination of Kraftstoff panel lights
/1/ Here is how the panel works:
"V" "Vollwarnung" "full" red oil: it is always on when the engine is running and when the oil tank > = 0 or 5 l
"V" "Vollwarnung" "full" yellow fuel: it comes on when fuel is transferred, but ... it turns on when at least one of the transfer switches (1 to 8) is engaged
"L" "Leerwarnung" "empty" red fuel: it comes on when an inner tank drops to about 110 ~ 120 liter
/2/ This is not logical:
This is an alarm panel, normally all lights should be off.
if a light comes on: it requires action
Condition of lighting of the indicator light "Vollwarnung" red oil:
I think it is used during the long, they install an additional oil tank of 106 liters at the end of the left wing.
During the flight, the engines consume oil (I did not find the average fuel consumption, someone knows it?), And a crew member must operate a manual pump to transfer oil from the fuel tank. 106 liters to the engine oil tanks.
The "V" red oil warning light should come on to indicate that the engine tank is full (> 105 liters) and stopped pumping, otherwise the oil will go into unplanned piping.
The oil consumption of the engine must lower the level and turn off the "V" red oil.
Condition of ignition of "V" "Vollwarnung" "full" yellow fuel:
It should light up only when the "inner tank" is full: 380 liter
This tells the pilot to stop transferring the fuel, otherwise the tank "overflows" and the fuel from outside.
So this yellow fuel "V" is not a pump transfer indicator or indicator on but only a high level indicator of a single tank:
The left yellow fuel "V" will illuminate if the left "inner tank" is equal to or greater than 380 liters.
The yellow "V" fuel right, turns on if the right "inner tank" is equal to or greater than 380 liters.
Condition of ignition "L" "Leerwarnung" "empty" red fuel:
It should light up only when the "inner tank" is almost empty: 100 liter
It is a unique, low-level indicator linked to a single tank:
"L" "Leerwarnung" red fuel left illuminates if the left "inner tank" is less than or equal to 100 liter
"L" "Leerwarnung" red fuel right turns on if the right "inner tank" is less than or equal to 100 liter
/3/ To simplify or synthesize, here are the logical conditions of ignition:
"V" "Vollwarnung" "full" red oil:
If oil consumption is taken into account by the game:
"V" "Voll" "full" red oil left: lit if oil tank left > = 105 liter
"V" "Voll" "full" red oil Right: lit if oil tank right > = 105 liter
If oil consumption is unknown in the game:
"V" "Vollwarnung" "full" red oil Left: off
"V" "Vollwarnung" "full" red oil Right: off
"V" "Vollwarnung" "full" yellow fuel
"V" "Vollwarnung" "full" yellow fuel Left: lit if "inner tank" left > = 380 liter
"V" "Vollwarnung" "full" yellow fuel Right: lit if "inner tank" right > = 380 liter
"L" "Leerwarnung" "empty" red fuel
"L" "Leerwarnung" "empty" red fuel Left: it lights up when "inner tank" left < = 100 liter
"L" "Leerwarnung" "empty" red fuel Right: it lights up when "inner tank" right < = 100 liter
Disable these bad ignition logic:
Fuel switch # 3 on the panel (# 5 in game): no ignition of warning light
Fuel switch # 5 on the panel (# 6 in game): no ignition of warning light
Fuel switch # 6 on the panel (# 7 in game): no ignition of warning light
Fuel switch # 8 on the panel (# 8 in game): no ignition of warning light

The fuel level measurement (see wiring diagrams in the main section
92 "Equipment - Elt-Anlage") is carried out electrically by
Donors, of which in each container (except the thrown
Wing outer container and the rear fuselage container) of an inserted

The measurement is based on the fact that with the liquid level

operated an electric remote transformer, on which the cross-coil
display device can be connected at any distance.

An examination of the level indicator for accuracy can thereby
