Lancaster Air Position
Indicator
(pg1 instruments)
Here we have
an Air Position Indicator as used by the Navigators of
Lancaster Bombers
Mk 1.B
Reference 6B/458
The Air
Position Indicator (API), is an electromechanical device
that combined the
input from the Air Mileage unit, which gave the true
airspeed, and the heading being flown from the
Distant Reading Compass (DRC – a gyro-magnetic compass that
also had a manually input correction for magnetic variation)
to displayed the air position (i.e. the position of the
aircraft assuming no wind),
displayed as a latitude and longitude, based on a starting
position set at the beginning of the flight

A/M 10Q/37
GEE was a navigation system for aircraft that was
evolved by British scientists to meet the needs of the Royal
Air Force during World War II, at a time when both Bomber
and Coastal Commands faced serious navigational problems.
The system subsequently remained
in service until 1970.
Seen in situ in a Lancaster
bomber
Accurate navigation by day and night under conditions of
radio and radar silence in indifferent weather, by unlimited
numbers of aircraft flying under conditions where tactical
considerations prevented straight and level flying, called
for a position fixing aid which could be operated quickly
and simply.
GEE became operational about the time that the thousand
bomber raids commenced in 1942, and when the battle of the
Bay of Biscay was reaching its maximum.
It was the first
serious attempt to provide the navigator with a rapid means
of determination of position, and seldom has any one
invention so faithfully and quickly satisfied the
requirements for which it was developed.
The principle of operation was the measurement of the time
difference between the reception of pulses from ground
transmitters (working in pairs), measured on a cathode ray
tube display in the aircraft. Two or more Slave ground
stations, working with a common Master station, constituted
a complete Gee Chain.
The time difference between signals from two pairs
of stations were measured simultaneously.
When the readings were referred to pre computed lines on
a special chart, the two simultaneous position lines
obtained combined to give a position fix for the navigator.
To secure a position line, an aircraft had to be within
range of two transmitters, and to secure a position fix,
within range of three stations, ie., a common Master and two
Slaves.
