Advanced Photography Course

Data Computer (Type BM-38A). can assist you with
many of the calculations required for mission planning.
The aerial photographic data computer contains scales,
indices, and information pertaining to frame and
panoramic camera photography as well as radar and
infrared detection mapping. This computer is a useful

tool in mission planning. It can provide quick responses
to a number of mission requirements (fig. 4-16).

The aerial computer is designed primarily for

large-format automated camera systems. However, it is
helpful in making calculations for hand-held aerial
photography when 70mm film is involved (using the

Bronica ETRS or Agiflite, for example). Information

that can be provided by the aerial calculator is as

follows:

Scale index

Scale factor

Focal length required

Ground coverage

Altitude
