MAIN FUNCTIONAL PROCESSES AND SUB-PROCESSES 
(production unit) 
APPENDIX II 
1. PLANNING (project). 
1.1 Mission Planning actions and decisions include: 
- aircraft policy : own aircraft/hire in 
- crewing policy : 2 man/3 man crews 
- obtain permissions for aircraft/equipment/crew 
- collect information on Avgas, Avtur and support services situation 
- collect information on security regulations, security situation 
- collect information on geographical and meteorological characteristics 
(rate: manhours/project) 
1.2 Flight Planning actions and decisions include: 
- type of aircraft : piston engined, turbo charged piston engined, turbo prop, jet. 
- type of navigation method : adequate maps and simple tracking, no maps and tracking 
with photo checks, navigation systems 
- mission profile: speed of aircraft, its range and rate of climb, distance from local base, 
no. of runs, no. of sorties, flight line spacing, no. of films, gross no. of overlaps 
- obtain flight plan clearance 
2. MOBILIZATION inc. demobilization (project) 
Mobilization includes transit, set up, set down and customs clearance times. 
Mobilization may be considered in 3 phases: 
- 2.1 - Aircraft (rates: gross aircraft days/project and flight hours/project) 
- 2.2 - Freighted equipment and materials (rate: manhours/project) 
- 2.3 - support crew (rate: manday/project) 
3. SURVEY FLIGHT (consider part per line km., part per project) 
Flying for photographic Data/Orientation Data/Auxiliary Data includes transit time from 
base to target and return, flight hours over target and all standby time.

4. DATA PROCESSING (photograph) 
(rates: manhours/photograph and equipment hours/photograph) 
4.1.1 Processing of 1st Phase Photographic products. 
proof copies for acceptance and initial use in 
the field. 1st Phase Products include: black 
and white and colour film (developed) + 1 set 
of proof prints. Allow time for quality control 
and security aspects. 
4.2 Processing of Orientation Data/Auxiliary 
Data 
- position data (x,y) 
- altitude data (z,Az) 
(rate: manhours/photograph) 
4.1.2 Processing of 2nd Phase photographic Products 
Final diapositives and paper prints. Allow time 
for quality control and security aspects. 
(rate: manhours/photograph and 
equipment hours/photograph) 
5. ADMINISTRATION (photograph) 
Production of photo indices, index maps and flight 
reports. Time for the administration of flight results, 
film/photo library and the despatch of material 
(rate: manhours/photograph)
