OFFICE OF THE AIR SURGEON CAREFUL SELECTION MEANS BETTER 
PILOTS, BOMBARDIERS, AND NAVIGATORS 
Men are selected for Aviation Cadet 
training after thorough physical and 
psychological examinations. Final 
classification of those who meet 
physical and aptitude requirements 
is based upon three factors. 
Preference for pilot, bombardier, 
or navigator training ’

On the following pages is presented graphically a description of the 
men who are being trained to fly for the Amy Air Forces, Research 
findings from the Air Surgeon's Aviation Psychology Program are summarized 
showing how success in aircrew training -Car- be predicted. PRESENT AGE Ri* :UIREM£NT3 FOR AVIATION CADETS 
A IE SATISFACTORY 
REQUIREMENTS PI FITTING MEN WITH ALL DEGREES OF 
FORMAL EDUCATION ,ND BOTH MARRIED AND SINGLE MEN TO 
APPLY FOR AVIA: CON CADET TRAINING ARE JUSTIFIED 
Information about the Age and Education of Aviation Cadets is given 
in the following section. The relation of Age and of Education to success 
in pilot training is press ted in several charts. 
The comparative succc s of single men and married men in pilot train- 
ing is also shown. 
The fact that youngei men are slightly more successful in primary 
and basic pilot training • 5 encouraging in view of the fact that the ma- 
jority of recent Aviation Jadet candidates are quite young. There are 
no restrictions on Aviatii .1 Gadet applicants with respect to educational 
status; results confirm the soundness of this policy. The present policy 
of admitting married men to Aviation Cadet training is also shown to be 
Justified.
