I keep ripping stuff from this site, hope it helps:
ANTHROPOMETRIC MEASUREMENTS (NAVCRUIT 6110/7) print this page
In order to lower attrition rates and provide better quality applicants for Officer Candidate School and follow on training pipelines, CNRC is working closely with aviation community representatives in all areas. One particular area of concern is the anthropometrics measurements of pilots and naval flight officers. A strict process is used in Pensacola to measure applicants in order to determine which air frames they may qualify to fly. These measurements are based on several factors including height, weight, functional reach, buttocks knee length, and sitting height which are used to ensure the aviators safety on sitting in the cockpit as well as emergency ejections. These measurements include everything we have measured previously with the exception of buttock leg length. After studying the data the aviation community has come up with more accurate guidelines to apply for measurement ranges. The following are the accepted guidelines that should ensure compatibility with all pipelines. For applicants who may be close to limits I have access to the anthro website to enter data directly to check measurements. For qualified applicants who are possible selects who are close to limits we may also explore the option of sending them to Pensacola to check their measurements first hand.
FOR MALE SNA:
1. Thumb-tip Reach FR: 29.5 inches or greater
2. Buttock Knee Length: greater than 22 inches, but less than 26.5 inches
3. Sitting Height: greater than 34 inches, but less than 38.8 inches
FOR FEMALE SNA:
1. Thumb-tip Reach FR: 29.5 inches or greater
2. Buttock Knee Length: greater than 22 inches, but less than 26.5 inches
3. Sitting Height: greater than 33.5 inches, but less than 38.8 inches
FOR SNFO (MALE OR FEMALE):
1. Thumb-tip Reach FR: 27.5 inches or greater
2. Buttock Knee Length: 20.5 inches or greater
3. Sitting Height: 32 inches or greater
The following guidelines give directions as far as height concerns. Generally an applicant between 66" and 74" will be compatible for all pipelines.
FOR SNA:
1. IF 64 INCHES OR GREATER, BUT LESS THAN 76 INCHES:
- MOST LIKELY ANTHROPOMETRICALLY COMPATIBLE WITH AT LEAST TWO PIPELINES (SOMETIMES THREE)
2. IF GREATER THAN 76 INCHES, BUT LESS THAN 78 INCHES:
- MOST LIKELY ANTHROPOMETRICALLY COMPATIBLE WITH ONLY ONE PIPELINE (NORMALLY PROPS), BUT POSSIBLY TWO PIPELINES (DEPENDS ON SITTING HT).
3. IF LESS THAN 64 INCHES:
· SAFE ANTHROPOMETRICS COMPATIBILITY WITH ANY PIPELINE IS HIGHLY UNLIKELY!
· INDIVIDUAL IN QUESTION SHOULD BE SENT TO NOMI FOR OFFICIAL ANTHROPOMETRIC MEASUREMENT AND EVALUATION BY NASC FLIGHT PHYSIOLOGIST
FOR SNFO:
1. IF BETWEEN 64 INCHES AND 78 INCHES:
- MOST LIKELY ANTHROPOMETRICALLY COMPATIBLE WITH TWO PIPELINES (PROP & JET), BUT POSSIBLE AIRCRAFT RESTRICTIONS SUCH AS THE EA-6B FOR INDIVIDUALS WITH SITTING HEIGHTS GREATER THAN 37.4 INCHES.
2. IF BETWEEN 60 INCHES AND 64 INCHES:
MOST LIKELY ANTHROPOMETRICALLY COMPATIBLE WITH TWO PIPELINES (PROP & JET), BUT POSSIBLE AIRCRAFT RESTRICTIONS SUCH AS THE T-2, F/A-18, AND EA-6B FOR INDIVIDUALS WITH FUNCTIONAL REACHES LESS THAN 27.5 INCHES (T-REX ARMS).
Finally weight limits prohibit any training for applicants over 235 lbs. This is due to the safety concerns of ejection seats. No candidate will be allowed to enter training who is over 235 lbs.
