- Flying is a strenuous and stressful
occupation. The diet of an average
man is not necessarily adequate for the
active flyer.
- Therefore nutrition of the flyer
requires special attention

Nutrition for Aircrew
• To promote the best performance, the diet
should aim in ‘Refueling’ the flyer with nutrients on
careful and regular basis as an a/c is refueled.
• Pilots should be physical, physiological and
psychological 100% fit.
• Adverse effects of incorrect feeding—under
feeding, over feeding or irregular feeding, are well
known—can cause human errors leading to A/C
accidents.

Types of Food
· The food which produces heat and
energy are called ‘fuel food’
(Fats and Carbohydrates.)
· Which builds and repairs tissues are
called ‘Body building’ food
(Proteins,minerals, salt and water.)

• Average caloric requirement of a
flyer is 3000-4000 cal/day in which:
• Protein should be 12% of the total
requirement
• Fats should be 35% of the total
requirement
• Carbohydrates 53% of the total
requirement
11. 1111
• Protein should be
120 gms which will give 500 cal
• Carbohydrates should be
500 gms which will give 2000 cal
• Fat
120 gms which will give 1080 cal
Total 3580 cal

Frequency and Quantity
• Avoid large meals before take-off as it
reduces mental alertness.
• Take light nourishing meal every 2-3
hours.
• Food should have high carbohydrate
content
• Avoid high fat/protein diet
• Least gas producing
14. 1414
· No flying on empty stomach, Fasting &
flying don’t go together.
· Blood sugar to be elevated before
flying
· Adequate amount of water should be
taken
16. 1616
(ii) In-flight feeding
• During long flight major meal to be

serves to satisfy emotional & Psychlogical needs
so messes & homes should take all care to
cook, serve hot, nutritious, well balanced &
appetizing food.

Caloric Needs
1. Basal Needs:
Calories needed daily by the body to
perform basic metabolic processes without
movement or activity.
= IBW in lbs x 10
178 x 10 = 1780 cal/day
19. 1919
2. Voluntary energy expenditure:
IBW x 13 for sedentary activity
IBW x 15 for moderate
IBW x18 for vigorous
Example: 6 ft man who is fairly sedentary
= IBW x 13
= 178 x 13
= 2314 cal/day
20. 2020
Ideal Body Weight (IBW)
We can determine IBW by the formula as:
Men: 106 lbs for first 5 ft + 6 lbs for each inch
over 5 ft
Example: Man 6 Ft tall = 106 lbs + ( 6x12) = 178
lbs.
Women: 100 lbs for first 5 ft + 5 lbs for each inch
over 5 ft.
Example: Women 5’ 4” tall = 100 lbs (5 x 4)= 120
lbs
21. 2121
Ideal Weight Range
Variation in body frame size:
10% +/- of IBW
178 lbs +/- 10% ------------- 160-196 lbs
120 lbs +/- 10% ------------- 108 – 132lbs
