SUMMARY OF RECOMMENDATIONS 
Porter J. Perkins 
NASA L e w i s  Research Center 
The major recommendations submitted b y  the three Uorkshop Panels 
are sumarized as follows: 
Panel on In-Flight Measurements recommended: 
1. Determination of the attenuation of ambient ozone in the c a b i n  
air systems for several different types o f  aircraft to further 
define the overall problem. (Required by design engineers) 
2 .  Evaluation of new ozone destruction devices during airline 
operations. 
3.  The health complaints compilation submitted at Workshop by 
representatives of the flight attendants be assembed w i t h  
measured ozone levels where available during a given flight. 
4. Statistical data on ambient ozone b e  provided for flight 
planning and design engineers. 
5. Determination o f  the dependency of ambient ozone attenuation 
on cabin load factors. 
6. Relative humidity i n  t h e  cabin be measured using the GASP 
water vapor instrument. 
Panel on Flight Planning to Avoid High Ozone recommended: 
- 
1. Measured ozone concentrations be correlated with regularly 
acquired meteorological variables to r e f i n e  present ozone 
forecast techniques. 
2. For more accurate and quantitative ozone forecasting, 
meteor01 ogi sts need : 
a. Better tropopause height reports. 
b. Understanding of relationship between high ozone 
and corresponding measured meteorological variables. 
c. NMC hemispheric meteorological data at all available 
levels including vertical motion f i e l d s  in t h e  
stratosphere. 
d. Satellite total ozone data.

3. Development and verification of an operational ozone model. 
(The Panel noted that  these recommendations would be limited 
to  f l i gh t s  during certain months of the year a t  higher lati tudes 
and a t  a l t i tudes a t  or above the tropopause. Available data 
indicate tha t  a large majority of l ights  are  a t  la t i tudes,  
a1 t i  tudes, and seasons where ozone exposure i s  a negligible 
r isk.  ) 
Panel on Ozone Destruction Techniques recommended: 
1 Development and characterization of new and improved materials 
t o  reduce weight, s ize ,  a n d  cost of ozone removal devices. 
2 .  Study of catalyst  bed lifetime. 
3. Study o f  influence of contamination on catalyst  bed 
efficiency. 
4. Study of kinetics and mechanisms by which ozone i s  destroyed 
on selected catalysts .
