Special conditions: modified Boeing Model 767-200 and -300 series airplanes; installation of a medical oxygen system utilizing liquid oxygen--Federal Aviation Administration. Final special conditions; request for comments.

These special conditions are issued to E-Systems for design of Civil Reserve Air Fleet aeromedical evacuation ship set kits used to modify Boeing Model 767-200 and -300 series airplanes. Removal of existing passenger seats and installation of the kit will result in these airplanes being equipped with an aeromedical evacuation interior that can accommodate up to 111 litter patients and their attendants. The aeromedical evacuation ship set kit includes an additional oxygen system, utilizing liquid oxygen for storage, that provides medical oxygen for the litter patients. The applicable regulations do not contain adequate or appropriate safety standards for the design and installation of liquid oxygen systems. These special conditions contain the additional safety standards which the Administrator considers necessary to ensure that the design and installation of the liquid oxygen system is such that a level of safety equal to that intended by the applicable regulations is provided.

[Pseudophakia and aptitude of aviation personnel].

UNLABELLED: Because of sensorial disruptions, aphakia post-cataract surgery is a cause of unfitness for the job of aeronautics flying personnel. Its correction thanks to intraocular lenses and a correct functional check-up permit to reconsider the fitness through a derogation given by the competent authorities. EQUIPMENT AND METHODS: The authors realized a retrospective study on the 5 last years. 27 flying personnel, 24 to 76 years old, went through a cataract surgery with implantation. The check-up includes a chemical exam completed by a morphoscopic, coloured and spatial study. RESULTS AND DISCUSSION: The files are more or less well-documented according to their origin. The flying personnel have an average of 4,010 flying hours. The average post-operative hindsight is 30 months. 3 wear intraocular lenses of rear chamber among which 1 is multifocal. 7 were examinated at the CPEMPN with satisfying morphoscopic, coloured and luminous sense compatible with the fitness. 4 are declared permanent unfit (1 professional pilot with bad results, 1 private pilot with other pathologies, 1 inexperienced stewardess getting through the admission visit with insufficient post-operative hindsight, 1 professional pilot declared unfit for its military activity in the reserve). 4 are qualified with restriction. 20 are qualified without restriction. CONCLUSION: The correction of aphakia with intraocular lenses permits in most cases to obtain good functional results compatible with the flying aptitude.

[Arterial hypertension as a problem of medical certification of the flying personnel in civil aviation].

Subjects of the longitudinal study (1974-1996) were about 300 pilots who participated in international transmeridian flights. Arterial hypertension (AH) diagnosed in 29 pilots was the main cause for their disqualification. They made up 16.8% of the total number of medically disqualified persons. The flight surgeon of the corps consulted 26 pilots with elevated arterial pressure (AP) or 8.8% of the corps roll. Clinical examination revealed the "white coat" hypertension in five pilots (1.7% of the corps roll). Percentage of pilots disbarred in the course of preflight physical check for the reason of high AP amounted to 32.7; hence, elevated AP was the most frequent cause for disbarring. The circannual distribution of elevated AP measured during the preflight medical check correlates with the challenges of either making the transmeridian flights in cold seasons due to the contrast of the climatogeographical zones or more tense flight schedule in summer. The greatest concern arise pilots whose AP was found normal during the preflight check but who were later on disqualified with the diagnosis of the 2nd degree hypertension as representatives of this cohort were documented to suffer myocardial infarction and acute disturbance of the cerebral circulation in the rest periods.
