Proposed Change #2 to FAA P-8110-2, Airship Design Criteria

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of availability of Proposed Change #2 to FAA P-8110-2, 
Airship Design Criteria (ADC); request for comments.

-----------------------------------------------------------------------

SUMMARY: This proposed change adds the requirements for fly-by-light 
control systems. We propose to add two new paragraphs to the ADC that 
cover concerns related to optical couplings and optical degradation. We 
do not consider loss of primary flight controls critical to continued 
safe flight and landing in airships, because they essentially become 
free balloons if they lose controllability.

DATES: Comments must be received on or before March 21, 1994.

ADDRESSES: Mail or deliver comments on the Proposed Change #2 to FAA P-
8110-2, Airship Design Criteria (ADC), to: Federal Aviation 
Administration, Small Airplane Directorate, Aircraft Certification 
Service, Standards Office (ACE-110), 601 East 12th Street, Kansas City, 
Missouri 64106.

FOR FURTHER INFORMATION CONTACT:
J. Lowell Foster, Aerospace Engineer, Standards Office (ACE-110), Small 
Airplane Directorate, Aircraft Certification Service, Standards Office 
(ACE-110), 601 East 12th Street, Kansas City, Missouri 64106.

comments invited: Interested parties are invited to submit such written 
data, views, or arguments as they may desire. Commenters must identify 
the report number (FAA-P-8110-2), and submit comments to the address 
specified above. We will consider all written comments received on or 
before the closing data for comments before we revise the ADC. The 
proposed changes to the ADC and comments received may be inspected at 
the Standards Office (ACE-110), 1201 E. Walnut, Suite 900, Kansas City, 
Missouri, between the hours of 7:30 a.m. and 4 p.m. weekdays, except 
Federal holidays.

background: The requirements for a control system not directly 
(mechanically) connected to the control surface are applicable to both 
fly-by-wire and fly-by-light. The fiber optics used in fly-by-light 
systems, though immune to some of the problems associated with fly-by-
wire systems, has its own set of problems. Those problems are addressed 
in this change.
