The FAA has published a Notice of Proposed Rulemaking (NPRM) that is applicable to certain Dassault Model Mystere-Falcon 900 series airplanes. This proposal would require revising the Abnormal Procedures section of the airplane flight manual to advise the flight crew to avoid use of certain display modes during approaches. This proposal also would require replacing certain symbol generators of the Electronic Flight Information System (EFIS) with modified symbol generators. The FAA claims this action is necessary to prevent distraction of the flight crew during a critical phase of flight due to certain EFIS displays flashing or going blank, which could result in loss of control of the airplane.
