ZSA is a method of ensuring that the equipment installations within each zone of an aircraft meet adequate safety standards with respect to design and installation standards, interference between systems, and maintenance errors. In those areas of the aeroplane where multiple systems and components are installed in close proximity, it should be ...
Spare parts maintained at this level of repair are known as bench stock. Intermediate-level maintenance deployment can vary widely, and is highly dependent on desired operating conditions. In minimal maintenance concepts, there may be minimal or no I-level maintenance, a system known as two-level maintenance (O-level
The Particular Risk Analysis (PRA) looks for external events which can create a hazard such as a birdstrike or engine turbine burst. The Zonal Safety Analysis (ZSA) looks at each compartment on the aircraft and looks for hazards that can affect every component in that compartment, such as loss of cooling air or a fluid line bursting.
In May 1996, the FAA Aviation Rulemaking Advisory Committee (ARAC) was tasked with a review of harmonized FAR/JAR 25.1309, AC 1309-1A, and related documents, and to consider revision to AC 1309-1A incorporating recent practice, increasing complex integration between aircraft functions and the systems that implement them, [20] and the ...
A risk-reversal is an option position that consists of selling (that is, being short) an out of the money put and buying (i.e. being long) an out of the money call, both options expiring on the same expiration date. In this strategy, the investor will first form their market view on a stock or an index; if that view is bullish they will want to ...
Continuing airworthiness management organisation (CAMO) is a civil aviation organization authorized to schedule and control continuing airworthiness activities on aircraft and their parts [1] The scope of the CAMO is to organise and manage all documents and publications for Maintenance Organizations Part 145 and Part M approved, like ...
The FAA said alerts went off onboard letting pilots know they were close to another plane and 'corrective instructions' were issued to both flight crews
Failure Modes, effects, and Criticality Analysis is an excellent hazard analysis and risk assessment tool, but it suffers from other limitations. This alternative does not consider combined failures or typically include software and human interaction considerations. It also usually provides an optimistic estimate of reliability.
