Critical area
From Wikipedia, the free encyclopedia
Critical area can refer to one of the following:
[edit] Aviation
In aviation, a critical area refers to a designated area of an airport that all aircraft must remain clear of when another aircraft is inbound on an ILS approach. These areas are used to protect against signal interference that may lead to navigational errors, or worse.
- Much larger than the critical area is the sensitive area. Aircraft and vehicles are not allowed in this area when Low Visibility Procedures are in force, since aircraft will be making autolands and therefore the accuracy of the guidance signals provided by the ILS is absolutely critical.
[edit] Integrated Circuits
In integrated circuit design, a critical area refers to the area of a circuit design wherein a particle of a particular size can cause a failure. It measures the sensitivity of the circuit to a reduction in yield.
