Question: A minimum safe altitude (MSA) is published for emergency use on instrument approach charts. Flying at or above the MSA will guarantee how many feet of obstacle clearance?
Answer: The MSA provides at least 1,000 feet of clearance over all obstructions within the radius published on the chart. The radius is typically 25 nautical miles but may be expanded to 30 nm where appropriate. (Source: Instrument Procedures Handbook Chapter 5, Page 18)

Rockwell Collins, which purchased ARINC last year, has combined the flight support services offered by it and ARINC, and enhanced onboard systems for passengers and pilots.
When you brief an instrument approach with circling minima, can you explain whether it has a standard circling approach maneuvering radius, or an expanded one?
Safe Flight has developed an icing detector that senses icing conditions before ice develops, allowing pilots to escape.
