Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Instrument Flight Rules

Jump to: navigation, search

Instrument flight rules (IFR) are regulations and procedures for flying aircraft by referring only to the aircraft instrument panel for navigation. Even if nothing can be seen outside the cockpit windows, an IFR-rated pilot can fly while looking only at the instrument panel. An IFR-rated pilot can also be authorized to fly through clouds, using Air Traffic Control procedures designed to maintain separation from other aircraft.

All scheduled commercial flights operate exclusively under IFR. Visual Flight Rules (VFR) are often used for sight-seeing flights, aerial photography, or lift services for parachute jumping. Pilots flying under VFR are not permitted to fly through clouds. Many non-commercial, private recreational aircraft also operate under VFR whenever the sky is clear. Under VFR, the pilot is primarily responsible for navigation, obstacle clearance and maintaining separation from other aircraft using the see-and-avoid concept.
