2、IFR flight plans in controlled airspace. Central authority for issuing IFR clearances Provide nationwide monitoring of each IFR flight - enroute mostlyARTCC Priorities 1 Safe separation of known IFR traffic 2 Issuance of safety alerts 3 Workload permitting, separation of VFR aircraft Before you can

3、operate in controlled airspace under IMC conditions, you MUST:file an IFR flight planANDhave received a clearance Plan to file your flight plan at least 30 minutes prior to departureRequesting Your Clearance Field has Control TowerGround ControlClearance Delivery if appropriate Field only served by

6、 stay within +/- 10 knots of it. Know your regulations Know your currency status Know your airspace Know your aircraft requirementsSeparation is Good! Remember ATCs first priority is separation of IFR traffic. When IFR in VMC:always use “see and avoid”if possible, ATC will separate you from VFR traf
