segment.nAt higher altitudes it might be possible to receive two or more VORs simultaneously on the same frequency,making the signals unreliable for navigation.The MAA is the highest altitude that can be flown that guarantees that only one signal at a time will be received on a given frequency.Quiz#61.1.What are the takeoff minimums for aircraft with one engineWhat are the takeoff minimums for

unstaffed,remotely controlled,ground communications facility.Pilots at uncontrolled airports may contact ATC and FSS via VHF radio to a telephone connection to obtain an instrument clearance or close a VFR or IFR flight plan.They may also get an updated weather briefing.Pilots will use four“key clicks”on the VHF radio to contact the appropriate ATC facility or six“key clicks”to contact the FSS.The A/FD reference:(GCO)indicates that a ground communication outlet is available.Ground Communications Outlet(GCO)Communicationn nTWEB(Transcribed Weather Broadcast)n ncircled“T”in upper right hand

Outlet(RCO)is an unmanned air/ground communications facility,remotely controlled and providing UHF or VHF communications capability to extend the service range of an FSS.These frequencies provide direct radio communication with the associated FSS,(not ATC),rather than making an automated telephone connection as is the case with the GCO.The A/FD reference:(RCO)indicates that a remote
