Operations at/near Aerodrome Flashcards
What is the difference between an MF aerodrom and an ATF aerodrome?
MF: Mandatory Frequency (You MUST have a radio to enter this space)
ATF: Air Traffic Frequency (A specific frequency for people to make calls on but a radio is not REQUIRED)
What circumstance dictates that an aerodrome be given a MF?
When it is busy enough to need pilots to talk to each other but not busy enough to require a control tower/control zone.
Will there be a ground station in operation at the aerodrome for which a MF has been established?
Sometimes yes and sometimes no. The CFS should be checked for this info, as it is more up to date than what is on maps.
If an MF aerodrom does have a ground station, what 4 types could they be?
1) FSS - Flight Service Station
2) CARS - Community Aerodrome Radio Sation (certified to conduct aviation weather observations and radio communications to facilitate AC arrivals and depatures)
3) Approach UNICOM (will have an AU designator in the CFS. Not very common.)
4) RCO - Remote Communications Outlet (The service they provide is called RAAS - Remote Aerodrome Advisory Services, and is provided by an FSS)
** A UNICOM without the ‘AU’ designator is not considered a ground station. (Debert) They can give very basic wx and traffic into but thats it.
If your radio fails and you’re headed into an MF, can you continue?
No. But if the MF has a ground station you could try calling them to get permission to enter that way.
What do IFR and VFR aircraft both need to enter an MF and what must they do once within the MF?
A working two-way radio (unless they have prior permission) and they should maintain a listening watch on the MF frequency
In most cases, an MF area extends…
…5NM and 3000 ft above aerodrome elevation (AGL).
Where are MFs normally establised?
Normally at airports with Class E control zones. Including airports that have Class C or D controls zones during hours of operation but that change to Class E when outside of those hours. (There may or may not be someone to talk to on the ground outside of these hours, the CFS would specify).
If an aerodrome has an MF with a ground station that is not on site (an RCO), what is the service that they provide called?
RAAS - Remote Aerodrome Advisory Services (provided remotely by an FSS)
Will people operating an MF give you clearances of any kind? To enter the CZ, to take off or land etc?
No. However, if the MF is a control zone ATC does still have jurisdiction. The person responsible for that MF may relay ATC clearances from the Area Control Center (ACC), usually only to IFR aircraft.
On a map, how do we know if an aerodrome has an MF and what the frequency is?
What does the 126.7 with a strikethough mean on a map?
It means it is receive only in that area. So you can listen but if you make a call no one will hear you or respond
How can you tell from a map that the MF you are calling is being monitored from a remote station? And who do you address when you call?
Under the aerodrom name, the location that is handling the MF is in brackets (see picture)
“Brandon Radio at Dauphin”
What aerodrome is an example of an RCO providing Remote Aerodrom Advisory Service (RAAS)?
The Dauphin/Brandon MF
What does the box on the map look like if the FSS for an MF is on site vs romote?
On site - Thick box
Remotely Operated - Thin box
How do you tell there is no ground station at an aerodome with on MF on a map?
There is no control zone or other info pointing you to a ground station to contact
What is a duplex frequency?
A FISE or FSS station that needs to, because of large distances, broadcast to an aircraft via a VOR. Only in the states but there are some near the border.
You talk (comms radio) to the FSS on the published ‘R’ frequency and then listen (nav radio) for the response on the published VOR Frequency
