lesson 9 Flashcards
What are the emergency frequencies
121.5mhz and 243mhz
Define mandatory frequency (MF)
Mandatory frequency (MF) is a very high frequency (VHF) used by aircraft operating in an MFA Mandatory Frequency Area
MFs are used to provide advisory service including traffic updates and runway surface conditions.
What is FISE?
Flight Information Services Enroute (FISE), or enroute frequencies,
are monitored by flight information centres (FICs) to provide and
receive information pertinent to aircraft in the enroute phase of
flight.
FISE frequencies are used for communicating information such as:
* Altimeter settings for nearest station reporting point
* Current weather in times of adverse weather conditions
* Significant inflight weather
* Accepting IFR position reports
* Providing limited airport advisory service
* Opening and closing flight plans
Define ATF
Aerodrome traffic frequencies (ATFs) are normally designated for
active uncontrolled aerodromes that do not meet the criteria to
have a mandatory frequency assigned.
An ATF is established to ensure that all radio-equipped aircraft
operating on the ground or within the area are listening on a
common frequency and following common reporting procedures.
ATFs are used by pilots only and are not monitored by flight
service stations.
What is the general broadcast frequency?
The general broadcast frequency, 126.7 MHz, is intended for pilots
to broadcast their position intentions in uncontrolled airspace.
FICs do not monitor 126.7 MHz, but they do have broadcast
capability on the frequency to broadcast urgent information.
Define ground frequency
Flight service stations provide positive control of vehicle traffic at
their airport. Vehicle control service is provided on the ground
frequency assigned to that particular flight service station.
