Annex 10 Flashcards
Since visual reference is essential for the final stages of approach and landing, the installation of a radio
navigation aid does not obviate the need for
visual aids to approach and landing in conditions of low visibility.
The ILS shall comprise the following basic components:
a) VHF localizer equipment, associated monitor system, remote control and indicator equipment;
b) UHF glide path equipment, associated monitor system, remote control and indicator equipment;
c) an appropriate means to enable glide path verification checks
An ILS glide path bend is an
aberration of the ILS glide path with respect to its
nominal position.
Considerations of interference between inner and middle markers, and the minimum operationally acceptable
time interval between inner and middle marker light indications, will limit the maximum height marked by the inner marker
to a height on the ILS glide path of the order of
37 m (120 ft) above threshold for markers sited within present tolerances in
Annex 10. A study of the individual site will determine the maximum height which can be marked, noting that with a typical
airborne marker receiver a separation period of the order of 3 seconds at an aircraft speed of 140 kt between middle and inner
marker light indications is the minimum operationally acceptable time interval.
GNSS en route Specific availability requirements for an area or operation should be based upon:
a) traffic density and complexity;
b) alternate navigation aids;
c) primary/secondary surveillance coverage;
d) air traffic and pilot procedures; and
e) duration of outages
The international aeronautical telecommunication service shall be divided into four parts:
1) aeronautical fixed service;
2) aeronautical mobile service;
3) aeronautical radio navigation service;
4) aeronautical broadcasting service.
Flight safety messages shall comprise the following:
1) movement and control messages [see the PANS-ATM (Doc 4444)];
2) messages originated by an aircraft operating agency or by an aircraft, of immediate concern to an aircraft in flight
3) meteorological advice of immediate concern to an aircraft in flight or about to depart (individually communicated or
for broadcast);
4) other messages concerning aircraft in flight or about to depart.
Flight regularity messages shall comprise the following:
1) messages regarding the operation or maintenance of facilities essential for the safety or regularity of aircraft
operation;
2) messages concerning the servicing of aircraft;
3) instructions to aircraft operating agency representatives concerning changes in requirements for passengers and crew
caused by unavoidable deviations from normal operating schedules. Individual requirements of passengers or crew
shall not be admissible in this type of message;
4) messages concerning non-routine landings to be made by the aircraft;
5) messages concerning aircraft parts and materials urgently required;
6) messages concerning changes in aircraft operating schedules.

one two thousand
When an aircraft station fails to establish contact with the appropriate aeronautical station on the designated
channel, it shall attempt to
establish contact on the previous channel used and, if not successful, on another channel
appropriate to the route. If these attempts fail, the aircraft station shall attempt to establish communication with the
appropriate aeronautical station, other aeronautical stations or other aircraft using all available means and advise theaeronautical station that contact on the assigned channel could not be established. In addition, an aircraft operating within a
network shall monitor the appropriate VHF channel for calls from nearby aircraft.
“TRANSMITTING BLIND”
Distress:
a condition of being threatened by serious and/or imminent danger and of requiring immediate assistance.
Urgency:
a condition concerning the safety of an aircraft or other vehicle, or of some person on board or within
sight, but which does not require immediate assistance.
MAYDAY , preferably
spoken three times, the distress message to be sent by an aircraft in distress shall:
a) be on the air-ground frequency in use at the time;
b) consist of as many as possible of the following elements spoken distinctly and, if possible, in the following order:
1) name of the station addressed (time and circumstances permitting);
2) the identification of the aircraft;
3) the nature of the distress condition;
4) intention of the person in command;
5) present position, level (i.e. flight level, altitude, etc., as appropriate) and heading.
Simplex.
A method in which telecommunication between two stations takes place in one direction at a time.
