MATS 1 Supplementary Instructions and ORS Flashcards
SI 493 2015/02 Airprox Involving Small Unmanned a/c
-Most airproxs happen at abov 1,500ft, this is higher than people can maintain visual contact with the A/C (although they can be specifically authorised to not need this) and the airspace around it. -This SI therefore reinforces and adds to the current reporting procedures to try and remedy this, the police must also be informed as well as completing the reqeusite forms.
SI 493 2015/04 Change in definition of minimum fuel
ICAO changed definition of minimum fuel to; The term used to describe a situation in which an aircraft’s fuel supply has reached a state where the fligth is committed to land at a specific aerodrome and no additional delay can be accepted.
SI 493 2015/05 Change to the use of runway designators
UK aligned with ICAO recommendations and now includes the runway designator in RTF messages for landing, taking off touch and go’s etc, except where local safety assurance and oversight procedures say you shouldn’t.
SI 493 2016/01 Change to the method of determining the transition level
Transition level is no longer just the lowest usable flight level above the transition altitude. It is now; -Transition Level is the lowest Flight level available for use above the transition altitude and shall be located a nominal 1,000ft above the transition altitude to permit the transition altitude and the transition level to be used concurrently in cruising flight, with vertical separation ensured. Except where an alternative means of calculating the transition level is detailed within local instructions, the transition level may be determined from the table in Appendix A as follows; 1)Within CAS by the controlling authority, where it will normally be based on the QNH of the major aerodrome. 2)Outside CAS by the aerodrome operator where it will be based on the aerodrome QNH.
SI 493 2016/02 Removal of section 8 chapter 2- Air Traffic Licensing
To avoid duplication of text this section was removed as it can instead be found in CAP 1251
SI 493 2017/01 Amendment to Bomb warning procedure
A large amendment to section 5 regarding bomb threats, not sure if i would need to know this.
SI 493 2017/02 Implementation of SERA part C Phase 1
Impacts; a) A number of new definitions
b) Changes in SERA references
c) Insertion of additional SERA references
d) Amendment of VFR and SVFR clearance procedures -
References to the ANO 2009 have been amended to reflect entry into law of ANO 2016 Change to Chapter 8 SVFR flight;
SVFR minima;
- Lays down the Met conditions below which clearances will be withheld and SVFR a/c already inbound informed and asked for their clearance requirements.
- Lays down the Met conditions below which controllers will not issue SVFR clearances to a/c operating in the ATZ, circuit or landing/taking-off.
- Allows SVFR to transit CTR outside of ATZ, circuit etc as long as the flight vis is still 1500m -ORS 1125 permitting SVFR at night -Lays down exemptions to SVFR minima (Helimed, police etc)
Section 2 chp 1 VFR minima
- Lays down the Met conditions below which clearances will be withheld and VFR a/c already inbound informed and asked for their clearance requirements.
- Lays down the Met conditions below which controllers will not issue VFR clearances to a/c operating in the ATZ, circuit or landing/taking-off.
- ORS 1195 permitting VFR to fly in Class D outside ATZ etc with lower VFR minima (COCSIS)
- Lays down exemptions to VFR minima (Helimed, police etc) Allows EASA flight crew licence holders (including student licence holders who have completed the MET exams) to assess whether the Met conditions satisfy the minima for either SVFR or VFR flight.
Chapter 5;
-Defines what a/c are provided with what services (ie who is separated for whom and what flight rules are allowed in certain CAS)- this appears unchanged.
Chapter 3- Speed limit
- Speed limit of 250KIAS below 10,000ft, except;
a) Flights in class A and B airspace
b) IFR flights in class C airspace
c) VFR flights in class C when authorised by an ATC unit in accordance with MATS pt 2.
d) For exempted flights in Class D airspace when authorised by an ATC unit in accordance with MATS pt 2.
e) Test flights in accordance with specified conditions.
f) A/c taking part in flying displays when authorised by the CAA
g) A/c subject to a written permission granted by the CAA
h) State a/c such as military
Pilots responsibilities when flying SVFR;
1) Must comply with ATC limitations
2) Responsible for ensuring that he flies at an indicated airspeed of 140kts or less
3) Responsible for ensuring that his flight conditions enable to remain COCSIS
4) Responsible for ensuring that he flies within the limitations of his licence.
5) Comply with the relevant ROA low flying restrictions.
6) Obtain prior permissions before penetrating an ATZ.
Changes to Definitons;
- Air Traffic Surveillance Service= A service provided directly by means of an ATS surveillance system.
- ETA for a VFR flight= When is arrives over the aerodrome.
Sets out the VMC table
SI 493
Surveillance Separation Minima: Unknown Aircraft
- 5,000ft vertical sep from unknown traffic or traffic with unverified Mode C
- Also breaks down what to do if a radio fail a/c is not responding to instructions.
SI 493 2017/05
SERA Part C Phase 2 implementation
Instrument Approach Procedures
Redefined as;
A series of predetermined manoeuvres by reference to flight instruments with specified protection from obstacles from the initial approach fix, or where applicable, from the beginning of a defined arrival route to a point from which a landing can be completed and thereafter, if a landing is not completed, to a position at which holding or en-route obstacle clearance criteria apply. Instrument approach procedures are classified as follows;
a) Non precision approach (NPA). An instrument approach procedure designed for 2D instrument approach operations type A.
b) Approach procedure with vertical guidance (APV). A performance based nav (PBN) instrument approach procedure designed for 3D instrument approach operations type A.
c) Precision approach (PA) procedure. An instrument approach procedure based on Nav systems (ILS, MLS, GLS and SBAS Cat 1) designed for 3D instrument approach procedures.
- Also lays out ILS categories.
Cancellation of IFR flight plan
- No invitation to change flight plan is to be made by ATC
- Cancellation of IFR flight plan in Class E airspace means no ATC service
- IFR cancellation phraseology
SERA referencing changes in intermediate approaches including for Wake turbulence separation.
ATC clearances
Numerous changes in references
Conditional clearances
Lays down phraseology- “C/S behind the landing (a/c type), via (holding point), runway (designator), line up behind”
Flight levels
Flight level definition has changed;
Flight levels are measured with reference to the standard pressure setting of 1013.25hPa. Consecutive IFR cruising levels above the transition altitude are separated by pressure intervals corresponding to 1000ft in the ISA up to and including FL410 and by pressure intervals corresponding to 2000ft above FL410
Transition layer definition has changed;
Transition layer is the airspace between the transition altitude and the transition level. WIthin the UK the first available flight level above the transition altitude is seperated from the transition altitude by a minimum pressure interval corresponding to 1000ft.
Procedures at Aerodromes
The transition altitude must be passed to the pilot in due time prior to his a/c reaching it during descent, either by voice comms, ATIS broadcast or data link.
Operations normal
Pilot transmissions containing the RTF phraseology “Operations normal” may be associated with aerial activities where the flight is receiving an ATIS, is required to operate within the area of responsibility of a single ATSU for prolonged periods. Such transmissions may occur following a period of inactivity of 30 mins between the ATSU and the pilot receiving the ATS. The pilots declaration of “Operations normal” is used to inform the ATSU that his flight is progressing according to plan.
- In Europe the use of operations normal is applicable to all sectors of flight over mountainous terrain or sparsely populated areas, including sea areas. However use of this procedure in other situations is permitted in accordance with MATS pt 2.
- Controllers who do not receive an “Operations normal” report when expected should attempt to contact the pilot using the following phrase: “C/S confirm operations normal?” - if pilot does not respond after 3 attempst controllers should intiate overdue action.
A/c observations and reports
Added an extra type of report for pilots to report;
6) Pre-eruption volcanic activity or volcanic eruption.
ORS 1174
