NOTAM ALPHA 7th June 2007

On the 7th of June 2007 due to magnetic variation, the runway identifiers at Manchester Ringway airport (EGCC), have changed from 24/06 to 23/05. You can see all these updates on the new charts published for Manchester (EGCC) on the AIP website.

NOTAM DELTA 28th September 2007

The following NOTAM supercedes NOTAM BRAVO issued on 11th September 2007.

London Heathrow (EGLL):

Frequency 118.7MHZ is now associated with the Northern Runway (09L/27R)
Frequency 118.5MHZ is now associated with the Southern Runway (09R/27L)

To facilitate this change, the IvAc callsigns for the tower positions have changed.

From 2300Z on Friday 28th September 2007, EGLL_A_TWR and EGLL_D_TWR positions will no longer exist. These have been replaced by:

EGLL_N_TWR (Tower responsible for the Northern Runway (09L/27R)) - AIR NTH
EGLL_S_TWR (Tower responsible for the Southern Runway (09R/27L)) - AIR STH

Before logging onto the network as a Heathrow Tower Controller, you must now check the runway in use for LANDING using the Preferential Runway Procedures and weather information. This is to ensure that you log on with the correct callsign and frequency.

If the landing runway is 09L/27R, log on as AIR NTH.
If the landing runway is 09R/27L, log on as AIR STH.

The UK Division website has been edited to show these changes. We recommend you read the following web pages to fully understand them:

NOTAM ECHO 15th October 2007

Changes to UK Instrument Landing System (ILS) Phraseology

In the UK, the standard ICAO phraseology "Cleared for ILS Approach" has never been used. This is due to the procedure design, UK Airspace complexity and lessons learned from flight safety related incidents involving traffic conflicts caused by aircraft descending below their cleared level.

Problems have arisen with the current ILS clearance system, where, on occasions, pilots have not received clearance to descend in sufficient time to follow the ILS glideslope and this has led to unstable and rushed approaches. To reduce the likelihood of pilots not receiving descend clearance in sufficient time, new phraseology is to be introduced. This new phraseology provides, in a single transmission, clearance to descend on the ILS once established on the localiser.

With effect from 15th November 2007, the following revised ILS phraseology will be used for radar vectored ILS approaches in the UK:

a) ATC Instruction:

(Callsign and vectoring instructions as at present)

followed by

"when established on localiser, descend on ILS (QNH)"

b) Pilot Response:

(Read back vectoring instructions as at present)

followed by

"when established on localiser, descend on ILS (QNH), (callsign)"

Example:

"BAW123, turn right heading 245, when established on the localiser (Runway XX), descend on the ILS"
"Turn right heading 245, when established on the localiser (runway xx), descend on the ILS, BAW123"

- QNH can be omitted if it has already been passed once during the approach
- Runway number should be added in the transmission at airports with more than one runway

Pilots will maintain the last assigned level until established on the ILS glideslope. It is not necessary for pilots to report when descending on the ILS.

When a controller deems it necessary, for traffic separation purposes, to ensure that an aircraft joining the ILS does not commence descent until specifically cleared by the controller, the following alternative should be used:

a. ATC Instruction:

(Callsign and vectoring instructions as at present)

followed by

"report established on localiser, maintain (level )"

b. Pilot Response:

(Readback vectoring instruction as at present)

followed by

"report established on localiser, maintaining (level ) (callsign)"

followed by

"Localiser established (Callsign)"

c. Subsequent ATC Instruction:

"(Callsign) descend on ILS (QNH)"

d. Subsequent pilot response:

"(QNH) - descend on ILS (callsign)"

Example:

"BAW123, turn right heading 245, report established on localiser (runway XX), maintain 3000ft"
"Turn right heading 245, report established on localiser (runway XX), maintaining 3000ft, BAW123"
---
"localiser established, BAW123"
"BAW123, descend on ILS"
"Descend on ILS, BAW123"

- QNH can be omitted if it has already been passed once during the approach
- Runway number should be added in the transmission at airports with more than one runway

Pilots must maintain the last assigned level until either a clearance to descend to a lower level or an aircraft has been told to descend following the ILS.
