We have also produced interactive Google maps for your convenience. 

The first map shows the existing departure routes (SIDs) which have been used at Glasgow Airport for decades plotted as purple and pink lines. The map allows you to zoom in and out.

The second map shows the proposed departure routes (SIDs) plotted as cyan blue lines and allows you to zoom in and out. The lines represent the central nominal track of these highly accurate RNAV-1 routes.  

Whilst the blue routes are shorter than the existing pink/purple routes, both end at an altitude of 6,000 feet. In moving to the proposed routes, aircraft will not have to carry extra fuel in the anticipation of being held down below 6,000 feet for longer (fuel burn at lower altitudes is typically greater). It is anticipated they will experience a more efficient and earlier climb to a higher altitude.

How to use the map: 

1)      Select the frame icon (at the top right-hand corner of the map) to open the map up to full screen;

2)      Scroll or Zoom in and out of the map using your mouse to your point of interest; or

3)      Select the magnifying glass icon and type your postcode or place name into the text box and click enter (the map should automatically find your location but you may then need to zoom out to see what is in your vicinity);

4)      Each of the routes is labelled and these labels can be seen if you left click on the route lines using your mouse;

5)      The second map only - The marker icons show spot heights of locations along the routes to provide an indication of the height above ground level (agl) that the aircraft would be.  These can be viewed by a left mouse click on the marker icon.  

Important Please Note: These indicative heights have been worked out by taking the Procedure Climb Gradient (a rate that most aircraft will exceed) and measuring the distance travelled to each point to establish the altitude (point above mean sea level).  The elevation (or height) of the ground is then subtracted from this altitude to give a height.  That is why the markers at the end of the SIDs do not say 6,000 feet as it is 6,000 feet (altitude) minus the height of the ground beneath the end of the SID.

Existing departure routes (SIDs)

The following two maps show the existing flight paths (pink tracks), the tracks the aircraft are actually flying (yellow tracks) and the routes we are proposing (cyan blue).

Proposed departure routes (SIDs)

The following tables and information are included in our consultation document on pages 41 -42.

Some of the environmental information we have provided relates to theoretical maximum noise levels that may be experienced by people on the ground from an aircraft flying directly overhead. This is known as Lmax. The unit of measurement is A-weighted decibels (dB(A)) (loudness of noise matched to the frequency response of the human ear). 

The Civil Aviation Authority (CAA) Environmental Research and Consultancy Department (ERCD) has produced Lmax data as a function of an aircraft height above the ground (together with the degree of uncertainty of the data) for representative groupings of aircraft. We have extracted data from ERCD pertinent to the aircraft types that are likely to operate from Glasgow Airport and utilise the SID procedures. Table 1 provides a comparison to the level of noise that can be expected. 

The aircraft types predominantly operating services from Glasgow Airport (Airbus A319 and Boeing B737-800) are grouped together with other comparable aircraft for noise measurement purposes as detailed in Table 2. 

Table 3 gives the Lmax noise levels that the CAA noise modelling has developed for these aircraft groups for departing aircraft as a function of height above the ground. 3.11.5 From this you can see that an A319 or a B737-800 passing 5,001 feet (height above the ground) would result in an expected noise level of 63-60 dB(A) Lmax (equivalent to the noise level of conversational speech,1 metre away).
