Orientation

The map belows shows the three tarmac/pavements and six runways at EDDF Frankfurt.

• Runways (RWY) are numbered between 01 and 36 to indicate their magnetic heading (to nearest 10th degree).
• RWY 36 points north, 18 points south and 07 points NW.
• A runway can be used in both directions and therefore two names, eg RWY 18/36.
• If there are two or more runways, then L, C and R are appended for Left, Center, Right, eg 07L/25R.

EGLL: 09L/27R

The diagram shows the detail of the northen runway at Heathrow EGLL 09L/27R

• The DME (top center) is the location of the DME transmitter and is placed around half way down the runway.
• Below is the label indicating the RWY length, 3901M long and 50m wide and is designed to facilitate huge/heavy/fast aircraft, as well as small ones.
• The lines of the centre line are at ?m intervals
• Below the red T, are the green lights of the "threshold", a point at which aircraft are to land or take off after. 09L is a displaced threshold as its further onto the tarmac and a blast zone.
• Under the red P on both sides are the PAPI lights next to the "touch down zone", a point past the threshold and the safe landing area.
• TODO - elevation description
• TODO The lead in lights and the ILS position TODO

27R

Below is the google map view of 27R threshold

The image below is an aicraft fly-by of the northen runway 27R (right entry above)

• 27R is clearly marked on the runway tarmac in foreground.
  • The parallel 27L (09R threshold) is visible top left.
• T is the runway threshold and green lights. From the opposite side ie 09L these appear as red.
• The ILS localiser is positioned the other end of the runway near 09L threshold and red lights.
• D is the approx position of the DME transmitter halfway down the runway.
• The P are the PAPI lights, aircraft is high for fly-by.
• The Z is the target "touch down zone"

09L

The image below is a fly-by near the 09L threshold, a few moment after above (exiting to the left above)

• 9L is clearly marked on the runway for approaching aircraft
• The Threshold is marked with "red lights" and from the other side and landing, these are green.
• The threshold is "displaced" from the end of the actual tarmac and a line-up/blast zone.
• The ILS system is beyond the tarmac, the red/white coloured box.
• A taxi way is visible leading to or from the runway.
