GIBRALTAR


Challenging approach
The fi nal approach is also a li le unusual.
Most commercial fl ights originate in
the UK and they typically pass over the
northern Spanish coast near Santander.
Inbounds then let down southward to
the resort of Marbella, east of Gibraltar,
which they cross at around 10,000ft.
From there landings towards the west
make a wide right turn onto fi nal, while
the procedure for easterlies involves
fl ying further south and then making a
180 o right turn around the south of the
colony and the Rock to avoid overfl ying
Spain again. Positional accuracy is
required on the northerly right base to
Runway 09 due to its proximity of 2,500ft
hills on the mainland, and once an
aircraft is 3nm southwest of the airfi eld
it makes another 90o right turn onto a
short straight-in approach.
Surprisingly Gibraltar does not have
any instrument approaches. Inbound
traffi c is typically off ered a radar service
for the initial phase of the descent, and
then provided with an SRA (surveillance
radar approach) to a visual decision
point 3nm from touchdown. At that
point, pilots must be able to see the
runway or must execute a missed
approach. The typical lighting systems
found at many airfi elds are also absent.
However, there is illumination on the
extended centrelines, comprising a
DayGlo-painted fl ashing buoy 4,500ft


(1,372m) from the sea wall on Runway 09.
Single white fl ashing lights at 9,000ft
(2,743m), 6,000ft (1,829m) and 3,000ft
(914m) are available for Runway 27.
There are also strobes at both thresholds
that are switched off when an inbound
aircraft is on 2nm fi nal, and the runway
ends are marked with blue lights.

Turbulence
The wind can create turbulence and
shears on the airfi eld or on fi nal approach.
The offi cial guidance to pilots off ers the
following advice: “Turbulence around The
Rock is infl uenced by both the surface wind
and the 1,000ft wind. Generally, a 1,000ft

wind of less than 15kts does not produce
any signifi cant turbulence. However, with
a wind direction between 130o and 240o
and a speed in excess of 15kts the severity
of the turbulence increases as the wind
speed increases. In some cases, the
turbulence may make conditions dangerous
or impossible for landing. Wind speeds
above 25kts from 090o – 110o may cause
severe turbulence and marked variations
in airspeed during the la er stages of an
approach to Runway 09.”
The aeronautical charts add that
turbulence is likely across the entire airfi eld
when the winds are from the south (170o


  • 220o) and will be more prevalent on the
    Runway 09 fi nal approach path when the
    wind comes from the southeast (130o – 170o).
    Should a south-westerly be blowing (200o

  • 230o), up- and down-drafts are most likely
    on short fi nal to Runway 27.
    These issues have – perhaps unfairly

  • led to Gibraltar Airport being rated as
    a diffi cult airfi eld to operate into and out
    of. Last year its CEO Terrence Lopez told
    Airports of the World that he does not
    support that view: “I do not agree with that
    position, although I am fully aware that
    under certain meteorological conditions
    some approaches can be challenging. The
    prevailing winds are from the east and
    west, and these have no adverse eff ect on
    fl ight operations.
    “Occasionally we get winds from the
    southwest, which creates a possibility of


turbulence due to the location of the Rock
and the runway, but the charts include all
the information and guidance for pilots. In
addition, airlines have their own limitations
which they adhere to, as safety is everyone’s
top priority. Thankfully south westerly winds
do not occur very often and when they do, it
tends to be only for short periods.
“Gibraltar is classifi ed as a Cat C airport,
similar to Funchal [see P28] and Innsbruck
[see P16]. This means additional training is
required before a fl ight crew can operate
here. These airports have their own
challenges, be it surrounded by terrain or by
large conurbations. We are no diff erent and
no more diffi cult to either of those.”
There are a number of issues currently
facing Gibraltar and its population, which
has remained resolutely pro-Britain for
more than 300 years. Not least is the UK’s
impending exit from the European Union,
but Spain also still lays claim to the territory
and it could yet become a bargaining
chip in the Brexit negotiations.
One thing is for certain – the
lack of open space in the
area means its airport
will remain challenging
to aviators when the
wind blows, even
if the problems it
creates are not
too extreme.
