Instrument Landing System(ILS)

A. GENERAL DESCRIPTION
Instrument landing system (ILS) facilities are a highly accurate and dependable means of navigating to the runway in IFR conditions. When using the ILS, the pilot determines aircraft position primarily by reference to instruments. The ILS consists of:

1. the localizer transmitter;
2. the glide path transmitter;
3. the outer marker (can be replaced by an NDB or other fix);
4. the approach lighting system.

ILS is classified by category in accordance with the capabilities of the ground equipment. Category I ILS provides guidance information down to a decision height (DH) of not less than 200 ft. Improved equipment (airborne and ground) provide for Category II ILS approaches.
A DH of not less than 100 ft. on the radar altimeter is authorized for Category II ILS approaches.
The ILS provides the lateral and vertical guidance necessary to fly a precision approach, where glide slope information is provided. A precision approach is an approved descent procedure using a navigation facility aligned with a runway where glide slope information is given. When all components of the ILS system are available, including the approved approach procedure, the pilot may execute a precision approach.

As economy expands, airlines hope for another year of growth

India' s airlines enter 2011 comforted by double-digit
growth in passenger traffic that
promises to stretch into a second year
as the economy grows at a faster pace,
helping support their ambitious
expansion plans. Jet Airways (India) Ltd, Kingfisher
Airlines Ltd, IndiGo run by InterGlobe
Aviation Ltd, Air India Ltd and smaller
airlines have carried a record 50
million passengers in 2010, an
increase of 18% over the year-ago period.
And, after posting a combined loss of
$2 billion (Rs.9,020 crore today) in
each of the previous two years,
airlines are set for a profit of $300
million in the fiscal year to March 2011, estimates the consultancy Centre for
Asia Pacific Aviation (Capa).

Flight delays costing airlines Rs. 25-50 Crore

New Delhi: Airlines which were ideally
expecting to ring in the holiday
season with festive flourish may
instead have to deal with a rude
shock, courtesy the weather.
Dense fog has gripped North and East India and heavy snowfall has crippled
international air travel, thus, throwing
airline schedules off gear. Airlines are
expected to lose Rs. 20-50 crore due
to this.
"With weather playing havoc, you have to suffer losses due to delay, re-
routing getting to an airport where
you don' t have facilities...all this account for losses and Rs. 20-50 crore
is an average which airlines lose
during the fog period," said Ankur
Bhatia, executive director of Bird
Group. Long haul international
operations too are not faring well. Reeling under intense snow in Europe
and US, Indian carriers had to cancel
flights as operations are being
brought to a standstill. Airlines are
providing refunds for the ticket for
flights which were cancelled.

Air India to train staff in bid to improve its on-board services

In his first media interview after being appointed Air
India’ s chief training officer, Stephen Sukumar said the airline is in talks with
some of the world’ s best hotel chains to train its employees in an attempt “ to bring back some of the once
legendary shine of Air India on-board
service” . And for ground staff, the airline has
developed training programmes
benchmarked to those of other Star
Alliance members, he added.
By the middle of next year, Air India
will join Star Alliance, a global grouping of airlines with 27 members
including Lufthansa German Airlines
and Continental Airlines Inc.
And the airline has renegotiated all its
training contracts and lowered total
training costs by 29%, when compared with the last fiscal year,
according to Sukumar.
However, the airline’ s annual report doesn’ t have a break-up of the amount spent on training.
The appointment of Sukumar, the
former chief training officer at German
airline Deutsche Lufthansa AG, has
been controversial and the
government has appointed a two- member committee to review his
appointment.

Country ’s first seaplane Jal Hans takes wings

New Delhi: Civil Aviation Minister
Praful Patel launched Jal Hans, the first
seaplane of Pawan Hans Helicopters
Limited, at a ceremony held in Mumbai
today.
Seaplanes would also be introduced in other areas of India like
Lakshadweep, Goa, Orissa. Seaplane, a
fixed-wing aircraft capable of taking
off and landing on water, is ideal
when island is far from land or when
there is no landing strip. Unlike regular aircraft, these do not require a large
runway.
This is the first time that seaplane
operations have been introduced in
India. Jal Hans is a Cessna Caravan
208. A Amphibian fitted with modern navigation features of any large jet.
With a seating capacity of 10, of which
eight are passenger seats, it can travel
up to 250 km in about an hour and
land on most calm waters. It can also
land on ground using the wheels configuration.
The first seaplane service will be
operationalised in the Andaman and
Nicobar Islands. It will connect Port
Blair with Havelock and subsequently
other islands in north Andaman. At Port Blair, it will operate from the
airport, at Havelock and Diglipur, it will
operate from a waterdromme.

DGCA to no longer probe accidents

Mumbai: Finally, India will have an
independent process to investigate air
accidents and serious incidents with
the Civil Aviation Ministry forming a
Committee of Investigations in January
next year. The formation of an independent
body would, among other things,
mean the DGCA would also come
under the scanner during probe for its
policies and decisions that may have
played a part in an air crash or incident.
'The Committee will be headed by a
director and four other officers. With a
pool of independent experts from the
aviation industry, the Committee
would have 15-20 members," said civil aviation secretary Dr Nasim Zaidi.
Currently, DGCA officials conduct
probe into most of the accidents. "The
same authority cannot be the
prosecutor, investigator and the
judge," said Zaidi, referring to the need to keep the DGCA away from probe
into accidents.
In case of accidents involving major
loss of life, like the Mangalore aircrash,
an independent Court of Inquiry was
formed for the probe. "If a Court of Inquiry is needed to be formed, the
committee of investigations will co-
ordinate in the matter," said Zaidi. The
ministry's approval for the formation
of the Committee is pending.
Meanwhile, DGCA officials will continue to investigate incidents that are not
serious in nature.

How the Turn and Slip Indicator Works?

A simple version of a turn
indicator is a curved piece of
pipe with a ball in it. The
curve goes up. If the plane is
flying flat and level, gravity
pulls the ball to the bottom of the curve, indicating G-forces
and any turning forces are in
alignment and straight down
towards the bottom of the
plane. Now when you turn the
plane you have greater
turning forces effecting the
ball. if you turn properly,
tilting the wings in the
proper amount for the turn and giving just the right
amount of rudder, the ball
remains at the bottom of the
glass tube, in alignment with
the bottom of the plane.
