Early pilots navigated visually by looking for landmarks but as flying occurred at night and in poor weather, new navigation technologies were developed. In the 1920s, navigation aids helped pilots determine attitude and position even when the ground was not visible. In 1929, Sperry introduced the artificial horizon and other mechanical aids emerged in the 1930s. Today, aircraft are tracked by radar but GPS now allows pilots to determine their precise position without assistance from air traffic control. This has led to debates around who should control navigation - pilots using GPS or air traffic controllers.

To help ensure safe flights, air traffic controllers enforce a minim.pdfarihantpuneteleshope
To help ensure safe flights, air traffic controllers enforce a minimum time interval between
takeoffs. Explain why this time interval between takeoffs can be shortened if the wind has a
cross-runway component ( as opposed to blowing directly down the runway)?
Solution
Answer :
Use different types of air traffic pattern.
Procedures in the pattern[edit]
Aircraft are expected to join and leave the pattern, following the pattern already in use.
Sometimes this will be at the discretion of the pilot, while at other times the pilot will be directed
by air traffic control.
There are conventions for joining the pattern, used in different jurisdictions.
Similarly, there are conventions for departing the pattern.
There is also a procedure known as an \"orbit\", where an aircraft flies a 360° loop either
clockwise or anticlockwise. This is usually to allow greater separation with other traffic ahead in
the pattern. This can be the result of a controller\'s instruction. If at the pilot\'s initiative, the pilot
will report e.g. \"(tail number or flight number) making one left-hand orbit, will advise
complete\".
To practice take off and landing, a pilot would often fly many patterns, one after another, from
the same runway. Upon each landing, depending on the runway distance remaining, aircraft and
pilot capabilities, noise abatement procedures in effect, and air traffic control clearance, the pilot
will perform either a full stop landing (taxi to the runway beginning for subsequent take-off), a
touch-and-go (stabilize in the landing roll, reconfigure the aircraft for take-off, and take-off
without ever stopping the aircraft), or a stop-and-go (decelerate to a stop, then take-off from the
remaining runway). In the U.S., when operating in a controlled airport a pilot can be cleared for
the option, allowing any of the landing options above, or a rejected landing, at pilot\'s discretion.
Time interval importance in radar system.
Radar coverage
Since centers control a large airspace area, they will typically use long range radar that has the
capability, at higher altitudes, to see aircraft within 200 nautical miles (370 km) of the radar
antenna. They may also use TRACON radar data to control when it provides a better \"picture\"
of the traffic or when it can fill in a portion of the area not covered by the long range radar.
In the U.S. system, at higher altitudes, over 90% of the U.S. airspace is covered by radar and
often by multiple radar systems; however, coverage may be inconsistent at lower altitudes used
by unpressurized aircraft due to high terrain or distance from radar facilities. A center may
require numerous radar systems to cover the airspace assigned to them, and may also rely on
pilot position reports from aircraft flying below the floor of radar coverage. This results in a
large amount of data being available to the controller. To address this, automation systems have
been designed that consolidate the radar data for the controller. This consolid.

UAV(unmanned aerial vehicle) and its application Joy Karmakar
This document discusses unmanned aerial vehicles (UAVs), including their definition, history, components, applications, and disadvantages. UAVs are aircraft without human pilots that can be controlled autonomously or remotely. They have various applications both militarily and civilly, such as aerial surveillance, search and rescue operations, agriculture, filmmaking, and more. The key components of UAVs are the payload, air vehicle, navigation systems, and communications systems. India has developed several UAVs domestically such as Rustom, Nishant, and Lakshya for military purposes. The future of UAV technology remains dynamic with new discoveries expected over the next 16 years.

4. In this paper we present an algorithm for the
autonomous navigation of an unmanned aerial
vehicle (UAV) following a moving target.
It gives applicable method for the tracking of ground
vehicles by aerial vehicles.
It depends on the capability to follow waypoint
commands. Sensing of ground vehicle position with
significant time delays is assumed.
The delays model the time of image processing, and
the communication delays involved in sending data to
a ground station, performing the computations and
receiving the results on the UAV.
5. The UAV is an acronym for Unmanned Aerial
Vehicle, which is an aircraft with no pilot on
board.
UAVs can be remote controlled aircraft .(e.g.
flown by a pilot at a ground control station) or can
fly autonomously based on pre-programmed flight
plans or more complex dynamic automation
systems.
8. Path planning
Cameras, Horizon air framework, Image
processing technique, object recognition algorithm
Sensing
Vision based system with downward looking
camera
Filtering
Kalman filter
12. Colour based vision
tracking is used.
Camera attached to the
airframe of UAV,
pointing downwards,
IMU & Barometer
Data is transmitted
between UAV & GCS
through radio
transmission
GCS done computation
13. Pan-tilt camera, PWM
servo driven, 2-axis
(pitch-yaw) controller
with gimbal position
feedback sensor for plane
orientation tracking
Sensor stabilized with
flight software using IMU
feed forward technique
for target tracking
Target coordinates
computed in ECEF
14. Remote sensing
Commercial aerial surveillance
Domestic policing
Oil, gas and mineral exploration and production
Transport
Scientific research
Armed attacks
Civilian casualties
Search and rescue
Conservation
Forest fire detection
Archaeology
Future potential
15. Does not contain, or need, a qualified pilot on board
Can enter environments that are dangerous to human
life
Reduces the exposure risk of the aircraft operator
Can stay in the air for up to 30 hrs
Can be programmed to complete the mission
autonomously even when contact with it’s GCS is lost
Safer environment
Even if plane crash, pilot still safe.
UAVs can go faster
16. Very expensive to produce and keep up
Human mistake in remote controls can cause plane to
crash
Computer systems or software could break down
resulting in loss of plane and casualities on ground.
In adverse weather such as rain, snow, ice, frost or fog
UAV can not be launched or land or perform its
function.
Often mechanical failures
17. UAV follows lateral guidance law for autonomous
target following.
A full vision-based tracking , a color-based
tracking, GPS tracking, Image processing
techniques, Object recognition algorithm, Real
time vision algorithm etc. are followed by UAV
for autonomous target following.
