5. Introduction ….
The unique feature of air travel is the fact that men, goods and mail can move quickly from
any point of the global air network to any other by any combination of routes, on a single
ticket valid everywhere. This is the result of a massive system of bilateral agreements between
governments, pains-taking arrived at since the end of world War II.
Life is becoming more and more busy People want to save time in every way.
There is no way out for such persons other than the aero plane . There is no
obstacle in air travel as we find on roads. Air-travel is most comfortable.
The tremendous and continuous progress made in recent years in speed, safety, passenger-
comfort and convenience, is bound to make more and more people air minded. Air travel has
brought with it new philosophies. Scientific progress is bringing about changes in he outlook
of men. All these changes are certain to make the aero plane more popular. The future of air-
travel, in India and in other counties, is bright.

8. Research Proposal and Hypothesis
Related Questions :
o What is an Emergency landing?
o What are the different types of emergency landing?
o What are the causes for an emergency landing?
o How to overcome emergency landings?
Hypothesis
o With proper training and planning , they can be made without serious injuries .
9. Justification
• Despite in common, emergency landings are a rare phenomena in the aviation
industry. An emergency landing can happen as a result of several factors, which could
be caused by latent and or active failures.
I. Latent failure is described as a failure caused by the planning system, such as
airline management or maintenance procedures.
II. Active failures could also described as pilot or operator error; these are the
errors directly caused by the system or equipment operator, such as pressing the
wrong button and these are the main classifications of an emergency landing
and that’s why I chose the topic
“Will the Aircraft Overcome Emergency Landing “.

15. What is an Emergency Landing ?
An ” Emergency Landing ”is a landing made by an aircraft in response to a crisis
which either interferes with the operation of the aircraft or involves sudden
medical emergencies necessitating diversion to the nearest airport .
OR
An unscheduled airplane landing that is made under circumstances (engine failure
or adverse weather) not under the pilot's control.
16. What are the different types of emergency landing?
• Despite common portrayal in the movies, emergency landings are a rare
phenomena in the aviation industry. An emergency landing can happen as a result
of several factors, which could be caused by latent and or active failures.
(i) Latent failure is described as a failure caused by the
planning system, such as airline management or maintenance procedures.
(ii) Active failures could also described as pilot or operator
error; these are the errors directly caused by the system or equipment operator,
such as pressing the wrong button.
There are several different types of emergency landings for powered aircraft:
A, Planned landing
B, Unplanned landing
17. A , Wheels-Up Landing (Belly Landing)
When a plane lands with the wheels up/retracted, using the belly of the aircraft
instead. Some factors that may contribute to a belly landing are mechanical failure (the
gear can not be pulled out) or pilot error (forgot to pull out the landing gear) . In other
instances, such as during a water landing or landing off a prepared surface due to
engine failure, fuel starvation etc. a pilot may elect to land with the wheels up. On a
rough surface or water landing, the aircrafts belly may act as a skid for the landing,
whereas in these situations having the wheels down may cause the aircraft to 'dig in'
or flip over.
18. B, Water Landing (also known as Ditching)
One option for the pilot of an aircraft experiencing engine failure(s),
fuel starvation or exhaustion, or other emergencies which require the aircraft to be landed
immediately, is a water landing. Water landings may offer a flatter, obstacle free surface
that will allow the aircraft to decelerate more slowly than land based emergency landing.
An aircraft landed successfully on the water will often
remain afloat for some time due to design and the buoyancy provided by fuel tanks etc.
Pilots receive briefings and simulator training (in the airline environment) on how to carry
out water landings. Many such landings are survivable, but the continued success of a safe
landing is dependant on the post-accident actions, such as use of floatation devices
(correctly- inflate AFTER or as leaving the aircraft) and rescue.
19. C , Hard Landing
A hard landing is not specifically an emergency, although it may result from an
emergency situation. A hard landing happens when a plane uses steep descent on final
approach to touchdown. In some cases, the plane may bounce back into the air before it
finally lands on the runway.
“Aviation Glossary (2009)” defines the terms as "an event
during landing that results in excessive G-forces being transmitted into the structure of
the aircraft". A hard landing may have one or more of several potential outcomes: pilot
embarrassment, a heavy landing engineering inspection, burst tyre, structural damage or
even structural failure of the aircraft resulting in an insurance write-off or catastrophic
destruction.
20. D, Dead - Stick Landing
A dead-stick landing occurs "when an aircraft loses all of its propulsive power and is forced to
land" Although this situation is generally categorized under emergency landing for most
aircraft, some gliders and display pilots carry out dead-stick landings as their normal landing
technique. This type of landing is rarely experienced by commercial aircraft and if it does
occur it is classified as an emergency landing.
With helicopters , a forced landing involves autorotation, since the
helicopter glides by allowing its rotor to spin freely during the descent thus generating lift.
When a pilot makes an emergency landing of an aircraft that has some or all of its propulsive
power still available, it is known as a precautionary landing.
21. An example of such a DEAD STICK LANDING occurred on April 29, 2007, at Manchester Airport in the United Kingdom ,
when a bird got sucked into the right engine of a Thomson fly Boeing 757 , flight Thomson 235H, just as it rotated off the
runway .
22. E, Crash Landing
A crash landing is one of the most dangerous type of landings, as the impact and
deceleration forces experienced in this landing are normally enormous. Pilots are not
generally trained to 'crash land' but a crash landing may occur when the pilot does not
have time, experience or the level of control required to achieve a better result.
Simulator and flight training are designed to teach the best procedures to avoid and
minimize the effects of an actual crash but when it comes to the real situation, the results
may not always meet the theoretical target.
23. F , Go-around/Missed Approach (Near-miss Landing)
A go-around is the description given to the act of aborting a landing attempt. When this
happens, pilots will often have another attempt at the approach and/or landing. There are
many situations where a missed approach is required, such as obstructed runway, too close
to the aircraft ahead, poor configuration (gear up, wrong flap, wrong speed), wind shear
etc.
Pilots are trained to monitor for these situations and are
expected to go-around if they occur. However, an approach may become dangerous when
the pilots do not realize one of these situations exist and they believe that the plane is still
on the right approach. The video below shows that the pilots did not realize that the flight
computer miscalculated the landing procedures.
24. G, Precautionary Landing
This type of landing is to prevent bad situations from becoming worse. During a
precautionary landing the pilot elects to land
away from the intended destination or an
otherwise prepared landing area. The pilot
will assess a location for suitability- surface,
length, slope, obstacles etc before carrying out
a landing. This type of landing is also part of
assessment when pilot applying for their licenses.
25. Precautionary Landing
The sooner a pilot locates and
inspects a potential landing site, the less the chance of additional
limitations being imposed by worsening aircraft conditions,
deteriorating weather, or other factors. This may be as a result
of problems with the aircraft, or a medical or police emergency.
26. Statistics
Not all phases of flight are equally prone to accidents. Most
accidents (55%) occur during landing or take-off. Only 10%
occur when the aircraft is en route.
27. What are the Causes of Emergency Landing?
Improper airspeed control
Poor judgment in the selection of an emergency landing area
Failure to estimate the approximate wind speed and direction
Failure to fly the most suitable pattern for existing situation.
Failure to accomplish the emergency checklist
Undershooting or overshooting selected emergency landing area
28. Other Emergencies can be :
Ice and snow
Medical Emergency
Terrorism
Low fuel
Bomb Scare
Lightening
Engine Failure .
29. Other Emergencies can be :
Bird Strike
Ground Damage
Volcanic Ash
Human Factors such as Pilot error
Piloting while intoxicated
Structural failure of the aircraft
Stalling
Fire
30. Other Emergencies can be :
Controlled flight into terrain
Electromagnetic Interference
Runway safety : it includes Runway excursion ,
Runway overrun , Runway incursion and Runway
confusion .
Deliberate air crew action
Military Action
31. How to overcome from these Emergencies?
Pre-flight safety demonstrations
Aircraft safety cards
Aircraft rescue and fire fighting
Proper , Planning
32. There are a wide range of factors that will affect survivability. This list is
non-inclusive and each variable is affected by many other variables:
• Airspeed
• Rate of descent
• Approach angle
• Aircraft attitude (nose position relative to forward motion, not how it's feeling that
day)
• Skid/slip angle (deviation from flying straight ahead)
• Aircraft design
• Aircraft configuration (flaps down, gear down)
• Existing airframe damage .
• The Pilot At the Controls (PAC) experience and skill
33. Summary
After doing the project I came into the conclusion that proper planning and taking
the right decision at the time of emergency can help the aircraft from an air accident.
It is not easy to execute in the air but tactfulness and skill of the pilot and crew
can compensate from an emergency .
Another factor is luck and faith in god are the essential factors for a work to be
successful .
35. What would be your future research if you get a
chance?
If I get a chance to do research once again ,
My future research would be based on the missing of Malaysian flight MH370
My Hypothesis would be :
“ Seventh Arc Theory behind Malaysian Airline MH370 ”
37. My Experience…
After the completion of this assignment, I came to know more
about the aircrafts , and the types of different emergencies
happen during a flight. And I can cross study what is
emergency landing ,different types of emergency landing and
how it occurs.
So, I can conclude that the assignment was a great learning
experience for me which will definitely help in future.
