Emergency Landing Spots
How
Pilots Choose an Emergency Landing Spot in an Airplane
BY SARINA
HOUSTON
During flight
training, student pilots spend many hours practicing emergency or
"off-field" landings so they'll be prepared in the event they have to
perform one in real life.
There are several
reasons why pilots might have to put an airplane down in a field, on a road, or
somewhere else outside of an airport.
Engine failure due to
fuel starvation is probably the most common reason, but an off-field landing
can be the result of structural failure, an engine or cockpit fire, a bird
strike, or any of a number of other emergency situations.
Choosing a place to
land in an emergency can be difficult, and pilots may have to take many factors
into consideration, including automobile traffic on the ground, surrounding
terrain and obstacles, wind direction and speed, the plane's altitude, and the
glide distance of the aircraft (the distance the plane can travel without
engines).
The two best options
are usually a field or a road, with other possibilities generally proving more
hazardous to the plane's passengers and crew and to people on the ground.
Fields
Fields are usually very
good options for forced landings. They're wide open, empty, and unpopulated.
They're often flat
and free of obstacles and offer plenty of space for a long landing if the pilot
overshoots.
But pilots must be
cautious even in fields. They can have hidden obstacles like fence posts and
irrigation lines.
And depending on
what's growing, the pilot may be in for a bumpy landing. A cornfield, for
example, might actually destroy an airplane, while a mowed hayfield might
cushion the landing.
And a freshly tilled
field might look inviting to a pilot, but if it's wet enough, it will probably
cause the airplane to sink into the mud and then cartwheel.
Roads
Roads can be good
landing sites, but only if there are no cars or pedestrians on them.
Pilots should always choose
a field over a road if there are cars or the possibility of cars on the road
because they're responsible for not becoming a hazard to people on the ground.
A paved or a dirt
road that's not in use is an obvious choice for an off-field landing.
But as with any other
landing site, pilots need to be on the lookout for obstacles like fence posts
and power lines that may not be visible until they're very close.
Other Landing Areas
Besides a field or a
road, there are a few other suitable landing areas that might help minimize the
destruction of the plane and save lives.
Pilots might look for
beaches, dried lake beds, shorelines, dirt patches, or any other type of flat
terrain.
A beach is a fine
option for pilots as long as there aren't any people around.
The sound of the
waves could mask the noise of the engine — if it's working — and people might
not see the plane coming.
Pilots should avoid
hilly or rocky terrain if at all possible. A level surface is crucial for
landing.
When There Is Nowhere
to Go
If pilots have no
good landing spots in sight, they shouldn't panic. Many pilots have landed
aircraft on top of trees or in water and lived to talk about it.
If a pilot is over a
forested area and a tree landing is inevitable, they should prepare the
aircraft for an emergency landing and concentrate on making the approach as
slow and as stable as possible.
A slow approach near
stall speed with minimal descent rate and minimal forward speed will increase
their chances of survival and minimize wreckage.
Ditching on water
might be one of the most challenging of all of the potential emergency
scenarios.
A water landing
requires a bit more finesse in order to not cartwheel or flip over.
With too much speed
or in an uncontrolled state, a water impact can be like hitting a wall.
But a nice controlled
landing might mean passengers and crew will survive, as long as they can swim
to shore or have a life vest and the water isn't too cold.
In all cases, the most important thing
for pilots to do is to continue to fly the plane.
No matter where they are, a controlled
approach and landing is better than a crash and subsequent fire.
