What’s a landing?
A landing is the successful transition of
an aircraft from flying … to a stop on the
surface where the pilot intended.

What’s a good landing?
• Helpful definitions:
• If you can walk away, it’s a good landing.
• If you can reuse the airplane, it’s a great landing.
• Alternate definition:
• Airplane on ground. Crew alive. Mission success.

Why am I here?
• Reduce the number of landing
accidents, and
• Reduce the number of fatalities
• Exchange ideas
• Improve teaching

Landings Number Four on the NTSB List
• Landings are 30.3% of Accidents
. . . and are 4.7% of Fatal Accidents
compared to
• Climb phase accidents are 2.9% of Total
. . . and are 4.7% of Fatal Accidents

How dangerous is landing?
Year 2009 per 2010 Nall report:
• 348 landing accidents
• Only 6 were fatal.
• TOO MANY FATALITIES!!!
• TOO MANY ACCIDENTS!!!

Why fatalities? -- NTSB
Year 2006 per NTSB 2010 report:
• Botched crosswind approach, hit tree on goaround at approach end
• Bounce, PIO, VMC roll on go-around (multiengine)
• Botched water landing (seaplane)
• Wheels-down water landing (seaplane)
• Broken crankshaft, off-field

Which is more important,
long life or check ride?
• Saving lives should be our first concern.
• It’s more important to teach safety than to
prepare for the check ride.
• Do we agree?

Forum Priorities
• Primarily, we’ll talk about preventing landing
accidents.
• How to teach the necessary skills so they
won’t be forgotten.
• Afterwards, we can talk about making
beautiful landings.

If landing is safe,
what is dangerous?
• A badly executed approach
• A botched go-around
• In 2008 one fatal undershoot
• In 2008 three fatal overshoots
Downloaded from www.avhf.com
Two elements of landing
• Directional Control
• Energy Management
Downloaded from www.avhf.com
What are the results of bad
Directional Control?
• Directional Control problems lead to bent
airplanes and bruised egos, but generally,
not to fatalities.
• We’ll return to this topic
Downloaded from www.avhf.com
What is energy management?
• Use of
• Throttle
• Elevator
• To get the aircraft down to runway
• At the right place
• At the right speed
Downloaded from www.avhf.com
What are the principles of energy
management?
• Landing will not occur if the airplane is
going too fast.
• Arrival will be rough if the airplane is
going too slow.
• Damage is related to kinetic energy.
Downloaded from www.avhf.com
What is a Stabilized Approach?
• “ . . . a constant angle glidepath towards a
predetermined point on the landing runway.”
What does it look like?
• “. . . during a stabilized approach the
apparent runway shape does not change.”
Reference Airplane Flying Handbook page 8-8.
Downloaded from www.avhf.com
Where should you aim?
• Aim 1/6 of the way down the runway
• The descent angle should be controlled
throughout the approach so that the
airplane will land in the center of the first
third of the runway.
Downloaded from www.avhf.com
What is the right approach speed?
• What the manufacturer suggests
• Or in its absence, 1.3 x VSO
Downloaded from www.avhf.com
What is the right approach speed in
gusty conditions?
• What the manufacturer suggests
• Or in its absence
• 1.3 x stall speed plus
• Half the gust factor
Downloaded from www.avhf.com
Do you agree?
If you fly a stabilized approach at the right
speed, you are unlikely to hurt yourself.

What do bounces and PIO
have in common?
• Are they the result of a preoccupation
with landing?
• … rather than maintaining a landing
attitude at the runway ?

Secrets to the Perfect Landing
• There are three secrets to a perfect
landing.
• Unfortunately, no one knows what they
are.

How many crosswind approach
techniques are there?
The Airplane Flying Handbook describes two:
• Wing-low (sideslip) method
• Crab method
Which do you teach? Why?
Downloaded from www.avhf.com
How many crosswind touchdown
techniques are there?
The Airplane Flying Handbook describes
one:
Wing-low (sideslip)
Even if using a crab, the approach must be
converted to wing-low before touchdown.

What about special situations?
• When, if ever, do you retract flaps on a
short-field landing?
• What is different in an engine-out
situation?
Downloaded from www.avhf.com
What about particular airplanes?
• What is different about retractable
landing gear?
• Do we need to talk about conventional
gear?
• Any ski plane instructors here?
• Any seaplane instructors here?
Downloaded from www.avhf.com
Any closing advice?
• Every takeoff is optional; landings are
mandatory.
• NOT SO.
• Every landing is optional, unless you are on
fire or out of gas.
• If in doubt, GO AROUND.
