a go-around is recognized, the safer the go-around/

rejected landing will be. The go-around maneuver is not

inherently dangerous in itself. It becomes dangerous

only when delayed unduly or executed improperly.

Delay in initiating the go-around normally stems from

two sources: (1) landing expectancy, or set—the an -

ticipatory belief that conditions are not as threatening

as they are and that the approach will surely be termi-

nated with a safe landing, and (2) pride—the mistaken

belief that the act of going around is an admission of

failure—failure to execute the approach properly. The

improper execution of the go-around maneuver stems

from a lack of familiarity with the three cardinal prin-

ciples of the procedure: power, power, and power.

Power is your first concern. The instant you decide to

go around, full power must be applied smoothly and

without hesitation, and held until the powered para -

chute climbs back to pattern altitude. Applying only

partial power in a go-around is never appropriate. You

must be aware of the degree of inertia that must be

overcome, before a powered parachute that is settling

towards the ground can become capable of turning

safely or climbing. The application of power should

be smooth as well as positive. Abrupt movements of

the throttle in some powered parachutes will cause the

engine to falter.

Common errors in the performance of go-arounds (re-

jected landings) are:

• Failure to recognize a condition that warrants a

rejected landing.

• Indecision.

• Delay in initiating a go-around.

• Failure to apply maximum allowable power in a

timely manner.

• Abrupt power application.

• Failure to adequately compensate for torque/

P-factor.

Turbulent Air Approach and Landing

Powered parachute flying is a low-wind sport. It is im-

portant PPC pilots evaluate the upper-air winds to en-

sure the wind is within the limitations for that aircraft,

accounting for wind shear and wind gust possibilities

at pattern altitude.

For flying in more turbulent air on final approach,

maintain power throughout the approach to reduce

your descent rate in case you do experience a down

gust. This will alleviate the possibility of an excessive

descent rate.

Emergency Approaches and

Landings (Simulated)

From time to time on dual flights, the instructor should

give simulated emergency landings by retarding the

throttle and calling “simulated emergency landing.”

The objective of these simulated emergency landings

is to develop the pilot’s accuracy, judgment, planning,

procedures, and confidence when little or no power is

available.

A simulated emergency landing may be given at any

time. When the instructor calls “simulated emergency

landing,” the pilot should consider the many variables,

such as altitude, obstruction, wind direction, landing

direction, landing surface and gradient, and landing

distance requirements. Risk management must be ex-

ercised to determine the best outcome for the given

set of circumstances. The higher the altitude, the more

time the pilot has to make the decision of where to

land.

Using any combination of normal gliding maneuvers,

from wing level to turns, the pilot should eventually

arrive at the normal key position at a normal traffic

pattern altitude for the selected landing area. From

this point on, the approach will be as nearly as pos -

sible a normal power-off approach. [Figure 11-9]

All pilots should learn to determine the wind direction

and estimate its speed. This can be done by observing

the windsock at the airport, smoke from factories or

houses, dust, brush fires, and windmills.

Once a field has been selected, the student pilot should

always be required to indicate it to the instructor. Nor-

mally, the student should be required to plan and fly

a pattern for landing on the field elected until the in -

structor terminates the simulated emergency landing.

This will give the instructor an opportunity to explain

and correct any errors; it will also give the student an

opportunity to see the results of the errors.

However, if the student realizes during the approach

that a poor field has been selected—one that would

obviously result in disaster if a landing were to be

made—and there is a more advantageous field within

gliding distance, a change to the better field should

be permitted. The hazards involved in these last-min-

ute decisions, such as excessive maneuvering at very

low altitudes, should be thoroughly explained by the

instructor.

During all simulated emergency landings, the engine

should be kept warm and cleared. During a simulated

emergency landing, either the instructor or the student

should have complete control of the throttle. There

should be no doubt as to who has control since many

near accidents have occurred from such misunder -

standings.

Every simulated emergency landing approach should

be terminated as soon as it can be determined whether

a safe landing could have been made. In no circum -

stances should you violate the altitude restrictions

detailed in 14 CFR part 91 or any local nonaviation

regulations in force. It is also important to be courte -

ous to anyone on the ground. In no case should it be

continued to a point where it creates a hazard or an

annoyance to persons or property on the ground.

In addition to flying the powered parachute from the

point of simulated engine failure to where a reason -

able safe landing could be made, the pilot should also

learn certain emergency cockpit procedures. The habit

of performing these cockpit procedures should be de-

veloped to such an extent that, when an engine failure

actually occurs, the pilot will check the critical items

that would be necessary to get the engine operating

again after selecting a field and planning an approach.

Accomplishing emergency procedures and executing

the approach may be difficult for the pilot during the

early training in emergency landings.

There are definite steps and procedures to follow in a

simulated emergency landing. They should be learned

thoroughly by the student, and each step called out

to the instructor. The use of a checklist is strongly

recommended. Most powered parachute manufac -

turers provide a checklist of the appropriate items.

[Figure 11-10]

Critical items to be checked should include the quan-

tity of fuel in the tank and the position of the ignition

switches. Many actual emergency landings could have

been prevented if the pilots had developed the habit of

checking these critical items during flight training to

the extent that it carried over into later flying.

Instruction in emergency procedures should not be

limited to simulated emergency landings caused by

power failures. Other emergencies associated with

the operation of the powered parachute should be ex-

that the descent does not result in an excessively high

sink rate. If a high sink rate is continued close to the

surface, it may be difficult to slow to a proper rate

prior to ground contact. Any sink rate in excess of

800 –1,000 feet per minute is considered excessive. A

go-around should be initiated if the sink rate becomes

excessive.

Use of Power

Power can be used effectively during the approach

and roundout to compensate for errors in judgment.

Power can be added to slow the descent rate to an ac-

ceptable rate. Some pilots use power rather than wing

flare to land smoothly. After the powered parachute

has touched down, it will be necessary to close the

throttle so the additional thrust and lift will be re -

moved and the powered parachute will stay on the

ground.

High Roundout

It is possible to flare for landing too high above the

ground. [Figure 11-13] If this happens, efforts need to

be made to prevent the wing from surging forward. The

power should not be reduced and the flare should only

be reduced slightly or the wing could surge forward

as the pendulum starts swinging back. Some pilots try

to correct this situation by reducing the throttle too

much and letting off the flare completely in order to

land closer to their chosen landing point. This invari-

ably results in the cart rotating back under the forward

surging wing and diving towards the ground because

lift has been dramatically reduced. Any surging for -

ward of the wing above the cart should be slowed by

increased flare. If the flare is performed too high off

the ground, a go-around can be accomplished.

It is recommended that a go-around be executed any

time it appears that there may not be enough runway

to safely land the powered parachute or if the landing

is in any other way uncertain.

Bouncing During Touchdown

When the powered parachute contacts the ground

with a sharp impact as the result of an excessive sink

rate, the cart tends to bounce back into the air.

The corrective action for a bounce when it is very

slight is to make a follow-up landing by applying suf-

ficient power to cushion the subsequent touchdown

and by adding flare as needed.

When a bounce is severe, the safest procedure is to

EXECUTE A GO-AROUND IMMEDIATELY . No

attempt to salvage the landing should be made. Ap -

o Look for a suitable landing area

considering terrain/obstacles/wind.

o Maintain control of the aircraft.

plained, demonstrated, and practiced if practicable.

Among these emergencies are such occurrences as fire

in flight, electrical system malfunctions, unexpected

severe weather conditions, engine overheating, immi-

nent fuel exhaustion, and the emergency operation of

powered parachute systems and equipment.

Faulty Approaches and Landings

Low Final Approach

When the base leg is too low, insufficient power is

used or the velocity of the wind is misjudged, suf -

ficient altitude may be lost, which will cause the

powered parachute to be well below the proper final

approach path. In such a situation, you would have

to apply considerable power to fly the powered para -

chute (at an excessively low altitude) up to the run -

way threshold.

When it is realized the runway will not be reached

unless appropriate action is taken, power must be

applied immediately to stop the descent. When the

proper approach path has been intercepted, the cor -

rect approach attitude should be re-established and

the power reduced and a stabilized approach main -

tained. [Figure 11-11] If there is any doubt about the

approach being safely completed, it is advisable to

EXECUTE AN IMMEDIATE GO-AROUND.

High Final Approach

When the final approach is too high, reduce power as

required. [Figure 11-12] When the proper approach

path has been intercepted, adjust the power as re -

quired to maintain a stabilized approach. When steep-

ening the approach path, however, care must be taken

ply full power and check the wing is LOC (lines free,

cells open, wing centered) since a hard landing can

collapse a ram-air wing. It would be extremely fool -

ish to attempt a landing from a bad bounce since the

skill set that would allow a student to make a severe

bounce would not be up to the task of salvaging a bad

landing.

Hard Landing

When the powered parachute contacts the ground dur-

ing landings, its vertical speed is instantly reduced to

zero. Unless provisions are made to slow this vertical

speed and cushion the impact of touchdown, the force

of contact with the ground may be so great it could

cause structural damage to the powered parachute.

Reductions in rapid descent rates are made through

throttle increases. Closer to the ground, additional

flare is applied before touchdown.

The purpose of pneumatic tires, shock absorbing land-

ing gears, and other devices is to cushion the impact

and to increase the time in which the powered para -

chute’s vertical descent is stopped. Within a fraction

of a second, the powered parachute must be slowed

from a high rate of vertical descent to zero, without

damage.

During this time, the landing gear together with

some aid from the lift of the ram-air wing must sup -

ply whatever force is needed to counteract the force

of the powered parachute’s inertia and weight. The

lift decreases rapidly as the powered parachute’s for-

ward speed is decreased, and the force on the landing

gear increases by the impact of touchdown. When the

descent stops, the lift will be zero, leaving the land -

ing gear alone to carry both the powered parachute’s

weight and inertia force. Any time you have a hard

landing, inspect your landing gear, tires, and structure

to make sure there is no structural damage.

Wing Blowing Over After Touchdown

When landing in a crosswind, there is a concern that

the wing will blow downwind during the after-land -

ing roll. This is due to the fact that the wing is flexibly

attached to the cart.

Anytime a powered parachute is rolling on the ground

in a crosswind condition, the upwind side of the para-

chute is receiving a force that wants to push it down-

wind.

If no correction is applied, it is possible that the upwind

side of the parachute will rise sufficiently to cause the

downwind side of the parachute to strike the ground.

If the wind and/or the forward motion of the powered

parachute is great enough, a rollover may result. It is

important for a pilot to remember that the parachute

should be flown or pulled to the ground right after

landing the cart. The cart and the parachute’s move -

ments should be controlled together on the ground.

Night Operations and the

Powered Parachute

Flying a powered parachute after sunset requires a

private pilot powered parachute certificate. In addi -

tion, the powered parachute needs to be equipped for

night operations by adding position lights for taxi and

flight. Position lights are green on the right, red on

the left, and white in the back. Anti-collision strobe

lights can also be used in addition to position lights.

[Figure 12-1]

the lines are not tangled (LOC). The takeoff area needs

adequate illumination to ensure hazards are avoided.

Typically, lights on poles can present a hazard at an

airfield.

A powered parachute flight where the preflight in -

spection was completed during daylight, just prior to

sunset, and then the final landing made after sunset

may be a more feasible endeavor. If a powered para -

chute pilot holding a private pilot certificate or higher

were to venture into night flight, Chapter 15 of the

Pilot’s Handbook of Aeronautical Knowledge should

be carefully reviewed to understand the parameters

that need to be considered prior to conducting a flight

in the dark.

Emergency Situations

This section contains information on dealing with un-

expected situations that may occur in flight. The key

to successful management of an emergency situation,

and/or preventing a problem from progressing into a

true emergency, is a thorough familiarity with, and ad-

herence to, the procedures developed by the powered

parachute (PPC) manufacturer. Hence, the following

guidelines are generic and are not meant to replace

the manufacturer’s recommended procedures. Rather,

they are meant to enhance your general knowledge

in the area of emergency operations. If any of the

guidance in this chapter conflicts in any way with the

manufacturer’s recommended procedures, the manu -

facturer’s recommended procedures take precedence.

Review the lost procedures and flight diversion tech-

niques in Chapter 14 of the Pilot’ s Handbook of Aero-

nautical Knowledge. You must be able to select an

appropriate alternate airport or landing area and route,

determine there is sufficient fuel to fly to the alternate

airport or landing area, turn to and establish a course

to the select alternate destination, and maintain the

appropriate altitude and heading while doing so. As

a PPC pilot you must be able to select an appropriate

course of action if you become lost, including main -

taining an appropriate heading and climb if necessary,

Figure 12-1. Powered parachutes must be specifically

equipped for night flight.

The use of lighted runways for night flight imposes

several problems for the powered parachute pilot.

Setting up on a runway and conducting a preflight on

a powered parachute cart and wing in the dark could

tie up a designated runway area for a considerable

amount of time, not to mention raise issues about be-

ing able to see the aircraft and wing components for

proper preflight inspection.

A pilot planning to fly a powered parachute at night

should ensure adequate illumination is provided for

takeoff. The wing needs to be illuminated to ensure

the wing cells are all open, the wing is centered, and

identify prominent landmarks, and use your naviga -

tion system (GPS) or contact an ATC facility for as -

sistance, as appropriate.

Review the POH for the aircraft you fly to be familiar

with the necessary pilot actions required for system

and equipment malfunctions. You must be prepared

to analyze the situation and take action if you experi-

ence any of the following system and equipment mal-

functions: engine/oil and fuel, electrical, carburetor or

induction icing, smoke and/or fire, flight control/trim,

pitot static/vacuum and associated flight instruments,

propeller, ballistic recovery system malfunction (if

applicable), or any other emergency unique to the

powered parachute you are flying.

Accidents

It is estimated that 85 percent of accidents occur dur-

ing the takeoff process, 10 percent transpire during

landings, and 5 percent happen in flight. The vast

majority of these accidents are the direct result of

complacency. The cause of this complacency is that

the PPC is relatively easy to fly. Hence, if you find

complacency setting in, you need to turn from outside

distractions, and direct your attention to the immedi -

ate situational awareness of the aircraft.

The following are some reasons for PPC complacency

during flight:

• The PPC does not require quick reactions.

• When compared to other light-sport aircraft

(LSA), the PPC flies very slowly.

• The PPC has only two axes around which you

can directly control (lateral-pitch and vertical-

yaw). Note: As there are no ailerons on a PPC,

roll or movement around the longitudinal axis

cannot be directly controlled. However, there

is longitudinal roll invoked during a steep turn

as the centrifugal force of the cart directs the

cart to the outside of the suspension point of the

wing.

• The controls are very intuitive (push right to go

right, left to go left, more throttle to go up, and

less to go down).

It is possible the outside environment can become a

distraction to the necessary situational awareness of

flying (i.e., situational complacency). Hence, in-flight

accidents can be due to the pilot’s failure to see ob -

structions (power lines and tower cables) and to an -

ticipate weather-related turbulence and its resultant

negative effects on a PPC’s light wing (i.e., wind

rotors or mechanical turbulence). Landing accidents

are usually the result of porpoising (too rapid throttle

movements), thermals, or unsafe field terrain. Takeoff

problems can be caused by: (1) failure to get a wing

LOC before adding airborne power; and (2) failure to

take off into the wind.

Potential Hazards of the

Standing PPC

Even while parked on the ground, high winds can pick

up the wing of an unsecured powered parachute and

begin carrying it away. To regain control of a free-

standing PPC with a semi-inflated, dragging wing,

rescuers need to grasp the steering lines —not the

cart! Then with a steering line in hand, pull the line

back toward the front of the cart (into the wind) and

tie it off to any structured part of the PPC. This will

keep the wing from gathering air and re-inflating. If

you are by yourself, you do not have to do both lines

simultaneously. It would be best to get both lines, but

with a PPC that is dragging down the field, grab any

steering line and get at least one line secured; then

secure the second line. When you pull a steering line,

the canopy will be pulled down on that side and the

air in the wing will literally be pulled out, as the wing

is hauled back and down.

The best safety procedure is prevention. To safeguard

a PPC from high winds, immediately after landing,

secure the wing. Even if you only intend to refuel, it is

highly recommended to condense the exposure of the

wing to the elements: the harmful ultraviolet rays of

the sun and those unexpected wind gusts. As soon as

possible after landing, condense the wing by folding it

on top of itself and put something on top of it to secure

it. It is best to pack the canopy to keep it out of the sun

and make sure the wind cannot inflate the wing and

if possible, lean the nose wheel up, then place the fan

guard of the cart back and down on the folded wing.

Securing it this way will usually be adequate for short

breaks when the make and model allows for this static

positioning. [Figure 12-2]
