Notices to Airmen ( NOTAMs) and Terminal Flight

Restrictions (TFRs), plan your flight (determine the

departure and destination airfield and route of flight),

file a flight plan (if planning to fly cross-country), and

head to your aircraft and point of departure. The pow-

ered parachute (PPC) may be stored in a hangar, ga -

rage, or covered trailer—any place out of the weather.

Begin with a visual inspection of the cart, then warm

up the engine. Push or taxi the PPC to the takeoff

point, shut down the engine, lay out and inspect the

wing. Finally, strap into the PPC, start the engine, kite

the wing, and then continue the takeoff roll to lift off.

[Figure 5-1]

Trailering

Trailers may be used to transport, store, and retrieve

powered parachutes. The PPC components should

fit snuggly without being forced, be guarded against

chafing, and be well secured within the trailer. Once

Get Ready to Fly

Your preflight preparations should include evaluating

the airworthiness of the:

• Pilot: experience, sleep, food and water, drugs/

medications, stress, illness

• Aircraft: fuel, weight (does not exceed

maximum), density altitude, takeoff and landing

requirements, equipment

• EnVironment: weather conditions and forecast

for departure and destination airfields and route

of flight, runway lengths

• External pressures: schedules, available

alternatives, purpose of flight

Often remembered as PA VE, it is important for you to

consider each of these factors and establish your own

personal minimums for flying.

Once you determine the PA VE factors are favorable

for flight, you should obtain a weather briefing, check

Figure 5-1. Typical sequence for a preflight inspection. Use the preflight checklist in your POH for every flight.

the loading is completed, take a short drive, stop, and

check for rubbing or chafing of components.

Prior to taking the trailer on the road, inspect the

tires for proper inflation and adequate tread; check

all lights to make sure they are operating; ensure the

hitch is free moving and well lubricated; make sure

the vehicle attachment is rated for the weight of the

trailer; check the vehicle and trailer brake operation.

When using a trailer, there are other precautions to

note. First, avoid towing with too much or too little

tongue weight as this causes the trailer to fishtail at

certain speeds, and it may become uncontrollable.

Second, take care when unloading the PPC to avoid

damage.

Where to Fly

The powered parachute can be transported by trailer

from one flying field to the next. For as many benefits

as this provides, transporting the powered parachute

into unfamiliar territory also includes some safety and

operational issues.

Make contact with the airport management to inquire

about any special arrangements that may need to be

made prior to departing from an unfamiliar airport.

Check the Airport/Facility Directory (A/FD) for traf-

fic pattern information, no fly zones surrounding the

airport, and special accommodations that may need

to be arranged.

Title 14 of the Code of Federal Regulations (14 CFR)

part 91 states that powered parachutes are to avoid

the flow of all other air traffic. In addition, you should

inform local pilots about some of the incidentals of

powered parachute flight (such as flying low and

slow); the more information that other category pi -

lots know about PPC flight characteristics, the more

they will understand the specific needs of the powered

parachute in flight. Sharing the same airspace with

various aircraft categories requires pilots to know and

understand the rules, and understand the flight charac-

teristics and performance limitations of the different

aircraft.

The ideal departure area for a powered parachute is an

open grassy area clear of debris and obstacles with a

groomed, even surface. Concrete and asphalt surfaces

should be avoided, as well as lit runways, as the struc-

tural integrity of the wing and suspension lines may

be compromised during takeoffs and landings if the

wing catches on the runway surface or surrounding

lighting.

Powered parachutes do not normally take off where

the rest of the airport traffic takes off. This is to help

both the PPC pilot and the pilots of other aircraft. A

powered parachute requires time to set up and depart;

it is not polite or safe to tie up an active runway while

this is being done. Exceptions to this would be the

edge of a very wide runway or an undeveloped area

next to the active runway where setup can take place

well away from the centerline of that active runway.

Another reason PPC pilots typically don’t use stan -

dard runways is that you want to set up into the wind

to avoid a crosswind takeoff. While slight crosswind

takeoffs are possible, they are usually unnecessary

due to the short-field capabilities of a powered para -

chute. You should do your best to point the machine

into the wind before you lay out the wing.

Extend consideration to land owners that may own a

flight strip in their field. You need permission to use

private property as an airstrip. Locate the area on an

aeronautical sectional chart to check for possible air -

space violations or unusual hazards that could arise

by not knowing the terrain or location. Avoid loitering

around residential structures and animal enclosures

because of the slow flight attributes of the powered

parachute and the distinct engine noise.

While selecting a takeoff position, make certain the

approach and takeoff paths are clear of other aircraft,

or will be clear by the time the equipment is set up.

Fences, power lines, trees, buildings, and other obsta-

cles should not be in the immediate flightpath unless

you are certain you will be able to safely take off and

clear them during takeoff and climbout.

Walk the entire length of the intended takeoff and

landing area prior to departure. Look for holes, mud-

dy spots, rocks, dips in the terrain, high grass, and

other objects that can cause the aircraft to be damaged

or the wing to snag during takeoff and landing. Physi-

cally mark areas of concern with paint, flags, or cones;

a pothole may not look like a pothole from the air.

There are a number of preflight actions you must

perform, mandated by 14 CFR part 91. You must be-

come familiar with all available information concern-

ing your flight, to include runway lengths at airport of

intended use, takeoff and landing distance accounting

for airport elevation and runway slope, aircraft gross

weight, wind, and temperature. For a flight not in the

vicinity of a conventional airport, this information

must include weather reports and forecasts, fuel re -

quirements, and alternatives available if the planned

flight cannot be completed.

Weather

The weather is a determining factor for all flight oper-

ations. Get a full weather briefing prior to your flight,

to include the current conditions and forecasts for

your departure and destination areas, and along the

route of flight. There are many sources for obtaining a

weather briefing, such as www.nws.noaa.gov, calling

1-800-WX-BRIEF, and a variety of internet sites that

specialize in local and regional weather. Crosswind

landings are possible in a powered parachute, but

crosswind takeoffs should be avoided. It is important

to review your departure procedure at your destina -

tion to ensure you don’t get into a field you cannot

depart from. In gathering your weather information,

know the wind conditions, temperature and dew point

spread, sky condition, and visibility. Review Chapters

10 and 11 in the Pilot’s Handbook of Aeronautical

Knowledge for a comprehensive understanding of

weather theory, reports, forecasts, and charts.

PPCs fly best in calm air. Check the wind forecast as

well as current conditions, as this information will de-

termine whether safe flight can be conducted. Winds

less than 10 miles per hour (MPH) are ideal; follow

the recommendations provided by the PPC manufac-

turer for the aircraft you will be flying. Steady winds

that are not gusting are more desirable, as the inflation

and overall performance of the wing is more predict-

able. For example, 5 MPH with no gusting is better

than 1 MPH gusting to 5 MPH. Some types of wings

perform differently in certain types of wind condi -

tions and pilotage skills—know your wing and your

abilities. Crosswind takeoffs in a powered parachute

are dangerous and should be avoided. If the runway

configuration does not allow for takeoff into the wind,

then the flight should be canceled or postponed from

that takeoff area. Do not attempt to take off in a cross-

wind with a powered parachute unless it is within the

pilot and aircraft capabilities, not a limitation in the

aircraft POH, and you have been trained thoroughly

for this advanced procedure. Crosswind landings are

possible in a powered parachute, but crosswind take-

offs should be avoided. It is important to review your

departure procedure at your destination to ensure you

don’t get into a field you cannot depart from.

Air temperature and humidity directly affect the per -

formance of the powered parachute wing and engine.

The powered parachute pilot who doesn’t understand

and respect the effect(s) density altitude has on any

given flight may get into situations that are not de -

sirable and could be hazardous. The higher the tem -

perature, humidity, and the actual altitude of the field

you are operating from, the greater the role density

altitude plays in determining how much runway the

powered parachute needs to get off the ground with

the load on board, and how much climb performance

the wing will have once airborne. The powered para-

chute may have cleared that obstacle at 8 a.m. when

the weather conditions were cooler with less humid -

ity, but at 1 p.m. with increased air temperature and

higher humidity levels the pilot will have to re-evalu-

ate the performance of that same aircraft. You need a

full understanding of density altitude to be a safe PPC

pilot; refer to Chapter 9 in the Pilot’s Handbook of

Aeronautical Knowledge.

Understand the different cloud formations and the

ground/air effects they can produce. [Figure 5-2] Cloud

clearance and visibility should be maintained for the

operations you intend to conduct (see Chapter 8 for

cloud clearance requirements in each class of airspace).

Knowledge of thermals and turbulence, and how to

determine where they can occur is also important.

[Figure 5-3]

Do not fly when ground and flight visibility is below

minimums for your pilot certificate and the class of

airspace where you will be operating (see Chapter 8).

Be particularly watchful for low visibilities when the

air and dewpoint temperatures are within a spread of

three or four degrees. The closer these temperatures

are to each other, the greater the chance for fog and

reduced visibility conditions.

In addition to adhering to the regulations and manu -

facturer recommendations for weather conditions, it’s

important for you to develop your own set of personal

minimums. These minimums will evolve as you gain

experience, and are also dependent on your recency

and currency in the make/model of aircraft you will

be flying.

Weight and Loading

Weight and loading must be considered before each

flight. Do not exceed the maximum gross weight as

specified in the POH. Always follow the POH perfor-

mance limitations.

The balance of the pilot, passenger, fuel and baggage

must be compared to the limitations, and the wing at-

tachment to the fuselage position must be within the

limits as specified in the POH. The cart must be bal -

anced properly or an unsafe cart configuration, either

nose-high or nose-low will result.

The Preflight Checklist

Use a written checklist during preflight and ground

operations. The checklist is an aid to the memory and

helps to ensure that critical items necessary for the

safe operation of the aircraft are not overlooked or

forgotten.

Certificates and Documents

The airworthiness of the powered parachute is de -

termined, in part, by the following certificates and

documents, which must be on board the aircraft when

operated:

• Airworthiness certificate.

• Registration certificate.

• Operating limitations, which may be in the

form of an FAA-approved Aircraft Flight

Manual and/or Pilot’s Operating Handbook

(AFM/POH), placards, instrument markings, or

any combination thereof.

• Weight and balance

AROW is the acronym commonly used to remember

these items. The pilot in command is ultimately re -

sponsible to make sure the proper documentation is

on board. [Figure 5-4]

Aircraft logbooks are not required to be on board the

powered parachute when it is operated. However, you

should inspect the aircraft logbooks prior to flight to

confirm the PPC has had all required tests and inspec-

tions. The owner/operator must keep maintenance re-

cords for the airframe and powerplant.

At a minimum, there must be an annual inspection

within the preceding 12-calendar months. In addition,

the powered parachute may also need a 100-hour in-

spection in accordance with 14 CFR part 91 if it is

used for hire (for example, for training operations). If

a transponder or a transponder/encoder with a pitot-

static system is used, it must be inspected within each

preceding 24-calendar months.

The pilot must have in his or her possession a valid

U.S. driver’s license, or a valid medical certificate

accompanied by a photo identification and pilot cer-

tificate. Sport pilots must also carry a copy of the en-

dorsements issued from their logbook indicating they

are qualified for the powered parachute category/class

for the aircraft they are flying. The wing shape (rec-

tangular or elliptical) and the landing system (land or

sea) will be specified in this endorsement.

the aircraft at all times.

Visual Inspection

The accomplishment of a safe flight begins with a

careful visual inspection, regardless of the category/

class of aircraft you will be flying. The purpose of the

routine preflight inspection is twofold: to determine

the powered parachute is legally airworthy, and that it

is in condition for safe flight. You determine whether

the PPC is in a condition for safe flight by a thorough

and systematic preflight inspection of the aircraft

and its components. The preflight inspection should

be performed in accordance with a printed checklist

provided by the powered parachute manufacturer for

the specific make and model of aircraft. However, the

following general areas are applicable to all powered

parachutes.

The preflight inspection should begin as soon as

you approach the aircraft. Since the powered para -

chute can be transported by trailer, the unloading of

the aircraft allows you extra opportunity to look the

cart over from front to back and top to bottom. First

and foremost, you need to look for any damage that

may have occurred during transit. Make note of the

general appearance of the aircraft, looking for obvi -

ous discrepancies such as tires with low air pressure,

structural distortion, wear points, cart damage, and

dripping fuel or oil leaks. All tie-downs, control locks,

and chocks should be removed during the unloading

process.

It is absolutely necessary you are thoroughly familiar

with the locations and functions of the aircraft sys -

tems, switches, and controls. Use the preflight inspec-

tion as an orientation when operating a make/model

for the first time.

The actual “walk around” is a routine preflight inspec-

tion and has been used for years from the smallest

general aviation airplane to the largest commercial

jet. The walk around is thorough and systematic, and

should be done the same way each and every time an

aircraft will be flown. In addition to “seeing” what

you’re looking at, it requires you take the appropri -

ate action whenever a discrepancy is discovered. A

powered parachute walk around will cover five main

tasks:

1. Cart inspection

2. Powerplant inspection

3. Equipment check

4. Engine warm-up and check

5. Wing and suspension line inspection

Each PPC should have a specific routine preflight in-

spection checklist, but the following can be used as a

guideline for most PPCs.

Cart Inspection

Check the front nosewheel for proper play, tire infla -

tion, and secure axle bolt. Test the ground steering bar

connection points and ensure there is smooth steering

range of motion from the steering bar. Check and se-

cure the connections between the front fork and the

front axle and the front fork and the gooseneck. [Fig-

ure 5-5]

Figure 5-5. Check for proper tire inflation and that the axle

bolt is secure.

When brakes are installed, it is common for them to

be on the front nosewheel. Typically, they are drum

or disk style operated by a cable; it is important to

inspect the cable lock, assuring it is tight. The brakes

may be hydraulic disk brakes that also incorporate a

cable; in this case, inspect both components. Check

brakes and brake systems for rust and corrosion, loose

nuts/bolts, alignment, brake pad wear/cracks, signs of

hydraulic fluid leakage, and hydraulic line security/

abrasion.

Inside the cart where the pilot sits, check the seats,

seat rails, and seat belt attachment points for wear,

cracks, and serviceability. A few manufacturers offer

powered parachutes with adjustable front seats. The

lever moves the pin in and out of the seat rail holes

and the seat then moves forward and back along the

rail. The seat rail holes should be checked for wear;

they should be round and not oval so there is no play
