Your safety briefings should include
the effects of C of G changes.
Deplaning Procedure
Seat belts must be unbuckled as
instructed, then rebuckled. Only one
person or item of cargo should leave
the helicopter at a time, from the left
side, with the weights gently
transferred to the ground. One
person should ensure that all doors
(passenger and cargo) are closed
after everything has been unloaded.
Persons and cargo should remain
grouped ahead of the passenger door
until the helicopter has departed.
Emplaning Procedure
Seat positions should be determined
beforehand, with persons and cargo
grouped in one location beside the
intended arrival area.
People must only approach when
signalled (either thumbs up, or an
exaggerated head nod), from the left
side, with only one person or item
entering the helicopter at a time.
Weights should be gently transferred
from the ground to the helicopter.
Seat belts should be immediately
fastened once persons are seated,
and doors closed.
Formation Flying
Used when chasing another aircraft,
but not at night, in cloud, or when
the cloud base is below 500 ft or
visibility below 3 km. As the pilot of
the other machine may not be aware
of your intentions, and might not
even wish to be identified, you
shouldn’t do this too closely. In
other words, spend the shortest
possible time at the minimum
permitted distance from the other
machine, and shadow from the
maximum range consistent with
getting photographs, or other
evidence, and maintaining visual
contact. Remember one official
definition, which is "flight by sole
reference to another aircraft"
Do not endanger the other machine
or attempt to force it to alter height
or heading, or to land, because you
may need to take safe avoiding
action if the other machine attempts
to endanger you.
If you cannot establish RT contact,
approach while the target is in
straight flight, which may be level, or
climbing, or descending. Establish a
stand-off position behind, between 4
and 8 o'clock, not closer than 200m.
Reduce the range slowly and
progressively to at least 100m,
moving back out once the required
evidence of registration, type and
other features have been noted.
Landing Helicopters on Roads
The area must first be secured (but
see below), with radio or verbal
communication having taken place
to confirm that you have authority to
land there. Unaffected carriageways
should be closed at all times.
Normally, you can only land at an
unsecured site (i.e. where the police
are not in attendance) in remote
rural areas outside congested areas,
but you may do so on dual
carriageways (divided highways) or
motorways (turnpikes) in daylight,
where no traffic is moving—no
landings should be made by night.
In any case, there must be no threat
to persons or vehicles on the ground
from the helicopter, or vice versa.
Always be aware of the effects of
your downwash, which may blow

away crucial evidence, not to
mention dislodging broken glass and
other loose debris, particularly from
damaged buildings, at bomb scenes.
Try not to land in school or other
play grounds, or areas where
children might be confined or
suddenly emerge. Don’t use the
aircraft presence or public address
system to clear children from a site.
Parachute Dropping
In UK, no parachute dropping
should be undertaken unless (as a
pilot) you've been approved by the
British Parachute Association and
the parachutists themselves are in
possession of an Operations Manual
authorised by them. It’s probably
similar elsewhere. You get your
certificate by passing a check ride
with a TRE, who in turn has been
approved by the BPA. The normal
regulations for the dropping of
articles from aircraft also apply. In
addition, the Flight Manual should
include a Supplement to cover the
situation. For some strange reason,
parachutists do not seem to be
classed as passengers or freight, so
it's a good question as to whether a
parachute trip is actually Commercial
Air Transport or not. Check your
insurance cover, even though on the
way down they are not in the
aircraft, and on the way up they are
normal passengers.
Parachutists should be strapped in at
all times except immediately prior to
dropping, and before takeoff they
