1. List safety precautions to be observed when working around or flying in a helicopter.
2. Define the requirements and procedures to safely perform special missions.
Through lecture, and class discussion this unit will help students obtain an overall knowledge of general aviation safety, pre-flight and in-flight, aviation watch outs and an overall understanding of special mission safety.

AIDS & CUES
Unit Title Slide. Present Unit Objectives. The purpose of this unit is to provide you with information and skills to perform your job safely in and around helicopters.
Many accidents and incidents could have been prevented if the established policies and procedures were followed.
Helicopters are potentially dangerous to all personnel. Through application of the following safety practices, the helicopter operations environment can be safe.
i. general Aviation safety
A. Safety Precautions
Helicopter operations will be limited to missions approved on the Aircraft Data Card and the Pilot Qualifications Card. If you have not flown in the aircraft or with the pilot recently you should ask to see both cards. The pilot is required to carry the pilot qualifications card, and the aircraft data card is required to be in the aircraft.
Helicopter operations will comply with the user agency manual, Helicopter Contract and Federal and State Occupational Safety and Health Act. Standards applicable to the general safety rules for operations and practices.
Flight following and flight planning will be in place and conducted based on agency policy.
Operation of the helicopter will be during daylight hours only. (Defined as one-half hour before sunrise to one-half hour after sunset.)
Helicopter pilot duty and flight limitations have been established by the agencies in an effort to reduce pilot fatigue.
No unnecessary passengers will be aboard the helicopters.
Do not allow unnecessary flights.
Helicopters shall not be dispatched for mountainous flying when average wind velocity exceeds agency or manufacturer limitations.
Personal protective equipment required for all missions-available and worn by all ground personnel, passengers and pilot.
On the ground and in the air safety precautions
Safe use of the helicopter at all times.
Participate in the helicopter safety program and the efficient use of the aircraft.
Approve all missions; the pilot’s word is final as to whether or not the flight can safely be made.
Ensure mission objectives and hazards are clear and understood.
A passenger may refuse to fly with any pilot or in any aircraft or curtail an existing flight if, in the opinion of the passenger, conditions exist which make the flight unsafe.
B. General Helicopter Safety
Keep clear of helicopter’s rotors.
Unless loading or unloading, stay outside safety circle at all times.
Approach or depart in a slight crouch from front or side in full view of the pilot or as directed by the pilot or helitack personnel.
Under no circumstances go near the tail rotor of the helicopter.
Do not approach from or depart to an area where ground is higher than where the helicopter is sitting or hovering.
Never run when approaching or leaving helicopters.
Carry equipment parallel to the ground.
Obtain pilot’s approval for all gear stowed in or on the helicopter, especially explosives, flammable, or other hazardous materials.
Cargo in racks or cargo compartments must be tied down securely.
Know location and operation of doors and emergency exits.
Know location and operation of:
All DOI and Forest Service aircraft must have a hand held minimum 20B:C rated fire extinguisher.
Emergency location transmitter (ELTs)
Every aircraft must have an ELT.
Aircraft owned or operated by DOI and Forest Service are required to carry a first aid kit.
The first aid kit must be readily accessible to all occupants in the aircraft.
Survival kits are required for all special use activities and are recommended for all missions. Survival kit (minimum contents)
All aircraft must be equipped with an FAA approved restraint system.
All restraint systems must have a metal-to-metal buckle or latching mechanism.
Keep belt fastened during flight.
Three types of restraint systems:
Two-point (if applicable)
Front seat occupants of a helicopter must have a four-point harness.
Make sure lap belts are refastened before closing door
Fuel and battery shut off
Know location and operation, specifically which to shut-off first in the event of an emergency
Use a chin strap or secure hard hat when working close to the helicopter.
No smoking within 100 feet of helicopter or fuel trucks.
One-wheel, one-skid, hover stepping, or power-on landing will not be performed without written agency approval.
Keep arms and legs clear of controls and inside helicopter.
Control objects, such as maps, etc., so as to not restrict visibility.
Keep hardhat, gloves and other PPE on.
Locate the emergency exits and know how to operate. Use only in emergency.
If suspect becomes combative, restrain the suspect and notify pilot to land in a safe area.
No smoking at any time while in flight.
Keep alert for aerial hazards, particularly other aircraft and power lines; inform pilot of their presence.
Always know your location so you may assist in flight following and maintain situational awareness.
Do not throw objects out of helicopter unless trained in procedures and pilot approval is obtained.
D. Common Questions and Concerns to Consider
Refer to IRPG aviation blue section for list of watch out situations. Go through list with students and discuss each situation. 1. Aviation Watch out Situations
Is the flight necessary?
Who is in charge?
Are all known hazards identified and have you made them known?
Should you stop the operation or flight due to change in conditions, communications, confusion, conflicting priorities, weather, turbulence, personnel?
Is this the best way to accomplish the mission?
Are you driven by an overwhelming sense of urgency?
Can you justify your actions?
Are there any other aircraft in the area?
Do you have an escape route?
Are there any rules being broken?
Are communications getting tense?
Are you deviating from assigned operation or flight?
2. Other Questions to Consider
Do the risks outweigh the benefits of the operation?
Is there an adequate safety margin?
Has adequate planning been accomplished?
Are the pilot and helicopter carded and equipped for the mission?
Are there sufficient qualified personnel to accomplish the mission?
Has there been an adequate planning and hazard analysis?
Is there adequate equipment to accomplish the mission?
Have all personnel been briefed on the mission and a positive communication established?
Are contingency plans in place for changes due to bad weather or equipment failure?
Ii. special mission safety
A. What Is Special Use?
Special use is operations involving the use of helicopters in support of DOI and U.S. Forest Service programs, which require special considerations due to their functional use. Pilot and aircraft must be carded for special mission.
Example of Special Use:
