What are 6 aircraft danger zones |
Propellers Rotors Disintegration areas Engine intakes Engine exhaust Noise exposure |
|
|
Dangers with props |
Wake, from thrust Windmilling Strobotic effects (appearing stationary) Stationary blade (hitting head) |
|
|
What is the main safety precaution for propeller driven aircraft |
Never walk through the prop arc especially when ground power is connected to the ac |
|
|
Dangers with rotors on ac (one point splits in two) 3 |
Main rotor, sail and sloping ground Tail rotor Down wash |
|
|
6 safety precautions to observe when working around Hele copters with running engines. |
Approach and leave with permission from person in pilots seat only. Approach and leave from designated safe zones specified in ssrps Never walk under rotor disk during start up or shut down Avoid tail rotor and exhaust areas when aircraft is running Beware of rotor to ground clearance when on uneven surfaces Beware of the effects of down wash |
|
|
4 times ac anti collision beacon is used |
Aircrew in control Ground running Ground pressure testing Radiation hazards |
|
|
What's HERO, HERF, HERP |
Hazards of electromagnetic radiation to ordinance Hazards of electromagnetic radiation to fuel Hazards of electromagnetic radiation to personnel |
|
|
Regarding RADHAZ what should bot be operated during fueling and defuelling |
Aircraft transmitting equipment |
|
|
What can cause HERO (3 |
Radio frequency, radar transmission, anoinics systems |
|
|
What are 6 rules used to prevent HERO. (distances of devices) |
No radio transmissions from vehicles within 10 meters of ac No ac radio transmissions within 20 meters of the ac NO transmissions from the ac its self No transmissions from flightline radios within 5 meters of ac No transmissions from visiting /civilian ac. Contact with the tower may be needed to ensure suppression. No portable phone transmissions within 5 meters of ac |
|
|
Regarding HERF. What 2 requirements are needed to prevent ignition. |
Fueling and defuelling ops are to be carried out so that the fuel zones are at least 10 meters from any operating VHF or UHF radio, 30 meters from any operating HF radio and 30 meters from any radar. Approved flightline radios of less than 5 Watts output can be used up to the fuel zone boundary |
|
|
What 2 things can happen to personnel from HERP |
Causing burns or shock making contact with the ac aerial Charging metal items in close proximity to the ac aerials, or by sparking from one charged area to another causing ignition of volatile liquids, fire or explosion |
|
|
Radiation hazard safety precautions to be observed when radiating. 4 |
Anticollision beacon to be on to indicate the hazard is present No replenishment during radio or radar transmission testing Suitable warning notice Safety person keeping personnel away from radiating area |
|
|
Types of explosive operated equipment on aircraft. 10 |
Canopy jettison Emergency exit Ejector racks Countermeasures Pyrotechnics Emergency exit slides Automatic fire extinguishing system. Ordinance Aircraft winch(cable cutter.) Explosive floats. (nh90) |
|
|
2 safety devices methods to prevent accidental operation of a explosive ordinance switch. |
Guarded arming switch Ground safety lock out pins |
|
|
3 danger areas of an aircraft for explosive ordinance directions and devices in these areas |
Forward, firing weapons Aft, firing weapons Radial, flares |
|
|
Safety precautions to be observed when working around explosive ordinance. 4 |
Only personnel required for the task to be around the aircraft and immediate vicinity. No replenishments during loading or unloading of EOE. Suitable warning notice, signs, flags or cones to be placed to indicate EOE is in use. EOE is to have safety pins, locks fitted at all times and removed just prior to flight. |
|
|
What's the purpose of aircraft safety devices and what are the 3 types. One being physical lock, pin. What is the 2 control measures |
Purpose it to disable systems so they cannot be inadvertently operated. Types, Isolating lock, pin Control lock, pin Physical lock, pin Control measures, Placards State board |
|
|
When are 5 times a placard is used. |
No electrical power is to be applied. Flight controls are not to be operated. The aircraft is on Jack's. Engine controls are not to be operated. No hydraulic power is to be applied. |
