2Military Aircraft Systems Safety FeaturesThe safety features of air-launched weapons are designed to protect the aircraft and ground-crew, and to ensure that the weapon is armed and released only when required. Some safety features are managed by the ground-crew, some by the pilot, and some are internal to the aircraft or the weapon itself.
3Military Aircraft Systems Safety FeaturesAll new weapons are subject to rigorous testing prior to being cleared for use on an aircraft. This ensures that they are carried and released safely.
4Military Aircraft Systems Key Missile FeaturesSeeker – Locates target and feeds this informationto the Guidance Unit.Guidance Unit – Takes the target information fromthe Seeker and sends it to the Navigation System.Navigation System – Takes the target informationfrom the Guidance Unit and uses it to direct theweapon to the target.Actuation System – The Actuation System controlsany moveable fins that steer the weapon.
5Military Aircraft Systems Key Missile FeaturesArmament Section – Contains the payload, fusing,safety & arming devices, and the target-detectingdevices.The payload (warhead) is the explosive content.The fuse controls when the explosive detonatesand can be either proximity, impact or time-delay.Propulsion System – The means by which a missilepropels itself.Usually either a rocket motor or a small jet engine.And all missiles don’t become fully armeduntil the missile has achieveda pre-determined acceleration

7Safety Features Rail Launchers When a missile is fired, Air-to-Air missiles are carried on Rail Launchersto provide the data andelectrical connectionsbetween the aircraftand the weapon.When a missile is fired,they allow the missileto leave the aircraft safelywithout striking the airframe.
8Safety Features Rail Launchers There are four rail launchers in use with the RAF:LAU-7/A and BOL-304(Tornado GR4)Integrated Tip Stub Pylon Launcher (ITSPL)(Typhoon FGR4)andMulti-Function Rail Launcher (MFRL)LAU-7/A BOL-304ITSPLMFRL
9Safety Features Safety and Arming Devices are electromechanical, Missile safety and arming devicesare electromechanical,explosive control devicesdesigned to protect the aircraft and ground-crew,to protect a launch aircraft when it fires a missile,and to ensure that the weaponis armed and releasedonly when required.
10Pilot-Controlled Safety Features The pilot-controlled safety features ensure that the weapons are armed and released only when required. There are three key controls in a combat aircraft cockpit to manage weapon safety: Master Armament Safety Switch Late-Arm Switch Emergency Stores Jettison
11Safety Features Pilot-Controlled Safety Features Master Armament Safety Switch (MASS)The pilot enables the master armament switchthen selects the weaponand presses the firing button.Late-Arm SwitchThe Late-Arm Switch needs to be selectedto allow the armed weapons to be released.Emergency Stores Jettison SwitchThe Emergency Stores Jettison Switchallows the pilot to release all external storesin the event of an emergency.
12Safety Features Fuse Mechanisms When a GP Bomb is released from an aircraft,to ensure the releasing aircraft is not endangeredby the high explosive content,the fusing mechanism is in a safe state,until the arming vane at the rear of the tail unithas made sufficient rotations to ensurea safe distance from the release aircraft.
13Check of Understanding Which of the followingare standard components of Air-to-Air Missiles?Guidance, Fuse, Control Surfaces, Power Supply.Power Supply, Radome, Fuse, Warhead.Seeker, Guidance, Rocket Motor, Warhead.Seeker, Fuse, Power Supply,Tail Unit.
14Check of Understanding What controls the steeringof a missile towards its target?The launch aircraft pilotThe missile guidance systemThe launch aircraft navigatorThe missile propulsion system
15Check of Understanding The Armament section ofan air-launched missile contains:The payload, fusing, safety and arming devicesThe arming andtarget-detecting devicesThe payload, fusing, safety and arming devices, and target-detecting devicesThe payload and fusing
16Check of Understanding At what point does a launched missilebecome fully armed?Just before it hits the targetWhen the missile has achieveda pre-determined accelerationWhen the missile has achieveda pre-determined distanceWhen the missile has achieveda pre-determined speed
17Check of Understanding What protects a launch aircraftwhen it fires a missile?The missile safety and arming deviceThe pilot arms the missile when it isa safe distance from the aircraftThe missile warhead cannot detonate until it hits the targetAn electromagnetic signal from the launch aircraft arms the missile when it is a safe distance from the aircraft
18Check of Understanding When a GP Bomb is released from an aircraft,what safety feature ensures that the aircraft is not endangered by the high explosive content?The fusing mechanism has a built in sensorand only arms when 200ft from the aircraft.A GPS timer is enabled at the point of releaseto ensure the fusing mechanism is not armeduntil 300ft from the aircraft.A speed sensor activates the fusing mechanismto provide a safety distance of between200ft and 300ft from the release aircraft.The fusing mechanism is safe untilthe arming vane makes sufficient rotationsto ensure sufficient safety distancefrom the release aircraft.
19Check of Understanding What causes a missile to be launchedfrom a piloted aircraft?The pilot by pressing the firing buttonThe pilot by selecting the weaponand then pressing the firing buttonThe pilot enablingthe master armament switchthen selecting the weaponand pressing the firing buttonThe aircraft launches missiles automatically
