fail safe

listen to the pronunciation of fail safe
English - English
Any system that cannot fail in any mode without providing a directly observable indication of failure Consider an electrical relay with a set of contacts that are open when it is unpowered If a power source and a light bulb are connected in series with the contacts, the lamp will glow when the relay is energized If the goal of this system is to insure that the relay has power, then this system is said to be fail safe If the lamp, relay contacts, lamp power source relay coil, or the relay coil power supply fail, then the lamp extinguishes itself providing a directly observable foolproof indication of failure
procedure designed to prevent malfunctioning
A system which closes the throttle and moves the control surfaces to pre-set positions in the event of loss of signal from the transmitter Required by larger models and is intended to bring the model to earth quickly in the event of radio interference or transmitter failure
Something which doesn't cause undue damage, in the event of failure

The system is failsafe, because everything is backed up automatically.

A fail-safe device or mechanism
To compensate automatically, in the event of a failure
eliminating danger by compensating automatically for a failure or malfunction; "a fail-safe device in a nuclear weapon to deactivate it automatically in the event of accident"
{s} completely reliable; protected against failure; pertaining to or equipped with an early-warning mechanism; pertaining to safeguards and controls used during bombing missions (Military)
guaranteed not to fail; "a fail-safe recipe for cheese souffle"
guaranteed not to fail; "a fail-safe recipe for cheese souffle
{i} mechanism which compensates automatically in case of a failure or malfunction
Something that is fail-safe is designed or made in such a way that nothing dangerous can happen if a part of it goes wrong. The camera has a built-in failsafe device which prevents it from working if the right signals aren't received
failsafe
A feature of some Tx and Rx models that support PCM Failsafe is used so that the servo's go to a predefined position if the signal is lost In an airplane this can be to go to a low idle while putting the plane in a gentle turn, but in a helicopter it is not as useful since helicopters are naturally unstable there is no predefined setting to prevent a crash
failsafe
A PCM radio system function, or add-on accessory, which moves servos to a pre-programmed position if transmitter signal is lost
failsafe
(Ticaret) A process that uses controls and logic to stop an improper operation or transaction before it occurs and creates an error condition or defect. ex.- an entry program for distributing a single charge to several departments by percent that will not update if the individual entries don't add up to 100%. (syn: poka-yoke)

failsafe
(See Autoship)
failsafe
A device that is built into a receiver or that plugs between the receiver and servos that prevents a runaway car in the case of battery failure or loss of signal Some new servos can be programmed
