Updated: 10Sep2020 # Electrical Power System All main electrical power in the F-14 is generated from the two engine driven AC generators. The generators connected to the gearboxes on the engines are each capable of generating enough power to individually drive all aircraft systems. As for DC power generation the F-14 has two transformer-rectifiers supplying 28 V DC, and again each one is individually capable of driving all aircraft DC appliances. The F-14 has an external power receptacle for AC power just aft of the nose gear, capable of driving aircraft AC and DC (through the transformer-rectifiers). External power is automatically disconnected from the aircraft power system when one of the internal generators come online. # Emergency Power The F-14 has an emergency generator driven by the combined hydraulic system generating a limited supply of AC and DC power. If the system loses main power the emergency generator takes over supply of flight critical systems within 1 second. # Master Generator Control Panel Located in position 11 on the diagram to the right. ![[F-14 Pilot Cockpit Panels.png]] # Master Generator Controls 1. **L & R MASTER GEN** switch 1. **NORM** - Normal, activating and connecting generator to the main buses. 2. **OFF/RESET** - Disconnects and deactivates generator and resets tripped protection circuits. 3. **TEST** - Activates generator but does not connect it to the main buses, for testing purposes. 2. **EMERG** switch - Guarded switch controlling connection of emergency generator to essential buses. (NORM is guarded) 1. **NORM** - Normal, generator is automatically connected to essential buses if both main generators fail. 2. **OFF/RESET** - Disconnects the generator from the essential buses regardless of main generator status. Resets protection circuits. ![[Pasted image 20230905174341.png]] # Caution and Advisory Lights Associated caution and advisory lights are located on the pilot Caution - Advisory Indicator. The **L GEN** and **R GEN** lights, when illuminated, indicate that the respective generator is not functioning correctly. Either because of a fault or because the engine driving the generator not running. The **TRANS/RECT** advisory light indicates that only one or none of the transformer-rectifiers are functioning. The emergency generator can be tested by selection of **EMERG GEN** on the **MASTER TEST** switch on the Master Test Panel. Completion of the test is indicated by the **GO** light illuminating. In case of a fault the NO GO light illuminates. # DCS Mappings To my (`Data's`) knowledge, these controls are NOT mappable in DCS and have to be clicked on to manipulate. # ELECTRICAL FAILURE >[!failure] # ELECTRICAL FAILURE CHECKLIST >- [ ] Descend or climb to known VFR conditions. > >>[!caution] >All DFCS functions and spoilers will be lost.
