Captain Orso Posted July 22, 2020 Posted July 22, 2020 Is there a proper was to transition from running off engine power to running off ground power. Everytime I land to refuel and have ground power hooked up, it undervee me that I have to kill the engines -- everything goes black -- before I can start up ground power. Is there a away to switch to ground power before shutting down the engines and everything going black? When you hit the wrong button on take-off System Specs.

Swift. Posted July 22, 2020 Posted July 22, 2020 Probably not. AFAIK ground power is only used for maintenance purposes so there would be no need for it to be a smooth transition. Out of curiosity, why? 476th Discord | 476th Website | Swift Youtube Ryzen 5800x, RTX 4070ti, 64GB, Quest 2
Meyomyx Posted July 22, 2020 Posted July 22, 2020 Here's the work around; Before you shutdown your engines, move the battery switch to the ORIDE position. When you shut down the engines, the displays WILL go blank. Do a ground reset and energise ground power. The screens and systems will come up AND you won't get an FCS error. You will have a battery warning displayed. Do you turnaround. Once you have both engines running again, return the battery switch to the "ON" position and you're good to go. The battery warning will extinguish. 1

Out of curiosity, why? Because if you completely shutdown you lose things like waypoints you've set and sequences, and radio settings, and whatever else there may be. I just want to refuel and rearm and return to the fray :pilotfly: Here's the work around; Before you shutdown your engines, move the battery switch to the ORIDE position.

Ryan3469 Posted July 23, 2020 Posted July 23, 2020 Captain, you don't have to shut your aircraft down to rearm/refuel. Just press LAlt+' to bring up the menu, and click away. No shutting down, no ground power, no problem. :P
Captain Orso Posted July 23, 2020 Author Posted July 23, 2020 I've been doing the shutdown since I don't know when. Maybe I started doing it when I had to do a repair at the same time and it just became routine. Anyway, at this point, it just feels right to me to be doing. I alway open the canopy to feel the breeze on my face for a moment while the ground crew is doing their thing..... and then I ,realize I forgot to turn on the table fan :D When you hit the wrong button on take-off System Specs.

jmarso Posted July 23, 2020 Posted July 23, 2020 Why wouldn't you use your APU if you wanted to shut down, since the Hornet is equipped with one?

jmarso Posted July 23, 2020 Posted July 23, 2020 Because the APU doesn't have a generator. Well that would explain it! Curse those lowest-bid aerospace companies!! :D That does leave me a bit confused though; the P in APU stands for 'power'. So what does the hornet APU do anyway? Just act as an air supply for engine start?

mongo52 Posted July 24, 2020 Posted July 24, 2020 Because the APU doesn't have a generator. While the APU does not have a generator you can do a ground maintenance mode. However I'm pretty sure ED hasn't modeled decoupling the motor so you can windmill it to spin the generator.
QuiGon Posted November 7, 2021 Posted November 7, 2021 So there is no way to smoothly swith from engine electric power to ground power so you can repair your aircraft without having to reboot and realign all the system afterwards? 1 Intel i7-12700K @ 8x5GHz+4x3.8GHz + 32 GB DDR5 RAM + Nvidia Geforce RTX 2080 (8 GB VRAM) + M.2 SSD + Windows 10 64Bit DCS Panavia Tornado (IDS) really needs to be a thing!

Is such a transition at all possible without a temporary power loss? Going by what Tholozor said, no. Because the gens are still online, the ground power switches wont engage. I havent looked at the systems myself, but I do know that the checklist for setting the alert only lists connecting the ground power after shutting down. 476th Discord | 476th Website | Swift Youtube Ryzen 5800x, RTX 4070ti, 64GB, Quest 2
Tholozor Posted November 7, 2021 Posted November 7, 2021 (edited) Correct, the ground power switches cannot engage while the generators are running. So direct transitioning seamlessly from generator power to ground power is not possible. EDIT: Under normal conditions.

Tholozor Posted November 8, 2021 Posted November 8, 2021 (edited) Checking the NATOPS, the ORIDE position on the BATT switch disables the automatic generator reset circuit. The electrical buses are also energized with the BATT switch in the OFF position with the parking brake set. If the BATT switch is ON and the parking brake not set, the buses powered by the right generator will not energize by external power (which will trigger the GEN TIE caution).

norman99 Posted January 15, 2022 Posted January 15, 2022 Don’t confuse naval ground power units and their intended functions with civil aircraft ground power. Civil aircraft are designed to use ground power as part of there every day operations. Loading and unload cargo/catering/cleaning pax all require power, so aircraft use ground power to minimise apu usage. To facilitate this, the electrical systems onboard modern aircraft have no break power transfer systems. My understanding of navy ground power units are they are primarily use by maintenance crew, and are not used in an operational sense. Because of this, there is simply no need to include no break power transfer as a feature in the aircraft.

Tried that, but step 5 seems wrong, because if I turn of my throttles before engaging the GND PWR switches, I loose all my power.

did Posted March 3, 2022 Posted March 3, 2022 Ground power used for maintenance AND for fast start. Like on alert 5, get everything align and warm, then start engine when needed. In real life, you can fuel the a/c with engines on. I never seen loading weapon with engines on. DCS is not at all realistic on the time needed to loaded any a/c. Better to have another a/c loaded, ready on ground power with ins, radar and all on, jump in and start both engines. Loading with engines running is a wast of fuel, and loading with power could be explosif, stray voltage and other pleasant unpredicatable outcome.
