skywalker22 Posted July 13, 2021 Share Posted July 13, 2021 I know (at least I think) how to perform a cold start on F-16. So, offline always all fine, online it happened few times in last few days, it just didn`t wanna start. When engine reached 60%, it just shut off. Tried everything I know, with pump Start 1 and Start 2 knobs, but it didn`t make any difference. There must be some trick to start it, some different procedure or something.

ice41 Posted July 13, 2021 Share Posted July 13, 2021 Not certain if it is the cause here. But why is ELEC only on BATT and not MAIN PWR? Link to comment Share on other sites More sharing options...

Also tried on main power, but result is the same. Although usually I put on Main Power afterwards when engine settles down at 65% and TIT at around 400C.

_SteelFalcon_ Posted July 13, 2021 Share Posted July 13, 2021 Looks like buddyspike. Afaik you spawn with 0% fuel there, so make sure to talk to the ground crew when the battery is on and request refuel before you crank the engine 1 1 Link to comment Share on other sites More sharing options...

Do you know for sure that there was fuel in the jet? Edit: looks like SteelFalcon beat me to it Edited July 13, 2021 by ice41 1 1 Link to comment Share on other sites More sharing options...

skywalker22 Posted July 13, 2021 Author Share Posted July 13, 2021 (edited) Yes, it was that. There was no fuel onboard. So 2 things: 1. there should be some indicator "No Fuel", right? 2. why the engine did start and ran for 15sec if there was no fuel on board?

Frederf Posted July 13, 2021 Share Posted July 13, 2021 (edited) The fuel sensing system requires certain electrical power and I don't know if that is on before the engine is running. If you use ground power you do get the low fuel indications. Realistically there is some unusable fuel in the system which is usable. The unusable fuel figure is calculated for an aircraft fuel tank in "the most adverse fuel feed condition occurring under each intended operation and flight maneuver involving that tank", at least for FAA certified airplanes which the F-16 might not be. It is perfectly reasonable for fuel state 0 to have some fuel on board. The JFS has access to fuel directly (even with master to engine off) and probably can run under fuel conditions the engine itself can't. If 0 fuel state corresponds to not a single drop of JP8 in the airplane then the JFS light probably should not illuminate as that only happens in the normal working RPM range. I think that requires fuel. The FTIT during start rises to over 800C which is simply not possible unless fuel is present. If the start process is "canned" in the simulation and doesn't check fuel until the process is over then that would be a limitation of the simulation. Otherwise it could be modeling some quantity of fuel available for JFS and engine operation even though the editor value is 0. What I'm curious to test if is running the JFS burns fuel. It should. EDIT: From test JFS is not burning fuel. Edited July 13, 2021 by Frederf 1 1 Link to comment Share on other sites More sharing options...
