Tinkickef Posted December 4, 2018 Posted December 4, 2018 (edited) I have random failures on at 1% so I don't get them frequently. I have had nozzle and fuel metering failures in the past, but nothing for months. Last night I had an impressive one. I had launched a missile and the Hornet wanted to roll over onto its belly at around 450kts. At first I thought it was because I had asymmetric loads, but it was extreme. No warning indications. Looking back at the wings revealed the starboard slat was drooping at full extent and the port slat was fully up. A look at FCS page revealed nothing. FCS reset did nothing. Slowing down and cycling the flaps did nothing, but with full flap the aircraft did at least behave. Of course, then I had to keep resetting the gear alarm, so it was easier to drop the gear. I can tell you that Bandar Abbas to Al Dhafra is a Hell of a long way at 140kts...... Once home, before I shut down I took a F2 looksee with flaps on auto. Yup, stb flap up, stb slat drooping. Impressive systems modelling, it seems the slats are modelled independently of the flaps.

Shadow KT Posted December 4, 2018 Posted December 4, 2018 Nice, would be nice to know what the procedure would be in this case 'Shadow' Everybody gotta be offended and take it personally now-a-days
JayBird Posted December 4, 2018 Posted December 4, 2018 Random failures are awesome. I've been flying with them recently and it makes things a lot more interesting.

Rescue Posted December 4, 2018 Posted December 4, 2018 Maybe WIP so that the FCS Page shows nothing and Reset doesn't solve the Problem? Maybe the failures are also WIP so this failure wouldn't happen this way? Didn't know the frame of the F-18 that good like the A-10. So I didn't know it's may be a hydraulic failure, but that would mean flaps full wouldn't work. Really interesting though. Is there any "professional" who can bring some light into this?
Yoda967 Posted December 4, 2018 Posted December 4, 2018 IIRC, Duke Cunningham wrote about a failure in his F-4 that locked the jet at full nose up trim. They were feet dry over North Vietnam at the time, so he had to get them out over the water to bail out...what worked was a continuous series of rudder rolls. Good on you for figuring out a solution that got you home, whether the failure was "realistic" or not.

VZ_342 Posted December 5, 2018 Posted December 5, 2018 Some in-flight emergencies don’t have specific protocols. You simply treat the symptoms if possible, and if flight control is unrecoverable and/or below a certain altitude then one ejects. For example, in the EF111, the -1 describes “uncontrolled 3 axis gyration” with essentially two sentences: 1. Do not separate wing stores; and 2. If flight control has not been restored by 20,000’ AGL, EJECT. Somehow I don’t think the aircrew would try searching for (or reading) emergency procedures during an emergency. :joystick: Tinkickef handled it quite effectively by treating the symptoms as they presented. :thumbup:
