Landing with a engine out..

[Fonz_408]

So last night flying on a PVP server I was ground pounding and only had fuel for the run in strike and the flight home.. I was bumped buy a Su33 I had 2x120c on the belly so I could defend myself but... tried to select zone 5 and disengaged.. however the Su33 really wanted that fight and must of gone full burner to stay in the fight, after he got on my 6 and within 20nm... (SA page) I was left with no option but to dive for the deck find a Mt to break his lock.. AARQ mode fire at 10nm stayed hot nose on with a F pole and splashed him... now I was in a spot of trouble.. after climbing back to 20k I had 1000ib fuel left and my base at 60nm.. this is when the title comes into play.. I shut down my L engine and glided most of the way home... landed with 30ib of fuel left.... if you have not tried landing the hornet with one engine I strongly recommend giving it a go... this plane has such a great Flight model and it Really is fun.. give it a go.

Very interesting experience with the Hornet.

I take it the Hornet would fly straight with one engine.

Did you land with one engine running too?

[norbot]

Is flying with one engine off really more economic, than flying with the engine on idle? I would rather expect the drag of a shut down turbine being higher than one running on idle. What is your practical experience? :huh:

[bbrz]

Just tested and I'm not sure if the drag of the windmilling engine is high enough on the DCS F/A-18. (or if idle thrust of the operating engine is high enough).

At 17000ft at 220kts the ROD was 2900-3000fpm with both engines at idle, and with one engine shutdown the ROD increased by ~200fpm.

That seems to be rather optimistic considering that the total fuel flow is reduced by 50%.

Although I can't comment on whether its more fuel efficient or not, I have landed the Hornet with a single engine (right out) on the boat a few times.

 

Its really surprising how well the Hornet actually behaves with only one side burning, there isn't too much adverse yaw, a bit of rudder trim and you can make a windy Case III with little issues.

 

Also, theres a certain thrill that comes with entering the downwind with less than 300lbs

“302, Hornet, Ball, 0.3!!!” :lol::thumbup:

[fitness88]

When closing an engine, it's necessary to press and hold 0 or 9 until the rpms drop below 30, only then can you release otherwise the engine will restart.

Is there another way to do it without having to hold down the finger lift command till <30?

[bbrz]

To correctly shutdown the engine, simply move the throttle to IDLE and thereafter to OFF. That's it. No fuel flow, no restart.

 

That's also the correct procedure in case you need to shutdown the engine, e.g. after an unrecoverable compressor stall etc.

 

Note: Keep at least 85% RPM on the operating engine to avoid MECH reversion.

that's 0.03 not 0.3 :D

[bbrz]

Actually it would be a whopping 0.1 at the ball call ;)

The great advantage about a 0.1 fuel state is that you don't have to consider a wave off.:lol:

At idle the engine is still powered on at around 65% it's not off?

What is MECH reversion?

Again, once the throttle is at IDLE (~65%) you have to move it to OFF. You can't move the throttle to OFF if it isn't at idle.

Like during engine start, only the other way round ;)

MECH is the mechanical back up for the stabilator pitch and roll control.

I have the throttle at 65% I then press 0 or 9 the corresponding throttle then goes back a little to the off position but the moment I let go the 0 or 9 the throttle jumps back to idle and ramps up to 65%...only if I press and hold 0 or 9 till the rpm is below 30% will the throttle stay in the off position.

[bbrz]

I think that you have to use separate keys for Throttle OFF and Throttle IDLE.

AFAIR the problem you are experiencing happens when you assign a key for the combined Throttle OFF/IDLE command.

Right you are...I was using the key combo off/idle.

Thanks for the explanation.

[bbrz]

glad I could help :)

Thanks for bringing this subject up Fonz_408. It was fun to try it.

I tried trapping on the boat twice and both times the JBD for cat3 was raised when I trapped:huh:... didn't crash though. The hardest part for me was trimming for yaw and roll.

 

 

Edit: The approach was done with full flaps. Setting flaps to half will give a wider margin for controllability, up to 12' AOA v. 10' AOA with full flaps. (that's what NATOPS says)… time to go to PAX River and play the test pilot. I might even try shutting down one engine with flaps lowered already... should be fun, especially at low altitude... if DCS modelled all this stuff correctly.

Would be great if we had that modelled actually. FFB rings in my ears there...

The correct procedure for engine failure on landing configuration is still to retract the flaps to half as part of the boldface. In any case nothing stops you from giving it a try on full in DCS :)

Are you subscribed to the FPP? :smilewink: :music_whistling:

[bbrz]

?

[Hog_No32]

Nevermind then. Jell-O (or Sunshine, not sure...) told the story of doing an FCF which required shutting down one engine. He then accidentally went below 85% on the running engine and therefore MECH kicked in...

[bbrz]

LOL, I only quoted the relevant -1 part.

[Hog_No32]

That‘s why I began with „Nevermind“...

[bbrz]

Back in my time, in our fast jets the elevator was fully servo assisted, the ailerons 60% and the rudder had none.

Really basic and no need to worry, even in case of a total hydraulic failure.
