Forum: F-16 Design & Construction

Hi All Falcon experts,
What is the different functionality between the procedure of starting engine of F-16A and F-16C? I know that F-16C u need only to start the JFS toggle switch and the engine will start......correct me if I am wrong, but is this the same to F-16A? Is the engine start procedure for F-16A same as F-16C?

You can't just jump in and hit the JFS switch. If I remember right and it has been a couple of years since I was in a cockpit;
you have to set your FlCS switch, Power and Engine Feed and then start your JFS.

The only real difference I see between the blocks are digital and analog flight controls and I assume that only matters for verifying operation, i.e veryifying bit, power, etc.

I'm going to keep my eye on this post, it's gonna be a beauty and probably very long.
Lets start with this, what Block F-16C, F100 or F-110 (RPM over the horn difference), 25's and 30's don't have DFLCS and so on, have fun guys.

I have no idea about F-16A and I really wanna know too. I just know about the F-16C and according to me " nam11b " is 100 % right. According to me, F-16C is way easier than F-16A. U can just note the difference by the cockpit layout. Man, F-16A's cockpit is horrible, it puts so much stress ( atleast on me if I were a fighter pilot ). And, F-16C's cockpit is really easy and so, it is a pilot-friendly cockpit.

You think a C model c-pit is easier for the pilot you should see a Raptor c-pit

Yasir,
When you say the F-16A cockpit is horrible, remember it was designed in 1972 with the best diisplay technology available then. A lot of new computer and display technology has been developed since that time. People born in the last 30 years don't realize what a revolution computer technology has been.

I remember that I tried to train the start up procedure for a F-16 with Falcon 4: Allied Forces, it partially worked.

When I got into the real F-16 simulator it was a MLU and not some very early block, which I trained to, I expected to see a lot of switches and I was like "WTF" when I pushed 2 or 3 buttons it was running.

In terms of just starting the engine they had different engines if we are referring to the original F-16A (block one) and the original F-16C (block 25)
The F-16A had the F-100-PW-200 while the F-16C has or had PW-220. The JFS was, AFAIK the same and still used ESS controller back then. In term of starting, I believe it was the same process, except the obvious different engine parameters. Also, their is a bit more to it than just: "start the JFS toggle switch and the engine will start".

The original question was about starting the engine. No diference here between A and C models: Main Power- Start 1- Throttle Idle and watch!

I thought it was start 2?

What about the Idle Detent switch?

I have tried to find it so many times, but can't find it.

Is this the switch (at green cursor) ?

--It can be ether one, start 1 or 2
Start 1 you use one JFS/Brake accumulator while 2 you used both accumulators.
IIRC, the T.O. recommends Stat 2 fro several temperature ranges but, I have started the jet many time on start 1.

--What did you need to know about the Idle detente switch? You should not need to pull it to start the engine, you should only need to use it to shut down the engine.
The idle detente is the little trigger on this picture at the base of the throttle grip

In F4:AF and this checklist it states that you have to toggle the Idle detent, at the moment when you want the engine to go from 20% to 70%

When I fly in F4:AF I HAVE to use that toggle before I can go to 70%

When I ran the aircraft, I do not remember having to pull the trigger, My memory is not what it just to be I guess.
Also remember in the game, there is no other way to simulate lifting the throttle grip, so that is one of the reason that they implemented that, AFAIK.
Also runi, there are never exact numbers on the engine parameters in real life IIRC, at least non that I remember. Instead there is a range of numbers, for example, Idle in a GE is somewhere between 60% to 80%, PPH is 700 to 1600 and so on.

The trigger is used only during shutdown. Its to prevent engine shutdown when pulling the throttle fast during decell. Pretty important thingy because its operation and rigging is checked every 50 flight hours with most operators.

F-16A models have what's called the BUC Idle Detent as well. When BUC is selected the detent would drop down on the throttle gate and you have to rotate the throttle outboard and fwd again to set it against the BUC Idle detent. Then you would be in what is considered "BUC Idle"

Different between F-16A and F-16C
