If you just want arcade action and do your solo-play go back to standard BF2! - why PR?

Thats exactly what I meant to say!

tbh, youd think in a wartime situation against a similarly armed adversary, jets would be on a permanant state of readiness in preperation to scramble.

^^^^^ but still, they would need to get engines ready and taxi to runway ...

Just because the jets are 'readied' for emergency intercepts, there is absolutely no way that a jet would just take off as soon as the call is out; they must start their engines, perform their checks, taxi if necessary, and begin the take-off. Engine checks and calibration can take anywhere from 4-10 minutes, from what I understand, and taxi/takeoff could take from 5-15 minutes or more.

30 seconds isn't much anyway, and if you were to move (taxi) in a jet before engine checks you will have a drift on inertial navigation, which would feedback an improper position of your aircraft.

taxiing isnt what this discussion is about, its how long would the engines take to start up.

check the thread, ALOT of people are talking about taxiing, also

ets would be on a permanant state of readiness

what do you mean ?? they constantly have there engines on and ready ?? surely u cant mean that?

Does anybody read the whole thread? I don't think so. Do it please before giving a stupid statement or bring arguments against what we found out here, if you think all is wrong.

An aircraft is not a car where you can turn the keys to make it fully operational.

An aircraft is a very complex system, that has more than an engine and some bombs under the wings.

If you leave a jet in alert condition, it's fueled, armed and prepared for flight, but engines off.

If necessary it's possible to connect the aircraft to an external power supply to keep the electrical systems (for example the IRS and flight-computers) running, so that there is no need of an IRS-align. The engine can be started in 2 min. or less and Warm-up time is short for jet-enines. Checklists could be reduced to a minimum and the computers could be set-up with data before and then left on standby.

In this case maybe you are able to scramble in 3 min. But 30 secs is impossible!

Good point. Did not think about the fact of external power to keep the IRS/Flight Navigation/Etc. running on standby. On that case, the start up would be short due to not needing the IRS to calibrate and such, and it could take off very quickly (especially ala a hangar in parallel with the runway).

But, of course, that's still 2-4 minutes to run up the engine, and roughly another minute to actually get wheels-up and at altitude.

O.k. Even if engines were ready to go and the pilot didn't need to do several checks before taxiing and all that jazz, has anyone thought about the time it'd take the pilot to actually get inside the aircraft, close the cockpit and strap himself in?

30 seconds is a good compromise between gameplay and realism.

Yeah, the time to get inside the cockpit and attach the belts and so on takes a time too. I didn't include that in my calculation. Maybe in some case the pilots wait inside the cockpit to scramble.

Also CAS aircraft are not on scramble like this - just interceptors for emergency if the enemy has broken though the air defence line and no CAP is available.
CAS flight normaly patrol an area in the air until they are called in. Otherwise it's called a strike mission.

Are scrambles ment for the unexpectant?

ready to go doesnt mean on the runway, even if not in hangars, they wait in the apron, and even real scramble it would take 5 minutes 15-20 if you include the pilots being pulled out of bed, be glad it only takes you a grand total of 2. Unless an aircraft is expecting to take off they are not fueled, same goes for weapons, when pilots are scrambled, so are the crew that arm and fuel the ship, while the pilots are getting shoved into their flight suits, they're busy fueling and loading munitions. pre flight check, await go signal from the tower, and everything in between.

in response to Feuerwaffen: yes, a scramble is when you need to be in the air ASAP unexpectedly for any given reason, hijacked planes? incoming bogey? ICBM? a really big bird that showed up on radar and scared the **** out of the operator? who knows, they'll tell you when you're halfway down the runway.

That's only true in parts. Aircrafts normaly will be refueled to maximum after they landed. The reason is that in an empty fuel tank water from the air inside would condensate. If the engine gets water it will flame out.
There is a vent on the bottom of the fuel tank to get the water out of it (water is heavier than fuel, so it's on the bottom of the tank).
But to do this bofore scrambling would take additional time - so the jets are fueled right after landing usually.

it's to prevent stupid people from trying to move without the taxi... and like a few of you said, it is NOTHING... I start the acceleration (W) before I'm set up on the runway... do it right before you turn onto the runway...
