Oh... little late.

Er, we have a squadron going, for over a year now; Thursdays are flight night. Problem is just that noone bothers showing up.

Did a spot of flying today though, basically a Lolwaffle night. Perhaps more is in store.

And since we might actually get somewhere with it now, I plan to expand on this thread as much as is needed. Starting with another start-up guide, since aparently the one above is too difficult to digest. Which means, pictures!

It's quick and dirty, but it's really all you need to do.
-----

Basic electrical power
1. battery on
2. inverter to standby
3. enable boost pumps
4. turn on APU
5. wait for APU to come to 100% RPM
6. turn on APU generator

Avionics
1. turn on EGI and CDU
2. CMSP to standby, enable switches
3. arm ejection seat
4. turn on the radios (lower-right knob to TR for 2x VHF, lower-left knob to BOTH for UHF)
5. turn on radar altimeter
6. enable SAS channels
7. enable CICU, JTRS and IFFCC
8. enable anti-skid
9. uncage SAI
10. turn on MFDs

(yeah I kinda swapped 7 and 8...)

Engine start
It's an automated affair: move the throttle from its indent to IDLE position. If you have something like the Warthog controller you can physically do this, but for most you will either need to map a function to your controller or simply use the keyboard shortcuts: Right Alt + Home and Right Ctrl + Home.

You start the engines one by one, waiting for the engine start cycle light on the caution panel (on its top-left) to extinguish in between. You can not start them both at the same time.

Engine generators and APU shutdown
1. enable the engine generators
- (master caution will sound and the APU generator light on the caution panel will flash)
2. disable APU generator
- (master caution silences, light stops flashing)
3. disable APU

Do not disable the APU generator before enabling the engine generators. The interupt in electrical power will screw up CDU alignment. It's fairly easy to fix if you're familiar with it, but it's something you'll want to avoid... I forget this all the time.

INS alignment and EAC arming
This is where most people become confused. When you power up the navigation systems, it starts a procedure to align them. This takes time, and is required to fully complete if you wish to arm the enhanced attitude control system. EAC provides for the stabilization feature of the gun (PAC) and autopilot. Neither will function without it.

This is what you're looking for:

Note the flashing message at the top and the timer (T= 4.0). If the message is present but not flashing, you only have partial alignment, which is not enough for EAC. You can monitor the timer line to check progress; full alignment is at T= 4.0, confirmed by the flashing message at the top.

When you have full alignment, press the button next to NAV to switch the system from alignment to navigation mode.

Next, switch navigation to EGI:

And then enable EAC:

DTS upload
Simples: hit LOAD ALL:

The display will change to indicate it is loading:

Note that the circles at the other functions disapeared while an asterisk apeared next to the selected function. It will change back to the first example once it is finished.

Cutting corners
You don't have to go through all this one by one; some things can be done simultaneously. For example, I start the left engine right after enabling the APU generator, power up all the electronics, load DTS after turning on the MFDs and then start the right engine. While the right engine starts and the INS aligns further, I go rumaging through DSMS to configure weapon profiles and settings and whatever else needs to be tinkered with.

Point being, you don't have to wait on anything: by the time you're done setting things up INS will be aligned and the engines started.

Final checks
Enable nose wheel steering before taxiing. It's rather tricky without.

Set flaps for take-off, and close the canopy, enable your air supply and pitot heat:

(set barometric pressure for the altimeter. It is given with take-off clearance, so you'll need to tune VHF AM to the airfield you're at)

In flight
Enable master arm, laser and TGP (you could include TGP in avionics). Set CMSP knob to desired mode. Have fun.

Afterthoughts
Set weapons to safe and CMSP to standby before landing. Disable pitot heat after landing. Set T/O trim before your next take-off.
