OK, From a ground crew perspective, here's what a typical air-show mission would entail.
While the Pilot checks the weather and deals with his flight-plan (dealing with air-show organizers and schedules and the like) the ground crew preps the airplane (Fuel, arranging for ground support equipment like a starter unit, etc.)
30-45 Minutes before scheduled take-off, the Pilot arrives at the aircraft, reviews the forms and performs a "walk-around inspection" making sure that all of the ground safety equipment is removed and the ground cew hasn't missed anything obvious.
10-15 minutes before "engine start" the pilot get into the cockpit and the ground crew assists him in securing his harness to the Ejection seat.
The ground crew applies ground power from the starting unit and the pilot runs through his pre-start checklist to make sure all of the switches are set properly and the computers and other electronics are all working properly.
When he's ready to start the engine(s) he uses the ground intercom or hand signals to ask for "Starter Air" -- on a two engine fighter like the F-15, it would be "Air on number two" to start the right or #2 engine first. (most jet Fighters don't have onboard starters and need compressed air from an outside source to drive small starter turbine to start the engines.) Engines are started from right to left because the boarding steps (and way out of the aircraft) are on the left side.
Once the external air source and starter turbine get the engine up to about thirty percent RPM, the pilot hits the ignition button and watches the RPM and EGT (Exhaust gas temperature) closely until the engine lights and he can call or signal for "Air Off." for a two engine aircraft, He waits for the external air source to be moved to the other engine and repeats the process.
Once all engines are running, he calls for ground power and external air to be removed an begins his post-start checklist. That includes checking hydraulic systems pressure, Oil pressure, Internal Electrical power, and rechecking the computer and electronics to make sure they're working properly on internal power.
Working with the ground crew, he'll check the flight control surfaces, speed brakes, and other (mostly hydraulically activated) systems.
When the ground checks are complete, he'll contact Ground Control and report he's ready to taxi. When he gets clearance to taxi, he'll inform the ground crew and the crew chief will disconnect his ground intercom cable and move out infront of the aircarft to marshal him out of the parking spot while the assistant crew chief buttons up the last few access panels and gets ready to pull the chocks.
When every thing is ready, the crew chief will signall "Chocks out" to the assistant crew chief and as soon as the chocks are pulled, he'll signal your pilot "power up" and then then "come forward." Wen the aircraft is clear of theparking spot, the Crew Cheif will signal a turn to the taxiway and give a salute to signal that the pilot is on his own (or to turn him over to the next marshaller in line, in some cases.)
The pilot willl stay in contact with Ground Control while taxiing to the end of the runway. If the airshow is at a military base or has a heavy militarypresence, there will be an "EOR Check" crew waiting for him there to do one final check of the aircraft and remove any last minute safety devices -- like arming pins for the jettison charges in exernal fuel tank pylons. (If there is no EOR crew, those last minute pins would be pulled at the parking spot.)
Once the EOR check is done, he'll taxi into postion and be handed over to the Tower by Ground Control. When the Tower gives him clearance, he'll taxi onto the runway, Stand on the brakes, push the engines to full power, do one last check of the engine indications at high power and release the brakes.
If the take-off is part of his airshow display, he'll hold the plane on the ground until he nears "show center" and then pull back on the stick for a max-power climb and go straight into his planned aerobatics display. Otherwise, he'll go somewhere away from the show site and orbit for a while until he's cleared into the show airspace for his display.
Often, military airshow participants will take off from their home base, fly to a holding area and check in with the airshow controllers from there, fly the demonstration or fly-by and return to home base without ever actually being "at" the airshow -- in the sense of being on the ground there where he can mingle with the crowds and sign autographs. This is especially true when the Airshow is at a small airport and there is a military base close by. (Is your fictional airshow even at n airport or airbase -- some of the bigger airshows are actually held over the beach or a lake with no ground displays available; there's a big annual airshow over Miami Beach and one over Lake Erie that are flown from several surrounding airports and military bases.)
Once he's through with the display, he'll land and taxi to a "de-arm" area (if there was an EOR check crew when he took off) and get the arming pins reinstalled. He'll check back in with Ground control for permission to taxi back to his parking spot where he'll follow the ground cew's marshalling signals back into his parkng spot.
The ground crew will chock the aircraft and signal him when it's safe to kill the engine(s).
He'll have a post-flight checklist to go through and a post-fight walk-around. Then he'll do a "maintenance debriefing" either at the aircraft with the crewchief if he's at a civilian airport or at a maintenace debriefing office if he's at a military base -- maintenance debrief includes documenting the aircraft forms on how long he flew, and any problems he might have had with the aircraft. It's not likely that for an airshow he would have to document any "expenditures" like weapons, flares or chaff but that would be part of a normal maintenance debrief.
Once he's done with the mainenance debrief, he'd head back to operations/life-support to turn in his helmet and other gear and do an oprations debrief -- for an airshow, things like recording his flight-time in his log book and dealing with any problems he may have had with control agencies would be the extent of an operational debrief.
Depending on where he's flying from, most of the pre-flight and post-flight stuf would be dealing with "Transient Maintenance," "Base Operations" and people he doesn't know -- if he's flying from his home base, he'd be dealing with "Squadron Maintenance" and "Squadron Ops" and people he knows and trusts. Eventually, he'll have to deal with his Squadron maintenance and operations people, too.
