IVC check was fine, I didn't need to restart between IVC check and take off.
When I got into the pit I was on VHF 2 and could hear my flight but they could not hear me. I could see the VHF2 lighting up but no one could hear me. I'll check frequency but I've not touched the frequency
It became clear that I had spawned behind a flight other than my own, so I took off on my own. I intended to catch up to my flight using the datalink but I got a bit tumbleweed and neglected to raise my gear.
I got a warning for my nosewheel steering, tried to raise my gear at this point but the green lights remained on. So I declared emergency landing and used chat to say I was RTB.
On final the landing gear lights went out so I checked my speed and judging it against my fuel flow I believed my gear were down so I decided to try as ejecting would lose the airframe.
On landing the plane pitched forward heavily and started sliding sideways down the runway so I ejected.
I put it down to experience, would like to jump on and check IVC in game before another proper mission though.
