I was doing a PPL a while ago, stopped by my future wife,
did solo already, always remember the briefing between pilots
just before T/O,
"if we have an engine failure during take off, if there are sufficient R/W, we stop, if we do not have enough R/W, keep going, do not consider coming
back to the R/W unless we are at least 500 feet..."
Also one of the lesson I enjoyed most is emergency landings... and I somehow remembered the brief to passengers.. it goes like this...
"unfortunately we have encountered engine problem and have to perform an emergency landing, your pilot has been trained for this so please be calm. Please ensure your seatbelt is fasterned and ensure that all lose items are secured, also remove any sharp objects on you

, after we land please leave the A/C immediately and assemble near the back of the A/C"
doing this while
1. Spotting a landing place
2. Controling the plane at best glide speed
3. Making mayday calls
4. trying to restart engine !
