Always check fuel tank selector valve positions with a torch at night.
Never let the presence of equipment you don't know how to use change your decision making - especially Wx Radar - assume its not there.
If you are flying with a trainee who is under stress toward the end of a flight, have a quiet word during approach about how slamming full brakes on touchdown is not required.
Don't fly in IMC/night unless you yourself have calculated/extracted from chart the LSALTs.
