Never done in micro, but couple times have done night landings in Bliks with car lights & candles.
Candles in 2 litre coke bottles (secured with some sand) are great, but need to be preparred beforehand. We have 2 dozen or so on standby in hangar for emergencies. (We have landed a lear with these a couple times on mercy flights as well)
Car lights - 3 cars is ideal.
2 at threshold one on each side of runway with brake lights on - Brights down the runway showing sides.
1 with brake lights on at end of runway - no headlights.
Technique which works for me.... (in blik)
I fly with Taxi light on for oukes on ground to follow my progess, but with landing light off as you often tend to fly into the light and bend the U/C (Deer in the headlamps type scenario) I have seen trike at night (on groud) with lights on and it is very bright and does not help a huge amount to see where you going. I would turn them off:shock:
First pass (or as many as it takes to get comfy) I do inspection to get used to sensation, height, wind etc (very different - See FF's comments regarding depth etc) at safe altitude (50-100ft).
Second pass land deeper than normal (so you don't land on car roof) and slow as possible. In the bilks we set up for full flap almost hanging on the prop incase you get it wrong, you should be able to walk away from it and in most cases (unless very unlucky) use the aerie again....
as foward speed is slow as possible. (Assume trike would be similar)
PS
Why no night flying allowed in micro's (trike & 3 axis)? (excuse ignorance?)
