UteRC Night Fly Postponed to Saturday October 5, 2019

Oct 5 2019 5:00 pm

Hi All,

Bad weather on Sept. 28th caused a postponement of the Night Fly for a week to Oct. 5th. All the other details are the same. We will still have no Moon in the sky during the event so plan on flying in a totally black sky.

Our annual Night Fly will be at the club's Lake Point field beginning
at 5 pm. Steve Wilson will be grilling some goodies to be served about
6 pm. Bring a side dish to share. Be prepared for the cold that will
come quickly after the sun goes down.

Besides an early evening picnic and learning to fly in the dark, the purpose of this fun fly is to photograph the interesting light patterns the planes make at night.

Practice and check flights can be done as time permits as the sky
darkens on this Moonless night. Rig your planes with reliable colored
LED lights so you can keep track of the planes attitude in a
pitch-black sky. The more acrobatic maneuvers the plane does the
better the light pattern. But, if your lighting fails, you will not be
able to see the plane to fly and land it. About the only thing you can
do is shut off the throttle and give it a little bit of rudder to
maintain a gentle turn. An independent blinking light on the plane
will help you follow its path as it comes down and can help you find
it if the main lighting fails.

Sunset will be at 7:14, but the sky will not be dark enough until
8:46. Because of the long (20 seconds) exposures needed to capture
light trail patterns, the sky must be absolutely black. If you can see
the horizon to the west, it is not yet dark enough to photograph the
light trails.

One last tip: If you fly your plane away from the photographer, then
the entire light trail your plane makes can be captured by the camera.
If you fly to the camera, the trail is way, way too close to capture.

Good luck to all and I hope we can capture some interesting light
patterns in the sky this year.

See you there.
