Night Air Mail Light Beacons

As a little kid I heard about the light beacons used to guide the Air Mail flights across the United States in the 1920s.  But just a year or so ago I learned that the beacons also included a concrete arrow on the ground to point to the next beacon and that some of these concrete arrows still exist.  I have flown VFR across the US many times and was surprised that I had not heard of or seen any of them.  But just recently, on my cross-country from the west coast to the east, I randomly chose KGNT in New Mexico as KGNT mail beacon - 16a refueling stop.  KGNT (Grants-Milan Airport) sits at 6537′ just west of the 11,301′ Mt. Taylor.  I was thrilled to find a complete Airway Beacon Site that has been moved to this airport and restored by the Cibola County Historical Society.   The small FBO is a very friendly place and loaded with memorabilia.  The photo on the left is taken from the ramp looking at the FBO and you can see the beacon to the rear of the building.  The next photo is of the beacon and the generator shed along with the concrete arrow pointing to the next beacon station.  Also in the photo on the left there is a partially restored CAA Flight Service Station that was used during   DSC00670the era.  If you go to the Cibola web site you will find much more information on the beacons and their efforts to preserve this piece of aviation history.  This next two pictures are of a small memorial

Mountain Flying

I’ve been doing some mountain flight training in an area southwest of Carson City, NV.  Mountain flying in helicopters requires good performance planning as well as an understanding of the effects of wind, weather, and the of course the lack of O²!  I currently use the ForeFlight™ app on my iPad retina mini for flight planning, en route navigation, and situational awareness.  I’m a big fan of ForeFlight™; check out this screen shot.  foreflight

When you are in flight the symbol ForeFlight™ provides for your aircraft is an airplane, helicopter, or some other symbol (the symbol is user selectable).  I usually use a helicopter but in this case my position is just a blue dot.  This is because I’m not moving.  Yep, just landed at about 11,500′.  Depending on the source the highest airport in the world is in Tibet at about 14,219′ with a runway over 14,000 feet long.   But 11,500′ is still pretty high.  I have landed at higher elevations but this 11.5K spot is about the highest we can use in this area.

DSC00661Here is a photo of one of my passengers at 11,500′.  It was about -7 degrees at the time.  I like to use a mountain flying technique of approaching the landing site on the windward side.  This puts the helicopter in smoother up flowing air.  The up flow (updraft) requires less power.  I then make passes at 40 knots to discover which direction provides a headwind.  I let the aircraft crab into the wind and continue into the landing site all the while keeping power applied.  This technique allows the pilot to approach with power in a controlled manner while providing an escape route into the wind and up flow.  Great training and great fun!
