Night Flights Over City Lights
Nighttime approaches over the bright lights of large metropolitan areas offer visual orientation challenges that multiply if the area is unfamiliar, as discovered by this General Aviation pilot:
Got Oxygen?
There's the story about the little girl who misbehaved and was asked by her shocked mother, "Don't you have manners?!" "Yes m'am, I have em," she replied, "I just don't use em." That story came to mind when we read this First Officer's report to the ASRS:
According to the language of the FARs, oxygen masks should be "properly secured and sealed" not held to the face with one hand. If you've got masks, use em (properly).
Low Altitude Frights
A General Aviation pilot was taking a friend on a daytime sightseeing tour over a coastal harbor at 900 feet MSL. The area was well known for its high bird concentrations. The pilot had avoided hitting several birds early in the flight, according to his ASRS report, when luck suddenly ran out:
It felt as if someone had punched me in the face. After recovering my glasses, it took about five seconds to get control of the airplane. The altimeter read 900 feet, but I could see we were less than 200 feet AGL. For this reason I believed the onrush of air had caused a malfunction of the static system. This was further confirmed by the fact that my airspeed indicator was barely in the green arc, despite indications to the contrary, such as a GPS ground speed of 122 knots and a tachometer reading of 2300 RPM.
As a result of the airspeed indicator being unreliable, I felt a long runway was needed. I called Approach to get vectors to land at [airport ABC]... Approach suggested [airport XYZ], which was three minutes closer... I preferred a vector to ABC because I was more familiar with the obstacle clearances and runways at ABC. Holding a map and even changing radio frequencies was very difficult with all the wind in the cockpit. I was having difficulty keeping a steady altitude and heading, since my free hand was used to hold onto a piece of the windshield and loose maps were flying around the cockpit.
I had to enlist the help of my passenger, when the other 50% of the windshield was on the verge of giving way. She held onto the jagged piece for the duration of the flight. She was very calm and helpful. I had briefed her about her "duties in the cockpit" and what to do in case of an emergency. The tips about CRM from CALLBACK over the years had paid off in spades...
I would like to say that greater vigilance would have helped, but I'm not sure that's true, since I am very paranoid while flying over the harbor. I have always felt that any low altitude flight has a high level of risk in any aircraft. I am no longer taking passengers around the harbor for sightseeing.
This pilot demonstrated skill, perseverance, and solid resource management techniques in getting the aircraft under control and landing safely. We were most gratified to hear that lessons learned from CALLBACK gave an assist. Chapter 7, Section 4 of the Aeronautical Information Manual (AIM) is also recommended reading for information on bird strike hazards and risk reduction techniques.
Go Fly a Kite (Carefully!)
It may be tempting to think that aviation is all about airborne experiences, but a large number of aviation enthusiasts enjoy ground-based hobbies that involve moored (tethered) devices such as balloons and kites. An instrument rated pilot who was hosting a "kite party" describes a near encounter between a sports kite and a helicopter:
It would be a good idea for our reporter to brush up on the applicable regulations, too. FAR 101 prohibits the flying of moored kites more than 500 AGL and within 5 miles of the boundary of any airport. It also requires that kites flown between sunrise and sunset have colored pennants or streamers attached to the mooring lines at not more than 50-foot intervals, beginning at 150 feet above the surface of the ground and visible for at least one mile.
