Topics

• Topic for future show.

1. Economic situation
2. Tech people compensation.
3. Are the best CEO’s psychopaths?

• Video Game writers in trouble?
• My Background in Aviation.

1. Commercial Pilot Airplane, Multi-Engine, Land and Sea. Glider, Hot Air Balloon, Flight Instructor, Aerobatic Flight Instructor. I have flown a glider aerobatic routine in both the U.S. and Canada.
2. While at MDA I worked on a computer flight dispatch system. Aides and FOCUS.
3. I have logged time in 737-200, 747-200, and DC-10 simulators.
4. I had the privilege of flying in the cockpit of many airliners before 9/11.

• Update on Air France Flight 447.

1. No Flight Recorders found.
2. French Nuclear Sub listening for the pings.
3. Fifty bodies found.
4. Broken bones indicate aircraft broke up in mid-air.
5. Pitot Tube changes.
6. Question about why the Flight recorders don’t float. Dan Van Hoy
7. ACARS (Aircraft Communications Addressing and Reporting Systems) data sent from flight 447.
8. Auto Pilot disengages.
9. Alternate Flight control laws kick in.
10. Air Data Inertial Reference Unit fails.
11. Standby Instrument System fails.
12. Two of the three FMC fail.
13. Aircraft depressurized. 40,000 ft. 63,000 ft.
14. ACARS is a commercial system. It was not designed by a Government agency.
15. ACARS automatically switches from land based ground stations to satellites to keep in constant communications.
16. ACARS sends out the position of the aircraft every ten minutes.
17. ATC does not do this.
18. ACARS is not certified by any government agency.
19. It is reported that the U.S. is asking for the ACARS data to be encrypted.

• Define some terms.

1. Stall…Angle of attack. Relative wind.
2. IAS…Indicated airspeed. Pressure at the pitot tube as compared to Static pressure port.
3. TAS…Corrected for altitude and temperture.
4. As you climb and hold IAS the TAS goes up.

• V-Speeds

1. Vmo Maximum operating speed.
2. Discuss how pitot tube fault could lead to exceeding this speed.
3. Vmmo Mach buffet speed.
4. Va Maneuvering speed.
5. Discuss how this might take the vertical fin off the airplane.
6. Vb maximum gust intensity…Maximum structural cruising speed.

• Takeoff V speeds.

1. Pilot Not Flying voice calls during takeoff.
2. V1…Committed to fly…If one engine quits you will continue. Before this you can stop in the length of the runway left.
3. Vr…Rotate…Lift the nose 10 to 11 degrees.
4. V2…TO safety speed…you can reach 35 ft. by the end of the runway.

• No talking while below 10,000 ft.
• Certification bottle necks.
• Fedex Trucks use digital communications. Aircraft use voice.
• Do we need to do a risk assessment study to determine which has the most risk…flying with old technology…or simplifying the certification system.
