The FAA started issuing revised flight departure times to airlines Tuesday afternoon after an approximately two-hour "ground stop"’ halted all flights to and from Chicago's two airports because of smoke in an air traffic radar facility serving northeastern Illinois, airline officials said.

BERGERON- FINDEISEN:

ON OF THINGS I ENCOUNTER FOR FIRST TIME, AND I DON'T KNOW BEFORE, SO I DECIDE TO SHARE WITH YOU...

The Bergeron- Findeisen (ice crystal) process is based on the fact that maximum vapour pressure is higher over a water surface than over an ice surface.

WHAT'S THIS MEAN:

The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron and W. Findeisen), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient v***r pressure falls between the saturation v***r pressure over water and the saturation v***r pressure over ice. The saturation v***r pressure over water is greater than the saturation v***r pressure over ice (at the same temperature) creating a subsaturated environment for liquid water but a supersaturated environment for ice. This results in rapid ev***ration of liquid water and rapid ice crystal growth through v***r deposition. If the number density of ice is small compared to liquid water, the ice crystals can grow large enough to fall out of the cloud, melting into rain drops if lower level temperatures are warm enough.

Flying near power lines
Main power lines are easy to see, but when flying in their vicinity you must take the time to look for what is really there and then use safe procedures.
Remember, the human eye is limited, so if the background landscape does not provide sufficient contrast then you will not see a wire or cable. Although hydro structures are big and generally quite visible, a hidden danger exists in the wires
around them.

The figure shown above emphasizes this point. The main conductor cluster is made up of several heavy wires. These heavy, sagging conductors are about two inches in diameter, and very visible, so they tend to distract one from seeing the guard
or lightning protection wires, which are of much smaller diameter.
Guard wires do not sag the way the main conductors do and are difficult to pick out event in good visibility.
The only way to be safe is to avoid the span portion of the line and always cross at a tower, maintaining a safe altitude, with as much clearance as possible.
• When following power lines, remain on the right hand side relative to your direction of flight and watch for cross lines and guy cables.
• Expect radio and electrical interference in the vicinity of power lines.
• For operational low flying, do an overflight and map check first.
• Leave yourself and “out”—cross at 45 degrees to the line.
• Reduce speed in low visibility (for VFR—5000 m visibility; clear of cloud; 165 kt max.).

The Procedures for Air Navigation Services — Aircraft Operations (PANS-OPS) consists of two volumes as follows:
Volume I — Flight Procedures
Volume II — Construction of Visual and Instrument Flight Procedures

The division of the PANS-OPS into the two volumes was accomplished in 1979 as a result of an extensive amendment to the obstacle clearance criteria and the construction of approach-to-land procedures . Prior to 1979, all PANS-OPS material was contained in a single document. Table A shows the origin of amendments
together with a list of the principal subjects involved and the dates on which the PANS-OPS and the amendments were approved by the Council and when they became applicable.

Volume I — Flight Procedures describes operational procedures recommended for the guidance of flight crew and flight operations personnel. It also outlines the various parameters on which the criteria in Volume II are based so as to illustrate the need to adhere strictly to the published procedures in order to achieve and maintain an
acceptable level of safety in operations.

Volume II — Construction of Visual and Instrument Flight Procedures is intended for the guidance of procedures specialists and describes the essential areas and obstacle clearance requirements for the achievement of safe, regular instrument flight operations. It provides the basic guidelines to States, and those operators and organizations producing instrument flight charts that will result in uniform practices at all aerodromes where instrument flight procedures are carried out.

When you receive a clearance to taxi to a point beyond a runway, this clearance does not automatically include the authorization to cross that runway. Each taxi clearance beyond a runway shall contain an explicit clearance to cross the runway or an instruction to hold short of that runway.
