FREEZE HORIZON- The time or point at which an aircraft's STA becomes fixed and no longer fluctuates with each radar update. This setting insures a constant time for each aircraft, necessary for the metering controller to plan his/her delay technique. This setting can be either in distance from the meter fix or a prescribed flying time to the meter fix. FREEZE SPEED PARAMETER- A speed adapted for each aircraft to determine fast and slow aircraft. Pilot/Controller Glossary Fast aircraft freeze on parameter FCLT and slow aircraft freeze on parameter MLDI. FRICTION MEASUREMENT- A measurement of the friction characteristics of the runway pavement surface using continuous self‐watering friction measurement equipment in accordance with the specifications, procedures and schedules contained in AC 150/5320-12, Measurement, Construction, and Maintenance of Skid Resistant Airport Pavement Surfaces. FSDO- (See FLIGHT STANDARDS DISTRICT OFFICE.) FSPD- (See FREEZE SPEED PARAMETER.) FSS- (See FLIGHT SERVICE STATION.) FUEL DUMPING- Airborne release of usable fuel. This does not include the dropping of fuel tanks. (See JETTISONING OF EXTERNAL STORES.) FUEL REMAINING- A phrase used by either pilots or controllers when relating to the fuel remaining on board until actual fuel exhaustion. When transmitting such information in response to either a controller question or pilot initiated cautionary advisory to air traffic control, pilots will state the APPROXIMATE NUMBER OF MINUTES the flight can continue with the fuel remaining. All reserve fuel SHOULD BE INCLUDED in the time stated, as should an allowance for established fuel gauge system error. FUEL SIPHONING- Unintentional release of fuel caused by overflow, puncture, loose cap, etc. FUEL VENTING- (See FUEL SIPHONING.) G GATE HOLD PROCEDURES-Procedures at selected airports to hold aircraft at the gate or other ground location whenever departure delays exceed or are anticipated to exceed 15 minutes. The sequence for departure will be maintained in accordance with initial call‐up unless modified by flow control restrictions. Pilots should monitor the ground control/clearance delivery frequency for engine start/taxi advisories or new proposed start/taxi time if the delay changes. |
