DEF

Specified period of time to which the conditions stated in a weather forecast refer.

CONT

The Costello Geomagnetic Activity Index model ... is a neural network algorithm that was trained on the response of the Kp geomagnetic activity index to solar wind parameters. The model takes the most recent two hours of solar wind data and returns a 3-hour activity index prediction in units of Kp. The valid time of the prediction is indicated on the output graphics by horizontal bars.

CONT

Guide to the Regional [Weather] Forecast Maps... The "Forecast Period" gives the 24-hour time span for which the plotted data are valid.

CONT

... Weather Forecasting System.... The operational run schedule is listed in the table below. Each run is identified by three characters followed by the forecast length in hours. The first character is the model identification, and the next two digits are the initial hour. As an example G00+48h means a model "G" analysis at 00 UTC followed by a 48 hours forecast.

Record 4 1998-05-11

English

Subject field(s)
  • Air Traffic Control
DEF

The number of international passengers that arrive on scheduled/charter flights during a one hour period. The hour is determined to represent the typical heavy traffic for which a facility is designed. [Canada Customs. "Land Border Facilities Design Guide".]

CONT

The demand during the peak hours is used to determine facility size. The FAA [Federal Aviation Administration] has design parameters to determine Typical Peak Hour Passengers.

CONT

... facility requirements are defined by peak period throughput, and mainly by that in the "typical peak hour".... The list below includes items which may require to be forecast.... Typical peak hour aircraft movements and throughput of passengers, cargo and mail, preferably categorized by arrivals and departures as well as combined(the typical peak hour may occur at different times for each item and categorization).

OBS

The PPHP for a specific site must be obtained from the airport operator.

Key term(s)
  • typical peak hour passenger
  • planning peak hour passenger

French

Domaine(s)
  • Circulation et trafic aériens
CONT

[...] les installations et services nécessaires sont définis par les mouvements de pointe et, surtout, par le trafic pendant l'«heure de pointe type». [...] La liste ci-dessous comprend des éléments qui peuvent nécessiter des prévisions. [...] Mouvements aériens et trafic de passagers, de fret et de poste de l'heure de pointe type, subdivisés de préférence en arrivées et en départs, et également tout ce trafic combiné [...]

OBS

Selon Mme Johanne Ostiguy, surveillante des services de rédaction du Bureau de la sécurité des transports du Canada, l'expression «Peak Hour Passengers» se traduit par «écoulement des voyageurs (des passagers) aux heures de pointe». L'expression tirée du document de l'OACI nous paraît nettement préférable.
