Abstract

Instrumentalno prilaženje definirano je načinom elektroničkog vođenja zrakoplova u horizontalnoj i vertikalnoj ravnini. Visina se u zrakoplovu standardno mjeri barometarskim visinomjerom. Temperatura zraka važan je čimbenik u određivanju visine leta koji nije kompenziran barometarskim visinomjerom. Kada je temperatura zraka manja od standardne vrijednosti, zrakoplov će biti niže nego što pokazuje visinomjer. Za određenu vrstu instrumentalnog prilaženja koristi se isključivo barometarski visinomjer kao izvor podataka o visini leta za proračun vertikalnog profila prilaženja. Stoga je u ovom radu objašnjen utjecaj temperature zraka na visinu leta, navedena je jednadžba za korekciju indicirane visine pri niskim temperaturama zraka te su razrađeni postupci koje posada zrakoplova mora poduzeti prilikom proračuna visina u prilaženju kako bi se osiguralo sigurno nadvišavanje prepreka.

Abstract (english)

Instrument approach is defined by the method of electronic guidance of an aircraft in the lateral and vertical modes. The altitude of the aircraft is usually measured by a barometric altimeter. Air temperature is an important factor in determining the aircraft’s altitude which is not compensated by the barometric altimeter. When the air temperature is lower than the standard value, the aircraft will be lower than indicated by the altimeter. For a specific type of instrument approach, the barometric altimeter is used exclusively as the altitude source for the calculation of the vertical approach profile. Therefore, this paper explains the influence of air temperature on altitude, states the equation for the correction of indicated altitude at low air temperatures and describes the procedures that the flight crew must perform when calculating altitudes during approach to ensure safe obstacle clearance.
