C) MSL pressure using the average surface temperature over the last 12 hours

D) MSL pressure uses the average temperature and lapse rate at sea level.

From the Ground Up - Atmospheric Pressure

The pressure of the atmosphere at any point is due to the weight of overlying air. Pressure at the surface of the earth is usually measured by the mercury barometer and is expressed in inches of mercury ( "Hg).

STATION PRESSURE

Station pressure is the actual atmospheric pressure at the elevation of the observing station. It is, in other words, the actual weight of a column of air extending up from the station level to the outer limit of the atmosphere. The value is determined directly from the mercury barometer at the observing station.

For example: The weight of the atmosphere decreases with altitude, the atmospheric pressure reading at a station at 5.000 feet elevation will be less than that at a station at 1,000 feet and still less than that at a station at sea level.

MEAN SEA LEVEL PRESSURE

To have a consistent record of the distribution of atmospheric pressure, it is necessary to reduce the station pressures to a common level. This standard is called mean sea level (MSL) pressure. The reduction to MSL pressure involves adding to the station pressure the weight of an imaginary column of air extending from the station level down to mean sea level. In determining MSL pressure, local temperature must be taken into account. The temperature value is based on the average of the surface temperatures at the time of observation and for 12 hours before the time of observation. Mean sea level pressure is expressed in hectopascals.

ALTIMETER SETTING

To make an altimeter in an airplane correctly read the true height above mean sea level, it must be set to a standard atmospheric pressure. This pressure reading is called the altimeter setting. It differs slightly from the mean sea level pressure.

In reducing station pressure to sea level pressure for altimeter setting purposes, the standard sea level temperature of l S'C and the standard lapse rate of 1.98·C per 1,000 feet is used in computing the equivalents.

When correctly set, the altimeter will then read the true elevation of the airport at which the airplane is parked. If a pilot does not know the altimeter setting but does know the elevation of the airport at which the airplane is parked, he/SHE can dial in the correct elevation and get also the correct altimeter setting.

Altimeter setting is reported in inches of mercury.

A pressure expressed as 29.92 inches of mercury is equivalent to 1013.2 hectopascals.

78. What is the principal of operation of a Distance Measuring Equipment (DME)?

A) Paired pulses are sent out from the aircraft and are received by a ground station. The ground station then transmits paired pulses back to the aircraft on a different frequency. The time required for this signal exchange is translated into distance.

B) DME works by using triangulation from a GNSS system.

C) A laser accurately measures the distance between the aircraft and the ground station.

D) A radar signal is sent out from the aircraft and are bounced back from the surface of the earth. The time difference is measured as distance.

AIM COM 4.7 Distance Measuring Equipment (DME)

Distance measuring equipment (DME) functions by means of two-way transmissions of signals between the aircraft and the DME site. Paired pulses at a specific spacing are sent out from the aircraft and are received by the ground station. The ground station then transmits paired pulses back to the aircraft on a different frequency. The time required for this signal exchange is measured in the airborne DME unit and is translated into distance (nautical mile [NM]) from the aircraft to the ground station. Distance information received from DME is slant range distance and not actual horizontal distance. Accuracy of the DME system is within ±0.5 NM or three percent of the distance, whichever is greater.

DME is collocated with most Canadian VHF omnidirectional range (VOR) installations (VOR/DME) and with many instrument landing system (ILS) and localizers (LOCs). In some cases, DME are also collocated with non-directional beacons (NDBs) to provide improved navigation capability.

The DME operates in the UHF band and therefore is limited to line-of-sight reception with a range similar to that of a VOR. The receiving equipment in most aircraft provide automatic DME selection through a coupled VOR/ILS receiver.

Distance information from a Tactical Air Navigation aid (TACAN) facility can be obtained by selecting the appropriate paired VOR frequency. (In that case, only DME information is being received; any apparent radial information must be ignored.)

The DME slant range error is the greatest when the airplane is at a high altitude close to or over the ground station. Moreover, slant range error also affects groundspeed and time-to-staion displays when you are close to the station.

AIM COM 4.8 TACTICAL AIR NAVIGATION (TACAN)

Tactical air navigation aid (TACAN) is a navigation aid (NAVAID) used primarily by the military for en route, non-precision approaches (NPAs) and other military applications. It provides azimuth in the form of radials and slant distance in nautical miles (NM) from the ground station. The system operates in the ultrahigh frequency (UHF) range with the frequencies identified by channel number.

TACAN users may obtain distance information from a distance measuring equipment (DME) that is paired with the VHF omnidirectional range (VOR). This TACAN paired channel number is published in the Canada Flight Supplement (CFS) for every VOR/DME facility.

CAUTION:
Only DME information is being received by the TACAN avionics. Any apparent radial information obtained through the TACAN avionics from a VOR/DME facility can only be false signals.

In a VOR, full scale deflection is 10°.

In an ILS, full scale deflection in the localiser is 2.5°.

In an ILS, full scale deflection in the glidepath is 0.7°.

Remember you can only get to half full scale deflection before you must initiate a go around.
