The skip distance of HF-transmission will increase with:

• Higher frequency and lower position of the reflecting ionospheric layer.

• Lower frequency and higher position of the reflecting ionospheric layer.

• Higher frequency and higher position of the reflecting ionospheric layer.

• Lower frequency and lower position of the reflecting ionospheric layer.

When an operator increases the range on a radar-display, in general

• Both the PRF and the pulse length increase

• The PRF becomes higher and the pulse length smaller

• Both the PRF and the pulse length decrease

• The PRF becomes lower and the pulse length larger

VDF is the abbreviation for:

• Very High Frequency Deviation Finding Station

• VDF Direction Finder

• Very Direct Finder

• VHF Direction Finder

In an ILS system, concerning the Glide Path principle of operation, the difference in depth of modulation (DDM):

1. Decrease with angular displacement below the Glide Path.

2. Increase with angular displacement above the Glide Path.

3. Decrease with angular displacement above the Glide Path.

4. Increase with angular displacement below the Glide Path.

The combination regrouping all the correct statements is:

• 2 and 3.

• 1 and 4.

• 1 and 3.

• 2 and 4.

What is the colour sequence when passing over an Outer, Middle and Inner Marker beacon?

• Amber - White - Green

• Blue - Green - White

• Blue - Amber - White

• White - Amber - Blue

What is true about the FMC databases

• The navigation database contains the company's cost index strategy

• The data includes SIDs, STARS and runway approaches.

• The data can not be customized for the specific airline operations.

• Performance database contains aeronautical information for the planned area of operations of the aircraft.

Concerning the wave propagation in the ionosphere, we denote three layers. Those three layers are

• D, E and F layers and their depth does not vary with time

• D, E and F layers and their depth varies with time

• A, C and E layers with equal depth

• A, B and C layers and their depth varies with time

In which frequency band does an ILS glide slope transmit?

• EHF

• SHF

• UHF

• VHF

• MSAS, GAGAN, GALILEO, WAAS.

• NAVSTAR, WAAS, INDIAN INSS, GALILEO

An aircraft at FL 340 is tracking towards a DME with a 250 kt ground speed. What range and ground speed will be indicated 2 minute before flying overhead?

• 6nm <250kt

• 7nm <250kt

• 5nm <250kt

• 7nm>250kt
