Q

LAAS/GAAS Range?

A

19nm or 30km

25
Q

Rnav P2 Sidelobe Suppression

A

64.8 Degrees

27
Q

Second conversions… ms and uS

A

ms = 1/1000 (1 x10-4)

uS = 1/100,000 (1x10-6)

28
Q

DME Delay in response?

A

50uS

29
Q

Power required to double range?

A

4x (22) Power

16x (42) Power for Primary Radar (due to return)

(Inverse Square Law)

30
Q

MLS Lateral approach zone?

A

+ or - 40 degrees from centre-line

20NM out

31
Q

Why is Mode S Required for TCAS II

A

To provide a datalink for coordination of evasive manoeuvres between aircraft

32
Q

Using Baro input to a RAIM GPSS system does what to the number of sats required?

A

Reduces by 1

33
Q

Atomic Clocks in Galileo?

A

Rubidium and Passive Hydrogen Maser Clocks

34
Q

Ellipsoid in Galileo?

A

ETRS-89

35
Q

Quadrantal Error (NDB reception)

A

Due to re-radiation of signal from Aircraft structure. Most at 45 and 135 degrees each side (Quadrants!)

36
Q

Full scale deflection of ILS Glideslope Indicator

A

0.7 Degrees

37
Q

RNAV/RNP 10, RNP 4 and RNP 2 used for?
