QUIZ 3 - AIR NAV WEEK 8,9

What is Track Error

result of too little or too much WCA

What is TE expressed as?

Degrees or nm left or right of FPT

WCA > Drift

WCA too large

WCA < Drift

WCA too little

WCA = Drift

TE = 0

How to maintain correction for FPT & TMG?

Determine TMG

See how far you’ve wandered away (how much off track/degrees off track)

Turn so you’re going alongside path

Gently move along TMG (Intercept and maintain track)

What is 1:60 rule?

1 degree error over 60 nm = 1nm off track

Fomula for 1:60 rule?

Distance off track/Distance flown = TE (degrees)/60

Formula for CA?

Distance to go x CA = DOT x 60

Wave Characteristics depend on?

wavelength

frequency

energy of transmission

Radio Wave Propagation types?

attenuation - surface, atmosphere, ionosphere

building and obstacle reflections

static interference

refraction - coastal

DME formula

Altitude in ft/6000 = x NM over station

DME SRP

always difference of 63 Mhz between interrogation and transpondent frequencies

DME types

beacon saturation

station identification

range and coverage
