IFR Flashcards
What is a DME
Distance measuring equipment. The transmitter is on the aircraft and sends an SSR signal to a ground unit. It accurately and continuously measures slant range from the aircraft to the tuned ground station
ILS deviation formula
You’re 5 DME and the CDI reads 2 dots left
DME x dots x 50 = deviation in ft
5 x 2 x 50 = 500ft left of centreline
How many degrees is full CDI deflection on a VOR
10 degrees
How many degrees is full CDI deflection on a ILS
2.5 degrees
What is a VOR
Uses the phase difference in the variable and reference radio signals. Between 112Mhz and 117.95Mhz. It is used to obtain the aircraft direction from the VOR transmitter
How to follow the localizer needle instructions inbound and outbound
Inbound - follow the needle
Outbound - turn away from the needle
Glideslope correct altitude based off 3 degrees formula at 3DME and a threshold elevation of 200ft
Distance x 300 + Threshold elevation
3 x 300 + 200 = 1100ft
Rate of descent formula
G/S x 5 = ROD
Glideslope deviation formula
Full deflection
1/2 deflection
Full deflection
DME x 70ft = ft above or below
1/2 deflection
DME x 35ft = ft above or below
One the G1000 what type of navigation uses a magenta CDI
GPS
On the G1000 what source of navigation uses a green CDI
VOR and LOC
AUX chapter on the G1000 includes
GPS status, RAIM, timer, trip stats, programmed events
EIS on G1000 shows
Engine indications, landing gear position, electrical information, fuel,
What does the HDG key on Flight Director (FD) do
Captures and tracks the selected heading
What does the NAV key on the Flight Director (FD) do
Captures and tracks the selected navigation source. (VOR, LOC, FMS)
ALT key
Holds current selected altitude
VS key vertical speed
Can be used to hold current vertical speed or to select one in 100ft increments
FLC key (Flight Level change)
Holds the current IAS in a climb or descent to a selected altitude
How many vertical feet per mile on a standard 3 degree slope
300ft/nm
On the g1000 how do you find the Ann test key
Aux>system status>Ann test
Radio call to ch approach after T/O
CH Approach Frasca 44 passing (current altitude) climbing 3000ft (departure name) squeak code
Navaid tuning sequence
Tune frequency
Identify station (audio or visual)
Test
Set cdi bar on the intended track and bug the heading
