1 Flashcards
Theoretical range of VHF?
= Square root of 1.5x Reciever alt in feet
What is ILS sensitivity?
- 1 dot = 1/2 degree course deviation
- full scale = 2.5 degree off centre
- glideslope = 0.7 either side, 1.5 full
ALTS definitions
- height = AGL
- Elevation = on ground above MSL
- Altitude - AMSL
- Absolute ALT = actual height of aircraft above surface of earth
- True Alt = height above MSL (indicated ALT corrected for temp)
- FL = 1013.25
Altimeter error for IFR?
- If error <60ft but >75ft can depart but needs second check. If still more than 60ft its US
- 2 alts - one must be within 60ft
second more than 75 - no go
above 60 but less than 75, needs another test
second check above 60, no go
Airspeed corrections
ICET - its pretty cool drink
instrument, pressure, compressibility, density
what is Vmo?
maximum operating for specific ALT,
changes with change in alt
What is Mmo?
- maximum Mach number for altitude
Descend below MDA?
“VMC”
- visual reference maintained
- minima requirements adhered to
- continuously in a position where a landing can be made with normal; rates of decent
IFR A/C departing without forecast?
- pilot satisfied they can return to land within one hour
- can obtain destination and alternate forecast within 30 mins of departure
ALT - Aids?
PVT
- one approach or ALT
CHR/RPT
- pilot must be able to suffer failure of 1 aid and still conduct a IAP
Descent below MSA/LSALT
Dont vector in very close D - DME/GNSS approach V - Vectors I - IAP V - Visual by day C - Climb or take off
When is a MAPt conducted?
so not visual rofl
So - straight in approach cannot be conducted and minima doesn't allow for circling Not Visual - not visual at DA MDA R - Raim lost O - outside of tolerance F - failure of an aid L - lost visual while circling
ALT - electric lighting
Alt must be provided for any aerodrome with electric lighting unless
- standby power available and indicated on ERSA
- responsible person
Equipement for IFR (standard)
9 items ASI ALT AH x2 VSI T/S DG Compass clock OAT
IFR equipment stuff (++)
- assigned altitude indicator (Class C)
- Mode C transponder
- Autopilot in hdg and alt mode
- no need if dual control and second pilot
- if U/S can be operated for 3 days including day it went U/S
RAIM for ENR, TERM and APP/LNAV
ENR - 2nm
TERM - 1nm (switches within 30nm)
APP/LNAV - 0.3nm
