IFR

Question 1

WHEN TO CONDUCT A MISSED APPROACH

Answer 1

(So Not Visual ROFL)

• Straight-in landing cannot be effected and a circling approach can not be made under the conditions, equal to, or better than, those specified for circling
• Not visual when you reach the DA/RA height or MAP
• RAIM warning or loss of RAIM after the IAF
• Outside tolerance during the final segment
• Failure of aid or suspect aid and below MSA
• Loss of visual reference during circling

Question 2

WHEN CAN AN AIRCRAFT BE FLOWN BELOW LSALT?

Answer 2

(Don’t Venture In Too Close)

• DME GPS Arrival
• Vectored by Radar
• Instrument Approach
• Thirty Miles by Day, Clear of Cloud, 5km Vis, in sight of ground or water
• Circling area by night or 5nm on PAPI / VASIS, 7nm on PAPI / VASIS if the runway has an ILS approach and 10nm if established not below on slope on an ILS
• On departure on climb to LSALT

Question 3

WHAT ARE THE GPS MODES AND SCALING

Answer 3

En-Route: 2nm Scaling
Terminal: (becomes active within 30nm of destination) 1nm Scaling
Approach: (becomes active by the FAF on a GPS approach) Scales from 0.3 to 0.06nm throughout an approach
Terminal and Approach modes only available on setup approach’s

Question 4

FORMULA FOR AMENDING MISSED APPROACH WHEN UNABLE TO ACHIEVE CLIMB GRADIENT

Answer 4

n = c - ( c (x / y))

n = height to add to published MDA
c = climb height from published MDA to TOC MAP
x = actual ROC or % gradient
y = required ROC or % gradient

Question 5

WHEN MAY A PILOT DESCEND BELOW THE CIRCLING MDA?

Answer 5

• Circling must have been included in your last IPC
• Must be within the circling area (Cat B: 2.66nm)
• Satisfied you have the required visibility as published on plate
• You have the runway approach environment in sight
• Able to fly the rest of the flight path without excessive rates of descent or erratic manoeuvres
• Maintain visual contact with the runway
• You must not descend until you have intercepted your normal approach path
