RTP IFR theory

Question 1

For the purpose of flight preparation, what is the estimated time of use and aerodrome?

Answer 1

When planning for a destination alternate, the aerodrome must be suitable for an Estimated time of use (ETU) valid 30 min before ETA + 30 min after ETA.

Note: Isolated Aerodromes require a -30 + 60 min ETU validity.

See:
1. Part 121 CH4.05
Vol 6A

Question 2

What is the standard window for COBT

Answer 2

Arrivals: -5, + 15 min (5 min early or 15 min late)

Note: Perth has a COBT for departure:
-5 Minutes + 10 minutes

Question 3

When ATC allocates a waypoint crossing time, what time must the aircraft arrive at that waypoint?

Answer 3

On time or max 30 seconds early.

Question 4

What is the minimum obstacle clearance required when circling in a Cat C aircraft?

Answer 4

Cat C: Pilot should maintain a Min Obstacle Clearance of 400ft

Question 8

What is the circling radius to be used for a Cat C aircraft? Pans Ops (ICAO) and TERPS (FAA)

Answer 8

ICAO: 4.2 NM
FAA: 2.7 NM

OLD FAA: 1.7 NM

See FCTM Circling approaches & JEPP 4.16

Question 9

What are the requirements for conducting a visual approach by Day under IFR?

Answer 9

1. Within 30nm
2. In sight of ground or water
3. 5k vis or airport in sight.

Question 10

What are the requirements for conducting a visual approach at Night under IFR?

Answer 10

1. Within 30nm or being vectored by ATC (Above MVA)
2. In sight of ground or water
3. 5km visibility or airport in sight.

Jepp 1.9.3 Vis approaches

Note: Must stay 500ft above LCA STEP

Question 11

What is the maximum allowable in-flight difference between Captain and First Officer altitude displays for RVSM operations?

Answer 11

200 ft

See FCOM Limitations L.10.2

Question 12

Do Standby altimeters meet the accuracy requirements for RVSM airspace?

Answer 12

No

See FCOM Limitations L.10.2

Question 13

What is the Altimeter tolerance for IFR flight?

Answer 13

ONE Altimeter MUST read the nominated elevation to within 60 ft. If the second altimeter has an error up to a maximum of 75ft error, flight under the IFR to the first point of landing, where the accuracy of the altimeter can be re-checked, is approved. Only one check is allowed.

See Jepp Altimetry 1.1.2

Question 14

What are the maximum allowable on-the-ground altitude display differences for RVSM between F/O and CPT altimeter?

Answer 14

CL = 40ft

NG = 50ft

Question 15

How is visibility (RVR) determined during daytime at aerodromes without a weather service provided? (Vol6A 3.1.77)

Answer 15

Counting centre line markings visible forward from the flight deck. Centre line markings consist of a stripe and a gap with a combined overall length of between 50 and 75 metres. Assessments should be based on 50 metres spacing.

Question 16

How is visibility determined during night time at aerodromes without a weather service provided? (Vol6A 3.1.77)

Answer 16

RVR at night may be assessed by counting the runway edge lights. The spacing of runway lights is 60 metres for instrument runways.
