IFR Minima

Question 1

Take off minima IFR

Answer 1

RVR 500m, the aircraft flight manual restricts us to this so it cannot be reduced!.

In theory in other aircraft the RVR could be reduced to 400m under the following conditions:
In the day time RVR 400m runway edge lights or centre line lights.
At night time at least runway end lights and edge lights or end lights and centre line lights.

Question 2

Landing minima IFR

Answer 2

Single Crew 800m

Can be reduced below 800m for the following conditions:

1. An RVR of less than 800m can be used for Cat 1 approaches provided by any of the following is used at least down to the applicable DH:
   • A suitable autopilot coupled to an /ILS/MLS/GLS/GBAS
   • Approved HUDLS including where appropriate, enhanced vision system or equivalent approved system which is not published as restricted.
2. Where Touch down zone lights and or centre line lights are not available, then the RVR should be no less than 600m (EPLL?)
3. An RVR less than 800m can be used for APV operations when using runways with FALS RTZL RCLL when using HUDLS or equivalent approved system, or when conducting a coupled approach if decision height is above or equal to 250ft.

Question 3

Stabilisation criteria 3D

Answer 3

An IFR approach must be stabilised by 1000ft AGL
Speeds:
Normal -5kt + 5kt 
Single engine -5kt +10kt 
Turbulent conditions -10 + 10kt
Lateral 1  dot 
Vertical 1 dot
No more than 15 degrees angle of bank 
Gear and flaps as briefed 
No more than 1000ftpm (unless briefed)
Throttle not idle

Question 4

Stabilisation Criteria 2D

Answer 4

An IFR approach must be stabilised by 1000ft or 500ft in VMC.
Speeds: 
Normal +5kt/-5kt
OEI -5kt/+10kt
Turbulent conditions -10kt + 10kt
Half Scale CDI or 5 degrees RMI
Vertical +-75ft
Bank 15 degrees
Throttle not idle 
Gear and flaps as briefed

Question 5

Take off alternate

Answer 5

Take off alternate
A take-off alternate aerodrome should be specified in the operational flight plan if either the meteorological conditions at the departure aerodrome are below the applicable landing minima or in case it should not be possible to return to the departure aerodrome for some other reason. Ceiling will be taken into account when the approach is non precision.

The take off alternate must be within 1 hour cruise with one engine inoperative.

Question 6

Minimum Autopilot engage height

Answer 6

400ft

Question 7

Minimum height before making a turn

Answer 7

400ft

Question 8

What altitude do you change the outbound time in a hold

Answer 8

14000ft

Question 9

Angle of bank for a holding

Answer 9

3 degrees per second or 25 degrees angle of bank whichever requires the lesser bank

Question 10

Angle of bank calculations

Answer 10

TAS/10 + 7 or TAS x 15 Percent

Question 11

Non precision approach criteria

Answer 11

MDH when flying CDFA not lower than 250ft, RVR not less than 750m.

Question 12

Isolated aerodrome

Answer 12

An aerodrome can be classed as isolated when the fuel required exceeds:

For piston engines 45mins + 15% trip time or 2 hours which ever requires less fuel.

For turbine 2 hours fuel above destination including final reserve. (1.5 hours without reserve)

Question 13

Adequate aerodromes

Answer 13

Sufficient runway 
Navigation equipment
Lighting 
Fire and rescue 
Air traffic service 
Weather reports

Question 14

When is a missed approach mandatory?

Answer 14

1. The stabilisation criteria is not met.
2. The approach becomes unstable below the required point.
3. At DA the visual reference is not in sight.
4. Below DA visual reference is lost.
5. If ATC request so.
6. In case of a runway incursion.
7. When the pilot not flying suggests a go around.

Question 15

Destination alternate aerodromes

Answer 15

The weather needs to be at or above the planning minima, one hour before/ one hour after ETA.
The destination alternate needs to be reached within one engine cruise speed within one hour from the destination.
