AD 3 Heliports

Question 12

What is AIP amendments?

Answer 12

Permanent changes to the AIP as AIP amendments. These are amended or reissued as necessary to keep them current.

Question 13

What is AIP supplements?

Answer 13

AIP supplements contain temporary changes of long duration (three months or longer) and information of short duration which contains extensive text and/or graphics.

Question 14

What is a NOTAM?

Answer 14

NOTAM stands for “Notice To AirMen”, and must be issued quickly and efficiently without extensive text.

A NOTAM is issued whenever the information is:

• Temporary in nature and of short lasting
• Operationally significant and is permanent
• Short-notice temporary changes of long duration.

Question 15

What are the NOTAM prefixes?

Answer 15

-NOTAMN: New information
- NOTAMR: Replacing a previous a NOTAM
- NOTAMC: Cancelling a previously issued NOTAM

Question 16

What is a SNOWTAM?

Answer 16

A SNOWTAM provides information concerning snow, ice and standing water on aerodrome pavements.

Question 17

What is the maximum validity of a SNOWTAM?

Answer 17

8 hours

Question 18

When should a new SNOWTAM be issued?

Answer 18

New SNOWTAMs must be issued whenever there is a significant change in conditions. The following changes to runway conditions are considered significant when:

• A change in the coefficient of friction of about 0.05
• Changes in depth of deposit greater than the following;
  
  • 20mm for dry snow
  • 10mm for wet snow
  • 3mm for slush
• A change in the available length or width of a runway of 10 per cent or more
• Any change in the type of deposit, or its extent of coverage, which requires reclassification in Items F or T of the SNOWTAM
• When critical snow banks exist on one or both sides of the runway, any change in the height or distance from centre line
• Any change in the conspicuity of runway lighting caused by obscuring of the lights
• Any other conditions known to be significant according to experience or local circumstances

Question 19

How do you read a SNOWTAM?

Answer 19

1. Time and date
2. RWY Designation
3. RWY condition code x/x/x (every third of the RWY)
4. The prosentage of a third covered by whether x/x/x
5. Depth per third in mm x/x/x
6. Contents of the coverage x/x/x

F.eks:

02170055 09L 5/5/4 100/100/100 NR/03/03 WET/WET SNOW/COMPACTED SNOW

(The SNOWTAM will always start with the RWY with the lowest designation number)

Question 20

What does RCAM stand for?

Answer 20

Runway Condition Assessment Matrix

Question 21

What is an ASHTAM?

Answer 21

ASHTAMs provide information concerning operationally significant changes in volcanic activity.

Question 22

What are different alert colors of an ASHTAM?

Answer 22

Red alert: Eruption is forecasted to be imminent with significant emission of ash into the atmosphere OR eruption underway with significant emission of ash into the atmosphere.

Orange alert: Heightened unrest with increased likelihood of eruption OR eruption is underway, with no, or minor, ash emission. Ash up to but not included FL 250.

Yellow alerts: Signs of elevated unrest above known background levels OR after a change from a higher level of alert, volcanic activity has decreased significantly, but it monitored for possible renewed increase.

Green: Normal, non-eruptive state OR after a high alert level, activities considered to have ceased, and the volcano has returned to its normal, non-eruptive state.
