OFP Example and Decode
13.2
8.1.6.3

Question 2

NOTOC / LDF Location Coding

Answer 2

11-29 is FWD, 31-49 is AFT, and 50+ is BULK
0 is CABIN

13.8

Question 3

Runway Surface Condition Reports
- Layered Contaminates

Answer 3

16.1.2 / QRH-N

Question 4

WET ICE

Answer 4

Take-off on runways contaminated with WET ICE is prohibited. Landing is authorized for WET ICE only when using an upgraded runway condition code for landing performance (RWYCC > 0)

16.1.2.2

Question 5

CONTAMINATION COVERAGE
- Percentage

Answer 5

For a runway or runway segment to be reported wet and/or contaminated, the coverage must be greater than 25%.

16.1.2.3

Question 6

Cleared Width

Answer 6

• The usable surface has been cleared to a minimum of 50 feet (15m) on either side of centerline, and
• No Snowbanks, windrows, snowdrifts or wet ice contamination are present outside the cleared area and within 75 feet (23m) either side of centerline.
• Canadian RSC reports may indicate that the cleared width is offset from the centerline. Take-off and landing is prohibited for runways that have a cleared width not centered on the centerline.

16.1.2.5

Question 7

Downgrade – Take-off
- Active Weather Conditions

Answer 7

During active conditions, and the controlling condition is 1/8”, it is recommended that the flight crew downgrades the controlling condition by using a depth of 1/4” instead of 1/8”.

For any RWYCC downgrade to 1, use Ice to compute take-off performance irrespective of the contaminant type.

16.2.2.3

Question 8

Downgrade - Landing
- Active Weather Conditions

Answer 8

If a reported RCC value is associated with a depth of contamination (RCC 5 for snow or water less than 1/8”) during active conditions, consider downgrading to the RCC value associated with a greater depth.

When the runway is reported WET RCC 5 during periods of moderate or heavy rain, crews should consider using data for RCC 2.
