SICP

Question 1

What should records of training include

Answer 1

who conducted the training, who maintains the training records, what training is provided

Question 2

When is equipment preparation

Answer 2

30-60 days. everything should be inspected, prepared, ordered, and inventoried

Question 3

Snow Control Center (SCC)

Answer 3

a centralized facility for coordinating all snow and ice control activities

one purpose is to inform air carrier and the ATCT of expected runway opening and closing times and serve as the prime source for the dissemination of field condition information

At minimum will perform the following functions: manage snow clearing operations, serve as the prime source for initiating FICONS, closure, openings ect; informing ATCT, air carries, air taxies, and other users of airport conditions; issuing NOTAMS; any additional function the SCC performs at the airport

Question 4

Airfield Clearing priorities

Answer 4

Priority 1: most critical portions of the aircraft movement area and supporting facilities

Priority 2: less importance than 1

Priority 3: not essential to flight operations

Question 5

Acceptable contaminants to most jet aircraft manuals

Answer 5

landing with no more than one inch of snow, slush, or standing water
takeoff with no more than 1/2 in accumulation

all snow and ice and slush should be removed as expeditiously as possible so as to maintain runways, high speed turnoffs, and taxiways in a “no worse than wet” condition

Question 6

Contaminant Clearance times

Answer 6

check notebook

based on the ability of the maintenance staff and equipment to clear on inch of snow weighing up to 25lbs per cubic foot from the primary runways. Normal trigger point for commencement of removal is prior to 1in of dry snow. If wet snow, prior to 1/2in

Question 7

Eutectic Temperature or Composition

Answer 7

the temperature that is the limit of freezing point depression, equivalent to the lowest temperature that the chemical will melt ice, occurs with a specific amount of chemical

Question 8

RCAM Runway Condition Assessment Matrix

Answer 8

tool by which an airport operator will assess a runway when contaminants are present

Question 9

Slippery when wet

Answer 9

it is only reported when a pavement maintenance evaluation indicates the average Mu value on the wet pavement surface is below the minimum friction level classification specified in the RCAM table. RWY CC 3/3/3

Question 10

Snowbanks

Answer 10

Check notebook for snowbank profiles

Question 11

FAA sand

Answer 11

Sieve Designation Percent by Weight Passing
8 100
30 20-50
80 0-2

Question 12

what deicing and anti-icing materials are for use

Answer 12

airside Urea, sodium acetate and sodium formate, potassium acetate and formate, alternative or hybrid deicers, sand

Question 13

Pavement surface condition sensing instruments serve what three functions

Answer 13

to provide a precise measure of the pavement temperature, to indicate the presence of water, ice, or other contaminants, to transmit this information to the snow control center for incorporation into the decision-making process to control contaminants

Question 14

What are the three steps to determine runway conditions

Answer 14

runway condition code applicability: 25% rule

apply assessment criteria: look at contaminants and get CC

validating runway condition codes: makes sure the CC feels right

Question 15

When can you upgrade a 0 or 1 CC

Answer 15

if judgments says its better, you are getting Mu values of 40 or more. You must continue to continually monitor and can not improve it past code 3

Question 16

when should a friction assessment be conducted

Answer 16

when the central portion of the runway is contaminated 500ft or more

after any type of snow removal or chemicals application

immediately following any aircraft incident or accident on the runway

or any additional triggers an airport any have locally

Question 17

What are the requirements for closures

Answer 17

runways receiving a Nil breaking assessment

After two NIL reports from pilots, an assessment must occur prior to the next operation on that surface

whenever a surface becomes Nil

Question 18

central de-icing facilities

Answer 18

at terminals or apron areas

Question 19

remote de-icing facilities

Answer 19

located on taxiways or near departure runways

Question 20

how to determine what snow removal equipment is required per AC 150/5220-20, Airport snow and ice control equipment

Answer 20

Step 1: determine the total square footage of priority 1. The snow removal equipment is based on the annual operations at an airport and the amount of Priority 1 surface area to be cleared in a specific amount of time

Step 2: determining the airfield clearance time establishes a specified clearance time for the Priority 1 areas the be cleared for a range of annual airplane operations. equipment should clear 1in of falling snow weighing up to 25lb/ft3 within a reasonable time frame

Question 21

What are the mechanical methods for snow removal

Answer 21

rotary plows, displacement plows, broom or snow sweepers, material spreaders

Question 22

Rotary plows

Answer 22

or snow blower, cast heavy concentrations of plowed snow away from airport operational areas

Question 23

Displacement plows

Answer 23

designed to quickly move snow across the blade of the plow. the cutting edge shears snow, lifts and casts it to dislodge snow to the side of the cleared path. classified by length of cutting edge

Question 24

broom or snow sweepers

Answer 24

used to clean up the residue left on the pavement surface by a plow or snow blower. also used to sweep and clean debris from airport operational areas

Question 25

material spreader

Answer 25

provides a continuous, unrestricted, accurately metered flow of sand and solid or liquid deicers or anti-icers to a pavement surface. a spreader unit consist of a material storage compartment, pre-wetting mechanism, a feed mechanism, a metering device, and a distribution mechanism
