Random Knowledge Flashcards
Are runway numbers True North or Magnetic North?
Magnetic North
What color are taxiway centerlines?
Yellow
What color are runway edge lights in the first half of the runway?
Runway edge lights are white, except on instrument runways yellow replaces white on the last 2,000 feet or half the runway length, whichever is less, to form a caution zone for landings.
What color is the beacon at a civilian lighted land airport?
Civilian land airport beacons are alternating white/green.
ILS Critical Area.
Are you legally required, with weather less than 800/2, to hold short of an ILS Critical Area?
7110.65 “ATC BIBLE” states ATC is supposed to issue a hold short of ILS critical area call when weather is less than 800/2.
3-7-5. PRECISION APPROACH CRITICAL
AREA
a. ILS critical area dimensions are described in
FAAO 6750.16, Siting Criteria for Instrument
Landing Systems. Aircraft and vehicle access to the ILS critical area must be controlled to ensure the integrity of ILS course signals whenever conditions are less than reported ceiling 800 feet or visibility less than 2 miles. Do not authorize vehicles/aircraft to operate in or over the critical area, except as specified in subpara a1, whenever an arriving aircraft is inside the ILS outer marker (OM)
or the fix used in lieu of the OM unless the arriving aircraft has reported the runway in sight or is circling to land on another runway.
PHRASEOLOGY-
HOLD SHORT OF (runway) ILS/MLS CRITICAL AREA.
1. LOCALIZER CRITICAL AREA
(a) Do not authorize vehicle or aircraft
operations in or over the area when an arriving
aircraft is inside the ILS OM or the fix used in lieu of the OM when conditions are less than reported ceiling 800 feet or visibility less than 2 miles, except:
(1) A preceding arriving aircraft on the
same or another runway that passes over or through the area while landing or exiting the runway.
(2) A preceding departing aircraft or
missed approach on the same or another runway that passes through or over the area.
(b) In addition to subpara a1(a), do not
authorize vehicles or aircraft operations in or over the area when an arriving aircraft is inside the middle marker when conditions are less than reported ceiling 200 feet or RVR 2,000 feet.
Engine Oil Quantities:
What is the total engine oil capacity in quarts?
How many quarts low are we allowed to be?
How many quarts are measured on the oil dipstick?
14 quarts total.
Allowed to be 4 quarts low.
5 quarts show on the dipstick.
What is the purpose of winglets?
Explain how they work..
Why don’t all new airplane’s have them?
Winglets help disturb wingtip vortices by having the high pressure air curl over and impact the winglets (a much smaller surface area) as opposed to the vertical portion of the wings that are creating more critical vertical lift. They are more effective at higher angles of attack such as take off/landing and high altitude cruise. The winglets do create a slight forward lift and extra drag and weight but their benefits overcome those.
The higher pressure creating upward lift moves towards the outside of the wings. Without the wingtips the air would continue its path and come up and over the wingtip. Lower angles of attack the air is able to move under the wing faster and less is pushed outside.
Dynamic High pressure lowers the static pressure of the air around the foil. So relatively speaking, high pressure is still lower pressure than the parcel of air around the aircraft. It’s a matter of where you point the center of pressure vector.
You’re sitting right seat in your friend’s Cessna Grand Caravan flying out of San Jose, California (KSJC). You call tower when you reach the departure runway and they tell you to “hold for release.” What does this mean?
When ATC says to hold for release, they are trying to find a time slot for you to enter the IFR system. This usually has to do with traffic management and weather issues.
You’re departing out of Catalina, California (KAVX). You called the FSS to get a relayed clearance from ATC. Your clearance void time is 1530Z and the current time is 1515Z. What is a clearance void time?
When departing out of non-towered fields, you are issued a clearance void time, where, if you haven’t departed (wheels up) by this time, you clearance is void. You then would be required to contact ATC for a new clearance to your destination.
You are enroute between Chicago O’Hare (KORD) and Champagne, IL (KCMI). At some point along your route, ATC asks you to hold at a fix. After their holding clearance, they say “Cessna 239NA, expect further clearance 1620Z, time now 1550Z.” What is the purpose of an EFC time?
When ATC tells you to hold, they issue you an EFC time for multiple reasons. it gives you an idea of how long you’re going to be holding and whether or not you will have to leave the hold and go to your alternate due to fuel constraints. Equally as important, it gives you a time to leave the hold in the event you find yourself in a lost communications situation.
You’re flying from Chicago O’Hare (KORD) to Newark, NJ (KEWR). You are given an EDCT time or an Expect Departure Clearance Time to Newark. Why does ATC issue these?
ATC will issue EDCT times to aircraft that are flying to airports located within high traffic density regions. This is to help with traffic management going into these airports/airspaces.
You’re headed to Dallas-Fort Worth (KDFW) from Miami, FL (KMIA). ATC asks you to proceed direct JRHED for the SEEVR FOUR arrival. Upon reaching JRHED, ATC says to descend via the SEEVER FOUR arrival and to contact regional approach on 125.025. What does “descend via” mean.
When ATC asks you to descend via a STAR or climb via a SID, they want you to follow the procedure as published. Meaning, follow the lateral track outlined in the procedure, as well as meet all altitude and speed restrictions to the bottom altitude.
ATC says “Ronin ___, at pilots discretion, descend and maintain 17,000. Maintain 200 knots in the transition.” So…when does ATC want you at 200 knots? What do they mean by “transition”?
ATC wants you to maintain 300 knots when you pass through the crossover altitude. This is the altitude where a specific indicated airspeed turns into a specific mach number (during a climb) and vise versa in a descent. When your airspeed transitions over to KIAS, maintain 300 knots.
