What is an Approach Ban?
When a country puts a limit on the visibility AND ceiling for the approach to commence before commencing the final approach segment.
Whats the difference between QNH and QNE
QNE is above TA
QNH is below TA
If you receive a QFE what is the procedure?
Respond but request QNH ( should be on request) Delta does not use QFE!
What terminology is used with ADS-B to show the controller has valid position?
Identified. Identification terminated is used when no longer in range
Chines flight level allocation scheme is found…
In the airway manual.
What is the Chinese Route Diversion procedure if unable to contact chinese controller.
Track right 30 degrees, parallel course at 5 NM climb or descend.
Define Class II navigation
Navigation that takes place outside of the standard range of VOR/VOR-DME/NDB
When flying over the middle east, what must civilian a/c do to identify themselves?
- Use transponder and weather radar at all times
- Actively monitor guard frequency
How does ICAO define mountainous area?
gain or loss of 3,000 ft within 10 NM
What defines a terrain box?
high terrain at or above 8,500 ft msl which prohibit a descent to 10,000 msl.
What altitude should you descend to if you cannot determine min altitude in terrain box?
FL250
How long are the passengers supplied O2
12 min
How many minutes prior to the EEP during ETOPs should you receive updated alternate wx?
45 min prior
ETOPS logbook must be signed off prior to ETOPS flight?
Yes
When should you refer to the airway manual for potential fuel freeze limitations?
when the sat -65C, polar routes.
What are your options to raise fuel temperature?
- Increase mach number
- change altitude to a warmer air mas
- change route to a warmer air mass
What is GOMEX?
Airspace above the Gulf of Mexico
How many LRNS required in GOMEX?
1
Optimum HF can vary with the sun angle. As a rule of thumb what frequencies are better with a lower sun angle vs a higher?
Low frequency = sun setting
High frequency = sun up
Takeoff weights above 300,000 lbs should be considered what?
Heavy
When must you fill out howgozit log?
When operating on or off airways in non-surveillance airspace
Where is the ICAO differences and special procedures located?
Jepp app, under “pubs”
When do you make a logbook entry for IRS drift?
IRS drift greater than 2 NM per hour and a/c operated in non-surveillance airspace more than one hour.
If your ETA is more than how many minutes in oceanic airspace ATC should be notified?
2 minutes.
Can you offset left of center line with SLOP?
No, only right
What transponder code should you set in oceanic non-surveilance airspace? What are the exceptions?
2000, Exceptions:
- North Atlantic High Level Airspace (Nat HLA), wait 30 min after entry before switching to 2000.
- In WATRS airspace. Reykajavik OCA is the same.
When must you monitor raw data?
When GPS is not functioning:
- Prior to descending below grid MORA, one pilot will manually tune each nav aid to confirm the proper inboud or outbound track
- When operating into or out of an SAQ, must monitor raw data below grid MORA
- At all other airports, after confirmation, both pilots may use FMS map mode for sit awareness.
*must remain alert to sudden map shifts, monitor raw data if this occurs until position can be verified. Do not use egpws.
When must you complete a SELCAL check?
- prior to entering airspace requiring two- way, long range ATC communications
- When changing frequencies within the same ATC sector
- When changing ATC sectors on the same frequency, unless ATC instructs the crew to “MONITOR”
What is SATCOM used for?
2 way telephone communication (expensive) and acars datalink.
RNP - 10 and RNP - 4 require what distance of lateral seperation?
10 = 50 nm and 4 = 30 nm (Tracking up to 4 nm for 95% of flight time)
What does PTAPTP stand for?
Position, Time, Altitude, Position ( next fix), Time ( next fix), position (name of following fix)
When will wpr reset not work?
outside of 100 nm abeam the original point.
How do you become familiar with political issues occurring in countries you may fly over?
- Deltanet corporate security web page
- U.S. State Department web site
If loss of cpdlc, data-link update who must you contact? If working, how quickly should you respond?
ATC and dispatch. try to respond within 60 sec with stby at a minimum
Ocean contigencies for emergency situations, how should you navigate?
5 nm offset to the right and descend below FL290 if needed. Offset +/- 500 ft if unable to contact ATC
Which way does the ITCZ shift in the summer and winter?
Shifts south in the winter and further north in the summer
What does GRID MORA provide?
No nav aid or signal coverage. does provide 1000 ft of terrain clearance and 2000 in mountainous areas
What does MEA mean?
Ensures acceptable navigational coverage and terrain clearance.
What does MOCA mean?
Lowest published altitude between radio fixes and meets alt clearance requirements and meets signal coverage within 22nm.
International fuel are…
Straight release, B043 and B044. Description listed in FOM.
What is the definition of ETOPS?
More than 60 min from adequate airport with 1 engine out.
What is considered an adequate airport?
- Sufficient in length and width
- able to accommodate the aircraft landing with 60 percent of the effective landing distance.
What is considered a suitable alternate airport?
- Same as adequate
- Also, meet wx min requirements
Two seperate ETOPS cruise limitations at what times?
120 min ETOPs and 180 min ETOPs
