Tech Flashcards
If you have a yaw damper failure do you think you should slow down or speed up?
Slow down. A failed yaw damper can lead to Dutch roll. Higher speeds would exaggerate the effect.
Explain a dutch roll
- Out of phase turn where airplane rolls in one direction and yaws in the opposite

What are the potential threats of a short taxi?
- Being rushed to complete before take off checks.
- Failing to to notify flight attendants of take off.
- Engine warmup time
Can you walk me through descent planning using 3-1 method?
What speed and airspeed is this predicated on?
Altitude you need to lose multiplied by 3. 30,000 descend to 20,000 = 10 x 3 = 30 miles prior start descent assuming no winds.
(0) Fl310 and 310 knots. Decent to 9000 and 240kts how far would you start out to get down and slow down.
** based on a normal jet airplane, idle thrust,
speed Mach 0.74 to 0.78, and vertical speed of 1,800–2,200

Is ceiling or visibility required on an approach?
Visibility
Can you walk me through your companys V1 abort procedure?
Past v1 proceed with the takeoff. Run qrh. Return to departure airport.
What would you do if after a windshear go around, you only have 75 minutes remaining of fuel?
- 2 in 2 out get info from dispatch about alternates. Once info in received make a choice of alternates and make sure FO is comfortable with choice
- If other aircraft go around behind you proceed to an alternate
What do you need if you’re vectored off a STAR
You need an altitude assignment. An ATC vector off of a SID or STAR cancels that procedure and they must assign an altitude. FAA Order 7110.65Z.
What does the center line lighting on the last 3000ft of the runway look like?
AIM 2-1-5: “…the runway centerline lights are white until the last 3,000 feet of the runway. The white lights begin to alternate with red for the next 2,000 feet, and for the last 1,000 feet of the runway, all centerline lights are red.”
What is TEM?
Process of managing operational threats and than errors.
Look up SPirit definition
How would you handle a yaw damper issue?
I’m unfamiliar with that checklist so I’d hand the controls and radios to the FO if I was PF, I’d note our fuel on board, and then we’d run the checklist as a team. Once that’s complete, we’d at least let dispatch and maintenance know, we may need to consult with them depending on any operational limitations. ATC and passengers probably don’t need to know, I may let the FAs know just in case they need to let me know about oscillations felt in the cabin.
Why does V1 change if the runway is wet?
The decision speed will be lower, giving the aircraft more distance to stop on a wet runway.
What is rejected takeoff criteria?
Until 80 knots, the decision is weighted towards rejection. Above 80 knots, the decision is weighted towards continuing, with three big exceptions being engine failure, fire, or aircraft is unsafe to fly. Above V1, as long as the airplane can fly, we’re going flying.
What is the radius of the MSA?
25nm
What is a standard climb?
Standard IFR climb gradient is 200 feet per nautical mile.
What are holding speed restrictions?
AIM 5-3-8(2): Maximum holding speeds: At or below 6,000 ft. 200 KIAS. 6,001 to 14,000 ft. 230 KIAS. Above 14,000 ft 265 KIAS
What is the difference between flyby and flyover waypoints?
Fly-by waypoints are used when an aircraft should begin a turn to the next course prior to reaching the waypoint separating the two route segments. This is known as turn anticipation. A fly-over waypoint is a waypoint that must be crossed vertically by an aircraft.
What is the reciprocal of 266?
086
Dumping fuel at 1500pounds/hour, how long to dump 16500 pounds?
Getting into the weeds is absolutely incorrect here. Most important factor in interviews same as checkrides. Listen to the question!!! It specifically asks how long to DUMP. 11 hrs. Next question! Dont overthink things. If they ask how long to be 16,500 lbs lighter, now thats a different story where burn comes into play. Details on question wording are important. Attention to detail is an important trait! (May 28, 2019 - Marc M.)
How long to travel 90nm, with 190TAS and 60kts headwind?
- 41.5 min
- solve as a proportion.
190-60= 130 knots groundspeed
130kts/60min = 90nm/X 90 x 60 divided by 130 = X 41.5 min.
When should you start down from FL350 to cross fix at 12,000ft
- 69 miles out
- Altitude to lose x 3. The answer is 69nm
No published hold on the missed, what entry, speed, leg length would you use?
Right turns. 0 to 6000’ 200knots, 6-14000 230 knots, above 14k 265 knots. Below 14000’ 1 min, above 14k; 1.5 min legs.
What is an MSA?
The Minimum Sector Altitude (MSA) is the lowest altitude which may be used which will provide a minimum clearance of 300 m (1 000 ft) above all objects located in the area contained within a sector of a circle of 46 km (25 NM) radius.
Define MEA and a MOCA?
MEA is the minimum altitude that guarantees: 1) 2-way ATC communication. 2) Navaid coverage along the route section. 3) 1000’ / 2000’ in mountainous terrain clearance. ** “Mountainous” = greater than 3000’ per 10 NM elevation gain. On the Jepp charts, such as a STAR, the first (sometimes only) number between route fixes is the MEA. MOCA: min altitude that guarantees VOR reception within 22 NM (25 SM) from the beacon; 1000’ clearance when terrain is 5000’ MSL –has nothing to do with mountainous, unlike MEA. On a STAR, this is the number between route fixes that has a “T” next to it, i.e. 4000T = MOCA of 4000’ MSL. Boom.
Above answer was cut short. For MOCA, it’s 1000’ when terrain is 5000 ft and less. 2000’ when 5001 ft. (November 27, 2018 - Sean H.)
(1) Min Enroute Altitude-Altitude on airway that provides terrain clearance(1000/2000’) and navigation signal coverage. MOCA- Min Obstruction Clearance Altitude- Provides terrain clearance(10000/2000’) while only providing nav signal within 22 miles of the VOR.
(0) In the first answer about MOCA, it has the same obstacle clearance requirements as MEAs, which is to say 1000’ and then 2000’ in mountainous terrain as per the described definition, but a communication limit of 22nm. A Grid MORA is the one that has the requirement for 1000’ at 5000’ and below and 2000’ at 5001’ and above.
Why is localizer more sensitive on a back-course? On a back course approach, why do we put in the front course
- Reverse sensing. 2. Greater sensitivity due to the fact that the Localizer antenna is closer to the airplane during the back course approach.

Which runways can you cross when cleared to taxi to a runway?
Only the runways which were you cleared to cross.
When would you want two alternates?
(6) Destination and first alternate marginal weather conditions. Or 3585 exemption used, two alternates needed.
(3) “Marginal Weather” definition and the conditions under which a second alternate must be designated must be clearly stated in the Part 121 Operator’s GOM (FAA Order 8900.1).
(1) Marginal weather- forecast within 100ft, 1/2 sm of minimums
When is an alternate airport required?
(4) 1,2,3 Rule. Within +/- 1 hr of ETA, if ceiling or vis below 2000’/3SM
(4) Be careful with these answers. Some are listing MILITARY alternate reqs. Part 121 reqs = 1,2,3 rule to list an alternate and weather required at the alternate (with one nav facility providing a straight-in precision, non-precision, or circling manueuver from the IAP) = Add 400 ft to the CAT 1 HAA/HAT and add 1 sm to CAT 1 landing mins; (with 2 nav facilities with different suitable runways) = add 200 ft to the higher CAT 1 HAA/HAT and 1/2 sm to the highest CAT 1 landing minimum of the two approaches (can mix and match).
(3) Confusing answers, hopefully this is more clear-1) for dispatch purposes- You need to have an alternate when the Wx at the destination is below 123 rule2) to use ____ airport as an alternate on your flight plan, Wx at ETA must be above- if it has a precision approach- 600ft ceiling, 2sm vis non-precision approach- 800ft, 2sm
(1) 123 rule is for destination. Alternate airport is at or above landing mins for that airport in that companies ops specs. (121.625)
(1) Also, you need an alternate if there is no published instrument approach at your filed destination.
What are the requirements for a takeoff alternate?
Must be within 1 hr, calm winds, single engine
When would you need a takeoff alternate?
8) Weather below landing minimums at departure airport.
(1) When VISIBILITY at departure time is less than landing minimums for the airport, but greater than takeoff minimums.
(1) § 121.617 Alternate airport for departure. (a) If the weather conditions at the airport of takeoff are below the landing minimums in the certificate holder’s operations specifications for that airport, no person may dispatch or release an aircraft from that airport unless the dispatch or flight release specifies an alternate airport located within the following distances from the airport of takeoff: (1) Aircraft having two engines. Not more than one hour from the departure airport at normal cruising speed in still air with one engine inoperative. (2) Aircraft having three or more engines. Not more than two hours from the departure airport at normal cruising speed in still air with one engine inoperative. (b) For the purpose of paragraph (a) of this section, the alternate airport weather conditions must meet the requirements of the certificate holder’s operations specifications. (c) No person may dispatch or release an aircraft from an airport unless he lists each required alternate airport in the dispatch or flight release.
