Q

When shall a SVFR not be permitted?

A

Never at night in the UK.

Other states permit it but is not permissible in UK. UK on request, must have min 3km vis, on execution must have min 1.5km vis

Q

What is relative airflow?

A

The direction of the airflow with respect to the wing direction is known as relative airflow. Lift acts 90 degrees to the RAF.

Q

What is total reaction?

A

The resultant of all aerodynamic forces acting on an aerofoil.

E.g. when an AC moves forward, thrust is required to overcome drag, and create a large enough pressure differential on the aerofoil to produce lift. So the total reaction of forward movement of an increase in thrust is a combination of lift and drag.

Q

what is the boundary layer, transition and separation point?

A

Referring to aerofoil where boundary layer is the layer between is the laminar flow and free flow air above.
Transition point is where the laminar flow has lost so much of its energy it’s starting to become turbulent.
Separation point is where laminar flow has now detached from the aerofoil and static pressure is high

Q

What is interference drag?

A

A type of parasite drag. Interference drag describes specifically the drag caused by the mixing of airflow streamlines e.g. the airflow from the wing and the fuselage. The engine pylon and the wing.
Anything which has a junction.

Q

What is a chord line and chord length?

A

Chord line is the imaginary line drawn from TE to LE. The length of this imaginary line is chord length.

Q

What is mean aerodynamic chord?

A

Chord is also used to describe width as well as length (chord length). In a platform rectangular wing, the MAC = chord. But with tapered and different shaped wings the average chord is calculated and determined as the mean aerodynamic chord (MAC).

Pitching moments of AC acts on the aerodynamic centre of the MAC

Q

Difference between MAC and COP?

A

While both are found in the aerofoil, MAC refers to the point in which all pitching moments act through, while COP refers to the point in which lift acts through.

COP is the average location of all pressures acting upon a body through a fluid.

Q

What is zero lift drag?

A

Aka profile or form drag. Profile drag is the drag caused by the separation of the boundary layer and the wake caused by the separation.

Therefore this would only occur if the AC was moving through a fluid. Note this type of drag does not relate to lift at all so the question is confusing!

Q

What is lift dependent drag?

A

Aka Induced drag. As question suggests, this is a type of drag that is induced by lift, and at low speeds. Also induced vortices at wing tip.

Q

What is adverse px gradient?

A

This is when static pressure increases in the direction of flow. This is not ideal on a wing due to separation point of laminar flow, which would lead to stall. Th faster the RAF moves, the lower the pressure.

Q

Aircraft lights?

Study These Flashcards
A

Red (L) & green (R) = 110 degrees
White (rear) = 2x70 =140 degrees

24
Q

Lighting heights?

Study These Flashcards
A

Obstacles: equal or more than 150m (492ft) med intensity red lights at top and at equal intermediate levels not exceeding 52m.

On airport: frangible and no more than 350mm (0.35m/35cm) above the surface

25
When do we switch from FL to Alt?
Transition level This is the lowest FL before changing to QNH
26
RWY lighting?
CL - 300m (1000ft) steady red lights. Then from 300 to 900m (600m/2000ft in length) alternating red and white. Edge = 600m (2000ft or midway of runway if less than 1850m) yellow and then white to the TD threshold
27
Types of drag?
Induced and parasite Details on others cards
28
COG?
Centre of gravity is a theoretical point where all the weight is considered to be concentrated, and dictates where the AC would balance if suspended. COG needs to fall within the flight envelope to ensure flight stability, control and safety. COG = moment/mass
29
TORA
The length of rwy sfc avail during ground run of the TO. This can include displaced threshold but never stopway.
30
TODA
Includes the TORA + clearway, all within the airport boundary to allow safe climb to 50ft
31
ASDA
TORA + stopway
32
LDA
Rwy surface available for landing
33
SF?
General safety factor: TO - 1.33 Ldg - 1.43 Wet Ldg only - 1.15 Snow - TO + Ldg = 1.25
34
CAT I minima?

Interesting facts about Logan?
Q2 2025 Most punctual airline for UK arrivals and depts published by CAA with 86% of flights arriving on time, beating out Virgin and Eurowings in 2nd and 3rd. No 2 on the Which next short haul budget airline in the UK. Odd to be in this list as not budget nor short haul. Regional. Just behind Jet2 which is completely different set up. UK’s biggest regional airline offering more UK destinations than any other airline. 2 world records - world’s shortest commercial flight (Westray and Papa Westray, Orkney) and only scheduled beach rwy (Barra, Outer Hebrides) Hydro-electric modification of Islander set to be certified in 2026 and inaugural flight in 2027 from Kirkwall. Loganair have their own registered tartan. Hence the tartan tail. The lifeline routes of NHS patients from ABZ to the Shetlands and Orkneys, or IOM to LPL. Direct routes to LHR from Derry, Dundee, IOM, Kirkwall, Sumburgh - confirming Logan’s belief in connecting communities to main hubs/cities.
41
Why Logan?
Pastie route to NQY. PSO routes Lifeline routes from Kirkwall, Sumburgh and IOM. Oil and gas contracts from ABZ/LSI, Royal Mail and freight
42
Why did you leave TUI?
43
What do you know about the fleet?
Approx 35 aircrafts. Twotters based GLA (multi crew), no Cc Islander in KOI (SP), no CC ERJ 145 - NCL, EDI, GLA, ABZ, Derry, soon to add SOU ATR45 500 - INV, ABZ - PAX - mostly for oil and gas contractors 600 - EDI, GLA - PAX ATR72 - 500: GLA, freighter 600 - EDI, GLA, ABZ, IOM - is workhorse and PAX. Only 1 with 2xCC Differences of 4 variants is self study. Main AC differences is flap settings and no. Of PAX and CC Investment in hydro-electric and fully electric aircrafts. Former close to certification 2026, while latter a few years off still.
44
Structure of Logan?
Logan ran by board overseen by Chairman. Ops side CEO Luke Farajallah. UK director and accountable manager Natalie Bush, who I will sit under as pilots and training department will sit under her remit.
45
How have you been flexible?
46
Purpose of SOPs?
Reduce risk and add SF. Safest conduct for AC. Better monitor as PM. Emergency situation don’t waste time talking about what we as crew will do and who does what.
47
Importance of being on time?
48
What would you do if wx below minima at your destination?
49
How would you deal with a colleague who breaks the rules?
50
A CC member seems flustered during a turnaround. How would you approach the situation?
51
What attributes do you have that make you a good fit for Logan?
52
What do you do in your spare time away from flying?
53
When have you shown good customer service?
54
How can a first officer give good CS?
Uniform Cordial Talking to them in terminal, waving to kids PA Say goodbye after flight As a FI SP have to give safety briefings but do that in a humorous way to lighten the mood and also more likely to remember it.
55
What are Logan’s values?
Leadership Ownership Gratitude Accountable Nimble Authentic Innovative Resilience Vision - making regional travel simple, enjoyable and sustainable Mission - connecting regions of UK with purpose and confidence
56
Cat IIIC minima?
No DH, No RVR
