IRT Questions

Question 1

What time must you have filed a flight plan by?

Answer 1

at least 1 hour before off chocks time

Question 2

What time must you have entered the airway by?

Answer 2

+ or - 3 minutes of cleared time

Question 3

How early/late can you be before needing to refile the flight plan?

Answer 3

30 mins

Question 4

How do you join an airway if ‘cleared to join at’?

Answer 4

Hit airway at 90 degree angle, + or - 10nm from point to gain track

Question 5

How do you join an airway if you are ‘Cleared to join on track’?

Answer 5

Must be on track below airway, climb once join point underflown

Question 6

What does ‘join on track at ROLEX FL90’ mean as an airways clearance?

Answer 6

A join on track where the airspace steps down to the cleared FL rather than the aircraft being climbed up to the airway once join point overflown.

Question 7

Airways flight parameters (speed, AoB, turn anticipation)

Answer 7

Speed 0.65M, AoB 45 degrees (2.5nm turn radius), anticipation around 4nm for 90 degree turn

Question 8

Rate 1 Turn ‘rule of thumb’

Answer 8

1/10 TAS +7 = AoB required for rate 1 turn

Question 9

Course bar deviation increments (TAC/VOR, ILS)

Answer 9

TAC/VOR = 4 degrees, ILS = 1.25 degrees

Question 10

Altimeter temperature correction? When is it applied?

Answer 10

Applied if aerodrome temp <0 degrees. Correction = +4ft per 1000ft elevation per degree difference from ISA

Question 11

TACAN approach tolerances? (Arc limits, radial tolerance to continue from IF, max speed <10nm hold join, mad drift for hold to be flyable, deviation on descent from FAF)

Answer 11

Arc limits - + - 1nm
Radial tolerance to continue from IF - 5 degrees
Speed <10nm hold join - 230kts
Max drift for hold to be flyable - 10 degrees
Deviation on descent from FAF - Half scale deflection

Question 12

VMC conditions (>FL100, 3000, >3000)

Answer 12

> FL100: 1500m horiz, 1000ft vert, 8km vis

3000ft agl: 1500m horiz, 1000ft vert, 8km vis (5km if less than 250kts)

> 3000ft amsl: 1500m horiz, 1000ft vert, 8km vis

Question 13

Hawk T2 approach categories (normal, flapless)

Answer 13

Normal - C

Flapless - E

Question 14

CAS types (A-G)

Answer 14

A: Airways, TMAs (Heathrow, Birmingham, Manchester)
B: Not used in UK
C: Upper airspace (FL195-FL660)
D: CTRs, CTAs (e.g. Stansted, Glasgow, Gatwick
E: Belfast TMA, ATS routes in Scotland
F: Not used in UK
G: All remaining airspace below FL195
