IRT Questions

Question 1

What is RTR and how does it affect your instrument approach?

Answer 1

Radar Termination Range – the point at which your radar service terminates. On an approach, you continue after RTR until your MAPt,at Valley RTR is 0.5nm before MAPt, so fly to the MAPt using nav kit, or if that has failed, fly at your MDH for 10 seconds, then action a missed approach.

Question 2

What category of approach does the Hawk T2 fly when configured? When Flapless?

Answer 2

C, or E when flapless.

Question 3

Identify the symbols for IAF/FAF on the TAP.

Answer 3

As per TAP.

Question 4

What do the Bold numbers indicate on the IAM?

Answer 4

IAM is based on QNH.

Question 5

What angle of bank should you fly when joining the TACAN hold? How does this change when established?

Answer 5

30 degrees, then 25 degrees when established.

Question 6

What are the azimuth/glidepath limits on an ILS approach?

Answer 6

Half scale deflection.

Question 7

What is the tolerance on the azimuth on a TACAN approach?

Answer 7

Within 5 degrees of published tracks.

Question 8

What is the tolerance on MDH for your rating?

Answer 8

+100ft, -0ft.

Question 9

Describe an on track join of an airway.

Answer 9

Any description based on entering the airway having established the airway centreline at the reporting point.

Question 10

Describe a join at a point of an airway.

Answer 10

Any description based on entering the airway at right angles to the airway reporting point (cutting the corner as required).

Question 11

What rule of thumb can you use to work out the anticipation in NM required for a 90 degree turn in the airways structure?

Answer 11

Move the decimal point of your mach number one to the right, and subtract 2 from the first digit, i.e. 0.65M = 4.5nm anticipation, 0.8M = 6nm anticipation.

Question 12

Where would you find guidance on how to complete the flight plan request?

Answer 12

Yellow book, Sqn IREs, Ops assistants.

Question 13

If you have a programmed takeoff time of 0900, what time should you put in the flight plan under departure time?

Answer 13

10 minutes before your takeoff time (estimated off-blocks time).

Question 14

If you expect to join CAS at ROLEX at 0910, what is the tolerance for time at that point?

Answer 14

+/- 3 minutes

Question 15

Under normal circumstances, when is the latest time before startup/taxi clearance that you can submit a flight plan?

Answer 15

1 hour.

Question 16

How do you calculate a safety altitude?

Answer 16

Find the highest obstacle within 5nm of intended track, add 1000ft to the elevation and round up to the nearest 100ft. If mountainous terrain is present (>3000ft but <5000ft) then add 2000ft to the elevation of the highest obstacle. If mountain/lee waves are present due to the mountainous terrain, add 5000ft to the elevation of the highest obstacle. If mountains >5000ft in height, add an amount of clearance equal to the height of the mountains above surrounding terrain.

Question 17

What are the requirements to descend autonomously below SALT whilst IMC? What are the descent limits for your rating?

Answer 17

With a serviceable Rad Alt, >5nm from the coast on a track parallel or diverging from the coast, at least 5nm from man made objects and areas of likely airborne activity, with 2 positive position fixes (from ATC, TACAN, VOR/DME, GPS, or visually), Green rated staff pilots can descend to 750ft Rad Alt, White rated staff pilots to 1000ft Rad Alt, solo students to 1500ft (i.e. not below SALT). Alternatively, 30nm from the coast on any heading, satisfying the above criteria.

Question 18

What transponder code can you set if you are unable to communicate with ATC?

Answer 18

7600.

Question 19

How can you get the attention of ATC if your microphone has failed? Describe the procedure required to set up for an approach under these conditions.

Answer 19

Press transmit button 4 times (Morse H for Homing), either with current ATC unit or on emergency frequency. ATC will then ask a series of Yes/No questions, 1 transmission for “Yes/acknowledgement”, 2 for “No”, 3 for “Say again”, Letter X (- . . -) for “additional emergency.

Question 19

If you were cruising on a heading of 240, under IFR, below FL 290, what FL would you expect to fly?

Answer 19

Even FL (20, 40, 60 etc).

Question 20

How do you calculate the AoB required for a rate 1 turn?

Answer 20

Remove the final digit from your KCAS and add 7, e.g. 350kts = 42 degrees (rounded to 45)

Question 21

How do you calculate the required RoD for a given groundspeed?

Answer 21

Groundspeed multiplied by 5 (E.g remove the 3rd digit from your groundspeed and divide by 2, then move the decimal point two places to the right, 140kts GS = 700ft ROD).

Question 22

What classes of airspace are designated controlled airspace in the UK?

Answer 22

A, C, D, E.

Question 23

What ATC service would you expect in controlled airspace?

Answer 23

Radar Control Service

Question 24

Where might you find class C airspace?

Answer 24

Between FL 195 and FL660

Question 25

Where might you find class D airspace?

Answer 25

At or around major aerodromes and terminal manoeuvring areas.

Question 26

What is a radar corridor, where would you find one and how would you use it?

Answer 26

A method of crossing busy airways at a specified height, e.g. Lichfield RC, cross with a clearance from Swanwick Mil.

Answer 30

YLO2, No with a White rating, yes with a Green (might just get in on 25 with White!)

Question 31

What is the minimum cloudbase for a colour code of Green? Are you likely to make a successful ILS approach to land on RW 30 EGPK with that cloudbase? Can you make a successful Localiser only approach with that cloudbase?

Answer 38

Broad description of pairs of overlapping radio frequency lobes separate for azimuth and glidepath, with position with reference to the strength of signal of the two lobes determining the in cockpit indication of the ILS bars/FD.

Answer 40

Secondary surveillance radar displays traffic azimuth information on other aircraft with transponder (for mode A), including height information (mode C), and resolution advisory (if fitted). Computers in both aircraft calculate time to “collision space” based on aircraft parameters and warn the pilot as appropriate.
