ATPL NAV and Radio Orals Chennai April 2013 attempt
First of all they ask is tell us about urself? what have u done? if employed? where? etc. On the basis of this they decide which questions to ask. For a fresher they will mostly stick to theoretical questions from the book whereas for an experienced candidate, questions can range from basics to practical aspects of flying(eg one A320 pilot got asked where is the location of ELT in the cockpit?)
Next question which they seemed to be asking a lot of candidates is..Where is the syllabus for ATPL oral exam? (I said CAR..)
General Nav
1) Field limited TOW?
2)Climb limited TOW?
3)What is Climb gradient?
4) If flaps are used how would it affect the TOW?
He then got into enroute charts..Highlighted an area and told me to explain everything i could see in that area
5)definitions-Mea, Moca, Grid Mora
6)Can Moca be less than Grid Mora? (Yes because Moca is only for the width of the airway whereas Grid Mora is for the entire Grid)
7)Show RNAV waypoints, compulsory reporting points, flyover waypoints
8)Explain the difference between Lambert Conformal Conical Chart and Mercator Cylindrical Projection Chart?
9)What is constant of cone? why is it used and what is its significance?
10)In lamberts if scale reduces between std parallels and is least at the parallel of origin then why do we still use it?
11)You are the captain. You are doing an ETOPS flight. What will be your action if the weather at the alternate falls below the ETOPS minima?
case 1- You are just about to enter the ETOPS segment
case 2- You are in ETOPS segment
12) What is adequate aerodrome and suitable aerodrome?which is better?why?
Radio Aids and instruments
1)How is IRS different from INS?
2)What is ring laser gyro? Draw and explain.
3)What are the errors of artificial horizon? Which type of gyro is it
4)Which type of gyro is directional gyro?
5)ASI blockage readings in climb and descent?
6)Altimeter blockage readings in climb and descent?
7)Whats the relation between frequency and wavelength?
8)What happens to speed of light as we go up? (Remains constant)
9)What happens to speed of sound as we go up?
10)Which instrument gets affected because of this?
11)If Mach no is ratio of TAS/LSS then why doesnt it get affected?
12)In LSS=38.94*sq.rt (T in degree kelvin) why is T expressed in degrees kelvin?
13)Which component gets affected more due to low temp at high altitudes static pressure or dynamic pressure?
14)Explain the working of VOR? its limitations?
15)What is DVOR? how does it remove site error?
16)What is TCAS 2? what indications does it give?
17)What do you tell the ATC when you receive TCAS RA?
18)On what instrument do you get TCAS indications?
19)Tell me another SSR instrument onboard the aircraft? (ans. DME)
20)What are the errors of DME?
21)Which type of propagation does it use? Range given by which formula?
22) Overhead the beacon what range information will DME give?
23)Which instrument gets affected because of skywaves?How does it affect?
24)At night coverage of NDB increases or decreases? till what range? (ans. decreases. we can use it till 70nm)
25)What is Mcrit?
26)Why is Mach no used after a certain level in climb?
27)Can we determine at what altitude will the coffins corner be by looking at IAS?
