Q – 2 Can you miss the clearance limit and loose commands from the Air Craft Officer?
Ans- Yes, there is a policy and procedure to be followed for the missing clearance limit, so a Pilot can leave and reach a different altitude for sometime within the limit and should come back to the proper clearance limit once things are in control. This time limit is only as per the procedure in the manual.
Q – 3 Without Air Traffic Control, what is the minimum descent rate can descend the plane?
Ans- A Pilot can descend up to 500” bare minimum, without informing the ATC (Air Traffic Controller) and this is only
during an exceptional cases. However, it’s always better to be in regular touch with the Air Traffic Controller and to
keep him informed about the descent rate. This will not have any traffic problems during landing in the runway.
Q – 4 When pilot is assigned a speed, how much can one deviate from that speed?
Ans- Complying and following the actual speed adjustment policies, a pilot can run and indicate plus or minus 10
knots or 0.02 mach number of specified speed. Its always better to keep the land air officer in the loop before
adjusting the air speed. Exceptions are always there to meet the emergency requirement.
Q – 5 Explain When can one deviate from any flight rules and regulations?
Ans- Chief Pilot in command can deviate from rules and regulations during emergency period; he can do it to get the
plane back to the normalcy or to meet the expected requirement of the emergency.
Q – 6 Explain What would you do if your Captain is not following the instructions properly?
Ans- Refer to your plane manual and discuss the same with your client and ensure you make him understand the procedures and
rules. If he does not respond, you will call your concerned aircraft officer at the airport and escalate and make sure your voice frequency is recorded.
Q – 7 Tell me How would you handle if your co-worker is not co-operating with you?
Ans- Talk to your co-worker directly and explain him that you are having a problem working with him and make him understand
the situation, if he is not willing to listen or not co-operating, then direct the issue to chief pilot.

Q – 34 Rotation of dc shunt motor is revers by using 2 methods,which method is best and why?
Ans- reversing the armature terminal is better & applied in practice.this is becoz of the following drawbacks in field reversing method.
* high voltage build-up during reversing the field terminal which is high enough to puncture the insulation of field coil.
* high flash-over will occur.
* during reversal, the armature current should be limited to the rated value,otherwise it will draw twice the time of starting current.we can insert the external resistance to limit the current while reversing the armature terminal.whereas,in field reversal we cannot give any provision to limit armature over current.
