(liscense or rating, don't know which it is) Most airlines require, or ask that you have one. Thank you!
It's neither a license or rating, it's a grade of pilot certificate. Once you have the minimum experience;
1,500 hours of total time as a pilot that includes at least:
(1) 500 hours of cross-country flight time.
(2) 100 hours of night flight time.
(3) 75 hours of instrument flight time
you may, upon recommendation of a CFI, take the ATP practical test consisting of the following:
For an airplane category -- multiengine class rating:
(i) Preflight preparation;
(ii) Preflight procedures;
(iii) Takeoff and departure phase;
(iv) In-flight maneuvers;
(v) Instrument procedures;
(vi) Landings and approaches to landings;
(vii) Normal and abnormal procedures;
(viii) Emergency procedures; and
(ix) Postflight procedures.
Consult ATP Practical Test Standards for detailed standards that have to be met. Once the experience requirements are met, there are no required amound of miniumum training time to prepare yourself for the ATP test, which can be taken in conjunction with a type rating or in an aircraft which doesn't require a type rating.
