what do you have to do to stay current flying jets?
 

might seem a basic question, but was talking to someone tonight about recency of experiance and neither of us know 100% what you have to do to maintain flight ready status on big jets

is it the same 90days 3 take off and landings or some 21day rule?? or other???

Currency rules are the same as any other airplane. Differences come with the type of flying (e.g., FAA Part 91 [Private/Corporate] vs Part 121 [Air Carrier]). For Part 121, it's 3 T/O's & landings in 90 days, and day/night doesn't matter.

In a company every 6 months make a check

Your ops manual will tell you! Landings for most commanders is 1 in 28 days (company rule) JAR requires 3 in 90 days as sole manipulator of controls. You also need to have a valid Licence Proficency Check (LPC) every 12 months and normally an Operator Proficency Check (OPC) overy 6 months.

In addition to the above there are the other bits and pieces such as ground school days, tech exams to ensure you are up to speed on type, safety and emergency procedures training (usually with cabin crew). Jumping down slides and firing off extinguishers plus usually a written test as well. Then there is security training plus whatever the latest and greatest want you to do on the health and safety front.

Back on the flying side of things there will be an annual line check as well with a TRE sitting on the jumpseat assessing your operation. Oh and don't forget your class 1 medical as well.

plus twice a year you'll have lvo (low viz operations) proficiency in the sim.

Quite frankly, after 42 years in professional flying, 35 of those in command of heavy jet transports, it seems to me that some of this training is rather overdone.
Of course, I could be slightly biased, as I've been on one type (L1011) for a very long time.

For Captains, once a year in the sim is plenty, as far as I'm concerned.
This every six months business is overdone, IMO.

Currency requirement for us is having flown in the last 28 days, if thats not the case we need at least one day of supervision with at least one manual landing.

Next requirement is of course the 3 landings in 90 days, but thats rather easy flying shorthaul.

Next bigger thing is every 6 months a SIM check and a LOFT session (actually first LOFT, then the check) covering the low visibility stuff as well, all systems have to be covered within a three year period.

Once a year we have to do a written test about systems and procedures, additionally there is the dreaded SEP training with a written test as well, of course we have to do one day of linetraining as well. Linecheck is to be rostered so that both crewmembers are from different bases and it has to contain at least one international sector (yes, we do fly a lot domestic stuff). We do have to do a test about workplace security, radiation security stuff etc once a year as well, just computer click and point stuff.

Every second year we have to do firefighting training and dangerous goods training and tests.

And i guess that about covers it, apart from passing the medical of course.
