Aircraft Category?

[Downwind.Maddl-Land]

Can some one advise the performance Category (presumably C or D) of a B727, please? A useful, quotable, reference would be appreciated too. :ok:

Is there an Internet site that has this information on aircraft performance Cats in one convenient place? Appreciate any inputs, its a time critical response btw and I've been looking most of the evening! :ugh:

Oh, and merry Christmas too!

A B727 is performance class A (EU OPS 1.470 (a)).

I don't have the answer for you immediately, but you have have some phraseology confused:

There are performance classes, and there are approach categories based on speed.

Performance classes are A, B and C, and most commercial multi engine operations would be class A (class B for some light twins). These are regulatory classes; ie aircraft with MTOM more than 12,500 lbs have to meet performace class A (balanced field) performance requirements.

Approach category is operational and designate A through E, based on approach speed; an aircraft is placed within these groups based on max Vref, ie 1,3 times the stall speed in the landing configuration at the maximum aircraft weight. 0-90 kt is A, 91 to 120 is B, and the rest i don't have in my head at the moment. Generally twin turboprops will be B (a few in A), while jets fall into C and sometimes D. E is usually for very fast military fighters, as a rule of thumb.

Bfisk; Sorry, target fixation and poor terminology on my behalf at the end of a frustrating day! You are absolutely correct - its the the Approach category based on approach speed that I'm after. Therefore, I suppose the real question is: What is the max Vref for the B727 - I have the other data to hand. I am trying to ascertain if the B727 was ever likely to be in Cat D, in approach terms.

Used to be in PANS OPS. Generally found in the flight information supplement for aerad or similar.
