Question

Why is heave motion of the carrier not corrected in the FLOLS?

(a) Two aircraft use simultaneously

(b) Atmospheric fluctuations

(c) Too random motion

(d) Not economical

I have been asked this question in an interview for job.

I need to ask this question from Carrier Landing Systems topic in division Landing Systems & Air-Traffic Management of Avionics

Answer 1

The correct option is (a) Two aircraft use simultaneously

To explain I would say: Lens pointing angles can be adjusted to a quadratic function of heave and can be compensated. This compensation is not implemented because the “meatball” is often shared by two aircraft on final approach simultaneously.
