Sometimes, airfields that said they had lights, didn't!
I once asked the controllers at Cambrige. The guy said he thought he knew where to find them.
This query prompted me to look in Pooley's, which is the only book I carrywith me in the aircraft, to check whether it did actually have crib sheets for
- light signals
- marshalling signals
- interception procedures
these all being things that you never use but might, just, be useful once in a lifetime, and was somewhat disappointed to find that it didn't. One for the next edition chaps?
(I did have to follow a marshaller once, on a weather diversion to somewhere I hadn't planned to land. He waved his arms around, I went in the direction he was pointing. Seemed to work.)
