For me the OHJ is an outdated and potentially dangerous procedure which should have been ditched years ago.
It was a practice designed for the days of non radio aircraft and poor navigation equiptment.
Firstly consider the legality of an OHJ considering VFR rules and how many pilots attempt a so called OHJ when the cannot maintain VFR rules or altitudes required for the OHJ but still state they are joining OH.
Even ATC units call for the OHJ when met conditions do not legally allow it.
Aircraft cross circuit height traffic at altitudes they should not be at or break the VFR rules by scud running to the OH like bees to a honeypot almost blind.
In the OHJ the aircraft and its passengers are exposed to numerous unrequired 90 degree turns often with a mix of high wing and low wing aircraft.
This naturally increases the chances not just of midair collisions but of loss of control or disorientation.
The OHJ is uncomfortable for passengers, wasted money for pilots, burns un needed fuel for the invironment and is potentially dangerous.
It is about time the practice was chucked in the bin or declassified to just another join rather than the standard. It is about time this country moved like most others to sensible joining procedures rather than living in the dark ages.
