I hope that one of the navigator on today's flight JST2 from HNL to Howland Island was ready with his sextant at 0200 UTC. Flight planning was near perfect. The sun was almost dead ahead. The aircraft is about 40 nm from the 321 - 141 position line - say about five minutes flying time. In five minutes the position line will barely change (to 323 - 143) and the change in Hc is very small.
The navigater must be a risk taker as the offset is very small.
The only worry is the second (unidentified) aircraft. If that is also en-route to Howland Island I hope that the captains of each plane are following the Quadrantal rules.
PS Tomorow is the solstice.
