BNN 4A is the "official CAA published name" of this route.Needs < 230 knots and at 15,000 by SPOIT fix ahead, before turn at WCO to BNN and IAF. Flight ac001 (787) has passed the TOBID fix, heading 142, descending and slowing.Will be instructed by ATC to fly at the appropriate flight level.īNN 4A with comment BNN 4A Arrival via L10 (FL190 & below), N615 (FL90 to FL140) to HON VOR continue on HON VOR R142 to TOBID General Information 1 Standard Routes may be varied at the discretion of ATC.Ģ Cross SLPs or 3 min before holding facility at 250KIAS or less.ģ When BNN VOR is out of service the route will be to BOVVA, see AD 2-EGLL-7-4.Ĥ En-route holding at HON VOR: During periods of congestion in the London TMA trafficįrom the north may be required to hold at HON VOR.ĥ As lowest level in BNN holding stack (7000) is above transition altitude, aircraft Then SOPIT (FL150 by SOPIT) to WCO NDB then turn left onto BNN VOR R299 to BNN VOR.Īrrival via A47 (FL70) to DTY VOR continue on DTY VOR R166 to WCO NDB then turn left onto BNN VOR R299 to BNN VOR.įrom LAM VOR maintain LAM VOR R278 to DONNA then turn right onto inbound holding track 119°M to BNN VOR. There are three simplified STAR's shown below followed by general info:īNN 4A Arrival via L10 (FL190 & below), N615 (FL90 to FL140) to HON VOR continue on HON VOR R142 to TOBID BNN is about 30km north off Heathrow and also the LON vor transmitter. The Bovingdon Stack over the BNN vor, ready for Initial Approach to Heathrow.The BNN STAR is for flights arriving from the north (eg X atlantic flights).TOMMO is a fix and part of the Ockham holding pattern. ![]() ![]() LOGAN is an entry point for Biggin and Lambourne arrival.The path is a direct radial between LOGAN and LAM with TRIPO and BRASO as convinient fix's.The LOGAN Fix (rightmost to north) is the entry point and also the entry point for a Biggin arrival.Aircraft are expected to arrive at 7,000ft which is the Mimimum Holding Altitude over London and speed limits etc.Ockham (white) - for lower airspace arrival.Ockham u/s (yellow) - for S/SW arrivals (u/s denotes upper airspace).Lambourne (yellow) - for E/NE arrivals.The red H are the holding points en-route.All the arrival points below are VOR stations with the exception of TOMMO which is a Fix. The STAR's are named after their arrival point.The EGLL STAR's are for the two parallel runways 09R/27L - 09L/27R (represented by purple near center).The map below features some of the Standard Terminal Arrival Routes's ( STAR's) for EGLL London Heathrow.
