Reversal of a TCAS RA climb or descent command when the ‘intruder’ aircraft’s flight TCAS alerts generated in situations where legitimate GA activity and VFR air routes were The Federal Aviation Administration found, very late into the implementation program,

improved RA sense reversal logic; TCAS & ATC. TCAS RA's take precedence of ATC instructions. The fact that one of the two aircraft followed ATC instructions, and the other TCAS RA's contributed to the Uberlingen accident. In case a pilot is getting a TCAS RA he should notify ATC. =====

It describes changes to the CAS logic introduced by Version 7.1 and Thus, when a version 7.1 TCAS detects that an aircraft is not responding correctly to an RA, it will issue a reversal RA to the aircraft that will then maneuver in accordance with the RA (see Diagram 2, ‘TCAS II Version 7.1 reverse logic’, courtesy of SKYbrary.) Incorporating Version 7.1 TCAs may also block the actions of other neurotransmitters, such as acetylcholine and histamine. Some TCAs affect these neurotransmitters more than others which explains why some TCAs work better for conditions other than depression or are more likely to cause side effects such as constipation, dry mouth, or sedation. TCAs are cytochrome P450 metabolized and undergo saturation in an overdose settling, leading to a prolonged half-life. Similarly they are highly lipid-soluble and widely distributed leading to a high volume of distribution and thus a long elimination half-life. TCAs typically undergo some degree of enterohepatic circulation. The TCAS II RA algorithms assume that the pilot initiates an initial 0.25 g acceleration maneuver within approximately 5 seconds. The pilot must respond within approximately 2.5 seconds if the system issues an additional RA. (You should fly any increase rate and rate reversal RAs using a 0.35 g acceleration maneuver.) A feature has been added to the TCAS II version 7.1 logic which monitors RA compliance in coordinated encounters (i.e.

TCAs typically undergo some degree of enterohepatic circulation.

TCAS RA reversals also occur because the pilot of a TCAS-unequipped aircraft changes the flight path from a climb to a descent (with unknown intentions) or while relying solely on visual traffic avoidance. Response to reversal RAs: Pilots must be prepared to respond to reversal RAs within 2.5 seconds.

NMAC, meaning TCAS caused a failure where one did not previously exist. CP112E was eventually expanded to include changes to the sense reversal logic for encounters in which reversal RAs are issued and followed appropriately, yet result in smaller vertical separation than if the reversal were not issued.

Problems with Reversal Logic. The design of the current TCAS II version 7.0 allows for reversal RAs (i.e. “Climb, climb NOW” and “Descend, descend NOW”) to be issued when the current RA is no longer predicted to provide sufficient vertical spacing.

Up Next. FIGURE 9. The Uberlingen accident might have been averted if TCAS had issued an RA reversal as shown. Responsibility for triggering the reversal rested with the Russian aircraft, which had priority and which was operating under a climb RA. But until the final few seconds, the climb RA maneuver template predicted adequate separation between aircraft; therefore, TCAS did not issue an RA reversal At that time, 27 seconds after the instruction to AF-7343, both TCAS began to highlight the crossing traffic, the pilot monitoring on AF-7343 announced "TCAS, you fly, Flight Directors Off" and both flight directors were disengaged. 3 seconds later a short term collision alert activated at the radar console of the air traffic controller. sense reversal can be issued although it would be required.
