05_Airborne Safety Nets

The GPWS receives data from the following systems:

• TCAS

• Radio altimeter

• Engine control computer (FADEC or ECU)

• Landing gear and flaps systems

• Radio altimeter

• Landing gear and flaps systems

TCAS assesses the closest point of approach (CPA) between two aircraft based on:

• distance

• direction

• time

• weight

time

Which of the following are airborne safety nets?​

• GPWS

• MSAW

• ACAS/TCAS

• STCA

• GPWS

• ACAS/TCAS

A pilot reports “TCAS RA". What should happen next?

• Pilot follows TCAS RA instructions.

• Auto pilot takes control.

• Pilot follows ATC instructions.

• Pilot chooses avoiding action.

• Pilot follows TCAS RA instructions.

TCAS will always present an RA if the intruding aircraft is transponder-equipped. (T/F)

False

TCAS equipment relies on signals from ground stations. (T/F/)

False

Reference TCAS. With a Traffic Advisory (TA) the pilot has identified the "intruder”. (T/F)

False

If two aircraft are equipped with TCAS II and on collision course, they will get a TA and a ​coordinated RA. (T/F)

True

TCAS alerts will not be generated in the cockpit of an aircraft equipped with only Mode A transponder.​ (T/F)

True

​In which of the following situations is a pilot allowed to deviate from an ATC clearance or instruction?

• Company request for rerouting.

• In response to a TCAS RA.

• In an emergency situation.

• In order to avoid moderate turbulence.

• To avoid a TCAS TA alert.

• In response to a TCAS RA.

• In an emergency situation.

TCAS is an airborne system generating TA and RA. The TCAS system shows the relative vertical position and approximate relative horizontal position of the other aircraft. (T/F)
