36
# GPWS How many basic mode does GPWS have ?
Five mode: Mode 1. Excessive rate of descent Mode 2. Excessive terrain closure rate Mode 3. Altitude loss after takeoff or GA Mode 4. Terraine clearance not sufficient, if not in landing cofiguration Mode 5. Excessive descent below glide slope
37
What is the operational limit of five basic mode of GPWS ?
Up to 2500ft RA
38
What is the function of predictive GPWS ?
* Forward Looking Terrain Alerting function * Provide Obstacle database
39
How does predictive GPWS work ?
Base on GPWS database to displayed terrain infor
40
What input does GPWS use to compute geometric alt of A/C ?
* Pressure alt * RA * Temp * Barometric ref * GPS alt for **predictive GPWS** * Data from GPWS database for **predictive GPWS**
41
# GPWS What are the input of Mode 1 ?
* RA * Rate of descent
42
# GPWS What is the **caution** aural alert of Mode 1 ?
Sink rate, Sink rate
43
What is the **warning** aural alert of Mode 1 ?

66
# GPWS Are warning and caution distance of GPWS constant ?
No, it varry with ground speed and turn rate
67
# GPWS What is TCF ? | Terrain Clearance Floor
An enhance GPWS Mode 4
68
# GPWS What is TCF function ?
Compute a terrain clearance envelope around airport RWY. It will trigger alert when terrain clearance is not sufficent
69
# GPWS How does TCF trigger alert ?

72
# GPWS How does RFCF work ? | Runway Field Clearence Floor
Compute an envelop winthin a specific distance from rwy. This envelope base on geometric alt and rwy elevation. If A/C descend below this envelope, alert will be trigger.
