How should you plan the descent?
Plan all descents to arrive at traffic pattern or IAF, flaps-up maneuvering speed:
* 12 miles out straight-in approach, or
* 8 miles out abeam approach
rule of thumb is to be at 10,000 ft AFE, 30 miles from the airport at 250 kt.
DESCENT PLANNING (3° GLIDEPATH)
* Determine altitude required to lose (use straight line distance to airport)
* Distance Calculation:
– Altitude to lose * 3 / 1,000
* Required rate of descent varies proportionally to groundspeed
* Rate of Descent Calculation:
– Require Rate of Descent = Groundspeed * 5
Example:
Current Altitude FL360
Assigned Altitude 15,000 ft MSL
Altitude to Lose: 21,000 ft
TOD Calculation 21,000 * 3 / 1,000 = 63 nm
Current Groundspeed: 425 kt
Descent Rate Calculation 425 * 5 = 2,125 FPM
TOD occurs at 63 nm with a required descent rate of 2,125 FPM.
When given a crossing restriction of _____ft or less, begin descent immediately.

DESCENT SPEED PROFILE?
HOT CABIN MITIGATION DESCENT PROFILE in CRJ 200?
IDLE: Below 15,000 ft (CRJ 200), consider starting the APU and using the APU bleeds,
HOLDING In order to achieve maximum fuel economy?
- a clean configuration
- airspeed no less than VMD/Min Hold.
In situations where holding is assigned at or below 6,000 ft, VMD may exceed the FAA Maximum hold speed. In this case?
the aircraft should hold at 200 KIAS unless the Flaps 0 maneuvering speed exceeds 200 KIAS. If the Flaps 0 maneuvering speed exceeds 200 KIAS the aircraft should hold at Flaps 0 maneuvering speed and advise ATC that you are unable to comply with maximum holding speed.
Minimum holding speed?
VMD or 200 KIAS below 6,000’
Maximum holding speeds:
_____holding in icing conditions for extended periods of time.
