IN205 Descent and Penetration

True or False? When performing an enroute descent you should specify the type of approach you desire.

True

What does performing a pilot discretion descent allow the pilot to do?

start the descent when the pilot chooses; use any rate of descent; level off at an intermediate altitude

You are in a 4 degree descent angle and your airspeed is .4 Mach. What is your VSI rate of descent?

1600 fpm

Where are instrument penetration approaches found?

FLIP Terminal High Altitude books

Can you fly the HI-TACAN RWY 31L approach in the T-6?

No - can't fly TACAN approaches in the T-6

What is the penetration airspeed in the T-6?

200 KIAS

If no penetration turn altitude is depicted on the approach plate, when will you begin your turn inbound on a non-DME teardrop penetration?

At an altitude halfway between IAF and FAF altitude

You are cleared for a non-DME teardrop VOR penetration but are 3000 feet below the published IAF altitude. How long will you time outbound before descending?

45 seconds

When flying a radial approach, what should you do as you pass the IAF?

turn immediately in the shorter direction toward the approach course

True or False? When flying high altitude radial/arc penetrations, you should calculate and use normal lead points to complete required course/arc intercepts.

true

What section of the approach plate provides a side view preview for the altitude restrictions?

profile view

The non-DME teardrop approach is usually associated with a ____ approach.

VOR

When flying a non-DME teardrop approach, you are required to maintain a pitch attitude _____ below the level flight picture for the penetration airspeed to ensure you remain within protected airspace.

8-10 degrees

When flying a radial approach if your heading is within ____ of the outbound penetration course, you are not required to overfly the IAF and may use normal lead points to intercept the course.

90 degrees

If you have a 3 degree descent gradient, how much altitude have you lost in 1 nautical mile?

300 feet

When flying a radial/arc approach, when may you begin your descent to the next applicable altitude restriction?

once a lead point is reached AND a turn to the next approach segment is initiated

You are 40 miles from Junction at FL310 at .5 Mach and are required to cross Junction at 15,000 feet. How will you determine your descent gradient?

Divide the altitude you have to lose in hundreds of feet by the number of miles you have to go
160/40 = 4

What is the benefit of an enroute descent?

allows transition from enroute cruising altitude to final approach without entire FLIP IAP;
expedites traffic movement;
minimizes fuel consumption

When you are in an enroute descent and cleared for the approach, when can you change heading and altitude?

maintain last assigned altitude and heading until established on a segment of the published approach

One degree of pitch change equals _____ feet of altitude per nautical mile.

100

What formula can you use to determine your descent gradient?

GS (NM/min) x 100 x descent gradient

What symbol indicates a precision FAF?

lightning bolt

What symbol indicates a nonprecision FAF?

Maltese cross

What is the Missed Approach Point?

point at which missed approach procedures shall be executed if required visual references do not exist

What steps should be accomplished prior to arrival at IAF?

W-HOLDS
Weather
Holding clearance
Obtain approach clearance
Letdown plate review
Descent check
Speed as required

If you are established in a published holding pattern at an altitude above minimum, when may you descend to the minimum and commence the approach?

immediately upon receiving clearance

What is the term for the lowest altitude to which descent is authorized on final approach or circling to land?

Minimum Descent Altitude (MDA)

You are flying an approach where the holding fix and IAF are not colocated. ATC gives your approach clearance while enroute to the holding fix. Where should you go next?

proceed to the holding fix and then to the IAF, unless ATC clears you direct to the IAF

When performing a teardrop, when should you set the inbound course and verify direction of the penetration turn?

1,000 feet above penetration turn altitude

When can you be considered "established on course"?

within half full-scale deflection (one dot on EHSI)

When should you plan to start configuring?

2-3 miles from FAF

What should you have accomplished prior to crossing the FAF?

Lowered landing gear and TO flaps, completed before landing check, slow to 110 KIAS
