AIM/Technical Flashcards
How to calculate VDP?
DME method: HAT/300 (3° GP)
Time Method: 10% of HAT
What is VDP?
defined point on the final approach course of a nonprecision straight-in approach procedure from which normal descent from the MDA to the runway touchdown point may be commenced, provided the runway environment is clearly visible to the pilot
How to calculate rate of descent for 3° path
ROD = GS/2 * 10
Standard circling radius
Cat A: 1.3 Cat B: 1.5 Cat C: 1.7 Cat D: 2.3 Cat E: 4.5
Expanded Radius identified by -C symbol on chart
Approach Categories
Cat A: less than 91 knts Cat B: 91 knts to 121 knts Cat C: 121 kts to 141 knts Cat D: 141 knts to 166 knts Cat E: 166 knts or more
Calculated based on Vref or 1.3 Vso at MLW
What is MSA?
Minimum Safe/Sector Altitude: gives 1000’ obstacle clearance usually within 25 NM of nav facility or airport reference point (ARP)
What coverage does MEA and MOCA provide?
Min Enroute Alt: lowest altitude that provides signal coverage and obstacle clearance. 2000’ over mountainous, 1000’ over non-mountainous, within 4NM of course
Min Obstruction Clearance Alt: required obstacle clearance and signal coverage within 22 NM of VOR
Lost Comm procedure
Route:
1) last ATC clearance received
2) if being vectored, direct to vector clearance
3) route advised to be expected
4) route filed
Altitude (highest of)
1) minimum IFR altitude
2) expected in further clearance
3) assigned in last ATC clearance
What is Minimum Fuel?
- fuel supply has reached a state where, upon reaching destination, you cannot accept any undue delay
- not an emergency situation
- does not imply a need for priority
- aircraft has sufficient fuel remaining to follow the cleared routing, execute an arrival and approach procedure and land with the required fuel reserves
Emergency Fuel
- The point at which, in the judgment of the pilot-in-command, it is necessary to proceed directly to the airport of intended landing due to low fuel
- priority handling by ATC is both required and expected.
