Question: How often should flight crews cross check the two primary altimeters when operating in RVSM?

(vii) At intervals of approximately 1 hour, cross-checks between the primary altimeters should be made. A minimum of two will need to agree within ±60 m (±200 ft).

What are the requirements for RVSM?

Within RVSMairspace (between FL290 and FL410 inclusive) the vertical separation minimum is: 1000ft (300m) between RVSM-approved aircraft, and. 2000ft (600m) between non-RVSM approved state aircraft and any other aircraft operating within RVSM airspace.

How often is RVSM training required?

The certificate you receive upon completion of this course is one method of meeting that requirement. Additionally, pilots operating under Part 91K, Part 121, and Part 135 are required to complete recurrent RVSM training every 12 calendar months.

Can you hand fly in RVSM airspace?

Yes, it must be operative to enter RVSM airspace but “operative” and “engaged” are two different things. I used to hand fly the aircraft (757,767 & 777) up to almost cruise or until I got tired of “hand flying”.

What is RVSM compliant?

RVSM was implemented to reduce the vertical separation above flight level ( FL ) 290 from 2000-ft minimum to 1000-ft minimum. It allows aircraft to safely fly more optimum profiles, gain fuel savings and increase airspace capacity.

Why is RVSM not used above FL410?

Historically, standard vertical separation was 1,000 feet from the surface to FL290, 2,000 feet from FL290 to FL410 and 4,000 feet above this. This was because the accuracy of the pressure altimeter used in aircraft to determine level decreases with height.

Is TCAS mandatory?

TCAS I is mandated for use in the U.S. for turbine powered, passenger-carrying aircraft having more than 10 and less than 31 seats. … TCAS II is mandated by the U.S. for commercial aircraft, including regional airline aircraft with more than 30 seats or a maximum takeoff weight greater than 33,000 lbs.

What is the maximum difference between primary altimeter readings in flight?

The maximum value of acceptable altimeter differences for these checks should not exceed 23 m (75 ft). Any required functioning checks of altitude indicating systems should be performed.

Is TCAS equipage specifically required for RVSM operations?

Is TCAS equipage specifically required for RVSM operations? No. What is the only standard that relates TCAS to RVSM operations? Part 91 Appendix G, Section 2, paragraph (g) is the only regulatory language that relates TCAS to RVSM operations.

Is TCAS required for RVSM?

TCAS Equipage.

Part 91, Appendix G, does not contain TCAS equipage requirements specific to RVSM, however, Appendix G does require that aircraft equipped with TCAS II and flown in RVSM airspace be modified to incorporate TCAS II Version 7.0 or a later version.

How often is RVSM height monitoring required?

Operators that have been issued an US RVSM authorization will be required to conduct initial monitoring within six (6)months of date of issue and must conduct monitoring every two (2) years or 1,000 flight hours per aircraft, whichever period is longer.

What is fl290?

FL 290 (Linzess 290 mcg)

Linzess is used in the treatment of constipation, chronic; irritable bowel syndrome; constipation and belongs to the drug class guanylate cyclase-C agonists.

Where does RVSM airspace begin?

Within RVSM airspace, air traffic control (ATC) separates aircraft by a minimum of 1,000 feet vertically between flight level (FL) 290 and FL 410 inclusive. RVSM airspace is special qualification airspace; the operator and the aircraft used by the operator must be approved by the Administrator.

What does RNP 4 mean?

RNP 4 and/or RNP 10 approval refers to long range navigational capability of an aircraft operating in remote airspace. Improved navigation capability allows for reduced lateral/longitudinal spacing along heavily used oceanic tracks particular to the Pacific airspace.

What is the difference between etops and EDTO?

Note concerning the use of the terms EDTO vs. ETOPS: It was ICAO decision, through Amendment 36, to replace the previously used term of ETOPS (for extended range operations by twin-engined aeroplanes) with the new term EDTO (for Extended Diversion Time Operations).

What is PBN in aviation?

Performance Based Navigation ( PBN ) is comprised of Area Navigation ( RNAV ) and Required Navigation Performance ( RNP ) and describes an aircraft’s capability to navigate using performance standards.
