B737 Performance Handbook: from book to app

This site enables you to preview and to order the B737 Performance Handbook app which originally saw light as a hardcopy book (B737 PRH - Performance Reference Handbook) but is now available as iPad/iPhone app. It is an electronic reference guide for professional airline pilots flying the Boeing 737 but is also very useful for pilots of other large civil twin-jets, airline dispatchers and trainees. It explains all relevant performance matters which you come across in your operational life as a pilot, from dispatch until the final landing.

It is written by an airline pilot with an aeronautical engineering degree who is an active captain/TRI on the Boeing 737NG.


This app contains all a pilot or dispatcher needs to know about aircraft performance for large civil twin jet aircraft in general and for the Boeing 737NG in special. Due to commonality, the information in this app may also serve as reference for other Boeing types. 

Performance regulations of the worlds 2 main rulemaking agencies, EASA and FAA, are incorporated, as well as ICAO definitions and remarks.

Performance Class A

In this app general performance regulations for large civil twinjets (performance Class A) is explained as well as performance data and application methods for the Boeing 737NG in special. See preview for more details.

Although it is common practice nowadays to have computerized tools available for performance computations, this app may still serve as a source of information to keep you familiar with the full meaning of the calculations you have (or your computer has) made.

Useful operational tools

Besides reference and explanatory information, this app contains also a Tools section with various handy tools which makes the pilot life easier (see preview for a short demo video):​

  • Landing Distance & Brake Cooling Time Calculator for various B737 types

  • Go-Around Climb Gradient & Limit Weight Calculator for various B737 types

  • Actual Stop Margin Calculator based on the TAS (True Airspeed) effect with visualization.

  • Wind Components & Vref Additive (Approach Speed) Calculator with easy animated input of runway- and wind direction.

  • Runway Condition Report Decoder based on Global Reporting Format (GRF) 

  • Interactive V1 visualization

"The 737PRH makes 737 performance transparent and understandable to pilots like me, for whom performance has always been some kind of black hole.  I finally got to understand some performance issues that have been obscure to me for many years !  The book comes in handy format and excellent layout.  Well done, Maurits, I recommend your guide to all 737 pilots !"
